摘　　要：在配电网中性点非有效接地系统中,发生单相接地故障时,高效、快速、准确采集较多电压、电流对正确判断故障是一个非常关键的问题。针对这个问题,提出了使用AD7864与数字信号处理器TMS320LF2407构成数据采集系统的方案,给出了A/D转换芯片AD7864与数字信号处理器TMS320LF2407的接口方法及在数据采集平台中的应用,并给出了硬件和软件设计。When phase to earth fault occurs on a nutral nondirect guounded power system, it is very important to sample the voltage and current parameters quickly and accurately for selecting the faulted circuit. Aiming at this question, this paper presents a project based on AD7864 and TMS320LF2407. It introduces the interface between AD7864 and TMS320LF2407, it also gives the application to the Data System. The design of hardware and software is also introduced in this paper.
