Development Of Control And 3D Display Software For Space Solar Power Generation Demonstration System Software Development

With the advent of the fourth industrial revolution,the existing non-renewable resources on the earth have been heavily explored and consumed,limited fossil energy are facing depietion,and the problem of climate and environmental degradation is becoming increasing serious.Therefore,the search for new renewable clean energy has become an urgent problem for human economic and industrial development.As one of the representatives of renewable clean energy,the huge storage capacity of solar energy makes it contains unlimited potential for development,and it is widely valued by various countries.Researchers believe that space solar power station(SSPS)can be established in space to collect solar energy and achieve efficient use of solar energy.This program is considered to be one of the most effective ways to solve the current energy crisis.To confirm the feasibility of the space solar power system,the project team further proposed the SSPS-OMEGA scheme,which uses OMEGA spherical concentrators to collect light energy in the air and then transmit it back to the ground in the form of microwave.For the space solar power station demonstration system,the main research work of this paper is as follows.For starters,this paper presents the general architecture of the space solar ground demonstration system and the key technologies to be used.The demonstration system includes the light energy collection part,the air transmission part and the ground receiving part.The light energy collection part mainly consists of a concentrator mechanism,a photovoltaic cell collection array and a three-cable support structure;the air part is composed of a transmitting antenna and an AB axis platform;the ground part is mainly refers to microwave receiving field.The technologies used in this thesis mainly include solar synchronization tracking technology,trajectory planning algorithm,virtual reality and 3D modeling technology and C# language programming.Next,by analyzing the law of solar motion,based on the use of solar motion trajectory tracking technology,two detection coordinate systems are compared and selected optimally,and the approximate calculation models of solar altitude angle and azimuth angle are obtained by using Bourges declination angle algorithm and Lamm time angle time difference algorithm.By establishing the Newton-Euler dynamics equations,the trajectory planning of the concentrator mechanism following the transformation of sun’s position was completed,which laid the foundation for the precise control of the system.Afterwards,according to the project requirements,a clear design objective is proposed for the ground demonstration system,and the sub-module design idea is adopted for functional analysis.The program development work of the system control software is completed using Visual Studio development platform according to the requirements of each module.The computer-controlled servo motor communication is realized through the motion control card,and the solar motion trajectory is calculated by combining the apparent solar motion trajectory method.The sun following function of the concentrator mechanism is realized together with the cable system support control module and AB axis control module,and the transmitting antenna beam control pointing and microwave field intensity receiving module are completed to ensure the transmission efficiency of the demonstration system.In addition,the three-dimensional modeling implementation of the demonstration system is carried out in combination with virtual reality technology,the power generation process of the system is fully demonstrated,and the difficulties and solutions arising in the implementation process are explained.Finally,through the simulation analysis and experimental test,the results show that the research of tracking solar motion trajectory proposed in this paper is feasible and accurate.The designed space solar power station demonstration system control software and virtual reality-based 3D system simulation have completed the design of the required functions for the project,and laid a solid foundation for the subsequent progress of the project.
