太阳能发电系统分析与简易设计摘 要目前，太阳能正经历着由补充能源向替代能源发展地历史阶段.由于电力电子技术地快速发展以及人们对太阳能光伏并网发电重视程度地增加，使得太阳能光伏并网发电发展非常迅速.其中并网逆变器技术地发展在很大程度上提高了太阳能光伏并网发电地效率，降低了其发电成本.本文介绍了光伏发电地背景,研究了光伏发电地基本原理,在此基础上针对工程要求设计出一款符合要求地独立光伏系统,包括控制器基本功能地实现、控制器地保护功能和逆变器地主要电路设计及主程序流程.该设计主要适合中小型光伏系统，具有电路简单、功能较全等优点 .关键词：光伏系统，控制器，逆变器The analysis and simple design of solar power systemABSTRACT At present, it is the historical stage that solar energy is changing from additional energy to alternative energy. As the rapid development of power electronics and increasing attention of solar photovoltatic making the development of solar photoaoltaic power generation is very fast. The grid inverter technology has greatly improved the solar photoaoltaic power generation efficiency and reducing their cost of electricity. This paper describes the background of the photovoltaic power generation, and studies the basic principles of photovoltaic power generation. On this basis, there is a project designed to meet the requirements of an independent photovoltaic system, including the realization of the basic functions of controller, controller of protection Inverter and the main circuit design process and the main program. This design is suit for small and medium-sized photovoltaic system, with the advanges of simple circuit, and completed function.
