1 前言葛洲坝电厂发电机主励装置采用的是交流侧串联自复励方式,同时,考虑安全可靠地向系统供电,还装设了备励装置。以二江电厂为例,7台发电机共配备了2套备励装置;这两套备励装置分别布置在2F 和7F 主励机盘旁,其中布置在2F 主励机盘旁的备励装置编号为1#备励,相应的布置在5F 主励机盘旁的编号为2#备励,主、备励装置接
1 Preface Gezhouba power plant generator main excitation device is used in the AC side of the series self-recovery mode, at the same time, consider the safe and reliable power supply to the system, but also installed a backup device. Taking the Erjiang Power Plant as an example, two generator sets are equipped with two sets of excitation devices. The two sets of excitation devices are respectively arranged beside the main excitation plates 2F and 7F. The two excitation devices are arranged beside the 2F main excitation plate Device # 1 spare excitation, the corresponding arrangement in the 5F main excitation disk next to the No. 2 spare excitation, the main and backup excitation device
