Summary of technical work of power supply limited liability company

In December 1985, he recruited to work in the North Gate Substation of Yifeng County Small Hydropower Company, engaged in substation operation and overhaul work. In 1991, he took the National Adult Self-study Examination and obtained a law degree in law in October 1994.

After coming to the substation, the biggest problem is to integrate the theoretical knowledge and practice that I have learned. From the familiar equipment simulation board of the main control room, I will understand the various components of the substation step by step, and know how to Patrol, monitor screen, and then simple operation and billing. And constantly add new energy. It is difficult to get the knowledge and experience of on-site operation from books. It is inevitable that you should look at it, think more, ask more questions, and strive to not only know it but know why it is, and become a "one-purpose multi-purpose" talent. In order to be able to learn in the substation operation, I will touch the equipment during the day and read the instructions at night. Through learning, from the fuzzy understanding of the work of substation operation, to the combination of professional knowledge and on-site practice, and more skillful completion of work; through the study of various safety regulations, procedures, regulations, to enhance knowledge reserves; through learning, the previous operation of the company Nothing to know, now can focus on company dynamics, industry dynamics, and broaden their horizons. 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 I have laid a good foundation for the work in the dispatching and running positions, and let me know the hard work and responsibility of a duty officer.

In 1987, the company carried out technical transformation of the Beimen Substation. The company attached great importance to this and carried out a lot of training work for us. I also benefited a lot. During this period, I also participated in various training activities organized by the company, such as different reading methods of equipment drawings, on-site training of manufacturers of equipment inside and outside the station, and on-site training of manufacturers of relay protection.

Since 1988, I have served as the duty representative of the North Gate substation. During this process, I handled several accidents. Such as switch rejection or rejection of the switch, switch oil leakage, knife brake heating and other failures. 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, and my understanding and understanding. Still unfamiliar, I am going to learn more about the lower level of things and to have a deeper understanding of primary and secondary equipment. In the actual study work, I got the great help from the masters in the station, and also let me have more firm confidence in the operation and maintenance of the substation.

In 1988, the secondary relay of the secondary part of the Beimen Substation was burnt out continuously. I carefully observed and analyzed that it was caused by unstable system voltage. I strengthened the voltage monitoring and increased the number of contacts of the intermediate relay and increased the contact. Capacity, and no intermediate relay contact burnout has been found since then, avoiding economic losses.
Through the work over the past few years, I have realized that maintenance of electrical equipment should be done:

1. Careful observation, through the eyes can be found abnormal phenomena of the equipment, such as rupture, broken wire, deformation, oil leakage, discoloration, corrosion and other abnormal phenomena.

2. Listening to the nose and hearing, due to the action of the alternating current, it generates vibration and emits a unique sound. Through the characteristics of the sound change, it is judged whether the device is operating normally. Smell is also a method of discriminating sensitive to certain abnormalities and defects in electrical equipment.

3. Touch the device being inspected by hand to judge the defects and abnormalities of the device. By touching the hand, you can feel the change and vibration of the equipment temperature, such as the temperature change of the transformer, local heat, relay heat, vibration, etc., can be checked by hand touch.

4. Understand the operating conditions, the weather changes in the event of a fault, the size of the load, and the records and solutions for similar faults.
Through these, you can quickly grasp the most basic conditions of equipment operation, facilitate the complete handling of accidents, avoid accidents and find work into misunderstandings, extend power outage time, and expand the scope of accidents.

In December 1994, as the best power transmission and transformation personnel, he was selected to work in the power dispatching station of Yifeng Hydropower Company. He is mainly engaged in power system operation and dispatch management. Through years of dispatching work, he has mastered the power system power safety regulations. Dispatching procedures, electric power law, power grid management regulations, etc.; has the ability to independently analyze the operating conditions of the power grid, handle various accidents, and ensure the safe and economic operation of the power grid.

In May 1995, he served as the long-term dispatching operation value, mainly engaged in power grid dispatching operation and management. He was responsible for analyzing the operation status of this value grid, handling various faults, and ensuring the safe and economic operation of the power grid. Through the calculation of the main transformer loss, the main economic operation was drawn. The graph is used to reasonably carry out the scheduling of the substation main economic operation mode. For example, the two main transformer economic operation integration points of Dongmen Substation are 65a current. When the main transformer current is greater than 65a, two main transformers should be put into operation. When the main transformer current is less than 65a, only one main transformer operation is required. By this mode, the operation is reduced. The loss of the main transformer increases the economic benefits of the company. In addition, according to the county's power grid, the small hydropower is relatively abundant, and the line is characterized by mountains and mountains. Rational use of small hydropower resources, scientific scheduling, requires two large power plants to report daily storage capacity, timely report rain conditions, equipment, report equipment maintenance plans, require other small hydropower to report daily power generation plans and declare equipment maintenance plans. We often go into small hydropower customers in various ways to master the power generation and equipment of our customers and to close customer relationships. In the work, adhere to the "fair, just, open" scheduling, rationally arrange the grid operation mode, maintenance planning, and strive to improve the reliability of power supply.

In the study of power grid technology and relay protection knowledge, humbly ask for advice at the level of the level, work hard, study the theoretical knowledge hard; in the work practice, through the study of the neighboring county to the local level and their own efforts, participate in the county The annual operation mode of the power grid, the economic dispatch plan, and the load control measures; participated in the revision of the “Provisional Regulations for the Power System of the County”, and drafted a copy of the “Grid-connected ESC Agreement” and other power grid management. In the past two years, the county power grid rules and regulations, safety management, operation management, operation management, equipment management, quality service and other management work have been established and improved; the power grid dispatch management of our county has been standardized, so that our company's power grid dispatch management Going up to a new level.

It has been more than 20 years. These 20 years have been the period of continuous maturity and deepening of my outlook on life. From a substation operator to a dispatched duty officer, after continuous efforts, with the expansion of the power grid, equipment has increased, and the line is complicated. I always realize that my knowledge is poor. The dispatching office is the department of operation mode and technical management. All the links are full of technology . In order to make myself better able to master the technology of my position and improve my technical level. In order to master the new theory, on the one hand, use various materials for professional study, and strengthen their own professional knowledge in a targeted manner. On the other hand, ask the teacher for questions that are unclear, and do diligently, do more, study hard, keep in mind, I can make myself more confident in the operation status of the equipment and add a lot of work confidence to myself.

In general, scheduling operations is a highly responsible job and a highly technical job. In the future, the trend of power reform will have higher requirements for dispatching duty personnel. It is necessary to have independent judgment and processing capability for equipment operation. To make yourself a qualified dispatcher in the new period, it is necessary to strengthen business learning and overcome Disadvantages, so that their professional and technical standards can be continuously improved, more able to adapt to the needs of modern power construction.
