摘要
Abstract
Hydroelectric power stations with large head fluctuations have obvious problems of unstable operation,and a large number of power stations have also experienced operational accidents such as blade rupture and tailwater cone tube damage.Therefore,the size of the rated head affects the stable operation of the turbine in different head sections and the long-term safe operation of the unit,and also has an impact on whether the hydropower station can fully utilize water energy.Based on the engineering example of PNZ hydropower station,this article analyzes the selection of rated head for the power station from the perspective of turbine stability and engineering characteristics.关键词
