Expand the scope of professional skills appraisal enterprises and identify the types of work, so that the team of skilled personnel of the group company has been comprehensively improved.

Third, the enterprise identification process

In the aspect of carrying out the appraisal: At the beginning of each year, the group company issues the annual occupational skill appraisal work plan, which clarifies the types of work, time, training and other items to be appraised this year, so that the employees have targeted learning and are fully prepared to participate in the appraisal work. .

The examination and examination are closely integrated with the actual production and construction of the enterprise. With the rise of the leaps and bounds of railway development in recent years, the introduction and promotion of various new technologies and new products, combined with the characteristics of production and engineering projects of enterprise automatic control systems, railway microcomputer interlocks and zpw-XXa products, The exam question bank is updated in a timely manner, with emphasis on the application of new knowledge, new theories, new technologies, new techniques, etc., so that the examination and examination is more in line with the actual production and construction.

After the employees who apply for the third, fourth and fifth grades have passed the qualification examination of the enterprise assessment station, they will organize the corresponding training. After completing the prescribed time, they will conduct evaluations on the employees through the theoretical examination and skill assessment. The theoretical examination adopts the method of limited time, written test and closed book. The test papers are randomly selected from the self-owned test bank of our station; the skill assessment needs to be combined with the actual production, and the typical workpiece processing method is adopted. After the examination, the theoretical test papers and the processed workpieces are sealed and sealed. The members will be closed and enrolled. If both of the results are qualified or above, they will be awarded the corresponding professional qualification certificate.

For employees who apply for the first and second-level appraisal, in addition to conducting theoretical examinations and skills assessments, a comprehensive review is required. The enterprise technicians and senior technicians review committees conduct comprehensive evaluations on the employees' main work performance and operational skills. Its content involves solving production process problems, completing work tasks, mastering technical expertise, technical competitions, technological innovations, organizing technical training and imparting skills, etc., and finally voting by each jury, agreeing that the number of votes exceeds the number of attendees. 3, can be reported to the group company review meeting for review.

Support and strengthen technical services.

Summary of work of electric technicians

I entered the xx power supply company in 1998, and was the first batch of personnel on duty to build the first 500kv substation. In order to enter the role as soon as possible, during the internship, I was directly assigned to the 220kvxx substation to study. The learning of xx made me gather my theoretical knowledge and actual scene for the first time. I started with a device simulation board familiar with the main control room, step by step to understand the various components of the substation, and also know how to patrol and monitor. Screen, then to simple operations and invoicing. Now I want to come. In that period, I only mastered a little bit of knowledge about the operation of substation, and I have a little understanding of the effects of various types of primary equipment. As for the secondary protection of relay protection and anti-missing, it is only the pressure plate to retreat, but for me. Now the work on the 500kv station has laid a good foundation and let me know the hard work and responsibility of a duty officer.

The company attached great importance to the preparation work of the first 500kv substation and carried out a lot of training work for us. I also benefited a lot. At the same time as the internship at xx, I also participated in various training activities organized by the company, such as the different drawings of the national and internal equipment, as well as the method of reading pictures, the training of manufacturers of equipment in the station, the training of manufacturers of relay protection, and the state of x. The simulation training of the Electric Power Training Center and the East China Electric Power Training Center has also been carried out for a few months in the field of 500kvxx in xx province and 500kvxx in the first automated substation in xx province. Because of my familiarity with computers, I was also sent to NARI to participate in the computer rd-800 system and to study the monitoring system with Shanghai Huian and remote operators.

In May 2002, I passed the positive test of 200kvxx change, and at the same time transferred the xx change and entered the work of the 500kv preparatory group. In the preparatory group, I was responsible for the automation system of the 500kvyy change. The understanding of the automation system was further deepened. The production of the yy change, the secondary automation system monitoring wiring diagram and the light signal signal diagram and the telemetry curve were completed. The rd-800 system real-time database only supports the name of 15-bit tuple. Many event names are larger than 15 bytes, and it is impossible to input the real-time database. However, the manufacturer's programmers only have the full name of the design institute, and do not know how to abbreviate the operation requirements. For this reason, I simplified the translation and classification of the more than 3,000 event names in the whole station. The names that can be abbreviated are not included in the event name library as much as possible, and the system is running faster. This finishing work allowed me to have a comprehensive understanding of the whole station light plate, telemetry, and remote control volume, and further understand the configuration and data flow of the system database, laying a solid foundation for handling the abnormality of the monitoring system in the future. Before the yy became operational, I completed the preparation of the yy variable integrated automation part and obtained the affirmation of the leadership.

