Abstract

The invention discloses a rose diagram layout method for a heliostat field of a tower-type solar thermal power station, belongs to the field of heliostat fields of tower-type solar thermal power generation systems, and aims to solve the problems that the freedom of an existing circular staggered arrangement heliostat field is limited, and each heliostat is not arranged at the respective optimal position of the heliostat and is not the optimal layout. The method comprises the following steps: step 1, establishing a coordinate system by taking a receiving tower as an original point, and settinga densest circular staggered mirror field; step 2, dividing the densest circular staggered mirror field into k fan-shaped regions, wherein the central angles of the fan-shaped regions are respectivelyalpha1, alpha2... alphak; and step 3, independently optimizing the densest circle staggered mirror field in each fan-shaped area to achieve the highest comprehensive light efficiency, and the optimization being to adjust the radius of each row of heliostats in any fan-shaped area.

Description

technical field [0001] The invention belongs to the field of mirror fields of tower-type solar thermal power generation systems, and relates to a method for arranging heliostat mirror fields. Background technique [0002] As a renewable and clean energy source, solar energy has attracted widespread attention. Tower-type solar thermal power generation technology has become the main direction of large-scale application in the photothermal industry in the future due to its advantages of high heat collection efficiency, high thermal conversion efficiency, high overall system efficiency, large space for cost reduction, and suitable for large-scale applications. [0003] In tower solar power plants, heliostats reflect the sun's rays and transfer them to energy-absorbing towers for solar power generation. The arrangement of many heliostats in a heliostat field is an important factor affecting power generation efficiency and investment cost. There are two main types of existing he...
