- Abstract
Partial discharge (PD) signals is one of the key means to judge the transformer fault, how to effectively remove interference of PD in the field is the key in PD monitoring. Based on the Hilbert transform, this paper proposes a new algorithm of signal decomposition of Variational Mode Decomposition (VMD) by using the de-noising in transformer PD signal, VMD can decompose signal into several modes, and each of them is compact around a center pulsation. The simulation results show that the proposed method can well remove the narrow-band periodic interference and white noise, and keep the partial discharge signal, verify the validity of VMD.
