摘　　要：电能计量表在使用过程中出现故障,会导致电力消耗情况记录精准度降低。为了避免该现象的发生,提出基于直接数字控制(direct digital control,DDC)的电能计量装置现场检验方法。依据电能计量装置相关特点,处理电能计量装置现场数据。结合DDC技术,设计配变关口现场检验数据取证过程,通过前期准备、误差值确定和误差处理完成配变关口现场检验。设计互感器负荷现场检验数据取证过程,完成互感器负荷现场检验。在DDC支持下,设计信息隐藏模型。经实验验证:随着检验时间不断增加,无故障状态下所提方法检验精准度高于85%,在互感器故障情况下所提方法检验精准度最高为88%。In the process of using the electric energy meter,a fault may reduce the accuracy of power consumption record.In order to avoid this phenomenon,a field inspection method of electric energy metering device based on direct digital control(DDC)is proposed.According to the characteristics of electric energy metering device,the field data of electric energy metering device are processed.Combined with DDC technology,the data forensics process of distribution transformer gateway field inspection is designed,and the distribution transformer gateway field inspection is completed through preliminary preparation,error value determination and error processing.We design the data forensics process of field inspection of transformer load,and complete the field inspection of transformer load.Under the support of DDC,the information hiding model is designed.The experimental results show that with the increase of test time,the test accuracy of the proposed method is higher than 85%under no fault condition,and the highest test accuracy of the proposed method is 88%under transformer fault condition.
