摘　　要：目前,供电所计量异常数据采集终端的抗干扰方法在面对脉冲或窄带干扰时,很容易受到影响,尤其是存在混合干扰情况下,传统方法有很大的局限性。为了解决上述问题,通过衰减补偿分析,提出了一种新的供电所计量异常数据采集终端抗干扰分析方法。建立衰减补偿拓扑结构,计算电力线路中父节点电流;使用波导补偿方式实现对光纤衰减环境的补偿;通过启发因素确定节点与节点之间的信息素浓度;利用方向因子和蚁群算法建立异常数据采集终端抗干扰体系;由异常数据采集终端中的信号采集装置完成异常数据的监测与录入,实现抗干扰分析。实验结果表明,本文方法能够通过混合干扰分析降低损耗,抑制99%以上的干扰信息,提高异常数据的抗干扰能力。The current anti-jamming method for abnormal data acquisition terminal metering in power supply stations is easily affected in face of pulse or narrowband interference.Especially in the presence of mixed interference,traditional methods have great limitations.In order to solve the problems,a new anti-jamming analysis method of the abnormal data acquisition terminal measured by the power supply station is proposed through attenuation compensation analysis.This paper establishs the attenuation compensation topology,calculates the current of the parent node in the power line,uses the waveguide compensation method to realize the compensation of the optical fiber attenuation environment,determines the pheromone concentration between nodes through the heuristic factor,and uses the direction factor and the ant colony algorithm to establish the anti-jamming system of abnomal data acquisition terminal.The signal acquisition device in the data acquisition terminal completes the monitoring and input of abnormal data,and realizes anti-interference analysis.The experimental results show that the proposed method can reduce the loss through mixed interference analysis,prevent more than 99%of the interference information,and improve the anti-interference ability of abnormal data.
