水轮机的效率评估计算是水电站机组机型选择论证的主要内容。常规的算法一般是根据个别水文代表年和负荷设计水平年典型日的水轮机运行工况进行计算,有时甚至只是按电站水头和机组技术出力范围在已有的水轮机效率
Turbine efficiency evaluation and calculation is the main content of hydropower station model selection demonstration. Conventional algorithms are generally based on individual hydrology years and years of typical load-bearing design of the turbine operating conditions to calculate, and sometimes even only by the station head and crew technical output range in the existing turbine efficiency
