为满足能耗监管的目的，有大量电表支撑的分项计量平台在中国商业建筑中得到推广和使用，电耗数据可用来进行能耗分析。然而，由于环境电磁干扰以及其他电表故障，电耗数据的质量受到质疑。提出了一种基于相关系数和数据光滑度的方法，来分别诊断等比例偏离故障和环境干扰故障。对上海某建筑的测试发现，当故障电表个数较少时，该方法可获得较高的准确率。考虑到多个电表同时发生故障的可能性较小，该方法可应用于工程实际。
為滿足能耗鑑管的目的，有大量電錶支撐的分項計量平檯在中國商業建築中得到推廣和使用，電耗數據可用來進行能耗分析。然而，由于環境電磁榦擾以及其他電錶故障，電耗數據的質量受到質疑。提齣瞭一種基于相關繫數和數據光滑度的方法，來分彆診斷等比例偏離故障和環境榦擾故障。對上海某建築的測試髮現，噹故障電錶箇數較少時，該方法可穫得較高的準確率。攷慮到多箇電錶同時髮生故障的可能性較小，該方法可應用于工程實際。

Due to the increasing power metering devices in commercial buildings in China for energy monitoring, significant amount of electricity consumption data are now available for analysis. However, because of environmental electromagnetic disturbance and various faults that could occur with electricity meters, quality of the collected data is a question. A methodology based on correlation coefficient and data smoothness is proposed to detect and recover the proportional deviation faults and environmental disturbance faults, respectively. Testing this methodology with data collected from a real building in Shanghai, it is found that a high accuracy can be achieved given a small number of faulty sub-meters. Considering the low possibility of simultaneous multiple faults, this method is practical in real situations.
