摘　　要：提出了一种并网电厂发电机出口侧大电流互感器现场误差智能校验系统方案及其校验方法,解决了发电机出口侧大电流互感器按规程现场校验电源容量无法实现、电源三相不平衡、设备容量要求大以及体积重量大的难题,可实现发电机出口大电流互感器误差的准确、智能、高效的测量。An intelligent on-site error calibration system and method for large current transformers at outlet sides of generators in grid power plants are presented in this paper. The system solves the problems of unachieved power supply capacity, unbalanced three phases of power supply, over-capacity required, large volume and big weight of equipment according to the on- site calibration regulations of large current transformers at outlet sides of generators. So accurate, intelligent and efficient error meas urement oflarge current transformers can be realized.
