Paper Abstract

In the solar tower thermal power generation system, the precision of the slope angle of the heliostat is the major factor, which influences the efficiency of the system, consequently, this angle should be tested accurately. In this paper, the methods based on laser deflectometry are proposed to measure the shape error of the mirror facet and the connected error of the facets; such apparatus and corresponding software packages are developed. With the help of these two apparatus, the heliostat of 1002, consisting of 55 mirror facets of 1.8182 m2; (hexagon), for the 1MWe solar tower power plant in Beijing are measured and connected successfully.
