小电流接地故障区段定位软件的设计与开发
|
摘要
针对暂态录波型故障指示器的推广应用,基于暂态零模电流波形相似度算法,提出了简易配电网线路模型,开发了小电流接地故障区段定位软件。该软件以VS.NET为开发平台,具有图形化建模、设备信息与参数查询、故障定位分析等功能。小电流接地故障区段定位的具体过程是根据电网线路模型形成树状网络拓扑,从拓扑根节点开始向下对比相邻零模电流波形的相似度,逐一排查故障区段。最后根据实际使用情况,给出了影响区段定位精度的因素及其解决措施,并以实际故障波形验证了此软件对故障区段定位的有效性。
Aiming at the wide application of transient recorder type fault indicator,a simple distribution model is proposed based on transient zero-mode current waveform similarity algorithm,and a small current grounding fault location software is developed.The software takes VS.NET as the development platform,with a graphical modeling capabilities,device information and parameter query,fault location analysis and other functions.The specific process of locating the fault section of small current grounding is to form a tree network topology according to the network line model, and to compare the similarity of the adjacent zero-mode current waveforms downward from the root node of the topology, so as to check the fault section one by one.Finally,according to the actual use situation,the factors influence the positioning accuracy and the solution are given.And the software validates the validity of the fault zone location with the actual fault waveform.
