According to the website of the State-owned Assets Supervision and Administration Commission, recently, Sichuan Chunchangba Pumped Storage Power Station, the first cascade hydro-optical storage combined power station in China, was officially connected to the grid for power generation, marking the first variable-speed constant-frequency pumped-storage unit in China to achieve full power operation.

Sichuan Chunchangba Pumped Storage Power Station is located in the Chunchangba Hydropower Station which has been put into operation. It uses the existing Chunchangba Reservoir and its water diversion system in the upstream and the existing Sanguanqiao Reservoir in the downstream to build a new pumped storage power station, and installs a variable speed constant frequency reversible pumped storage power station. Pumped-storage generator set.

According to reports, the smooth commissioning of Sichuan Chunchangba pumped-storage power station marks that the first variable-speed constant-frequency pumped-storage unit adopted by the power station has achieved full-power operation, and has overcome the optimal configuration and connection of the capacity of my country’s cascade water-photovoltaic-storage complementary power stations. The world’s technical problems, supporting the development of the world’s first cascaded water-photovoltaic hybrid power station joint operation control and intelligent dispatching system.

In addition, after the power station is put into operation, it is expected to generate economic benefits of 112.22 million yuan per year, increase photovoltaic power generation by 2.25 million kWh, save about 909 tons of standard coal, and reduce carbon dioxide emissions by about 2,273 tons.
