主变压器倒送电前快切系统动态调试的新方法

New method of dynamic debuggiong of fast switching over system before reverse power transmission of main transformer

针对调度不建议进行主变压器倒送电试验的情况,设计了一种新的快切调试方法。该方法可实现机组启动前厂用电动态切换,提高机组正常投运后快切系统动态切换的准确性。

Aiming at the suggestion of the dispatch department,in which the reverse power transmission test of the main transformer was not recommended,a new fast switching over system debugging method was designed.By using this method,the dynamic switching over of auxiliary power before the unit starting can be realized;and the correctness of the dynamic switching of the fast switching over system after the unit was put into operation had been increased.
