On June 28, at 220 kV Shuping Power Power Station in Shangyang, Shuping Town, Ziguai District, Zigong City, the staff of the State Grid Zigong Power Supply Company was intensely conducting the final test after the transformation and upgrading of the substation. At the end of June, this large -scale upgrade transformation station for the first time in more than 30 years will be put into operation in the critical period of the peak summer to meet the increasing demand for hundreds of thousands of residents from the Liujing District and the surrounding areas.

Since its operation in June 1990, the 220 kV Shuping substation has the first or secondary equipment, the various types of equipment are inconvenient management, and the serious insufficient transport capacity of some transmission lines has affected the reliability and safety of power supply. , Safety production pressure is high, and upgrades are imminent.

It is understood that the transformation of this substation is composed of two parts: expansion projects and comprehensive reconstruction projects. Among them, the planned period of the expansion project is from September 2021 to June 2022. March 23. The main work content includes the main change of the main change, the overall renovation of 110 kV of the outlet, and replacing the entire site monitoring and five defense systems to improve the work content of the scheduling data network equipment and electrical energy collection system. This project is the largest and longest duration of expansion and comprehensive reconstruction projects in Zigong Grid. In the face of long construction cycle, wide range of power outages, high transformation equipment, high power grid risks, etc. Essence

The 220 kV Shuping substation is located in Shangyang, Shuping Town, Ziliujing District. It is closely linked in the same area. It is an important part of the earliest 220 kV backbone grid shelf in Zigong City. It is also the only 220 kV substation in Zijing District. At the same time, the station has been launched for 220 kV and 7 times, and 90 kV is 9 times. It is one of the main power points of Zigong Power grid. It shoulders the important duty of Zigong Grid to protect people's livelihood.

In order to ensure the successful completion of the project, relevant departments and units cooperate and cooperate closely. Before starting, repeated field survey and risk assessment, carefully analyze the dangerous points and weak links, strictly implement the "three, four inspections, and five prohibitions" of the maximum load of lifting equipment and cranes, formulate comprehensive preventive measures, construction plans, and construction plans, and construction plans. Emergency disposal plan, pay close attention to the delivery of materials, and improve the safety access examination, training and safety technical intercourse. Especially in terms of power outages, because this time the power outage involves many engineering projects and many major participation majors. In order to thoroughly implement the requirements of "one stop and multi -use", relevant professional departments, workshops and construction units have been discussed, fully considered, repeated demonstrations, and science. Arrange the power outage method, coordinate the construction time, to avoid repeated power outages to the greatest extent, and reduce the power outage time.

In the construction of the past 10 months, the participating units have carried out solidly on -site construction and safety management, and do a good job of creating the atmosphere of "party building+production safety". The risk points formulate corresponding pre -control measures in advance, make a record of each danger point, carefully analyze the response, so as to achieve closed -loop management. At the same time, a special seminar discussed the possibility and reliability of each installation plan, determined the optimal construction plan, and formulated a number of safety measures to ensure that the on -site work was conducted in an orderly manner.

After the transformation, the 220 kV Shuping substation will greatly improve the level of equipment technology and lean management level, vigorously improve the reliability and safety of the power supply station, reduce the annual operation and maintenance cost of the substation, and achieve the "resources of resources Save and environmental friendship. "

Through this upgrade and transformation, it will greatly meet the growing demand for new loads of new electricity in Zijing District, improve the 220 kV capacity ratio ratio of the "N-1" power grid, greatly improve the 10 kV power supply power supply in the surrounding areas Low -voltage problems such as low radius, completely resolving the contradiction between supply and demand, ensuring the safe and smooth summer of the power grid, and providing a solid important support guarantee for the leapfrog development of Zigong's urban construction.
