摘要
发电机定转子的变形会破坏原机组的磁路线,有可能形成磁振动,增大机组的振动,恶化机组的运行工况。通过现场在线监测的实验数据建立了一种定转子变形的评价方法,并在实际电站运行中得到了初步验证。
Distortion of stator or rotor would destroy the magnetic circuit of generator and causing magnetic oscillation, enhancing the oscillation of generator and deteriorating the operating condition of generator. This paper presents one assessment method of stator rotor distortion by the experimental data of site online monitoring, which is validated preliminarily at one power station.
