基于DSP的配电线路故障测距研究

The study on the application of DSP technology in the power circuit fault location system

针对电缆故障在线测距对实时性和准确性的要求,采用高速AD转换芯片AD9238和DSP芯片TMS320C6713设计了双通道高速数据采集系统,并将其应用于电力系统故障测距.实验表明,数据采集精度高,数据处理的速度快,实时性好,故障测距准确.

According to the cable fault location for real - time and accuracy requirements, the author designs a high -speed data acquisition system of double channel, with high -speed AD9238and TMS320C6713, and applied to power system fault location. This method can improve the precision of data acquisition and data pro- cessing speed, troubleshooting data computation complexity and real - time problem, to ensure the accuracy of fault location.
