Abstract:
This paper analyzes a principle of one-cycle control, and proposes a one-cycle control for fully rated converter of permanent magnet synchronous generator( PMSG) wind power system on grid-side. With the output current as integral reference and grid voltage as the comparative reference, the output current is always tracking the output voltage. It aims to automatically adjust power factor and can effectively inhibit DC bus voltage fluctuation from impacting output voltage, and to improve low voltage ride-through( LVRT) capability of PMSG wind power system. The model and its control strategy are created in PSCAD/EMTDC. The simulation results show the correctness and validity of one-cycle control strategy.
