1985年7月受福建省电力局委托,我们承担了“六五”重点工程沙溪口水电站单机7.5万千瓦大型轴流转桨式水轮机装置甩负荷与起动过渡过程的研究课题。该项研究包含两个内容:1.寻求一种合理的控制方式,使甩负荷过程机组转数上升与蜗壳水压上升值最小,从而获得经济效益;2.确定水轮机合理的导叶起动开度与轮叶起动转角,使起动过程迅速、轴向
In July 1985 entrusted by Fujian Provincial Electric Power Bureau, we undertook the research project of load shedding and start-up transition process of the large-scale axial-flow propeller turbine unit with a capacity of 75,000 kilowatts in Shaxikou hydropower station. The research includes two parts: 1. To seek a reasonable control mode to make the unit load-shedding process rise in rpm and minimize the pressure rise in the volute, so as to obtain economic benefits; 2. Degree and the starting angle of the blade, so that the starting process is rapid, axial
