摘要
配电线路故障主要受设备质量、平均负载率、运行环境三方面因素影响,同一变电站出线、同一时期新投/改建的线路或同一区域内的配电线路发生故障的概率有相关关系。提出了基于Apriori算法的配电线路故障关联分析方法,供电企业可使用配电线路故障历史数据作为样本,利用该方法分析所辖电网内配电线路发生故障的相关性,针对性安排配电线路特殊巡视工作。某条线路发生故障后对其他发生故障可能性较大的线路提前采取措施,避免故障发生。
Distribution line fault is mainly affected by three factors:equipment quality,average load rate and operation environment.The probability of line fault in the same substation,new lines/reconstructed lines in the same period or lines in the same area is related.A method of fault correlation analysis for distribution lines based on Apriori algorithm is proposed.Power supply enterprises can use the historical data of distribution line fault as samples,this method can be used to analyze the correlation of distribution line fault in their own power grid,and arrange special patrol work of distribution line.When a line fails,measures can be taken in advance for other lines with high probability of failure to avoid failure.
