基于多策略融合的室分小区隐性故障发现

Hidden Fault Discovery of Indoor Distribution System Cell Based on Multi-Strategy Fusion

当前室分小区隐性故障排查主要依赖人工巡检,存在现场测试排查周期长、对人工经验依赖严重、用户感知差等问题。提出基于多策略融合的室分小区隐性故障发现方法,利用8种KPI指标,使用Prophet算法确定动态阈值,通过研究指标重要性调整策略和修正非连续异常值策略相融合的多策略故障诊断,实现对室分隐性故障的快速定位。根据上述方法构建室分健康监控体系,辅助运维人员快速定位与修复隐性故障,提升用户感知。

At present,the hidden fault troubleshooting of indoor distribution system cell mainly relies on manual inspection,and there are problems such as long on-site test and troubleshooting cycle,heavy dependence on manual experience,and poor user perception.A hidden fault detection method based on Multi Strategy fusion is proposed.It uses Prophet algorithm with 8 KPI indicators to determine the dynamic threshold.By studying the multi-strategy fault diagnosis with the index importance adjustment strategy and the non-continuous outlier correction strategy,it can quickly locate the hidden faults of indoor distribution system.According to the above method,an indoor signal distribution health monitoring system is constructed to quickly assist in locating and repairing hidden faults,and improve user perception.