In February 2001, 500kvyy was put into operation. During the start of the xx line, I was responsible for monitoring and actually checking the operation of the monitoring system. When I started the zero-voltage boost, I turned on the rd-800 real-time telemetry monitoring tool and found that the phase a voltage was sharp. If the situation is abnormally high, report to the on-site start-up committee immediately, stop the boost, and check the line for internal pressure failure. The avoidance of this accident I think is inseparable from my understanding of the rd-800 system. Because the system normally monitors the load, the database is stored in the library for 5 minutes and stored as historical data. If we directly call the telemetry curve monitoring, the graph is displayed every 5 minutes, not in the full sense of "real time" because If the system really refreshes the telemetry data in real time, the total station data volume is very large, and the computer system occupancy rate is very high, which may cause the loss of the remote signal. The real-time telemetry monitoring tool I called can be set to refresh the data in 3s. Although it can't be counted in the historical database, it can't be queried later, but the actual telemetry data can be learned in time to find the problem in time.

After I entered the operation in 2001, I took up the job at the station. In 2003, I was the duty monitor. In the process, I handled several accidents. Such as the monitoring system lost station monitoring, switch leakage nitrogen, 500kv busbar switch rejection, 220kv line, 500kv line trip, 35kv cable ignition single-phase grounding and timely prevent the main transformer 35kv export three-phase short-circuit accident, 220kv low variance Voltage blocking, etc. The handling of these accidents and abnormalities complemented my theoretical knowledge well, which made me further understand the first and second circuits in the station. It also made me realize that there are many practical things in the station. My understanding and understanding are still very good. Unfamiliarity has prompted me to learn more about the lower level and to have a deeper understanding of primary and secondary equipment. In the process of learning while working, I learned more deeply the characteristics and principles of the busbar protection in the station, the voltage switching circuit of the 220kv double-female wiring, and the comparison and analysis of the 220kv and 500kv protection configurations. Check drawings, wiring, and relay protection, AC and DC system problems may be carried out a large number of accidents and use the simulation system in the station to carry out possible anti-accident exercises, analyze the reasons for the light board signal and circuit wiring Have a more direct understanding of the ins and outs of the light card. It also gave me more confidence in the work of duty.

In the actual study, I got the help of the master in the station. For example, the 35kv system cable I successfully handled was on fire, and the single-phase grounding was abnormal. In the past few months, I happened to do this during the simulation exercise. As a long-time inspection, the personnel who went out to check the equipment all shocked “death”. The stationmaster later analyzed the reason: the single-phase grounding inspectors did not. Safety measures, and asked me to analyze the possible grounding point, grounding phenomenon and judgment check of 35kv. If the main transformer 35kv side is single-phase grounded, and the overcurrent protection will not move, how to check and judge, how to judge the low neutral point side grounding? It is this normal exercise of the monthly routine that made me encounter the real afterwards. There is no disorder in the anomaly. This exercise made me deeply aware of the importance of safety: a small accident handling inadvertently may cause a few lives! After that, the first thing I considered when I was in the accident was the safety of life: such as the inspection of ct open road, The use of insulation mats, inspection of the use of safety equipment, etc., because the danger is really at random moments. The safety measures of the power system are complete, but they are also obtained from many personal and equipment accidents. Therefore, I have increased the practical understanding of various safety measures in safety regulations, and paid great attention to the work and developed good habits. . Also pay attention to handing these good habits to newcomers.

