New Fault Discrimination under the Influence of Rayleigh Noise

Abstract

The researches in this paper mainly provide service for wide area adaptive backup protection. A new fault discriminant technology based on the criterion for fault category and non-fault category will be explored. In the researches, for the common fault types in power system, fully considering the influence of wind power, we have discussed the new fault discriminant technology under Rayleigh noise. Simulation results have shown that even there are random disturbances from Rayleigh noise, the criterion for fault category and non-fault category can still accurately identify system faults.
