摘要
随着我国经济的飞速发展,移动通信在我国的经济发展中越来越体现着非常重要的作用。电源是移动通信的基础。随着电信事业的飞速发展,通信局(或基站)的分布范围也越来越广,大量局站地处少电或无电地区,而往往这些地区的太阳能资源相当丰富,因此大力推广太阳能供电系统具有很好的社会效益和经济效益。
本文首先研究了太阳能供电系统的组成、原理、特性,以及太阳能供电系统的工作模式；其次对太阳能供电系统的控制器原理进行了分析比较,针对系统的关键部件——系统控制器进行理论分析,并提出了基于INC算法的带有MPPT功能的太阳能供电系统控制器的设计。文中从原理上将两种太阳能供电系统控制器进行了对比。最后,通过实验的方式将本文所设计的太阳能控制器和现有的蓄电池稳压型太阳能控制器工作效率进行了比较。通过具体的实验数据验证了基于INC算法的MPPT太阳能控制器的高效性和可行性。通过本课题,希望为今后的基站用太阳能供电系统的应用提供有效的指导意见。
With the rapid development of our country's economy, mobile communications plays a more and more important role in Chinese economic development. Power is the base of mobile communications. With the rapid development of the telecommunications industry, communications bureaus (or base stations) are more widely spread, a large number of Board Stations are located in areas where electricity is insufficient or none, often, the solar energy resources are very rich in these areas. So, the promotion of the solar energy power supply system will bring great social benefits and economic benefits.
Firstly, the paper studies the solar power supply system's composition, principles, characteristics and working model. Secondly, analyzing and comparing the principles of the controller of the solar power supply system. Theoretically analyzing the System Controller, the key components of the system, studying the MPPT's track strategy based on Based on INC-algorithm and its design method. We compare the two kinds of solar power supply controllers from principle. Finally, search the characteristics of solar power supply system through this test. Through the data, we confirm that controller with MPPT's track strategy based on Based on INC-algorithm is feasible and efficient. As different solar energy resources, experimenting and studying through the application and research in practice, as well as analyzing the economy. The applied research is of remarkable significance for optimizing the construct of the small base station's power supply system. Through this issue, we wish provide effective guidance for the future solar-powered base station systems.
