| Abstract: | The recognition method for 4 common transient signals: single-phase short circuit,fault lightning strike,non-fault lightning strike,capacitor switch is proposed based on S transform.These 4 transient signals are generated at 500 kV transmission line simulation model by PSCAD/EMTDC,and then the sum of transient energies of different frequency are picked up from these singles by using S transform,and recognition criterions are obtained by analysis and comparison.Examples results show that the proposed method ... |
