Abstract:On the basis of empirical mode decomposition(EMD) and approximate entropy,a new approach to diagnose the fault type for transmission line in single-phase grounding fault is proposed.The method has anti-interference ability,can diagnose the fault type rapidly and improve the success rate for reclosure.Simulation results show that the method is valid and practical.
Keywords:empirical mode decomposition(EMD)  approximate entropy  single-phase adaptive reclosure  transient faults  permanent faults
