This paper investigates a new method of diagnosis for faults of hydroelectric generating set. 摘要本文提出了一種水輪發(fā)電機組故障診斷的新方法。
This paper is directed against the reality problem that it is very difficult to measure the critical speed of the shaft system in a large scale hydrogenerator unit in operating. 針對大型水輪發(fā)電機組軸系臨界轉速難以實(shí)際測定的現實(shí)問(wèn)題，從理論分析的角度出發(fā)，抓住水力機組軸系結構的基本特點(diǎn)，提出采用較為簡(jiǎn)單的模擬結構，試驗研究水力機組軸系固有頻率及其振型特征。
