摘　　要：台州发电厂300 MW机组灭磁系统存在灭磁开关弧压低、灭磁电阻能容不足等问题,需进行改造。对新灭磁系统的设备参数进行了分析和计算。更换了灭磁开关,重新配置了灭磁电阻和转子过电压保护,使之满足运行的要求。In order to deal with the problems of the de-excitation system for the 300 MW unit in Taizhou Power Plant including excessively low arc voltage of the de-excitation switch and de-excitation resistance ca- pacity shortage etc, the retrofit is needed. This paper analyzes and calculates the parameters of the new de- excitation system equipments. The de-excitation switch is replaced and the de-excitation resistance and rotor over-voltage protection are re.configured to meet the operation requirements.
