摘　　要：对甘肃电网出现的发电机低励运行时无功功率大幅度摆动的机理进行了研究，分析了产生这种现象的原因，提出了通过对励磁控制逻辑和控制参数的改进以保证发电机在低励时安全稳定运行的措施。In this paper the reason of large scale oscillation of reactive power in Gansu electric power system is analyzed while the generators is operated in underexcitation condition, and some measures, which includes the improvement of control logic and control parameters, are put forward to ensure the secure and stable operation of generators in case of underexcitation.
