摘要
调压室的几何形状与断面尺寸是和水头损失是密切相关的,减少尾水调压室的水头损失是优化调压室系统设计的重要内容之一。对待建及已建电站的调压室的稳定性进行分析,具有非常重要的现实意义。文章讨论了"理想"调速器情况下,忽略压力管道水流、机组和负载频率的调节过程中,调压室所需满足的断面要求。最后,重点探讨了不同水位波动情况对调压室的稳定性的影响。研究结果对调压室断面的确定具有重要的指导意义。
As the geometry and section size of the surge chamber are closely related to its water head loss,to decrease the water head loss of the tailrace surge chamber becomes important in optimizing the surge chamber system.Therefore,it is necessary to carry out the stability study on the surge chamber.The section area that it must adhere to is analyzed given the ＂ideal speed governor＂,overlooking the regulation of penstock flow,unit and load frequency.Finally,the surge chamber stability is analyzed under different water level fluctuations.Accordingly,the conclusion obtained helps determine a rational section size for the surge chamber.
