Emulation of the Static and Dynamic Behavior of a Wind-Turbine Based on DC Motor

In this paper, the wind turbine characteristics are analyzed, and a wind turbine model is proposed, a simple and effective emulation scheme is built up based on torque control. A wind turbine emulation platform based on DSP and DC motor is set up, the supervisor system is designed and implemented using LABWINDOWS. The emulation system is used in a grid-connected variable speed constant frequency wind power system, it can emulate the static and dynamic behavior of a wind turbine, which satisfies the need of the system research, and makes the research on the wind power technology become very convenient in the laboratory conditions.
