摘要(Abstract)：

发变组转子绕组过负荷保护与励磁调节器过励限制保护正确的动作配合关系,应该是励磁调节器过励限制保护先于发变组转子绕组过负荷保护动作。通过对四方CSC-300F发变组转子绕组过负荷保护与Unitrol 5000励磁调节器过励磁限制动作值与动作时间的计算与分析,指出过励磁限制保护设计上存在的缺陷并提出解决方法。
The over-excitation limitation protection of excitation regulator should occur before the overload protection of generator-transformer unit rotor winding in the correct action cooperation between the overload protection and over-excitation limitation.Through the calculation and analysis of the action values and time of the overload protection of CSC-300F generator-transformer unit rotor winding and the over-excitation limitation of Unitrol 5000 excitation regulator,this paper puts forward the defects in the design of over-excitation limitation protection as well as the solutions.
