Modeling and simulation of grid side converter based wind power generation system

Voltage oriented control PI is combined with space vector modulation and phase locked loop to control the grid side converter in wind power generation system in this paper. First the mathematical models of grid side converter and LCL filter as well as grid are given. Then the control strategy of grid side converter-based wind power generation system is given in detail. Finally the simulation model consisting of the grid side converter wind power generation system is set up. The simulation results have verified that the control strategy is feasible to apply for gird side converter-based wind power generation system and the grid side converter is controlled well. It has laid a good basis for the real system development.
