摘　　要：用电负荷坏数据会对电力供电产生很大的破坏性,为了提高对电力负荷坏数据的检测能力,设计基于最大流算法的电力负荷坏数据辨识系统。硬件主要包括采集器、处理器、信号识别器三部分,采集器在高压电池侧边需要放置微控制单元,处理器将波形数据转换为数字信息实现控制。信息识别器的连接结构为阅读芯片与单片机的输入端口互相连接,单片机的输出端口与通信状态显示屏相互连接,载波发生器与调制器相互连接。利用最大流算法建立拓扑模型,在电力系统网络流中,采用中心性指标完成对点到边、边到点、点到点、边到边之间的电力数据划分,利用最大流算法对坏数据完成辨识。实验结果表明,所设计系统可以确保电网受到攻击后剩余流量高于95%,辨识准确率高于90%。In order to improve the detection ability of power load bad data,a power load bad data identification system based on maximum flow algorithm is designed.The hardware mainly includes the collector,processor and signal recognizer.The collector needs to place a micro control unit at the side of the high⁃voltage battery,and the processor converts waveform data into digital information to realize control.The connection structure of the information recognizer is that the reading chip is connected with the input port of the single chip microcomputer,the output port of the single chip microcomputer is connected with the communication status display screen,and the carrier generator is connected with the modulator.The maximum flow algorithm is used to establish the topology model.In the power system network flow,the central index is used to divide the power data from point to edge,edge to point,point to point and edge to edge,and the maximum flow algorithm is used to identify the bad data.The experimental results show that the designed system can ensure that the residual flow is higher than 95%and the identification accuracy is higher than 90%.
