On September 25, the last unit of the Shenzhen Pumped Storage Power Station was put into commercial operation, marking the first large-scale pumped storage power station built in a very large city in China. The deep power station is the focus of China's renewable energy development plan. The construction project is also the connection point between the West Power Transmission and the Guangdong-Hong Kong power grid. The commissioning of the power station is of great significance to the economic and social sustainable development and ecological environment construction of the Guangdong, Hong Kong and Macao Dawan District. It is expected to save standard coal every year. 15.8 million tons, saving 18,300 tons of natural gas, reducing the total greenhouse gas emissions by about 2717.28 tons.
The deep power station is located between Yantian District and Longgang District of Shenzhen City, about 20 kilometers away from the center of Shenzhen. It is about 25 kilometers away from Hong Kong, Daya Bay Nuclear Power Station and Ling Ao Nuclear Power Station. The estimated static investment of the power station project is 4.948 billion yuan and the total installed capacity is 120. Ten thousand kilowatts (4x300,000 kilowatts), designed to generate an annual average of 1.511 billion kilowatt-hours, to undertake power system peaking, valley filling, frequency modulation, phase modulation and emergency standby tasks.
As the core city of Guangdong, Hong Kong and Macao, the economic density and energy density of Shenzhen are among the highest in the country. The deep power station can meet the peak demand of nearly one-third of the Shenzhen power grid. After the full-scale power station is put into production, it is equivalent to the Pearl River Delta. Add another load center, and adjust, the rapid response force that stops, not only helps to optimize the power supply structure, reduce transmission costs, meet the increasing peak demand of the system, improve nuclear power, thermal power operating conditions, It will help to fully absorb clean power, ease the load pressure of Shenzhen and even Hong Kong power grids, and improve the safety and economy of power grid operation.
The deep power station is a comprehensive development project. The power station hub project has the functions of pumping power generation, urban water supply, etc. According to the introduction of the Southern Power Grid Peaking and Frequency Regulation Company, the deep reservoir substation adopts the cooperation with the local water bureau to utilize the expansion of the Tongluojing Reservoir. The reservoir also has the function of urban water supply, which promotes the comprehensive utilization of water resources. In order to ensure that the power station emissions do not cause reservoir pollution, the deep storage power station design and implementation of the sewage separation and drainage system, and strive to maintain a friendly ecological environment.
In addition, all aspects and processes from the planning and design of the power station incorporate the concept of environmental protection. During the implementation process, the layout of the buildings and the layout of the construction facilities are continuously optimized to minimize the occupation of forest land and maximize the protection of the original ecology. The power station will design environmental protection and water conservation facilities simultaneously, and implement them simultaneously and simultaneously. After the completion of the power station, it has become another beautiful landscape in Shenzhen. It has created a tourist attraction for the development of industrial tourism and the construction of leisure tourism and popular science education. condition.
The deep power station is fully invested by China Southern Power Grid Corporation. The Southern Power Grid Peaking and Frequency Control Company is responsible for the construction. It is the construction of the Southern Power Grid in Guangdong Province after the construction of the Guangzhou Pumped Storage Power Station, Huizhou Pumped Storage Power Station and Qingyuan Pumped Storage Power Station. The fourth pumped-storage power station is also the first fully-designed, manufactured, installed and commissioned pumped-storage power station of China Southern Power Grid. Its full-scale operation has also accumulated rich experience for the optimization design and commissioning of domestically produced units.
