Abstract

The control characteristics of the ac/dc grid-side voltage source converter (VSC) used to connect wind power systems with the grid are of significant grandness for the overall grid execution. In this paper, voltage oriented control PI and phase locked loop (PLL) are used to regulate grid-side dc voltage and system power factor by decoupled control theory. The mathematical models of grid-side converter and the control strategy of grid-side converter based wind power generation system are analyzed. The control performance is assessed through simulation approach using MatLab SimPowerSystem, which verifies that the developed control mechanism is feasible to apply for grid-side converter based wind power generation system and the grid-side converter is controlled well.
