Abstract

The invention discloses an imaging method of a tower-type solar thermoelectric system mirror field based on a GPU. The imaging method of the tower-type solar thermoelectric system mirror field based on the GPU comprises the steps that (1) the time, heliostats, mirror field parameters and heat absorber parameters are determined; (2) a mirror field is generated, the position of the sun, the unit vector of main incident rays, the unit vector of main reflection rays of each heliostat, the unit normal vector of each heliostat and the cosine efficiency of each heliostat and the atmospheric transmission efficiency are calculated; (3) imaging calculation of each heliostat is carried out on the GPU in a multi-threading mode through a CUDA calculation platform; (4) the imaging calculation of all the heliostats are summarized, and a mirror field image is obtained. According to the imaging method of the tower-type solar thermoelectric system mirror field based on the GPU, a large amount of calculation and judgment is assisted by the high-speed calculation capacity of the CUDA calculation platform, the whole program mirror field imaging process takes less time on the premise of guaranteeing the accuracy of the result, energy analysis and mirror field dispatching on the heat absorber are facilitated, and certain practical significance is achieved.

Description

technical field

[0001] The invention relates to the field of tower-type solar thermal power systems, in particular to a GPU-based imaging method for a tower-type solar thermal power system mirror field. Background technique

[0002] The tower solar thermoelectric system uses many heliostats that independently track the sun to focus the sunlight on a heat absorber fixed on the top of the receiving tower, heat the heat transfer medium flowing through the heat absorber, and then use the high temperature medium The heat energy drives the steam turbine and generator to generate electricity. It is the lowest cost of all large-scale solar power generation technologies and has a wide range of application prospects.

[0003] The concentrating and heat-collecting subsystems in the tower solar thermal power system, including the mirror field and the heat absorber installed on the receiving tower, have always been the focus of research. Among them, the heat absorber is connected to bo...
