Simulation Calculation of Water Hammer in Hydropower Station and Optimization of Guide Vane Closing Rules
During the operation of hydropower station,in order to reduce the increase of pipeline pressure and speed caused by the closure of guide vane due to load rejection,many measures are usually taken,among which the common measure is to control the closure rule of guide vane.Taking Talinxi Hydropower Station as an example,Hammer software is used to carry out the adjustment guarantee calculation of hydropower station,and the most reasonable and effective guide vane closing scheme is selected for different guide vane closing laws.And simulate the pressure at the tail pipe when the water guide blade is opened to determine the shortest opening time of the water guide blade.
