摘　　要：混流式水轮机因其固有的特性,存在某些范围的水力不稳定运行区域,对这些运行区域的准确划分有利于电站的运行调度。运行区域的划分不仅要从机组运行参数方面综合考虑,还要综合考虑电站的实际运行情况、调节的便利性及电网的具体要求等其他因素。瀑布沟水电站装设了两种不同机型的水轮机,从设计水头和模型试验结果,预估了两种机型不同的运行特性,基于水轮机运行区域命名和划分的一般原则,结合实际情况,对比分析了瀑布沟水电站两种水轮机运行区域的主要影响因素,据此得出了两种水轮机的全工况运行区域。Due to its inherent characteristics,Francis turbines have certain hydraulically unstable operation areas.The accurate division of these operation areas is beneficial to the operation and scheduling of the power station.The division of the operating area should not only comprehensively consider the operating parameters of the unit,but also comprehensively consider other factors such as the actual operation of the power station,the convenience of adjustment,and the specific requirements of the power grid.Two different types of turbines are installed in Puggou Hydropower Station.From the design head and model test results,the different operating characteristics of the two types of turbines are estimated.The main influencing factors of the operating areas of the two types of turbines in Puggou Hydropower Station are analyzed,and the operating areas of the two types of turbines under all operating conditions are obtained accordingly.
