| 摘 要： | 125MW发电机机组给粉变频器自身内部参数设置存在缺陷与分散控制系统DCS中给粉控制部分设计配合不合理,当电网系统受到冲击,厂用电源电压波动时,多次发生给粉变频器跳闸,引发锅炉MFT动作,机组跳闸事故。改造后的控制系统稳定性大大的提高,避免发电机组跳闸非计划停机。

| Abstract: | 125 MW generator unit to powder inverter parameter Settings inside defects and decentralized control system DCS to powder control part design fit is not reasonable,when power grid system affected,factory with the power supply voltage fluctuation,it has happened so many times to powder converter trip,causing boiler MFT action,unit trip accident.After the transformation of the control system greatly improve the stability,avoid generating set trip unscheduled shutdown. |
