The ray tracing is used for the calculation of the optical efficiency of field. The mathematical theory of the calculation is derived. The parametric search algorithm  which allows variation of the field parameters within a specified range  is used for the optimization of field. The field layout is made automatically according to the no-blocking loss condition and the heliostats are located at the positions where the annual incident cosine value is higher. In this way  the blocking and cosine losses are lowered. Because the optimization of the distance between fore-and-aft two rows of heliostat is avoided  the computer time is reduced effectively. Using this procedure the heliostat field of a 1MWe solar tower power plant was designed. Four modes of layout including North-South cornfield  North-South stagger  Radial cornfield and Radial stagger were experimented and optimized respectively. The comparison of the field efficiency for the four optimized results was made. It is concluded that the North-South cornfield layout is the optimal decision for the 1MWe solar tower power plant.   Shape and alignment measurement of the heliostat by laser deflectometry (EI CONFERENCE) 会议论文 Optical Modeling and Measurements for Solar Energy Systems II, August 13, 2008 - August 14, 2008, San Diego, CA, United states Xu W.; Lu Z.; Liu H.; Zhang H.; Ni Z. 收藏  |  浏览/下载：13/0  |  提交时间：2013/03/25 In the solar tower thermal power generation system  such apparatus and corresponding software packages are developed. With the help of these two apparatus  (hexagon)  the precision of the slope angle of the heliostat is the major factor  the heliostat of 1002  for the 1MWe solar tower power plant in Beijing are measured and connected successfully.  which influences the efficiency of the system  consisting of 55 mirror facets of 1.8182 m2  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   Optimization procedure for design of heliostat field layout of a 1MWe solar tower thermal power plant - art. no. 684119 会议论文 2008 Wei X.
