该文以某抽水蓄能电站水泵水轮机调速器控制应用为例,简要介绍了调速器功能特点以及控制模式,描述了蓄能机组调速器在水轮机、调相和拖动机等工况下导叶控制情况,详细分析了水泵工况下导叶开度与接力器行程和抽水扬程、机组流量和频率之间的关系,从而计算出抽水扬程与导叶开度之间的关系,通过实践检验得到与各工况运行条件相适应的导叶调节方式。
Taking the pump turbine governor control application of a pumped storage power plant as an example, this paper introduces the function and control mode of the governor briefly, and describes the working conditions of the governor of the accumulator, such as turbine, phase modulation and drag Under guide vane control situation, a detailed analysis of the pump working conditions guide vane opening and the relay stroke and pumping head, unit flow and frequency of the relationship between the pumping head and the guide to calculate the relationship between the opening of the guide through Practice test and get the working conditions of each condition guide vane adjustment method.
