Modeling of the Wind Turbine with a Permanent Magnet Synchronous Generator for Integration

Abstract

The paper presents the dynamic model and control schemes of a variable speed pitch wind turbine with permanent magnet synchronous generator (PMSG). The model includes a PMSG model, a pitch-angled controlled wind turbine model and a drive train model. The drive train model uses one-mass model to represent the mechanical characteristics of the generator set. The generator model is established in the dq-synchronous rotating reference frame. The wind turbine model details the mechanism of variable speed operation of the turbine by a pitch control. The control schemes in the paper include a pitch angle control for the wind turbine and a speed control for the generator. The pitch angle control uses wind speeds and electric power output as the input signals to ensure normal operation in high wind speed. The speed control is realized through field orientation where the d-axis current is set to zero and the q-axis current is used to control the rotational speed of the generator according to the variation of wind speed. In order to verify the presented model and the control strategy, simulations with MATLAB/Simulink software have been conducted. Simulation results prove the validity of the model and the control schemes.

Dynamical Behavior of a Wind Turbine Power Train Considering a Rotor-Gearbox-Generator Coupled Model

“…Peeters [16][17], Todorov [18], WeiShi [20], Datong [5], Wang [21] and Helsen [8]studied mathematical models related to the gearbox of wind turbines (the mechanical part of the power train). Regarding the generator, Marques [13], Bernardes [2], Ming Yin [14], Bastos [1] and Lei [11]studied mathematical models related to the generator. Vásques [19] developed mathematical models of permanent magnet synchronous generators for hydrokinetic systems.…”

“…The model of the PMSG was developed in the dq synchronous reference frame, where the q-axis is 90 deg phase shifted ahead of the d-axis with respect to the direction of rotation [13]. In order to simplify the system, the generator was assumed to be a PMSG with surface-mounted magnets.…”

“…Thus, the model of the PMSG in the dq synchronous reference frame is given by the voltage equations (2) and (3), the torque equation (4) and the mechanical equation (5). N p represents the number of the pole-pairs [13], [14]- [18]. Remark,the parameter of PMSG is taken as a black box and thus detail is not considered in this paper.…”
