Abstract
This paper presents the simulation of a tethered lifting device for wind power
generation using Simulink®. An explanation of the underlying power extraction
methodology will precede a description of the mathematical model. Heuristic
controls are then developed to demonstrate net power generation using a tethered
aircraft. This work serves as an in principal demonstration of wind power
generation using a tethered aircraft.
Keywords: tether, winch, control, kite, generator, renewable, energy, wind,
glider, altitude.
1 Introduction
Reclining fossil fuel reserves, increasing carbon emissions and increasingly fast
climate change are profound reasons to pursue renewable, environmentally
friendly sources of energy. Wind energy is a well-known alternative to nonrenewable
energy and usually brings the image of a windmill or wind turbine to
mind, a beautiful structure pointing out from the earth with large blades rotating
majestically about the hub. In this work however we look at harnessing high
altitude wind energy due to the fact that it is much more consistent and is of
much higher potential [1].
There have been several proposed methods of extracting high altitude wind
energy. The work of Fletcher et al. [2] explored several variants of tethered
turbine generators with Fletcher and Roberts exploring high altitude wind energy
resources in earlier work [1]. The crux of their ideas was to place a turbine at
altitude, tethered to the ground with energy travelling down a conductive cable.
Lloyd proposed the flying of closed loop orbits to increase the apparent wind and
hence available power for a kite based generator either as a towing device or
with on board turbines [3].