After yy was built, xx went on three consecutive substations, and the operating personnel were very nervous. In order to put the new station on duty, more excellent duty officers were dispatched, leaving new recruits, at least There are only three people in my class: I, at the right time, the sub-values ​​that have been tested in half a year. Bringing a class is the focus of work and a guarantee of safety. I have taught my own knowledge and the actual situation in the station to the positive and negative values ​​of the class, and conveyed the safety focus. For example, the operation of the retrial must have a finger nameplate, a three-level electroscope, and leave the site to re-examine. The accident is not expected to float on the surface, and it is necessary to conduct in-depth research, just as the master taught me strictly and seriously. The questions they raised also prompted me to further study and study, let me pay attention to and study some problems that I did not notice. Secretary of Secrets 114 Copyright

In the past few years, I have experienced these stages in the years of running and working. In the first stage, 220kvxx changed. This gave me a preliminary understanding of the running work, and I have a certain foundation, and I have actual comparison cases for further study in the future. At the same time, this old station that has been operating safely for decades has taught me the magic weapon of safety: harmonious team relationship and strict implementation of rules and regulations. In the second stage, during the training period of preparation for 500kvyy, we received various types of factory training and design institutes, and various professional experts gave lectures. The theoretical knowledge and understanding of new equipment have been greatly improved. In the third stage, we have a positive value. In the stage of the shift, he handled many accidents and participated in the acceptance of various equipments, and the actual experience was greatly improved.

At the end of 2004, I carried out 500kv expansion of two lines, added a main transformer, and the 220kv system was changed from double busbar bypass to double busbar double section with bypass. I participated in the whole process of equipment acceptance. Through this inspection, I also found many dead ends of acceptance, and I need to further standardize the acceptance process. During the start-up and commissioning of the New Year's Day equipment in 2005, I served as the squad leader of the on-site operation. I was in charge of the whole process of starting the operation. Although it has been more than 30 hours before and after, it is very hard, but the harvest is very large, responsible for dispatching, and The on-site start-up committee reports, coordinates with the on-site commissioning personnel, arranges the operation personnel to operate, from the pre-launch layout of the operator, the temporary fixed-value check, to the equipment nuclear phase, impact test, on-load voltage regulation test, mother-to-difference protection test, and then Finally, I contacted the local authorities, obtained the operation report, and finally coordinated the command work with the load operation. I experienced the start-up and commissioning process of the equipment.

While doing technical work, I also participated in other aspects of the team. In 2004, the computer image monitoring system was optimized and reorganized, and the qc won the first place in the company. This year, the re-writing of the typical ticket for the AC and DC system in the station was completed, and the statistical work of the accident signal for relay protection was being carried out, which facilitated the on-duty staff to retrieve the signals that may be protected under various circumstances and improve the speed of the accident handling. The misunderstandings and acceptance methods in the acceptance of the automation system are summarized, and reasonable suggestions are put forward.

The work of substation operation is a very responsible job, and it is also a highly technical work. It is by no means what the average person thinks is just “doing things according to the rules”, and it is not “everything that understands everything and does not understand everything”. In the future, the trend of power reform requires that the on-duty personnel appear as the “master” of the equipment, and the requirements for the operational personnel are higher, requiring the operational personnel to have independent judgment and processing capabilities. I have to go a long way to become a qualified operator in the new period. On this road, I will demand myself with higher standards, implement safe and stable operation, and take the lead in the team. Management takes the lead and truly the owner of the equipment.

Summary of the work of the centralized control technician

I graduated from Jiangxi Electric Power Vocational and Technical College in July 2007 with a major in electrical engineering and automation. In January 2007, I entered Inner Mongolia Jinglong Power Generation Co., Ltd. to work in centralized control operations. In these five years, through my hard study, hard work, careful summarization, fine operation, and strict requirements, I gradually grew from a centralized control intern to a versatile deputy in centralized control operation. Of course, this growth process is also inseparable from the support and help that leaders and colleagues have given me in work and life, so that their own thoughts, work, study and other aspects have achieved certain results, and the overall quality of individuals has also been certain. Improve, here is a comprehensive and comprehensive summary of my work over the past five years from a professional and technical perspective:

The thermal power generation enterprise is a special industry, especially as a relatively large-scale large-scale thermal power generating unit in China. It requires every working employee to have good self-abilities and psychological qualities. When I first joined the work, I deeply understand that the centralized control operation is like a thin ice. As the reason of the abyss, I continue to learn various operational skills related to electrical, boiler, steam turbine, and thermal control systems, and strive to master the operation modes and characteristics of each related system, and fully understand the situation of each device and system, The operation status of the equipment and system, comprehensive analysis and judgment of relevant operations, timely selection of the best safe operation mode and economic operation method according to the operation of the equipment, according to the actual operation conditions, the application procedures require timely and correct handling of the equipment failure of the unit and system burst Sexual accident. After 5 years of work and study and experience accumulation, we have gradually gained a comprehensive understanding and understanding of the centralized control and operation of large-scale thermal power generating units.

