In this paper, a torque control algorithm for direct drive wind turbines using a twelve-phase permanent magnet synchronous electrical machine is proposed. An electrical machine oriented to output four independent 3-phase star subsystems have been introduced in order to improve direct drive wind turbine torque control, power generation and reliability. A specific coordinate transformation for multi-phase electrical machine control that allows the independent and decoupled management of each electric three-phase subsystem has been developed. The synthesis and the simulation results of the proposed control algorithm are presented.

Abstract

In this paper, a torque control algorithm for direct drive wind turbines using a twelve-phase permanent magnet synchronous electrical machine is proposed. An electrical machine oriented to output four independent 3-phase star subsystems have been introduced in order to improve direct drive wind turbine torque control, power generation and reliability. A specific coordinate transformation for multi-phase electrical machine control that allows the independent and decoupled management of each electric three-phase subsystem has been developed. The synthesis and the simulation results of the proposed control algorithm are presented.
