N2 - Recently there has been an increasing interest in wind power generation systems. Among renewable sources of energy (excluding hydro power), wind energy offers the lowest cost. It is therefore imperative that basics of wind power generation be taught in the undergraduate electrical engineering curriculum. In this paper, an experiment that emulates wind turbine systems has been developed for this purpose. It is known that the power that can be drawn from the wind in a wind turbine depends on the wind speed and the speed at which the shaft of the turbine is rotated. The objective of this project was to emulate the behavior of such a system using two DC machines. One of the DC machines was operated under torque control. The torque reference for this machine was generated using the Power vs. Shaft speed curves for wind turbines. This DC machine emulated the wind turbine and shaft. The second DC machine was operated under speed control and this machine emulated the electrical generator. Simulations were performed to design such a system. The system was implemented in real-time using Simulink and dSPACE control platform. Two 200W DC machines rated at 40VDC and 4000 rpm were used. The DC machines were controlled using a pulse width modulated (PWM) power converter. This project was part of an undergraduate research supported by NSF and the University of Minnesota Research Experiences for Undergraduates (REU) program.
