Method of Investigation of Generator Parameters Influence on the Efficiency of Small Wind Turbines
The results of theoretic and experimental study concerning the mathematical modeling of small wind turbine (SWT) were presented. Aerodynamic torque acting upon blades of turbine was modeled by quasi-static approach. The electrical torque acting upon the rotor was assumed as a linear function of current in circuit “generator-consumer”. Basing on the finite-dimensional mathematical model of SWT we proposed an analytical and experimental technique to measure the aerodynamic torque as a function of the propeller angular speed. The results of measurements allowed performing a numerical simulation of SWT work. The technique was verified on a mass-produced SWT.
