摘　　要：文章针对不同厂家生产的单相智能电能表在线使用时计量准确性问题,在相同实际负载条件下进行相关试验。通过一种新型的高精度单相安装式标准电能表模拟用户实际使用情况,采用多种不同功率的负载对单相智能电能表在实际运行中的基本误差、电量走字误差进行测试。与实验室参比条件下检定装置测试的数据进行比对,验证分析单相智能电能表在参比条件下检定装置测试数据的可靠性和一致性。通过实验数据分析表明,该方法可以真实反映单相智能电能表在实际使用中基本误差和电量误差的情况,可以作为单相智能电能表在线检测的一种新的方法。Aiming at the measurement accuracy of single-phase smart meter produced by different manufacturers when it is used online,this paper carries out relevant tests under the same actual load conditions.Through a novel type of high precision single-phase installation type standard electricity meter,simulating the actual usage of users,a variety of different power load is used to test the basic error and electric quantity running error of single-phase smart meter in actual operation.Then,this paper compares the test data of the verification device under the reference condition in the laboratory to verify the reliability and consistency of the test data of the verification device under the reference condition.The analysis of experimental data shows that this method can truly reflect the basic error and electric quantity error of the single-phase smart meter in actual use,and it can be used as a novel method for online detection of the single-phase smart meter.
