一种关口电能表运行误差评估方法及系统
摘要：
本发明公开了一种关口电能表运行误差评估方法，其特征在于，所述方法包括：获取关口电能表在至少两个检测负荷点数据对应的误差数据；采集所述关口电能表在预设运行时间段内的运行负荷点数据并绘制运行负荷点数据曲线；获取所述运行负荷数据曲线上每隔预定时间长度处的运行负荷点数据；分别将每个运行负荷点数据与每个检测负荷点数据进行差值计算，选取与每个运行负荷点数据差值的绝对值最小的两个检测负荷点数据；建立所述关口电能表运行拟合误差计算模型，并分别计算每个运行负荷点数据对应的运行拟合误差；以及根据上述每个运行负荷点数据对应的运行拟合误差，采用加权平均值法计算所述关口电能表在预设运行时间段内的运行误差。

The invention discloses a method for evaluating the operation error of a gateway energy meter. The method comprises the following steps: acquiring the error data corresponding to at least two pieces of detection load point data of the gateway energy meter; collecting the operation load point data of the gateway energy meter in preset operation time and drawing an operation load point data curve; acquiring the operation load point data on the operation load data curve at every predetermined time length; performing deviation calculation on each piece of operation load point data and each piece of detection load point data, and selecting two pieces of detection load point data with a minimum absolute value of a difference value with each piece of operation load point data; creating a gateway energy meter operation fitting error calculation model, and calculating the operation fitting error corresponding to each piece of operation load point data; and calculating the operation error of the gateway energy meter in the preset operation time by using a weighted average method according to the operation fitting error corresponding to each piece of operation load point data.
