The Cause and Preventing of the Excitation System's Electromagnetic Interference in Power Plant

In the course of the earlier production of #7 Power Generation Unit in Guangzhou Hengyun Power Plant, because of the electromagnetic interference the excitation system regularly gives an improper alarm. This paper primarily analyses the cause of electromagnetic interference and brings forward corresponding preventive measure and attendant proceeding, so that at the production process improper alarms because of the electromagnetic interference may be effectively decreased and the reliability of electronic equipment may be improved.
