摘　　要：发电机的失磁保护必须在励磁调节器的低励限制之后动作。为防止失磁保护误动作,相关规程均明确要求失磁保护和低励限制的整定计算必须满足这个配合条件。现就失磁保护和低励限制的整定原则和它们之间的配合方法进行具体论述,并以实例予以详细说明。Field failure protection of generator has to operate after low excitation limit. To prevent malfunction of field failure protection, the setting match between field failure and low exciration limit should conform with this requirement that related protocol states. The setting principle and match method is discussed and explained by example.

关 键 词：失磁保护 低励限制 整定配合 防误动
