The dynamic performance of grid-connected fixed-speed Wind Turbine Generator

The penetration of Wind Turbine Generator (WTG) into the power system has been increasing. As a result, the dynamic characteristic of WTG should be carefully studied to see its effect to the power system. This paper presents the dynamic study of fixed-speed WTG connected to the grid. The one-mass and two-mass shaft model are incorporated into the study to see their effect on the system dynamic. The observations are carried out during the dynamic of wind speed and fault condition. Matlab/Simulink is used to simulate the system. The result shows that two-mass shaft model is able to predict the behavior more accurate that that of in one-mass shaft model.
