Anti-power Interference Method Combining Iterative EMD-ICA and Levkov for Transient Response
In the process of acquiring transient response signals,power frequency interference and power frequency har-monic interference will inevitably be introduced,which feature non-stationary small signal,unfixed interference frequency swimming and frequency band aliasing,making the conventional methods inadaptable.Trying to address this problem,this paper proposes a transient response power frequency interference suppression method based on iterative EMD-ICA and Levkov combination.The EMD and ICA are combined,and the reference signal is constructed through EMD,so that the power frequency interference suppression can be carried out to meet the conditions of ICA use.The problems of power fre-quency swimming and power frequency harmonic interference are overcome by iterating EMD-ICA Levkov method,re-spectively.
