摘要
介绍了大型燃气轮发电机的特点及其对定子接地保护的影响,提出了完整的燃气轮发电机定子单相接地保护方案,该方案弥补了以往大型燃气轮发电机定子接地保护方案的不足,使之在国内外多台390MW级大型燃气轮发电机组得到了广泛的应用,取得了较好的效果。
The characteristics of large gas-steam combined-cycle generator and its influence on stator grounding fault protection were introduced. A complete large gas-steam combined-cycle generator stator single phase grounding fault protection scheme was proposed. In the scheme,the shortcoming of previous large gassteam combined-cycle generator stator grounding fault protection scheme was overcome. The scheme was applied widely on many domestic and abroad 390 MW level large gas-steam combined-cycle generator units,and favorable effects were obtained.
