摘　　要：首先介绍了发电机组主流涉网保护与励磁调节器辅助限制,并基于实时数字仿真系统构建了仿真测试平台,开展发电机组涉网保护与励磁控制的协调配和研究。在此基础上提出了过激磁保护与伏赫兹限制、失磁保护与低励限制、定子过负荷保护与定子电流限制、转子过负荷保护与过励限制的配合性能评估指标与测试方法。仿真算例验证了方法的有效性。The grid - related protection of generating units and the auxiliary limiters of automatic voltage regulator are introduced firstly in this paper. Based on real time digital simulator,the simulation test platform is constructed for re- searching the mating performance between the grid-related protection and excitation control of generator. On this ba- sis, this paper proposes the evaluation indexes and measurement methods of excitation protection and voltage/fre- quency limit,loss of excitation protection and under excitation limit,over load protection of the stator and stator cur- rent limit, over load protection of the rotor and over excitation limit. Simulation results show the effectiveness of the proposed method.
