抽水蓄能机组单导叶控制不同步故障分析与处理

摘要

以广州蓄能水电厂为例,介绍了单导叶控制调速器导叶控制环的构成.针对导叶不同步跳闸故障进行了细致分析和推理,定位了故障点；通过解体检查找到了故障的具体原因,并实施了相应的处理和预防措施.%The control loop of independent wicket gate control governor system in Guangzhou Pumped-storage Power Station is introduced. For solving the fault caused by asynchronous opening of the wicket gates, the detailed analysis is conducted to locate the failure position, and the real failure reason is found by disassembling. The appropriate treatment and preventive measures are also introduced herein.
