Ensuring the power load in the high-cold area, the highest latitude pumped-storage power station in my country is put into operation and power generation

　　How to solve the problem of pumped-storage power station operation in high-cold areas?

Yesterday (20th), my country’s highest latitude pumped-storage power station-Unit 1 of Heilongjiang Huanggou Power Station completed 15 days of trial operation and officially put into operation for power generation.

This has also accumulated experience for my country's construction and operation of pumped-storage power stations in high-cold areas.

　　The pumped-storage power station put into operation for power generation is located in Hailin City, Heilongjiang. The local extreme minimum temperature is -45.2℃, the maximum frozen soil depth is 1.91 meters, and the maximum ice thickness is 1.65 meters. It is a typical high-cold area.

　　Pumped-storage power station, as the "battery", "stabilizer" and "regulator" of the power grid, is to build two reservoirs up and down the mountain, pumping water and storing electricity when electricity is low, and releasing water for electricity generation when electricity is peak.

　　In order to ensure normal operation at low temperatures, the most advanced anti-freezing technology in the country has been adopted in the construction of the power station, and the low temperature resistance of the power station dam can reach -50°C.

At the same time, the power station is closely cooperating with Heilongjiang power grid dispatching, and through measures such as shortening the shutdown time of the units, it is ensured that the water inlet and outlet areas of the upper and lower reservoirs are not frozen, and the units can be started and stopped at any time.

　　According to reports, the total installed capacity of the power station is 1.2 million kilowatts, and the designed annual power generation capacity is 1.836 billion kilowatt-hours. It can generate peak power at the peak of the power grid and bear one-third of the peak power load in Harbin to ensure the safe and stable operation of the power grid.
