摘    要:输电线路双端频域法故障测距中,考虑线路参数自适应等因素后测距观测方程未知量个数将大大增加.为此,提出一种基于模拟退火-最小二乘混合的输电线路参数自适应故障测距算法,该算法充分利用了模拟退火法的全局搜索能力以及最小二乘法在初值良好情况下快速寻优能力,能有效求解含多个未知数的测距观测方程.基于EMTP的大量仿真计算验证了该算法具有较高的计算精度和稳定性.

关 键 词:故障测距  频域法  双端数据  模拟退火  最小二乘

Abstract:Considering the aspect of uncertainty on line parameters,double-terminated fault location schemes are suffering from the difficulties of solving multi-dimensional functions.An algorithm combining the simulated annealing(SA) algorithm and least squares method(LSM) was proposed for the fault location scheme containing various unknown line parameters in the paper.The algorithm inherited the global optimal convergence ability of SA and the fast convergence ability of LSM with a good initial value,which made it ...
Keywords:fault location  frequency domain  two-terminal data  simulated annealing  least square
