Back to back tests simulations of an interior permanent magnet machine

Abstract

This paper investigates a back to back test simulation of an interior permanent magnet (IPM) synchronous machine with fractional slot concentrated windings (FSCW). The studied machine is designed to equip a floating vertical axis wind turbine. The principal characteristics and the structure of the machine are presented, as well as the back to back test principle. The parking brake mode is investigated to determine at which aerodynamic torque the system converters have to be started. The designed system and the simulations results, obtained with the Matlab-Simulink platform are described. Simulation results obtained with the proposed control are compared to those obtained with the equivalent single-phase diagram.
