Of these, the most grid-connected PV practical value and theoretical significance, three-phase grid-connected photovoltaic system photovoltaic gradually become a hot topic applications. At the same time, photoelectric curtain wall technology and its proper construction the form of a combination of electricity in the city has played a significant role. In this context, this paper based on the photoelectric curtain wall for the three-phase grid-connected PV system for analysis and research.  This article first introduced the development of photovoltaic power generation system and the status quo, and the principle of photovoltaic arrays, characteristics and maximum power point tracking technology are described and compared several commonly used maximum power point tracking method. Second of three-phase grid-connected photovoltaic inverter system, part of a detailed analysis, including the photovoltaic inverter and the PWM pulse width modulation technology. At the same time, curtain wall technology for photovoltaic system analysis. Finally, based on the photoelectric curtain wall for the three-phase grid-connected PV system design of the hardware.  Keywords: photovoltaic, photovoltaic curtain wall, inverter, network. 目 录 摘 要 I Abstract II 第一章 绪 论 1 1.1 课题提出背景 1 1.1.1 光伏发电技术在国际上的发展 1 1.1.2 光伏发电技术在国内的发展 1 1.2 课题研究的目的和意义 2 1.3 课题主要研究内容 3 1.4 本章小结 3 第二章 光伏发电系统概述 4 2.1 光伏发电系统 4 2.1.1 光伏发电的工作原理 4 2.1.2 影响光伏发电的主要因素 4 2.2 光伏电池阵列 7 2.2.1 光伏电池的分类 7 2.2.2 光伏电池的工作原理 8 2.2.3 光伏电池特性 11 2.2.4 光伏阵列 14 2.3 最大功率跟踪控制技术 15 2.3.1 最大功率跟踪控制的概念 15 2.3.2 MPPT在电力电子
