Signal Denoising for Single-line to Ground Fault in Disteibution Networks Based on Mathematical Morphology
Zhang Wei · Proceedings of the Chinese Society of Universities for Electric Power System and its Automation · 2011
Combining the characteristics of the signal for phase to ground fault in distribution network,a signal de-noising method with mathematical morphology was introduced,which process the data of phase to ground fault with the flat structure combined morphology filter.It can effectively de-noise the signals without changing the local characteristics of the original signals.Matlab simulation results verified the effectiveness of the proposed method.
