摘要
Abstract
The bulb turbine generator units have a large unit overcurrent and good operational stability.It can a-chieve dual adjustment of guide vanes and blades by adjusting the operating angle of the impeller blades,and can adapt to relatively large changes in water head.It can also operate stably below a water head of 3 meters.The units of Yinjiang Hydropower Project have the potential to optimize ultra-low head operation.Through comprehensive research on the hydraulic design,electromagnetic scheme,cooling technology,bearing structure,unit stiffness and strength,and fatigue life of the units,it is possible to participate in flood discharge and full-head operation at extremely low heads,obtain greater power generation benefits,and solve the problem of slightly high pressure pulsation under high head and low load conditions.It has important significance and pro-motion value in the application field of bulb tubular units.This paper describes the research process on full-head operation of giant bulb tubular units.关键词
