Title  An Integrated Structure/Control Design Method for Wind Turbine Simulator
Abstract
With the growing of global energy crisis and concerns about the environment, wind power generation achieves more and more attention due to its cleanliness, reproduction and other advantages. For further researching into wind energy conversion technique, wind turbine simulator (WTS) is of great help because it can reproduce the dynamic characteristic of field wind turbine in the lab conveniently. The paper aims at simulating the operation principle of field wind turbines by compensating the inertia of wind turbine simulator.

Firstly, the static and dynamic characteristics of the output torque of wind turbines under the condition of natural wind is analyzed, And the corresponding mathematical model of wind turbines is established in MATLAB/Simulink. Considering the effect of large moment inertia of field wind turbines, dynamic torque compensation strategy based on acceleration feedback is utilized to emulate the dynamic performance of wind turbines. Then, the influence of the low pass filter (LPF) in the compensation loop on the inertia compensation strategy is discussed based on numerical simulations. On this basis, the coupling relationship between the control parameter( time constant of the LPF) and the structure parameter( moment inertia of the simulator) is analyzed carefully. Finally, this paper briefly discusses the design method of the wind turbine simulator considering both structural parameters and control design.
