加温模拟退火算法 应用 matlab程序(Heating simulated annealing algorithm in matlab program )

提出一种基于Teager能量算子的小电流接地 系统的单相故障选线方法。通过EMD时空滤 波，在故障线路零序电流中提取暂态分量作 为特征量，以Teager能量算子法求得暂态分 量的瞬时频率、实际频率和幅值，进而得到 信号的能量均值，再以能量均值为故障判 据，从而检测出故障线路。经Matlab/Simulink 仿真验证，结果表明该方法的有效性，且算 法简便(Single-phase fault line selection method for the system. Time-space filtering through EMD)
