Two different wind turbine technologies can be differentiated. The one technology is based on rotors that rotate around a vertical axis, the others around horizontal ones. Planned as a proposed solution are wind turbines that rely on the horizontal axis technology. This wind turbines consist in general from bottom to top of the following main parts: foundation, power connection, tower, powerhouse or rotorhouse, axis with gear or gearless, a generator and a rotor. A windturbines performance depends on various aspects, such as tower height, rotor diameter and wind occurance, also the technology inside the powerhouse plays a role. Wind turbines follow the function principle, that they convert the wind occuring at the loaction of the wind turbine via the rotor into kinetic energy. This kinetic energy is than translated via a generator into electrical energy. [1] [2] [3]
The installation of new wind turbines is dependent on energy and the budget that can be invested into new wind turbines and the maintainence of the existing wind turbines. The system wind turbines is therefore interrelated to the existing energy grid on the island in a mutual relationship. On the one hand it supplies energy and revenue in that sense that it makes economic ventures on the island possible on the other hand it demands energy and budget fur construction and maintenance.
The other proposed engineering systems for the integrated energy system for Bonaire are solar rooftops, biogas plants and sewer systems. All of these products are incorporated in overall maintenance strategies and are beeing assessed by a mulit- objective optimization.
