Abstract

In this paper grid-voltage oriented control of grid-side converter for wind power system is presented, which aims to optimize the performance of utility grid during transient conditions. To realize this objective, a digitally controlled inverter system is implemented which provides independent control of active and reactive power delivered to the grid under sudden change in reactive load. Initially, the proposed grid-voltage oriented control scheme is analyzed in order to manage the power flows into the grid followed by the mathematical modelling of grid-side converter. And then, a closed-loop control structure of the grid-side converter is implemented using a conventional proportional integral (PI) controller with space vector pulse width modulation (SVPWM) current controller. In order to analyze the results of the proposed study, in this paper, the complete system is modelled and simulated in the MATLAB/Simulink environment and the numerical results are discussed. The experimental results, obtained using DSP TMS320F2812 processor, confirm the high performance of the proposed control system in terms of good sinusoidal grid current, low harmonic content and fast dynamic response.
