Guangzhou Pumped-storage Power Station Pumped-storage Power Station Tourist Resort is 5 kilometers away from National Highway 105 5 and 60 kilometers away from Conghua Street. Engineering information: The upper and lower reservoirs belong to Liuxi River system. Shang Reservoir is located in the Chenhe River Basin in the upper reaches of Zhaodashui River, with a rainwater collection area of 5 square kilometers above the dam site, with an average annual flow of 0.209 cubic meters per second and an average annual runoff of 6.6 million cubic meters. Lower reservoir is located in Xiaoshan basin in the upper reaches of Jiuqu River. Dam site area 13 km2, with an average annual runoff of 0.544 cubic meters per second, 1.7 1.6 million cubic meters. The topography of the upper reservoir is a natural reservoir basin, and most of the bedrock forming the reservoir bottom and bank is granite, and only a small amount of sand shale is distributed in the southeast corner of the right reservoir tail, which is in close contact with each other. Most faults are small in width and filled with well cemented tectonic rocks; Groundwater is supplied to the reservoir, so it will not leak out of the reservoir after storage. Although limestone is distributed at the bottom of the lower reservoir, it is surrounded by granite mountains and is a closed residue. The faults around the reservoir and leading to the outside of the reservoir are generally small in scale and well cemented; Groundwater supplies the reservoir, so it won't leak out of the reservoir. The upper reservoir dam site has narrow valley, strong mountains on both sides, granite, single lithology, small fault structure and superior geological conditions. The foundation stone of the lower reservoir is also granite, the alluvial layer of the river reservoir is thin, the fully weathered and strongly weathered zones on both sides of the hillside are not deep, and the rocks in the weakly weathered zone are hard. Although faults are developed, it still has good dam-building conditions. According to the Guangdong Earthquake Administration, the basic earthquake intensity in this power station area is 6 degrees. The lithology of the water diversion system is mainly medium-coarse grained biotite granite, with a small amount of lamprophyre veins and fine grained granite veins. F2, F4, F 109, F 1 10 and other large NW-trending faults. The geological conditions of the diversion tunnel are mainly controlled by faults and altered rocks, and it can be divided into four sections along the line, including the second section (2+0 10 ~ 2+500) and the fourth section (2+9 10 to the entrance and exit of the lower reservoir). The lithology of underground powerhouse is granite, so we should try our best to avoid F4 fault and its nearby F 179 and dense alteration zone. Since the implementation of the special economic policy in Guangdong Province, industrial and agricultural production has developed rapidly, with a sharp increase in electricity load, a wide peak-valley difference and a low minimum load rate (b = 0.5 1). Guangdong power grid is dominated by thermal power, and most thermal power units are high-temperature and high-pressure condensing coal-fired units with high minimum technical output, which should only be arranged in the base load; At the same time, after Daya Bay Nuclear Power Station is put into operation, it is only suitable for base load operation from the perspective of safety and economy. Therefore, it is urgent to build a pumped storage power station near Guangzhou, which is close to the load center, in order to increase the peak-shaving capacity of the power grid and cooperate with the construction of nuclear power and large-capacity thermal power plants. It is proved that the installed capacity of the energy storage power station is 654.38+200,000 kilowatts. After the power station is put into the system, it plays the role of peak-shaving and valley-filling, making the nuclear power station run at full load all the year round, and the low-valley electricity will be changed into peak-shaving electricity (in 2000, the low-valley electricity will be changed from 310.38 billion kW h to 2.38 billion kW h peak electricity), which will increase the income from electricity sales; More economical than thermal power peak shaving; It can also improve the economic operation conditions of the system (the annual operation cost can be reduced to about 6,543.8+0,000 tons of standard coal in 2000, and the waste water power can be used more by about 900 million kW·h), providing the system with spare capacity, which has remarkable power, economic and social benefits.
