基于继电保护整组试验的智能模拟断路器设计与应用研究OA

In order to solve the problems of low action accuracy and weak interaction ability of traditional analog circuit breakers in power system debugging and training,it proposes a design scheme of intelligent simulated circuit breakers based on multi-source infor-mation fusion.It achieves high-precision simulation of circuit breaker operation characteristics,full-state real-time monitoring and re-mote intelligent control,to meet the high reliability requirements of smart grid regulation simulation and substation operation and main-tenance training.It adopts the STM32H7 microcontroller as the core control unit,integrating Hall current sensors,Angle encoders and wireless communication modules.It optimizes the action timing control algorithm by establishing a mathematical model of the me-chanical characteristics of the circuit breaker.The opening and closing time adjustment range of this intelligent simulated circuit break-er is 10 to 150 ms(with an accuracy of±1 ms),and the action voltage adaptation range is 85%to 110%Un.It supports remote sig-naling,remote measurement,and remote control functions,and can simulate eight typical faults such as failure to operate and misop-eration,providing a high-performance solution for power system simulation training and equipment debugging.It has broad prospects for engineering applications.
