Chengdu's investment grid to welcome the peak summer key project will improve the power supply capacity of the southwestern area of Chengdu

Today, the main transformation project of the 500 kV substation of Guangdu was successfully put into operation. This project is a key project in Sichuan Power Grid. The project's investment will meet the needs of load growth in the Southwest area of ​​Chengdu to a certain extent, effectively alleviate the power supply pressure on the peak power consumption, and improve the power supply capacity and power supply reliability of the area.

It is understood that Chengdu Power Grid is the largest load center of Sichuan Power Grid, and 500 kV power grid operates in Shuanghuan. Guangdu 500 kV power station is a hub substation of Chengdu Power Grid. It is the main power supply of multiple 220 kV substation. Power supply task. After the project was put into operation, the substation capacity of the station increased from 2.4 million kilowatts to 3.6 million kilowatts, which can further optimize the structure of Chengdu's power grid and add new energy guarantee to Chengdu's economic and social development.

The project began construction in October 2021, and was transferred to the installation stage of electrical equipment in February this year. It began to enter the test and acceptance stage at the end of May.

During the construction process, the installation of the new equipment and the replacement of the old equipment are carried out simultaneously. The working conditions are complex and the operating surface is cross, especially the installation of GIS equipment has strict requirements on temperature, humidity, and dust -free environment. Nearly, it also increased the difficulty of on -site construction. Since late June, Chengdu has ushered in high temperature weather, and the highest temperature has reached 40 ° C, which has brought a lot of challenges to the construction, commissioning and acceptance of power workers. To this end, the State Grid Sichuan Electric Power Construction Company and State Grid Sichuan ultra -high -voltage company carefully organized construction, grasped and safely controlled, integrated the power of construction management and transport inspection personnel, overcome various difficulties such as high temperature weather and short construction periods, quickly promoted the construction of the project, comprehensively comprehensively Investigation and resolution of equipment defects and safety hazards ensure the investment of zero defects of the main transformation project of Guangdu 500 kV power station.
