Assessment of vector controlled asymmetrical two-phase induction generator driven by wind turbine simulator

Abstract

This paper presents the assessment of the vector control for a two-phase induction generator (TPIG) driven by a wind turbine simulator. The structure of this system consists of two sections. The first section is a wind turbine simulator using a dc motor drive performed by a torque control for providing mechanical power to TPIG. The second section is the three-leg voltage source inverter connected TPIG which is governed by the indirect vector control. This strategy offers the independent controls between flux and torque of TPIG and its improved performance by compensated stator currents. Matlab/Simulink software is applied to the proposed system under various conditions. The simulation results of dynamic response for the proposed vector control are commanded by the wind turbine simulator providing the torque-speed characteristics of a small wind turbine and conclude that TPIG can be used for wind energy applications.
