Development of Co-simulation and Analysis by Combination of Aerodynamics, Mechanism Dynamics and Control System Dynamics for Large Wind Turbines

The objective of the paper is to develop a novel co- simulation analytic interface of aerodynamics, mechanism dynamics and control system dynamics for 2MW wind turbines. Therefore, three software, such as FAST, ADAMS, and MATLAB/ SIMULINK, are integrated into one interface to combine with aerodynamic, mechanism dynamic and control system dynamic simulation. The dynamic response of blades, transmission system, and other subsystems can be simulated under different input circumstances of wind. The closed-loop simulation of the pitch control and the yaw control of cabinet can both be performed. Finally, the co-simulation results of the 2MW wind turbine will be verified by verification, and the results shows that the co-simulation analysis of aerodynamics, mechanism dynamics and control system dynamics for 2MW wind turbines developed in this paper can describe the overall system characteristics satisfactorily.
