Abstract
China has built or under construction a number of pumped storage power stations with water head of 400 meters section,single-unit capacity of 300WM and rated speed of 428.6rpm.In this paper,the pump turbine model test in four pumped storage power stations are compared and analyzed,the result shows that each parameter index of power station C is advanced.In order to make parameter matching more reasonable,it is suggested that it is not appropriate to over-pursue the rated point efficiency and the pressure pulsation index in the leafless zone,and it is not appropriate to raise the hump margin and the safety margin index in the S zone,so as to meet the requirements of stable operation.The recommended bidding parameter of each index proposed in this paper can provide reference for the subsequent similar projects with this speed in bidding.关键词
