Modeling and Simulation of Doubly-fed Wind Turbine Based on the improved internal model - feedforward control strategy
Dealing with doubly- fed wind turbine torque disturbance on speed regulation performance and power grid fault for side control system bringing in many other adverse factors, this paper puts forward to improve internal model - feedforward cascade control strategy because single control strategy can not solve the above problems. Firstly , Based on the improved internal model control design of speed loop weaken mechanical torque disturbance influence on speed tracking performance. Secondly, internal model - feedforward control strategy is designed for rotor current loop .Finally, the doubly-fed wind turbine model built into the microgrid system is simulated under the condition of steady state and fault in MATLAB /SMIULINK.The simulation results show that the speed controler can achieve good tracking performance and higher steady state accuracy, rotor current loop controler improve the machine side and gridside transient performance,and the improved strategy is correct and effective.
