Abstract

In this paper, a grid-tied wind system with three-phase and four wire is planned to operate under a variety of loading circumstances. It is proposed that a control technique be utilized in order to provide a reference current signal for the purpose of managing the operation of a three-phase four-wire parallel connected active power filter. When it comes to the generation of reference current, the synchronous reference frame (SRF) method based on time-domain has been widely acknowledged to come with the advantage of providing control simplicity. The parallel active power filter, also known as SAPF, is the most efficient method for reducing the effects of current harmonics. For example, the SRF approach, which was initially designed to function with a three-wire system, cannot be immediately used to a four-wire network without undergoing adjustments. As a result, a new topology is projected in order to accomplish the minimization of harmonic current under non-linear, step change, and/or unbalanced loads. Through the utilization of the MATLAB/Simulink software, the design structure of the proposed approach was developed.
