摘　　要：对梯级水电站水能计算方程中各要素及梯级电站丰水期、枯水期、平水期的发电水头和机组工作情况进行了研究。以某梯级水电站为例,计算了无调度和有调度时的发电效益。结果表明:在不进行调节的情况下,全年发电总量为316.75亿kW.h;在进行调节的情况下,全年发电总量为327.11亿kW.h,增发效益为2.59亿元,效益增加近3.3%。The elements of equation of hydropower computation and the water heads, operating conditions of high-water period, normal-water peri- od, and low flow period were discussed. Based on one hydropower station, generate electricity benefit with regulation and non-regulation was calcu- lated. The result shows that ： with out regulation, the total energy output of hydropower station in a regulation year is 31. 675 billion kW· h ; with regulation, the total energy output of hydropower station in a regulation year is 32.711 billion kW · h; the increase value of benefit is 0. 259 billion RMB, increasing almost 3.3%.
