衡水发电厂~#1机组变频干扰停炉分析
【摘要】 详细分析了变频器在电机事故情况下对电源侧产生的谐波干扰以及进而造成FSSS动作停炉的原因 ,提出了在电厂设计和施工中应该注意的问题。
【Abstract】 The coal feeders of Unit 1 in Hengshui Power Plant are powered through thyristor frequency changers. Boiler shutdown occurred while coal feeder motor was in accident. This paper analyzes in detail the fact that the inverter of the frequency changer produces harmonics in power mains while coal feeder driver is in accident, thus causes FSSS to trip the boiler. Some problems have to be cared during design and construction periods of the power plant are pointed out.
