[Abstract]:Solar energy as a renewable energy and clean energy, its development and application have been paid more and more attention to. However, there are still some problems in the utilization of solar energy: how to improve the efficiency of solar energy utilization, how to reduce the cost of solar power generation. How to reduce the power consumption of solar system. The purpose of this paper is to develop a low cost and low power solar mirror system, which can be used to assist photovoltaic system and photothermal system to improve the efficiency of solar energy utilization and reduce the cost. In this paper, a new kind of tracking idea-the principle of sun-oriented reflection is put forward. According to this principle, a new sun-fixing mirror system is designed. Around this system, the following works are carried out: (1) the requirement analysis of solar sun-fixed mirror technology is carried out. Through the investigation and analysis of three main solar energy utilization technologies (solar heating system, solar photovoltaic system, solar photothermal power generation system), this paper expounds the effect of sun-fixing mirror technology on improving the efficiency of solar energy utilization. The important role of cost control. (2) the principle of sun-oriented reflection is introduced, and according to this principle, the requirements of the sun-fixing mirror system are analyzed from three aspects: tracking, light path and control. The initial structural model of the helioscope system is designed, and the optimization design of the system is finally completed according to the results of the mechanical simulation and modal analysis of the structure and the simulation of the spot. (3) according to the optimized structural design model, In this paper, the various components and implementation schemes of the system are selected, and a set of sun-fixing mirror system including tracking system, optical path system and control system is developed. (4) A performance test system suitable for indoor experiments is designed and developed. The tracking characteristics of the sun-fixing mirror system are verified simply, and the jitter property of the system is simply tested. (5) A performance test system is designed and developed for external field experiments. The performance of the sun-fixed mirror system is tested in the following aspects and the analysis of the test results is carried out. The test of the influence of the threshold of 1 / 1 on the performance of the system testing the impact of rest time on the performance of the system has been carried out and the factors affecting the light spot of the system have been tested. 4 the test of system energy consumption.
