摘要 高水头抽水蓄能电站中,常采用一洞多机系统,所以机组之间水力联系紧密,本文建立了对水力干扰进行过渡过程计算所必须的既能进行大波动计算又可进行小波动计算的数学模型,并编制了计算程序,通过计算研究了部分机组停机过程中,其余机组在水力干扰下的过渡过程及稳定问题. In this article, the mathematical model for calculating the hydraulic transient in multimachine conduit system is established. This model can be used both for the case of tremendous load fluctuation and small load turbulence.The transients and their stability of the remaining machines in the hydraulic turbulence processes of the shut down of one or several machine are also studied. It is showed that the stable area is different from one of small load turbulence, and if the parameters of governor are optimum for load turbulence, the remaining machines are stablized under hydraulic turbulence.
