摘要
某在建核电项目以岭澳二期为依托,同样采用百万千瓦汽轮发电机组技术,但其设备选型存在诸多差异,发电机整组启动面临新的困难。调试人员通过深入分析,解决了励磁变接入时机、定子接地保护验证窗口、主变差动校验方法等问题,并提出了一种新的发电机整组优化方案,在该项目1~4号发电机组实践的基础上,最终形成本文,供我国核电百万千瓦级发电机组整组启动参考。
A nuclear power project taking Ling＇ao phase II as reference, applied the same 1000MWgenerator technology, but chose some different equipment. Through in-depth technical analysis, testpersonnel solved many problems such as when the excitation transformer joined in, how to do thestator earth fault and main-transformer differential protection tests, and proposed a new start-upcommissioning method, this paper was written on the basis of the practice of units 1-4, which is areference for the whole set of the 1000MW half speed generator.
