针对目前我国电网对智能电表到期更换和批次抽检轮换等运行维护中存在的不足,提出一种基于计量自动化系统采集数据的智能电表运行误差估算的轮换策略。首先,以台区为单位,建立智能电表运行误差估算模型;其次,针对估算模型病态性情况,采用正则化方法求解;最后,根据多个时间窗滚动计算和综合评价机制筛选出轮换的智能电表用于现场校验。通过实际电网算例验证了所提策略的有效性。
In response to the deficiencies in the operation and maintenance of China’s power grid regarding the replacement of expired smart meters and batch sampling rotation
a rotation strategy for estimating the operation error of smart meters based on data collected by the metering automation system was proposed. Firstly
a smart meter operation error estimation model was established on a per-transformer-area basis. Secondly
a regularization method was adopted to solve the ill-conditioned situation of the estimation model. Finally
based on rolling calculations over multiple time windows and a comprehensive evaluation mechanism
smart meters for rotation were selected for field verification. The effectiveness of the proposed strategy was verified through practical examples in the power grid.
