| 摘 要： | 本文探讨了一种利用发电机定子匝间短路时产生的高频瞬时电压和电流进行故障检测的新方法,该方法通过对发电机定子匝间短路时因内部对称性被破坏而产生的高频瞬时电流和电压进行小波分析,找出判定故障的特征.通过仿真模拟与研究,证明发电机定子匝间短路时的高频瞬时电流是可以做为故障特征来判定的.

| Abstract: | A new method is discussed to detect and predicate the turn-to-turn armature fault of the generator in this paper. By means of a wavelet analysis method, the dynamic voltage and current resulted from the unsymmetric fault of the generator is analyzed. Simulation research shows that the high-frequency current can be regarded as a characteristic of the turn-to-turn armature fault. |
