Emulation of wind turbine using dc motor

Abstract

Over the course of the past few decades, there has been a steady rise in the utilization of renewable energy resources. 238GW is the estimated global wind capacity at the end of 2011. India is the 5th largest harnesser of wind power with 16GW production. Wind energy is green and clean compared to non-renewable fossil fuels and thus wind energy based power generation has become a significant contributor to present power systems encouraging works on wind power based research. Since it is troublesome to practice a true wind turbine for research requirements, it gets necessary to create a replica of a genuine wind turbine to be utilized for small scale works. This paper depicts the configuration of a test system working on a wind turbine's power-speed characteristics. It concentrates on the power-speed and torque-speed characteristics and models the wind turbine characteristics reproducing the same utilizing MATLAB-SIMULINK. The work is on mathematical demonstration of test system of the Horizontal Axis Wind turbine. The corresponding static and dynamic characteristics recreations are done. Emulation of the wind turbine is done by working the DC motor to gauge the theoritical rotational velocity of the rotor of the wind turbine. A PI controller is utilized to tune the DC motor characteristics with the Wind Turbine characteristic curves. Taking into account the rotor characteristics of the wind turbine, a particular reference rotor pace is produced and the wind speed gives the mechanical wind power.
