Metering abnormal data identification method and system

The invention relates to a metering abnormal data identification method and system, and the method comprises the steps of collecting data, and obtaining a focus transformer area according to the electric quantity difference between the transformer area total meter power supply quantity and the transformer area power sale quantity; obtaining users with large electric quantity jump through the power utilization data of the user sub-meters; and identifying suspected abnormal data through an electric quantity change relationship between the transformer area general table and the user sub-tables. On the basis of fully utilizing the existing data, the working efficiency of abnormal data identification and data governance in the metering automation system is improved, the abnormal data in the metering automation system can be rapidly identified, and a basis is provided for data check and governance work. 本发明涉及一种计量异常数据识别方法和系统，采集数据，根据台区总表供电量与台区售电量的电量差获得重点关注台区；通过用户分表的用电数据，获得电量跳变大的用户；通过台区总表与用户分表之间的电量变动关系识别疑似异常数据。本发明在充分利
