Modeling and Grid Stability Simulation of Wind Power Generation Systems
In order to explore the stability characteristics of wind power generation systems when connected to the grid,a corresponding simulation model was established,including three key universal modules:Wind speed,wind turbine,and mechanical transmission.Based on this,a doubly fed wind turbine connected model was constructed using Simulink software in conjunction with the actual situation of a wind farm.Under voltage control mode and reactive power control,grid connection stability simulations were conducted at different wind speeds,and corresponding technical characteristics were obtained.The results show that the terminal voltage,terminal current,active power,reactive power,motor speed,and wind speed of wind turbines are closely related,and all indicators can reach a stable state again after fluctuations.
