摘　　要：为提高大型发电机组运行的可靠性和稳定性,在进行发变组保护整定计算时,必须考虑与励磁调节器限制定值的匹配,即发电机失磁保护定值与励磁调节器欠励限制参数之间的配合,以及发电机过励磁保护定值与励磁调节器V/Hz限制参数之间的配合,最后是发电机定子过电流保护与励磁调节器定子电流限制之间的配合,否则励磁系统一旦出现异常,可能会导致发变组保护动作于跳闸,造成发电厂非停事故。In order to improve reliability and stability in large operation generator,it should consider to parameter and fixed value matching between generator protection and excitation adjustor.The matching between settings on generator loss of field protection and excitation regulator parameter restrict on low exciting,as well as matching between settings on generator over exciting and excitation regulator parameter restrict on V/Hz,eventually matching between settings on generator stator over current protection and excitation regulator parameter restrict on stator current.Otherwise,as the excitation system appear abnormally,it maybe act in generator protection and cause accident power plant.
