Spatiotemporal dynamic load monitoring method of charging pile based on steady state characteristics

目前提出的充电桩时空动态负荷监测方法监测耗时过长,导致监测误差率较高。为解决上述问题,基于稳态特征研究一种新的充电桩时空动态负荷监测方法。根据充电桩的时间和空间信息顺序进行排列,对充电桩时空动态负荷数据进行稳态特征识别提取,主要从电力负荷的电流特征、电压特征、功率特征等方面来进行稳态特征识别提取。根据充电桩的位置分布对充电桩的电力负荷情况进行采集,根据数据分析检测结果,构建负荷数据二维矩阵以及负荷监测模型,完成充电桩时空动态负荷的监测。实验结果表明,基于稳态特征的充电桩时空动态负荷监测方法能够在保证高监测效率的同时,有效降低监测误差率。

At present,the time-consuming monitoring method of charging pile time-space dynamic load monitoring is too long,which leads to high monitoring error rate.In order to solve the above problems,based on the steady-state characteristics,a new spatiotemporal dynamic load monitoring method is studied.According to the order of time and space information of charging piles,the steady-state feature recognition and extraction are carried out for the spatiotemporal dynamic load data of charging piles,mainly from the current feature,voltage feature,power feature and other aspects of power load.According to the location distribution of the charging pile,the power load of the charging pile is collected.According to the data analysis and detection results,the two-dimensional matrix of the load data and the load monitoring model are constructed to complete the spatiotemporal dynamic load monitoring of the charging pile.The experimental results show that the space-time dynamic load monitoring method based on steadystate characteristics can ensure high monitoring efficiency and effectively reduce the monitoring error rate.
