摘　　要：针对当前站所终端(Distribution Terminal Unit,DTU)电流接口不一致的问题,提出一种加装电流互感器的DTU检测台体设计方案。该方案在原有检测台体的基础上创新性地增加了有源补偿电流互感器。详细阐述了检测台体设计方案、误差计算及补偿和准确度测试等内容,通过智能配电网中心近一年的检测运行,证实了所提方案能够解决电流接口不一致问题。Aiming at the problem of inconsistent current interface of the DTU,a design scheme of DTU testing platform with current transformer is proposed,This scheme innovatively adds active compensation current transformers on the basis of the original testing platform.The design scheme of the testing platform is introduced,error calculation and compensation,accuracy testing,etc.The intelligent distribution network center’s testing operation for nearly1 year has confirmed that the proposed scheme can solve the problem of inconsistency of the current interface.
