发电机头次并网试验

个人日记

发电机绕组的直流电阻。目的：三相电阻是否平衡。
发电机绕组的极性试验。目的：确定绕组的首尾端。
直流耐压试验。        目的：发电机绕组的绝缘电阻是否合格。
空载升压。            目的：励磁系统和发电机是否正常。
假同期试验。          目的：检测同期并网的回路及条件允许能否同期合闸。
首先新机组的启动试验有很多项目,比方说首次开机时要做"发电
机无励变转速动平衡试验","发电机空载特性试验","发电机带主变递
升加压","发电机短路升流"，"发电机并网试验"等等,有时还要做破坏
性试验,比方"发电机甩负荷试验"等.
发电机并网试验可分别做以下试验：
发电机自动准同期假并试验 （发电机主开关两侧隔刀拉开）
发电机手动准同期假并试验  
发电机自动准同期并网试验 （发电机主开关两侧隔刀合上）
发电机手动准同期并网试验
如果自动同期装置有两套，那么分别都要做假并、真并
 
 
祝愿各位朋友工作顺利、合家幸福
