침대오강계수전엄5호궤조상도파도편대문제，이용궤조은정성재선감측계통적록파、계산、분석공능，실시궤조적변전속、변려자、변부하시험，채용다충방법진행분석，득출발전궤전자질량불평형시도치5호궤조파도편대적주요원인적결론。
Aiming to large numerical value of upper guide throw for Wuqiangxi Hydropower Plant NO. 5 unit, several stability tests including variable speed test, variable excitation test and variable load test are independently designed and implemented by making use of the recording, calculation, analysis function of hydropower unit stability online monitoring system by a variety of methods. Through the above measures, the conclusion are drawn that the generator rotor mass imbalance is the main reason of large numerical value of upper guide throw for NO. 5 unit.
