The Novel Control Technology of Wind Turbine in VSCF Wind Power Generation System

Abstract

In order to make wind power generation system connect to the grid normally in the grid voltage transient fault, it is required in grid security standards that wind power generation system has some capability of fault run-through. The nonlinear controller was designed based on feedback linearization technique. The controller's main purpose is to improve the wind power system steady state performance while to gain better dynamic response speed via controlling the motor terminal voltage and rotor rotation angle. Simulation results indicated that the proposed method could improve the dynamic response speed, as well as improve the steady performance of the wind power generation system.
