关于1000MW机组电气主接线方案的讨论

Discussion on Main Electrical Connection Project for 1000MW Unit

文献[1]对平顶山第二发电厂4×1000MW机组的4种电气主接线设计方案进行了技术、经济比较后,推荐该工程500kV升压站采用一台半断路器电气主接线方案,但是,启动/备用电源的引接,发电机出口不设置断路器(GCB)等问题有待商榷。

After technique＆ economy comparison of 4 kinds of main electrical connection design projects for 4×1000MW units of Pingdingshan No.2 power plant, reference introduces main electrical connection project for one and a half breaker for 500kv booster station, however, the problems in leading of start-up/standby power source,generator circuit breaker （GCB） not setting on outlet of generator remain to be discussed.
