| Abstract: | Three kinds of typical partial discharge signals of generator stator windings are studied, and the discharge pulse waveform and frequency spectrum are obtained. A LabVIEW-based detection system for partial discharge of generator stator windings is designed. Aiming at the characteristics of partial discharge signals, the anti-disturbing techniques of digital filter and pulse-delay discrimination are designed. These techniques are the key to the realization of the detection system for generator stator windings, and to the accurate detection of the three kinds of typical partial discharge signals. |
