Abstract

The invention discloses a method for designing a disc type Stirling solar disc surface reflecting target. The method comprises the following steps of 1) constructing a disc surface simulation model on simulation software according to the actual surface of a disc surface; 2) adjusting a position of each mirror surface in the simulation model to make the disc surface converge solar radiation in a receiving plane uniformly; 3) separately extracting a reflecting light spot image of each mirror surface according to the result; 4) computing an energy center position of a light spot and taking the position coordinates as a target point corresponding to the mirror surface; and 5) repeating the step 3) to step 4) and computing target points corresponding to all mirror surfaces; and drawing the all target points on the plane to obtain the target. The invention provides the method for designing the disc type Stirling solar disc surface reflecting target, which has higher efficiency and higher precision.

Description

technical field [0001] The technology belongs to the field of concentrating thermal power generation in solar energy, specifically the field of dish-type Stirling solar power generation technology, in particular a method for designing a dish-type Stirling solar dish surface reflection target. Background technique [0002] Due to the continuous consumption and limitation of traditional energy sources, sustainable and clean energy sources are increasingly valued by society, among which solar energy has become one of the hottest research topics. Dish Stirling solar energy is currently the solar energy utilization technology with the highest photoelectric conversion efficiency. It uses a giant parabolic dish to gather sunlight, and forms a high-energy-density spot near its focus, that is, a radiation source, and then drives the Stirling engine and generator located here to realize the conversion of light energy into electrical energy. During this process, a high-quality light s...
