Before I start discussing the relevance and the importance of the thesis topic, let me first give you a little situation sketch about our project.
The topic we are working on concerns the development of a renewable power system for a floating Lidar or Flidar. A Lidar (light detection and ranging) is a appliance that is capable of measuring wind speeds by sending and catching beams of light. The light emitted by the Lidar is reflected by airborne particles like dust, pollen, water droplets which cause a slight change in the frequency of the backscattered light. This principle is known as the Doppler effect and can be used to calculate the wind speeds.
Before building a new wind farm a Lidar is used to gather data about the wind quality on the building site. For onshore projects a Lidar can be placed upon the site and data can be analyzed quite easily. Offshore the situation is slightly different, a platform has to be constructed to support the Lidar and other measuring equipment. This already requires a serious investment without knowing if the site offers opportunities for a new wind farm.
The company we work with is called 3E (www.3e.eu) and they are commercializing a solution to overcome this high investment and still gather the necessary data. By attaching the Lidar on a buoy and thus creating a floating Lidar or Flidar drastic cost reductions are possible. The Flidar is designed to operate maintenance free and autonomous for more than six months in demanding offshore environments such as the European North sea area. The buoy and its equipment is fully powered by renewable energy from solar panels and wind turbines.
Our thesis consists out of redesigning and improving the power system and come up with creative and innovative solutions to improve energy, space and cost efficiency.
I hope this short introduction helps you to understand what Tijl and I will be doing as a thesis. If you have any questions, remarks or if you would like some extra information, don’t hesitate to leave a comment.
