Review and Economic Research on Solar Field Design of Solar Tower Plants

Abstract

[Introduction] The paper aims to sort out the contents of the design of solar field of the solar tower plant systematically and to evaluate the impact of solar field design on the economy of the plant. The solar field design is summarized and introduced. The factors affecting solar field efficiency is analyzed and the economic research is conducted. [Method] The design of the collector field was divided into three parts: design of the position and height of the receiver, design of the heliostat layout and design of the road in solar field. The method of decomposing the sub efficiencies of solar field efficiency was adopted and the research was focused on the two main design factors that affect the economy of the solar field. [Result] In this paper, several factors that need to be considered in the design of solar field are summarized and the design conclusions of various factors to improve the efficiency of solar field are listed. Under the current engineering conditions, the larger solar field results in a better the economy of the plant. The influence of the density of the heliostat layout on the economy is obtained. [Conclusion] The conclusions are of great guiding significance and can be used for reference in the design of solar tower plant.
