摘　　要：为验证励磁系统过励限制与发电机励磁过负荷保护的配合合理性,对田湾核电站二期机组的过励限制与励磁过负荷的参数整定及其配合情况进行了研究,对于定值不配合的问题提出了具体的改进方案,以保证励磁系统过励限制先于励磁绕组过负荷保护动作,为田湾核电及电网的安全稳定运行提供了有力的技术支持。In order to verify the reasonableness of coordination between excitation system overexcitation limit and generator excitation overload protection,the parameter setting and coordination of excitation overexcitation limit and excitation overload protection of Tianwan Nuclear Power Plant Phase II unit were studied,and specific improvement schemes were proposed to solve the problem of fixed value uncoordination,so as to ensure that excitation system overexcitation limit is preceded by excitation windings overload protection action.It provides strong technical support for the safe and stable operation of Tianwan nuclear power plant and power grid.
