Research on Automatic Adaptation Method for Reflector of Linear Fresnel Collector

For the solar linear Fresnel collector, the arc of the primary reflective mirror is usually fixed to a certain degree, because of which, the light spot will be oversized when the solar incident angle varies within a certain range, thus affecting the concentration effect and the collecting efficiency. Moreover, the "edge effect" of the reflective mirror also has a detrimental effect on the concentration accuracy. Based on the theoretical analysis, this paper proposes a method to automatically adjust the arc of the primary reflective mirror in accordance with tracking angle, and then the method of solving the problem of edge effect is also suggested.
