摘　　要：针对传统配电网系统中故障定位方法存在故障定位信息回馈速度较慢的问题,研究了基于SOP拓扑结构的改进配电网系统,减少了系统因自身原因导致的故障。基于数据型乘法器加强了系统全局的故障检出定位的能力,同时增强硬件的抗干扰能力。研究基于MTG定位算法,可以通过对于故障产生原因权重的判断,提高对于定位的精确度。通过仿真试验表明,所设计的硬件抗干扰电路在干扰数据量为10G时抗干扰率能达到97.25%,具有很好的抗干扰能力。Aiming at the problem of slow feedback speed of fault location information in traditional distribution network systems,an improved distribution network system based on SOP topology structure was studied to reduce faults caused by the system itself.The data-driven multiplier enhanced the system’s ability to detect and locate faults globally,while also enhancing the hardware’s anti-interference ability.The research based on MTG localization algorithm can improve the accuracy of localization by judging the weight of the cause of the fault.Simulation experiments have shown that the anti-interference rate of the designed hardware anti-interference circuit can reach 97.25%when the amount of interference data is 10G,indicating good anti-interference ability.
