| dc.description.abstract | In this thesis, we use our program to design quickly aspheric curvature and conic constant of solar concentrator, also quickly and simply analyze all kinds of solar concentrators. Not only to design aspheric concentrators, but also to design another type which curve is composed of straight line. The concentrator is easy to manufactures and is quite cheap. It also can make a large concentrator, and it is also cheap.
In the part of double reflective aspheric mirror, it includes two type. One is paraboloid－hyperboloid, and other is paraboloid－ellipe. The two types both use our program to design all kinds and to analyze. To analyze concentrator ratio, spot size, the second surface size and distance of the two surface. In specific condition, the two types have the highest concentrator ratio. All kinds of solar concentrator, the concentrator ratio of paraboloid－ellipe concentrator is the highest. The paraboloid－ellipe concentrator has the highest concentrator ratio which is 8404. The paraboloid－hyperboloid concentrator has the highest concentrator ratio which is 8029. After designing concentrator, we must analyze error angle of tracking and manufacture tolerances. According to the influence of error angle of tracking to consider that the concentrator has much concentrator ratio drop above a special error angle of tracking.
In the part of many rings type double reflective concentrator, also use our program to design all kinds. We use ASAP to simulate that real sunlight concentrate. We also must analyze error angle of tracking. The many rings type concentrator have some manufacture defect, so alter the many rings type concentrator to become amelioration type which is more easy to manufacture. | en_US |