First, learn professional knowledge and improve job skills

From the beginning of my work in 2007, I found that the professional knowledge I learned in the school is very different from the actual production, and the professional knowledge I have learned is very limited. Interdisciplinary knowledge, such as boiler, steam turbine, thermal control. The related content is basically a blank sheet for me. When I realize these shortcomings, I clearly know that I must work hard to learn and work hard to make up for these shortcomings. Through the systematic learning and control, I run professional knowledge. Efforts to improve my post work skills, in a short period of one year, I took the initiative to absorb the work experience of the masters, humbly ask them for technical problems in their work, and through their own efforts, quickly mastered the centralized control of various equipment and The specifications and parameters of the relevant systems have a certain understanding of the system operation mode and accident handling. In May 2007, our generator set began to enter the comprehensive installation and trial operation section. Under the leadership of the company's leaders and masters, I was put into work with a high degree of work enthusiasm. Although the daily work is very tired, I can't To satisfy the passionate heart that I just joined the work, in the year of 2007, I participated in the trial operation of the company's No. 1 and No. 2 coal-fired direct air-cooled 600MW thermal power units, and 168 hours at the end of the year. Safe trial operation to achieve dual-machine grid-connected power generation. While participating in the installation and commissioning work of the crew, I also participated in the drawing of the company's electrical, boiler and steam turbine system diagrams under the recommendation of the department leaders. This work made my CAD drawing in school have a place. And through the drawing of the system diagram, the system flow has a more comprehensive understanding and understanding. After drawing the system diagram, I participated in the typesetting work of the company's crew operation rules. This process enabled me to learn a certain basic knowledge of operation and operation. Through the systematic training and learning, I have obtained the intermediate skill certification certificate for the dispatching and dispatching duty of the Northern United Power Vocational Qualifications. Through training and learning, my professional skills have been greatly improved. It laid a good foundation for me to participate in the work better.

In 2008, the company's crew entered full normal operation. After one year of professional technical training, I passed the assessment and became an official centralized control inspector. After 2 months of system training and learning, I obtained the Advanced Skills Recognition Certificate of the North Union Power Vocational Qualification Control and Control Operator. After this training, my professional skills have been improved. In the same year, he also participated in the production and release of the company QC, and won the excellent results in the group company QC evaluation. In August, I went to Shanxi Guodian Power Datong Training Center for training and training, and obtained the 600MW thermal power unit simulation machine omnipotent duty officer certificate. The simulation machine training and learning rewards a lot, so that my system has mastered the 600MW thermal power unit centralized control operation. all content. During the year, he also participated in the company's employee skills competition and achieved excellent results. Participated in the company's electrical operation ticket editing work, so that our company's electrical operation ticket management has entered a standard process from the non-standard state, the electrical operation ticket repair work has been fully affirmed by the company, the qualified and standardized electrical operation ticket is To ensure the personal safety of the operation and maintenance personnel, the necessary basic elements of the safe and stable operation of the unit, by participating in the revision of the electrical operation ticket, I have a comprehensive understanding and understanding of the electrical system of the whole company, and I will regulate the electrical aspects of the future. A solid foundation has been laid. At the same time, I used my own knowledge of CAD and relative knowledge of equipment and systems to make a lot of corrections to the deficiencies in our company's system diagram, and made a unified revision and rectification of KKS code. Praise. After becoming a formal omnipotent inspector of the company, I understand that my responsibility is heavy. I have never dared to slack off. Through hard work and careful operation, my professional knowledge has been improved in all aspects. A lot of major equipment defects, one of the most impressive things was that during the start-up of Unit 2, it was found that the high-pressure seal oil backup pump outlet temperature reached 150 degrees, because it was found in time, avoiding a major accident, and the post-treatment treatment found a high-pressure seal. Oil reserve pump outlet regulator valve cartridge. The accident made me realize that the responsibility as a patrolman is significant, and that my own negligence will cause irreparable damage. After this accident, I raised the requirements for my work. I must carefully inspect a piece of equipment without leaving any hidden dangers and control the accident in a bud. August 2008 is a very unforgettable year for all Chinese people. Because this year's Olympic Games is held in China, Olympic power conservation has become the biggest responsibility of every electric worker. During the Olympics, I strictly demanded myself. To standardize each of its own operations, after two months of joint efforts of all the leading employees, our company successfully completed the Olympic power conservation task.

