Brief introduction of Shenzhen pumped storage power station

Shenzhen Pumped Storage Power Station is located between Yantian District and Longgang District in Shenzhen, about 20 kilometers away from downtown Shenzhen, and about 25 kilometers away from Hong Kong, Daya Bay Nuclear Power Station and Ling 'ao Nuclear Power Station. It is located in the power load center of Guangdong Province. At the same time, it is the landing point of power transmission from west to east and the connection point of Guangdong-Hong Kong power grid. The installed capacity of the power station is 4×300MW, with an estimated static investment of 4.948 billion yuan, dynamic investment of 5.979 billion yuan, and the construction period of the main project is 69 months. Shenzhen Pumped Storage Power Station Hub Project is mainly composed of upper reservoir, lower reservoir, water conveyance power generation system, underground powerhouse cavern group and other auxiliary projects. The maximum dam height of the main dam of the Upper Reservoir is 55m, and the regulated storage capacity is 8.25 million cubic meters. The Upper Reservoir Area is located in the Xiaosanzhou Basin in the north of Yantian District, covering an area of 640,000 square meters. The Lower Reservoir was rebuilt by expanding the capacity of Tongluojing Reservoir in Longgang District. The maximum dam height of the main dam is 50m, and the regulated storage capacity is1.625m3. The lower reservoir area is located in Tongluojing Reservoir in Henggang Street, covering an area of 990,000 square meters. The connecting road between the upper and lower reservoirs is10km long. Four 300,000 kW vertical shaft single-stage reversible mixed-flow units will be built in this project, with a total installed capacity of 65,438+200,000 kW and an average head of 448 meters. The power stations will be connected to Shenzhen Substation and Yuanfeng Substation through four 220 kV outgoing lines respectively. The regulation performance of the power station is daily regulation, with full-time daily regulation of 6.37h and full-time emergency standby1h. The annual pumping power consumption of the power station is 65.438+95.5 million kWh, and the annual power generation is 65.438+0.51.1100 million kWh.
