进行水轮机调节保证计算时,均假定导叶按等速线性方式关闭。关闭时间T_s按设计水头H_p、额定出力时的工况进行整定。一般情况下,调节保证主要计算两个控制工况的水锤升压和速率升高,即设计水头发额定出力和最高水头发额定出力时两种工况,计算结果取最大者作出保证。一般前者发生最大速率升高,后者发生最大水锤升压。由于设 When calculating the regulation of the turbine, it is assumed that the vane is closed in a constant speed linear manner. Close time T_s according to the design head H_p, the rated output when the working conditions set. Under normal circumstances, the adjustment guarantees that the two main control conditions of the water hammer to increase the pressure and the rate of rise, that is, the design of the water hair rated output power and the maximum water hair rated output of two conditions, whichever is the largest calculation to ensure. The former general maximum rate of rise, which occurred the largest water hammer pressure. Due to set
