Developing a controller for a sun tracking MaReCo hybride in Hammarby Sjöstad (English)
Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating. According to the development in digital technology with lower prices on advanced semiconductors as a consequence, the conclusion is that the prerequisites of this concept will be even better in the future. The result of this thesis is a heliostat function that increases the energy gain by up to 40%, compared to a field of MaReCo collectors without this function. Though, the cost only increases by 13%.
