Development of a useful wind turbine emulator based on permanent magnet DC motor

摘要

In order to provide a testing for Wind Energy Conversion Systems (WECS) control strategies, a Wind Turbine Emulator (WTE) was designed and realized. The experimental implementation of the WTE for WECS consists of permanent magnet DC motor controlled by Pulse-Width Modulated (PWM). A DC motor is used to generate speed and torque required by the aero generator (PMSG) for producing electrical power. The control of a permanent magnet DC motor and the mathematical model of the wind turbine are elaborated using Matlab/Simulink platform. Results confirm that the WTE can provide all necessary parameters of the wind turbine system such as wind speed, output torque, power coefficient and tip speed ratio.
