HHT energy spectrum based identification method for lightning fault

The accurate identification of lightning fault has very important significance to the lightning protection of the lines. A new identification method of is proposed in this paper. HHT transform is used to identify lightning faults and short circuit faults. Compared with wavelet transform method, it has no selection problem of transformation parameter, and the transform result has its uniqueness. The simulation results indicate that lightning fault and common fault will be identified correctly, and depend on this method the accuracy of identification will also be improved. Developing solar thermal power technology in an effective manner is a great challenge in China. In this paper an experiment.
