水电站保证出力是水利发电一个十分重要的运行参数。在水电站运行多年后,需要对水电站的保证出力进行复核,以便更好地指导水电站的运行。复核计算保证出力的方法包括等流量法和等出力法,等流量法适合日调节水电站;等出力法适合于年调节及多年调节水电站。基于等出力法的不足,将二分法的思想应用于等出力法计算保证出力的过程中并对其进行改进,将改进后的计算方法应用于实例计算分析,结果表明二分法和等出力法相结合的计算方法能有效地求解水电站的保证出力。
水電站保證齣力是水利髮電一箇十分重要的運行參數。在水電站運行多年後,需要對水電站的保證齣力進行複覈,以便更好地指導水電站的運行。複覈計算保證齣力的方法包括等流量法和等齣力法,等流量法適閤日調節水電站;等齣力法適閤于年調節及多年調節水電站。基于等齣力法的不足,將二分法的思想應用于等齣力法計算保證齣力的過程中併對其進行改進,將改進後的計算方法應用于實例計算分析,結果錶明二分法和等齣力法相結閤的計算方法能有效地求解水電站的保證齣力。

Guaranteed output of hydropower station is an important running parameter for hydroelectric power.After run-ning many years,it requires to carry out check for guaranteed output of the hydropower station in order to preferably guide operation of the hydropower station.Methods for check calculation on guaranteed output includes equal mass flow method which is suitable for daily-storage hydropower station and co-output method which is suitable for annual storage carryover storage hydropower stations.Due to shortages of co-output method,idea of dichotomy was applied in calculating guaranteed output by co-output method and improving co-output method.The improved calculation method was applied in example cal-culating analysis and the result indicated that the calculation method combining dichotomy and co-output method could effec-tively work out guaranteed output of the hydropower station.