Second, work excellence, and actively advocate technological innovation

In 2019, I passed the company's many training assessments and became a deputy watchman of the centralized control omnipotent duty officer. In the busy work, I formed a good study habit, and ended each operation earnestly, so that every operation is improved. I deeply know that every operation is not the best, but I have always asked my next operation to be better. After becoming a deputy watchman, there are many operations on the centralized decentralized control system. Because of the relatively good work of the production site, the company participated in many technical innovations, energy conservation and consumption reduction work during the production line, such as in the operation of steam turbines: Because the swinging amplitude of the condensed water water regulating door is relatively large, the flow of condensed water is unstable, which seriously affects the safe operation of the unit, and causes a large noise and a serious swing of the pipe when oscillating. The initial solution is to slightly open the condensed water water bypass electric door to ease the swinging trend. This kind of swing is caused by the system design, caused by the flow pulsation. After running for a period of time, it was found that the condensed water bypass power gate was seriously worn, and the unit consumption of the condensate pump was relatively large due to design reasons. Under such circumstances, after research, I proposed to carry out frequency conversion transformation on the condensate pump motor. After the company's leadership and relevant technical personnel jointly demonstrated, through the feasibility study, the company carried out frequency conversion transformation of the condensate pump motor, through one year of operation observation and analysis, the water electric door swing problem in the condensate system was completely solved, and the condensate pump single The consumption has dropped drastically and has been recognized by the company. Boiler: The large-scale newly installed four-corner-cut boiler has a relatively low temperature of reheat steam. I have conducted a large number of boiler soot ash optimization tests and combustion adjustment tests with our boiler experts, and will reheat steam. The temperature has been increased by about 8 °C, and the coal consumption of the integrated power supply of the unit is reduced by about 0.64g/kWh. According to the annual power generation capacity of the unit of 6.5 billion kilowatt hours, 4160 tons of standard coal can be saved every year, which can be saved according to the standard price of 400 yuan/ton. The cost is 1.64 million yuan. Electrical aspects: The dust removal equipment installed by our company is two double-row, four-chamber five-field electrostatic high-efficiency electrostatic precipitators. In normal operation, full-wave operation mode is adopted, but this operation mode has higher operating voltage and current, energy consumption. Larger, because our company's fly ash is a high specific resistance dust, long-term operation is prone to corona closure, so that dust removal efficiency is reduced. Since May 2019, I have learned through several experiments that the operation is carried out with a single half-wave gap power supply mode, and the safe operation of the unit can be guaranteed under the premise of ensuring that the dust removal efficiency does not change much. After two months of statistical analysis of the dust removal efficiency and energy saving of the #2 unit, after the company's leadership review and approval, I changed the operation mode of the electrostatic precipitator from the full-wave operation mode to the single-half-wave gap power supply mode. After more than half a year of running data statistical analysis, it can fully guarantee the safe and stable operation of the unit.

