Tiivistelmä
Wind turbines for electric power generation has become a widespread notion as it is one of the cleanest and safest ways to meet the enormous demand of power without causing any significant harm to the environment. In this experimental research, the potential of wind energy and its possible application in household heating by converting wind power to thermal power via hydraulics is explored.
The experimental set-up comprised of an AC-motor attached to a variable displacement pump, a frequency converter, a pressure relief valve and several other equipment including sensors for data measurement. Hardware in-the-loop (HIL) simulation is applied where, the virtual turbine model developed in Simulink and integrated with dSPACE controller controls the AC-motor to generate flow. Regulation of valve orifice creates pressure drop, as a result, heat is generated which is measured in terms of thermal power.
Horizontal axis wind turbine (HAWT) is chosen as the virtual turbine model whose design parameters are as same as the real Aeolos wind turbine model. The output power obtained from the real-time simulation is compared with the power curve of the Aeolos turbine to validate the performance similarities between the two.
