Modeling and simulation of a brushless DC permanent-magnet generator-based wind energy conversion system

Abstract

This paper deals with a brushless DC (BLDC) generator-based wind energy conversion system (WECS) for distributed electric power generation. Threephase PWM rectifier and maximum-power-point-tracking algorithm are used for controlling the BLDC generator speed to achieve optimum energy output from the wind turbine. A PWM voltage-source inverter is connected to the DC bus for voltage and frequency regulation of AC supply to consumer loads. The BLDC generator-based WECS is modeled by sub-systems, and its dynamic behavior is simulated in MATLAB/SIMULINK environment for different wind-speed conditions and consumer loads. Keywords-brushless DC permanent-magnet generator, wind energy conversion system, simulation model, MPPT control, trapezoidal back-EMF.I.

“…Semi-analytical simulation model [6], [7]: This second model (Fig. 2b) is developed to take into account the switching pattern that depends on rotor angular position, the hysteresis current-control, as well as the commutation and conduction intervals of the controlled pulse width modulation (PWM) rectifier.…”

“…In order to speed up its evaluation a wind speed cycle partition technique based on barycenter method is adapted to the maximum power point tracking (MPPT) operation area of the wind turbine and implemented in terms of wind energy system power losses. The adopted MPPT control strategy corresponds to an operation of the wind turbine at optimal power coefficient ( _ ) and optimal tip-speed ratio ( ) [7]. The barycenter method divides the wind speed profile into a chosen number of regions ( Fig.…”
