en.Wedoany.com Reported - The 500 kV switch station of the Dadu River Shuangjiangkou Hydropower Station under China Energy was officially put into operation recently, laying the foundation for the entire station to achieve its power generation target. The switch station is the core of the Shuangjiangkou Hydropower Station's power transmission and distribution project, responsible for the collection, distribution, and transmission of electric energy, and is equipped with a full set of high-voltage electrical equipment including 500 kV circuit breakers and disconnecting switches. As a key point in the transmission channel for the Shuangjiangkou and Jinchuan hydropower stations, it is also a prerequisite core condition for the commissioning of the generating units at Shuangjiangkou, directly impacting whether the units can be connected to the grid on schedule.

To ensure the smooth commissioning of the switch station, Shuangjiangkou Company, in collaboration with participating construction units, precisely controlled stages such as equipment debugging, system integration testing, safety inspections, and energized trial operation. Operators strictly followed a dual-supervision mechanism, executing dispatch instructions step-by-step and verifying equipment status on-site, successfully completing key steps like line phase verification and busbar energization with high quality. During the trial operation period, duty personnel monitored equipment operating parameters throughout the entire process, investigated potential operational hazards, and ensured the safety, stability, and reliability of the switch station's entire process.

The commissioning and operation of this switch station marks a significant milestone in the construction of the Shuangjiangkou Hydropower Station, opening up the station's power transmission channel and laying the groundwork for the subsequent safe commissioning of generating units and the safe and efficient transmission of electric energy.
