Wind turbine control based on a permanent magnet synchronous generator connected to an Isolated electrical network

Abstract

In this paper, we study the modeling and control of the permanent magnet synchronous generator (PMSG) based wind turbine associated with a back-to-back converter connected to an isolated electrical network. The growth in exploiting renewable energy resources due to their availability and environmental advantages is the inevitable trend of electricity generation. In this paper, we use a voltage control strategy for a three-level PWM converter based on voltage oriented control (VOC), which guarantees high dynamic and static performance via an internal current control. The space vector pulse width modulation (SVPWM) with VOC is adopted to control the three-phase voltage source converter (VSC), to minimize the grid side current harmonics, active and reactive currents are controlled, respectively, in a d-q rotating coordinate system to achieve a unit power factor. The performance of the proposed overall system is evaluated using MATLAB/Simulink software by performing various simulations.
