Interfacing of Grid Connected Wind Energy Conversion System Based on PMSG through NPC Inverter

Wind energy is a prominent area of application of variable-speed generators operating on the constant grid frequency. This paper describes the simulation, operation and control of one of these variable-speed wind generators: the direct driven permanent magnet synchronous generator (PMSG). This generator is connected to the off-grid load. The generator is controlled to obtain maximum power from the incident wind with maximum efficiency under different load conditions. Pitch angle control is designed to extract the power from the wind when speed is more than the base speed. This paper shows the dynamic performance of the complete system. Different tests in a 8.5-kW prototype have been carried out to verify the benefits of the proposed system.
