| Abstract: | The Baoquan Pumped storage Power Plant has the installed capacity of 4 300 MW, the annual energy output of 2 010 TWh, the annual water pumped energy consumption of 2.642 TWh and the comprehensive efficiency of 0.76. In the design of the plant, the following several key technical problems have been solved. Due to the large seepage volume of the upper reservoir, the local overburden layer in the bottom of the reservoir has been excavated and backfilled by quarry rubbish and clay as blanket to control seepage. The asphalt concrete has been used in the bank seepage control of the upper reservoir. Because the original dam of the lower reservoir has been heightened and strengthened, the reinforced concrete face slab has been adopted for seepage control, which solves the problem of underwater construction. Due to different rock properties in different sections of the water conveyance tunnel, manifold lining types have been adopted. The rated speed of the generating unit of 428.6 r/min is selected. |
