摘 要
随着化石能源消耗的不断增长,世界性的能源危机和环境问题已经日益突出。在绿色可再生能源中,太阳能凭借其存储量无限、清洁安全以及易于获取等独特优点而受到了世界各国科研领域的普遍关注,太阳能光伏发电技术的应用更是普遍关注的焦点。我国化石能源相对贫乏而能源消耗量巨大,因此展开对太阳能光伏发电技术的研究和应用上的普及对我国未来的经济发展有着非常重要的战略意义。一套基本的光伏发电系统一般由太阳能电池板、蓄电池、直流控制系统和逆变器组成。其中,直流控制系统是光伏发电系统的核心部分。
Abstract
With the costant growing consumption of fossil energy, global energy crisis and environmental problems have become more and more acute. Among various green renewable energy resources, solar energy has drawn the attention from the scientific circles of various countries due to its unique advantages such as bountless storage content, cleaness and safety, and easiness to obtain. In particular, the application of solar photovoltaic technology has become a universal focus. China has relatively scarce fossil energy resources while a huge energy consumption. Therefore, the research and application of solar photovoltaic technology has important strategic meaning for the future economic development of China. A basic solar photovoltaic system is generally composed of solar panels, storage batteries, DC (direct current) control system and inverters, among which, DC control system is the central part of the solar photovoltaic system.
本课题的主要内容包括太阳能光伏发电系统的发展和应用,太阳能光伏发电系统的分类,太阳能光伏电池和蓄电池的选型,直流控制系统的设计,太阳能电池最大功率点的跟踪设置,逆变器容量的确定及电路设计,三相变压器及交流配电系统的设置。
