提出并研制了一种新型电力系统暂态故障模拟再现系统。该系统通过将系统发生故障时故障录波器录下的数据转换为符合IEEE的COMTRADE格式文件,经数据处理软件进行分析后由电脑并口送入多功能继电保护测试仪,最终由测试仪还原成故障时的PT、CT二次侧电压、电流信号。该系统对继电保护装置参数整定、事故原因查找及分析等有辅助作用。-proposed and developed a new type of power system transient fault simulation and reconstruction system.IEEECOMTRADE. The system of relay device parameter setting, the cause of the accident investigation and analysis of a supporting role.
