基于边缘计算的配电网低电压监测方法

Low Voltage Monitoring Method of Distribution Network Based on Edge Calculation

由于以往配电网电压监测方法在应用过程中无法确保监测数据的同时性,无法对配电网运行参数变化情况及时反馈,易造成监测精度低的现象。针对这一问题,引入边缘计算,开展对配电网低电压监测方法的优化设计研究。通过配电网低电压边缘设备监测数据采集,基于相关系数的配电网低电压台区识别,基于边缘计算确定低电压电表节点连接关系、基于监测结果的异常电压表拓扑节点定位,提出一种全新的监测方法。通过对比实验的方式证明,新的监测方法监测结果的皮尔逊系数更高,监测精准度与以往配电网电压监测方法相比得到了明显提升。

Because the previous distribution network voltage monitoring methods can not ensure the simultaneity of monitoring data in the application process,and can not feed back the changes of distribution network operation parameters in time,resulting in low monitoring accuracy.To solve this problem,edge calculation is introduced to study the optimal design of low voltage monitoring method in distribution network.A new monitoring method is proposed through the monitoring data collection of low-voltage edge equipment of distribution network,the identification of low-voltage station area of distribution network based on correlation coefficient,the determination of low-voltage meter node connection relationship based on edge calculation,and the topology node location of abnormal voltmeter based on monitoring results.Through comparative experiments,it is proved that the Pearson coefficient of the monitoring results of the new monitoring method is higher,and the monitoring accuracy is significantly improved compared with the previous distribution network voltage monitoring methods.
