电能表典型采样电路的窃电及差错电量分析

Analysis of Electricity Stealing and Error in Typical Sampling Circuit of Electric Energy Meters

电能表作为常见的电能计量装置,一旦发生故障,必将影响用户用电量的统计,使实际用电量无法得到正确计量,产生电量差错。如何提高电能表的准确性,做好窃电与差错电分析,避免供电企业与用电客户发生矛盾冲突是电力行业目前发展中面临的重要问题。文章对差错电量造成的原因进行了介绍,以某供电局电量差错故障为例,应用计量自动化技术对其差错电量进行了分析计算,取得了较好效果。

As a common energy metering device,if an energy meter malfunctions,it will inevitably affect the statistics of user electricity consumption,making it impossible to accurately measure actual electricity consumption,resulting in electricity errors.How to improve the accuracy of the energy meter,do a good job in analyzing electricity theft and errors,and avoid conflicts between power supply enterprises and electricity customers is an important issue facing the current development of the power industry.The article introduces the causes of incorrect electricity consumption,and takes a case of electricity consumption error in a certain power supply bureau as an example to analyze and calculate the incorrect electricity consumption using measurement automation technology,achieving good results.
