摘要
分析了发电机突加压的原因和造成的危害,并根据突加压的特点提出了完整的保护方案,该方案能适应各种方式的主接线,对发电机未加励磁时误合闸,发电机主断路器发生单相(两相)闪络,断路器单相(两相)拒分和发电机以较大频率差非同期并网进行主动识别,保护可靠性高,具有较高的实用价值。
The causes and harms of inadvertent energizing is analysed and a whole scheme is presented on the fault characteristics, which adapts to different primary connections. It can distinguish the inadvertent energizing of unexcited generator, single or double phase flashover of breakers and differential - frequency asynchronous parallelizing. It also have great reliability and great practical merit.
