First simulation of the power flow

In order to help to understand what happens with the power flows of a single kite ground station, a simplified simulation with Matlab Simulink was made. This will help to understand how the electrical devices work and what their expected values for testing are.

It is important to clarify that this simulation does not have the purpose to show the power on absolutely all of the elements involved in the ground station. It only focuses on the main elements.

The main elements considered in the simulation are:
- Electrical Synchronous Motor
- DC Bus with storage (Battery)
- Grid / Generator
- Braking resistor

Notice that for example some elements like the inverter/rectifier are not there, the reason of this is that we only focus on the way the power flow through the system itself. As an input we have a squared wave, which is not exactly real, but it is good enough for the initial purpose of the simulation.

For a more in-depth purpose the second simulation was done, taking care about more elements, and the kind of energy that is flowing through them.

About SwissKitePower

pix

The SwissKitePower project is a multidisciplinary research and development effort aimed at creating a totally new device which can harness wind energy at high altitudes. The winds at altitude are stronger and more consistent than those at the ground and represent an enormous potential source of renewable energy.
