Abstract

The paper discusses implementation issues related to the control of a three-phase grid-inverter for a wind-turbine system (WTS). The grid-side converter is controlled in order to maintain constant the DC voltage also in presence of grid voltage variations and the sinusoidal currents in phase with the corresponding voltages. PI and P+Resonat controllers are considered. For the P+Resonant controller different digital implementations are evaluated: shift operator based and delta operator based. A performance comparison, in terms of the C-code execution time is presented. The control algorithm based on PI controller has been experimentally verified.
