摘要:
由于技术与材料的进步,现在设计的发电机组,其故障发生的几率大为减少。但是如果一旦发生,则其可能引起的灾害将较其他电力设备的故障更为严重,甚至会带长期性的停机损失,尤其是大容量机组。因此一旦发觉发电机有异常情况时,就得尽快将其与故障隔离。这也就是本论文所写到得发电机保护。保护有效动作,使其与部分迅速与故障源隔离。
Abstract
When carries on the disposition to the generator protection, should to below protect gives the enough value: Double densified differential motion protections, stator earth protection, negative sequence overflow protection, overvoltage protection, arrow magnetism arrow step protection and so on. At the same time, should consider the disposition low frequency, on the electricity, opens the engine off protection by mistake. In the protection movement characteristic aspect should consider and unit's ability and the match, as far as possible uses the inverse time lag characteristic in the superheat protection, the fast operating time should be as far as possible quick.
Key words: Relaying protecting The power set
The generator protection
