Abstract

Dynamic performance investigation of Wind Turbine (WT) implementing Permanent Magnet Synchronous Generator (PMSG) under variable wind speeds and load circumstances are investigated in this paper. The injected active and reactive power respectively regulate by d-axis current and q-axis current using active and reactive power (P-Q) control method. The P-Q controller can adjust DC link voltage, active and reactive power. The generated reactive power via the WT is adjusted at zero so that the Power Factor (PF) is retained unity. The proposed system is containing of WT, PMSG, rectifier, a DC bus by capacitor and voltage source inverter. The simulation results depict the accuracy and credibility of the WT and the strategy of inverter controller. The thorough Wind Power Generation System (WPGS) and power electronic converters interfaces are proposed by using Matlab/Simulink.
