摘要
水电站运行过程中,为了降低因机组甩负荷使得导叶关闭而引起的管道压力上升值和转速上升值,通常会采取许多措施,其中常用的措施就是控制机组导叶关闭规律。以塔林西水电站为例,用Hammer软件对水电站进行调节保证计算,对于不同的导叶关闭规律,选取最合理有效的导叶关闭方案,并且模拟导水叶开启时尾水管处的压力情况,确定导水叶开启的最短时间。
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.
