【摘要】：能源短缺问题和环境污染问题的日益严重,促使清洁能源得到大力发展。太阳能作为一种清洁无污染的可大规模开采利用的可再生能源具有宽广的应用前景。而城市土地资源的稀缺,让建筑光伏一体化得到广泛应用。建筑光伏发电并网将太阳能发电技术融入于建筑体,是一种高效利用太阳能的手段,引起了很多人的关注与研究。对建筑光伏发电并网系统的深入探究是一个既具有研究意义和指导意义的课题。本次研究课题主要在建筑光伏发电并网系统及其相关的技术方面进行了探讨。 论文首先分析了光伏发电的发展现状及应用前景,简要地介绍了课题所依托的项目情况,以及光伏发电的技术特点及项目建设目标。 光伏发电并网系统主要由太阳能电池组件、并网逆变器、电气接入系统、监测系统等部分组成。论文详细分析了光伏发电并网系统的一二次设备的选型方案,包括光伏系统配置、直流接口设备选型、并网逆变器选型,以及保护装置、通信系统和计量关口的设计要求。 根据所建立的光伏发电并网系统,论文提出了系统运行维护方案,以保证系统能够安全可靠稳定的运行。 最后,论文对项目所产生的环境影响和推广价值进行了分析,进行了光伏发电转换效率和发电量计算分析,提出了建筑光伏发电项目存在的潜在风险和风险控制措施。
[Abstract]:The problem of energy shortage and environmental pollution is becoming more and more serious, which promotes the development of clean energy. As a clean and non-polluting renewable energy, solar energy has a broad application prospect. With the scarcity of urban land resources, building photovoltaic integration is widely used. Building photovoltaic power grid will integrate solar power technology into the building body, which is a means of efficient use of solar energy, which has attracted many people's attention and research. The research of building photovoltaic grid-connected system is an important and instructive subject. This paper mainly discusses the grid-connected system of building photovoltaic power generation and its related technology. Firstly, the paper analyzes the development status and application prospect of photovoltaic power generation, briefly introduces the project situation, the technical characteristics and project construction objectives of photovoltaic power generation. Photovoltaic grid-connected system is mainly composed of solar cell module, grid-connected inverter, electrical access system, monitoring system and so on. This paper analyzes the primary and secondary equipment selection scheme of PV power grid connection system in detail, including photovoltaic system configuration, DC interface equipment selection, grid-connected inverter selection, as well as the design requirements of protection device, communication system and metering gate. According to the grid-connected photovoltaic system, the system operation and maintenance scheme is proposed to ensure the system can run safely, reliably and stably. Finally, the paper analyzes the environmental impact and promotion value of the project, analyzes the conversion efficiency of photovoltaic power generation and power generation calculation, and puts forward the potential risks and risk control measures of the building photovoltaic power generation project.
