摘要 高水头抽水蓄能电站一般为长管道多机组的复杂系统,机组上游压力即蜗壳水压力对机组的控制极为重要。现提出用原有调速器作为压力反馈环节进行压力控制,来完善关闭规律的方法,在计算机上用数字仿真的方法说明其有效性,最后还讨论了调速器参数对控制效果的影响。 Normally the high head pumped storage station is a complex of long conduits and multiple units. The water pressure upstream of the units or the water pressure in the scroll is of great importance to the control of the units. The text suggests that using an improved speed governor as a feedback link to execute the water pressure control. The numeriCal emulation by the computer shows that this method is effective. In the text the influence of the speed governor parameters on the control effect is also discussed.
