摘　　要：从实现配电网自动化实际难题出发,设计了一种成本低,体积小,安装方便的基于载波通信的电子式电流测量终端。设计采用印制电路板(PCB)制作Rogowski线圈,用DSP对数字信号进行积分还原出电流信号,用插值法实现测量同步。很好的解决了实现配电网自动化过程中网络结构复杂,测量终端多,资金不足等难题,有很好的应用前景。This paper aim at actual realization of the distribution automation problems, design a low cost, small size, easy - to - install, carrier communication style electronic current measurement terminal. This design use printed circuit board （PCB） to product Rogowski coil, use DSP achieve integration to restore current signal , use inserting data to achieve synchronization. Satisfactorily resolved the problem such as network complex structure, multi - terminal measurement shortage of funds In the process of achieving distribution automation , there are good prospects.
