摘　　要：以某海上石油钻采平台发电机励磁控制系统为例,针对一起发电机并网运行时吸收电网无功功率故障,在对发电机励磁系统、无功功率分配系统和电源管理系统的工作原理进行分析的基础上,进一步分析了故障原因及引起无功功率分配故障的机理,更换造成该故障的多功能测量装置,恢复电网系统的稳定运行,供发电机运维人员或电网管理人员参考。Taking the generator excitation control system of an offshore oil drilling platform as an example,aiming at the fault of absorbing grid reactive power when a generator is connected to the grid,the working principles of generator excitation system,reactive power distribution system and power management system are analyzed.On this basis,the cause of the fault and the mechanism of the reactive power distribution fault are further analyzed.The multi-function measuring device that caused the fault is replaced and the stable operation of the power grid system is restored,which can be used by generator operation and maintenance personnel or power grid management personnel for reference.
