摘要: Fast transient and smooth steady-state performance of wind energy conversion systems (WECSs) is essential for sustained power grid code fulfilment including low voltage ride through capability. In this paper, an analysis permanent magnet synchronous generator (PMSG)-based WECSs under vector control direct torque provides the basis combining salient features two methods into a reliable effective system to provide enhanced machine performance. The includes hysteresis current controllers in connection with inverter-switching table. proposed fast side converter PMSGs, which controls dc-link fault conditions. Extensive simulation results on 2-MW PMSG-based WECS demonstrate desired both grid-normal -fault
