摘要
对恒运热电(C)厂7号汽轮发电机组的励磁系统由于220V直流电源误接入24V直流电源回路而受到干扰,造成两个通道间频繁互相切换的事故现象进行分析和处理,并且针对励磁系统原设计不合理造成抗干扰能力差的问题实行两项抗干扰改进措施,改进后的励磁系统运行稳定。
The misconnection between 220 V DC power supply and 24 V DC power source loop caused disturbance on the excitation system of No. 7 steam turbo-unit in Hengyun Cogeneration Power Plant C, and led to frequent mutual switching between the two channels of the system. The fault was analyzed and solved. Two anti-jamming measures were also taken to improve the poor anti-interference ability of the irrationally designed excitation system, causing the system to operate stably.
