Abstract
When the fusion efficiency is low , the method based on depth information fusion technology will directly af-fect the accuracy of the grounding line selection for small current .The EEMD and FFT are used respectively to ana-lyze the zero-sequence component of steady-state and transient , this paper sets up faulty measurement function to cal-culate fault measures of feeders and establishes fault measures of different methods based on information gain .Finally , sample fault measures are founded by fusing the two fault measures .Then, the depth information fusion line selection is conducted by using the least squares support vector machine ( LSSVM ) of the simplex optimum-seeking algorithm and the information gain degree with the sample fault measures as characteristic input .Simulation results show that the above method is of high accuracy and sensitivity in fault line selection .关键词
