Research On Power Network Topology Identification Method Based On Current Characteristic Signal

针对现有电网拓扑识别方法存在的故障排查率低、周期长、成本高和无法得到实时准确的线路拓扑关系。以电流信号为特征信号,对信号进行分析和多次验证。在不影响载波通讯的情况下,通过现场终端完成用电线路的自动拓扑识别,确保识别的准确率。经过实验验证,基于电流信号的识别方法稳定可靠,识别率较高,一定程度上减小人力的大量投入。

In view of the existing grid fault problems of topology identification method screening rate is low,the cycle time is long,high cost,and can't get the real-time accurate circuit topology relationship.Based on the characteristic signal of current signal,the signal analysis and validation for many times.Under the condition of without affecting the carrier communication,through the terminal to complete electricity line automatic topology identification,ensure the accuracy of recognition.After experimental verification,the recognition method based on the current signal is stable and reliable,the recognition rate is higher,to a certain extent reduce the large amount of manpower.