Third, the thinking keeps pace with the times and echoes the national energy conservation policy

In 2019, the state promulgated the policy of energy conservation and consumption reduction. Our company is a large-scale thermal power generation enterprise. It is a large energy-consuming household, and it is the unshirkable responsibility of each of our electric power people to do energy conservation and consumption reduction work. Through running the analysis, I participated in a lot of energy saving and consumption reduction work of the company. The auxiliary circulating cooling water system of our company adopts the secondary circulation water supply system with mechanical ventilation cooling tower. The water supply mode is expanded unit system, two units are equipped with one cooling tower, and there are 3 auxiliary machine circulating water pumps, 2 sets of running 1 Standby. In addition to the machine side vacuum pump and the main engine lubricating oil cooling water directly supplied by the auxiliary machine circulating pump, the other open cooling waters are supplied to the user through the two open cooling water pumps with a capacity of 200 kW. According to the water consumption of each cooling water user and the cooling water pressure, Jinglong Power Generation keeps the open-type cooling water pump inlet and outlet electric door open during the trial operation of the unit, stops the operation of the open cooling water pump, and can also meet the cooling water demand, saving the plant hourly. Electricity is about 180kWh, calculated according to the tax-free electricity price of 0.2435 yuan / kwh, the unit operating hours of 7200 hours, the entire plant can increase net income of 631,000 yuan. Each unit of our company is equipped with 3 sets of electric water supply pumps of 50% capacity of FK4E39M type produced by Shanghai Electric Power Repair General Factory Co., Ltd., starting from the trial operation of the unit, when the unit load is greater than 300MW, the second feed pump will be started, and the other will be started. Standby, and in order to meet the requirements of the steam on the steam drum, to ensure the safety of the unit, the thermal logic is realized. When the unit load is greater than 350MW, if one feed pump trips and the standby feed pump is not linked, the RB protection is triggered and the unit is automatically reduced. The amount of fuel corresponding to the fuel to 300MW. From the operation of the unit, two feed pumps below 400 MW load were found to operate, and each feed pump had a large margin for current and flow. By carrying out the load capacity test of the feed water pump, it is concluded that each feed water pump can carry a long-term safe operation with a load of 420 MW when the steam drum water level is relatively stable and the back pressure is 15 kPa. In 2019, our company changed the heat control logic of the feed pump, and made the above adjustments to the operation mode of the feed pump. So far, our company's water supply system has been in a safe and stable operation state. In the first quarter of 2019, the water replenishment rate of the whole plant was 3.31%, which was energy-saving through the recovery of the new coal-fired steam and steam, the hydrophobic recovery of the boiler heater to the deaerator, the water ring vacuum pump, the water separator, and the water recovery to the exhaust system. In the first quarter of 2019, the water replenishment rate of the whole plant decreased to 1.31%, the water replenishment rate decreased by 2%, and the coal consumption for power generation was reduced by about 3 g/kWh. According to the annual production of 6.5 billion kWh of electricity, the annual savings of 19,500 can be saved. Tons of standard coal, calculated according to the standard price of standard coal of 400 yuan / ton, can save costs of 7.8 million yuan. After four years of work and study, I got a lot of work to bring me happiness.

A lot of work has been recognized, which is also a contribution to my contribution to society. In September 2019, I and the company's leaders and some technical personnel participated in the Beijing Enterprise Management Modernization Innovation Achievement Competition, which presented me in the results display. In recent years, the company has achieved gratifying achievements in technological innovation and energy conservation and consumption reduction. The paper published is “Building a New Model for Energy Saving and Consumption Reduction of Thermal Power Enterprises”, which was highly recognized by the Beijing Enterprise Management Modernization Innovation Achievement Evaluation Committee and won The second prize of the 25th Beijing Enterprise Management Modernization Innovation Achievements.

Fourth, do a good job of unity and cooperation, train electric power running talents

For example, in the past half year of 2019, from a centralized control and running omnipotent trainee intern to today's centralized control duty officer, in the past five years, there have been bitter and sweet, work tired and acquired knowledge. It’s really nothing, my father often said: “It’s a great fortune for a young person to eat and suffer, no matter when, think more for others”. When I think of this sentence, I will think of the leaders and colleagues who have been concerned about my work and life during the past five years. I will thank you all here. The road ahead is still very long. As a front-line worker in power production, I deeply understand that there are still many shortcomings in various aspects, and I need to study harder and work harder. In the future, I will continue to maintain my youthful vitality and contribute my own strength to the bright future of the electric power industry. This is the technical summary of my work for five years.
