Research on the Voltage Stability Control for Wind Turbine Group Based on Dynamic Reactive Power Compensation

To solve the problem of voltage fluctuation during the integration into grid and the operation of wind turbine groups, this paper proposes the voltage stability control method for Wind turbine group based on dynamic reactive power compensation. After the introduction of the theory, this paper discussed the voltage stability control strategy for Wind turbine group based on dynamic reactive power compensation on the basis of the study on mathematical model and voltage fluctuation characteristic of wind farms. By using the Matlab/Simulink simulation software, instances simulation has been made. The Simulation results show that this method can provide dynamic voltage support, stabilize bus voltage of wind turbine group in wind farms, and effectively improve the system´s operational characteristics. This method can also be applied to the dynamic reactive power compensation and voltage stability control of other asynchronous generator groups and asynchronous motor generator groups.
