| 摘 要： | 带调压室水电站发生负荷扰动时,其机组频率波动可分为主波和尾波,调压室水位低频振荡所引起的尾波是影响调节品质的主要因素.本文建立了机组频率的尾波波动方程,推导了调节品质域的计算公式,分析了调压室面积及调速器参数对调节品质的作用.研究表明:调压室面积越大调节品质越好;增大调速器参数对调节系统的稳定性有利,但恶化了系统的调节品质.

| Abstract: | When the hydropower station is with surge tanks,the frequency fluctuation caused by load disturbance can be divided into major wave and stern wave.The stern wave which is caused by low frequency oscillatory in surge tank is the primary factor of the governing quality.In this article,a model of rotational speed of stern wave has been established,a calculation formula of stern wave has been deduced,the effects of cross-section of surge tank and the governor parameters on the governing quality are analyzed.The... |
