Description
Summary:Due to the inaccuracy of the grid-side inductance, the existing control strategies for grid-side converters of Wind Energy Conversion System (WECS) has poor control performance. By introducing the concept of complex vector, this paper converts the grid-side converter of WECS from the double-input and double-output coupling system to the single-input and single-output first-order system. Based on this, the performance of the grid-side converter system is deeply analyzed, and a control strategy for the grid-side converter with no inductance value is proposed, with the generator-side converter control strategy together, the WECS control system is established. The simulation results show that the grid-side current waveform is obviously improved after adopting this control system, which makes the WECS have excellent static and dynamic performance, and greatly improves the adaptive capacity of WECS.
