摘　　要：从实现配电网自动化实际问题出发,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。From the problem of achieving distrubition network automation, electronic current measurement terminals of low cost, small in volume and convenient in installation based on carrier communication are designed. The design uses a printed circuit board to make Rogowski coil, uses DSP to integrate over digital signal and return to current signal, and uses interpolation method to achieve measurement synchronism. It has solved the problems for the network construction complication,multi-mearuring terminals and funds shortage in the process of achieving distrubition automation. It has a good application prospect.
