For the South river ,their runoff is volume, and has a low sediment content ; while the northern river has a smaller runoff, and the water sediment is bigger. And this power station in hydropower make runoff calculations more difficult, this thesis let the Lingbao Qingyuan Hydro Energy calculated as a example, make a analysis for hydro power station on runoff calculation method . The outcome of the paper is as follows: (1)According to the Zhai Kou reservoir runoff series ,obtained using hydrological simulation method get the Qingyuan power station's late traffic data. (2)Use the area ratio method , hydropower runoff calculation algorithm and the list of a simple method, calculated the corresponding design flow capacity, the average generating capacity. (3)Consider the turbine's prices, hydroelectric power generation efficiency and other economic indicators, to determine the best design flow generation, installed capacity and the average generating capacity. ????? ?
