| 摘 要： | 本文提出了必须把大小波动分析统一起来的观点,不单是为了使用程序的方促,而是考虑二者之间的本质联系。指出水轮机调节系统是非连续的,这与通常的说法迥然不同。提出了利用水压反馈降低水压、减小调压室稳定断面的设想。还就具有分叉管道的调节系统的稳定性研究进行了讨论。预计把水机电联合过渡过程分析应用于电站设计中,将有利于合理解决安全、稳定和经济的矛盾。

| Abstract: | This paper puts forward a viewpoint that the simulation programs for analyzing large and small disturbances must be united for their essential relationship and not only for convenient use, It points out that turbine-governing system is non-continuous, which is utterly different from the general viewpoint about it. The envisagement of the water column feedback for lowering the maximum water column and decreasing chamber's area is advanced. Analysis on stability of the governing system with branch pipes is also discussed. In the writerts' view, it is a inexorable tendency to apply the analysis of joint transients to solve to station design rationally the contradictory between safty, stability and econoical index. |
