Wind turbine generation is rapidly becoming the preferred renewable source of electric energy. This paper presents the modelling and simulation of a wind turbine energy conversion system connected to the power grid. The wind turbine being considered is a variable-speed variable-pitch turbine connected to a speed-multiplying gear box to move a 3-phase wound rotor synchronous generator. The variable frequency energy produced by the generator is converted to the 60 Hz power system energy by a full power AC/DC/AC electronic converter. The control system comprises the feedback control loops for turbine, generator, rectifier and inverter. Active and reactive powers are controlled at the point of interconnection. Simulation experiments are presented for each subsystem. Results reveal appropriate performance of the whole wind turbine generator model.
