摘　　要：考虑到煤矿对供电性能的特殊要求,以提高故障定位的速动性和准确性为目标,设计了一个煤矿电缆短路故障测距系统。测距系统以数字信号处理器TMS320F2812为核心控制器,运用小波变换和奇异性检测理论作为故障信号处理技术,可以实现快速、准确的煤矿电缆短路故障定位。仿真实验结果表明系统具有优良的故障测距性能。Considering the special requirements of power supply in mine coal, we designed a new mine cable fault locating system to im- prove the precision and speed of fault location. The mine cable fault location system chooses DSP chip TMS320VC5507 as the central processing unit, and can realize the fault location of mine cable quickly and accurately by applying wavelet transformation and singulari- ty detection theory as fauh signal processing technology. The simulation results show excellent fault location performance of the system.
