The Yuecheng II500 kV switch station of the Panxi optimization project is about to be put into operation.
The reporter learned from the State Grid Sichuan Electric Power Company,On December 9, the 500 kV switch station of Sichuan Power Grid Yuecheng entered trial operation, which marked the completion of the second phase of the construction of Sichuan Panxi Power Grid Optimization Project.
The switch station is one of the important facilities of the power system, and unlike the substation, the switch station does not have the function of voltage regulation. The switch station mainly optimizes and adjusts the power transmission and other transportation conditions of each transmission line through a series of switchgear, and plays a role in optimizing the operation of the regional power grid.
Sichuan Panxi Power Grid brings together multiple hydropower transmission channels in southwest China, which has certain systemic safety risks. Since September 2022, the State Grid has implemented the 500 kV Panxi optimization project in Sichuan, optimizing the grid structure of the Panxi power grid in five stages, enhancing the Panxi power grid's ability to resist extreme failures, further upgrading the Sichuan power grid, and strengthening the energy backup in southwest China.
On December 3, in the Yuecheng II500 kV switch station of the Panxi optimization project, the construction personnel were installing the wire.
The optimization and transformation of Panxi power grid is equivalent to the implementation of a 'surgical operation' on the power grid in Panxi, straightening out the 'blood vessels' of the power grid and rebuilding a 'heart'. Xu Qianjie, deputy manager of the project department of the project owner, said. The 500 kV Yuecheng switch station plays a key role in connecting the upper and lower levels and connecting the entire Panxi power grid optimization project, which is the "heart". The commissioning of the Yuecheng switch station will effectively alleviate the operating pressure of the original Yuecheng 500 thousand volt substation of Panxi Power Grid, effectively guarantee the reliable power of Sichuan this winter and next spring, meet the needs of large-scale clean energy development, transmission and consumption in Panxi, and transform regional energy advantages into economic advantages.
Construction crews are working on the installation of conductors.
The new project of the switch station is large-scale, heavy construction tasks, many cross-operations, high technical requirements, in the peak period of construction, on-site civil engineering, substation, commissioning three professional operators at the same time more than 500 people. Du Yuxiang, project manager of the project construction, said. In order to ensure the safe and high-quality progress of the project on schedule, during the peak period of construction, roads, bridges and sidewalks were built inside and outside the 500 kV Yuecheng II switch station at the same time to ensure the smooth entry of the main equipmentAdopt grid management of safety production, and supervise key nodes, paths, and links by specialty to ensure the safety and efficiency of cross-operationsThe innovative design of the mobile inflatable dust-free installation shed ensures that the installation of core equipment meets the dustproof requirements through five dust removal measures.
Construction crews are in the process of installing an equipment.
It is understoodNext, Sichuan Power Grid will continue to promote the remaining three phases of the Panxi Power Grid Optimization Project, and it is expected that all transformation tasks will be completed in June 2025Further upgrade the Sichuan power grid to provide stronger power guarantee for local economic and social development, and serve the optimal allocation of clean energy on a larger scale.
