摘要：
由于技術(shù)與材料的進(jìn)步，現(xiàn)在設(shè)計(jì)的發(fā)電機(jī)組，其故障發(fā)生的幾率大為減少。但是如果一旦發(fā)生，則其可能引起的災(zāi)害將較其他電力設(shè)備的故障更為嚴(yán)重，甚至?xí)чL(zhǎng)期性的停機(jī)損失，尤其是大容量機(jī)組。因此一旦發(fā)覺發(fā)電機(jī)有異常情況時(shí)，就得盡快將其與故障隔離。這也就是本論文所寫到得發(fā)電機(jī)保護(hù)。保護(hù)有效動(dòng)作，使其與部分迅速與故障源隔離。

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
