针对五强溪水电厂5号机组上导摆度偏大问题

利用机组稳定性在线监测系统的录波、计算、分析功能

实施机组的变转速、变励磁、变负荷试验

采用多种方法进行分析

得出发电机转子质量不平衡是导致5号机组摆度偏大的主要原因的结论。

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.
