Özet

In this paper, discrete wavelet transform (DWT) and symmetrical component (SC) analysis are used together for extracting the fundamental component and oscillations in supply current drawn by slip energy recovery drive (SERD). Discrete Meyer wavelet is used as mother wavelet due to its orthogonal and biorthogonal properties to generate reference signal for active power filter (APF) in order to compensate current harmonics. Simulations are performed using Matlab Simulink and Wavelet Toolbox. Simulation results show that the DWT algorithm can abstract the fundamental component of supply currents effectively and the oscillations in the supply currents are considerably reduced when the DWT is combined with SC analysis for generating the reference current of the APF.
