摘　　要：目前,国内尚无直流计量检测系统的行业标准,直流计量检测系统由于缺乏相关的指标导致检测结果的准确性无法保证,通过分析直流电能计量检测系统的指标参数和关键技术,对电能测量方式、纹波影响下直流电能计量检测系统的计量特性、直流电能表检测系统的量值传递体系与校准系统进行研究,提出相应的准确性保证试验方法,为后期建立完善的直流电能表检定方案和准确性保证体系打下基础。At present,China has no industrial standards for the DC metering detection system.Lack of relevant indicators for the DC metering detection system makes accuracy of the test results unguaranteed.Through analyzing the DC energy metering detection systems’index parameters and key technologies,its metrological characteristics affected by the energy measurement mode and ripple wave,measurement value transfer system and calibration system,a corresponding accuracy-assured test method was provided to lay the foundation for establishing a complete DC energy meter verification scheme and the accuracy assurance system later.
