摘　　要：为减少抽水蓄能电站机组寿命损耗,综合分析了抽水蓄能电站一管多机甩负荷试验的目的,并通过山东沂蒙抽水蓄能电站同一流道2台机组单机和双机同时甩负荷的试验数据与计算结果的对比分析,证明极端工况下的计算结果是可信的。建议在完成多机同时甩50%、75%额定负荷的试验后,当计算结果与真机试验数据高度相似时,可取消一管多机同时甩100%额定负荷试验。In order to reduce the life loss of units in pumped-storage power station,the purposes of load rejection test of one-pipe multiple-units system of pumped-storage power station are comprehensively analyzed,and the test data of load rejections of two units in one-pipe in Shandong Yimeng Pumped-storage Station are compared with the calculation results,including single unit s load rejection and two unit s simultaneous load rejection.The comparison proves that the calculation results under extreme operation conditions are credible.Therefore,it is suggested that,if the calculation results of the simultaneous load rejection tests of one-pipe multiple-units under 50%and 75%rated load are highly consistent with actual load rejection test data respectively,the simultaneous 100%rated load rejection test of one-pipe multiple-units can be cancelled.
