| Abstract |
The paper presents a modeling of the grid-connected wind turbine generation system on MATLAB/Simulink and aims to perform simulations for analysis of the system"s characteristics. It performs a pitch regulation for control of the wind generator’s output with respect to wind speed variation, and presents a relationship between interconnecting transformer"s connections and fault current by reviewing the variations of fault current according to transformer connections in a grid-connected wind power generation system. It also investigates the effect of grounding methods of the interconnecting transformer’s neutral point on fault current variations. The simulation results show the differences of fault currents, voltages and generator’s characteristics for a line-to-ground fault according to interconnecting transformer’s four different connections, and the differences of fault currents of the system according to grounding methods of the transformer neutral point. Therefore, the case studies demonstrate the effectiveness of the proposed simulation model on Simulink. |
