摘　　要：开发了以可编程控制器为核心的故障模拟控制系统。该系统由PLC可编程控制器、故障点选择器、故障形态选择器、合闸角控制器和故障开关组成。能够在实验室中模拟产生各种各样的电力系统故障 ,能够对故障预录波时间、故障持续时间、故障位置、故障形态、转换性故障转换时间、转换性故障重叠时间等故障参数进行精确调节。同时还可以模拟保护对线路的跳闸、重合闸等操作。A control system of fault simulation is developed based on PLC. The system consists of PLC, fault position controller, fault mode controller, fault angle controller and fault switch.By this system, all faults of power system can be produced at lab.Fault parameters, such as pre fault recorder time, continuous time, position, mode, overlap and interval time, can be precisely adjusted. And also, trip and auto close operation of relay can be simulated.
