I 光伏瓦光伏系统的性能研究

摘 要

近年来由于人们对能源、环境问题的日益关注，传统的燃料能源正在一天天减少，与此同时全球还有约20亿人得不到正常的能源供应。这个时候，人们把目光投向了可再生能源，希望可再生能源能够改变人类的能源结构，维持长远的可持续发展。其中太阳能以其独有的优势成为人们关注的焦点。丰富的太阳辐射能，是取之不尽用之不竭、无污染、廉价的能源。本文主要研究。本文主要研究家用光伏陶瓷瓦屋顶系统，它有着相当广泛的应用。本文对该家用光伏系统在生活中的实际利用价值进行深入研究，为了进一步提高系统的性能，实现系统的优化及可靠运行，本文针对日常的光伏瓦测定相关实验数据。这对于国家正大力发展的西部太阳能资源开发来说是具有现实意义的。

本文首先介绍了太阳能光伏发电系统的原理和构成,以及民用建筑中几种常见的光伏系统的浅谈.并详细分析了一套家用太阳能光伏发电系统，包括光伏瓦的模型及输出特性,以及该系统的操作安全注意事项、特点和用途、系统运用介绍。

其次,基于对上述资料的分析,提出了相对完整的家用陶瓷瓦光伏系统设计、实验样机和实验参数。结合应用物理学和光伏材料相关理论进行分析研究，制定光伏系统的整体控制方案，充分利用现有的实验条件测定实验数据，对家用光伏陶瓷瓦屋顶系统进行模拟和实验,研究光伏瓦日常发电的性能，验证和解决光伏材料的相关技术问题。

研究表明：该系统很好的实现了本文提出的实验方案所应完成的各项功能。且光控太阳能照明系统是光伏应用的重要领域，这类光伏系统的工作条件非常苛刻，必须根据其特点，进行仔细的系统优化设计，才能确保其长期稳定地工作。由于系统每天工作的时间长短不一样．在光伏系统谩计时，可以根据当地不同月份的日落和日出之间的无日照小时数减1．来作为光控太阳能照明系统的工作时间，眦确定其各月不同的负载日耗电量。决定蓄电池维持天数时，也是以最大的日耗电量为依据。光伏方阵的最佳倾角也要大于一般的独立光伏系统。

最后给出了实验结果，证明光伏瓦光伏系统设计的合理性,以及能很好应用于各地电力资源匮乏的区域。

II Performance study of the photovoltaic tile -photovoltaic system

ABSTRACT

In recent years as people have problems of the energy, the environment more and more attention, the traditional fuel energy is to reduce day by day, and at the same time around the world, about 2 billion people do not have the normal energy supply. This time, the people are turning to renewable energy, hope renewable energy can change the human energy structure, maintain long-term sustainable development. Among them with its unique advantage of solar energy is the focus of attention. Rich solar radiation, is the inexhaustible, no pollution, cheap energy. This paper mainly studies. This paper makes a study of the ceramic tile roof photovoltaic (pv) systems, it has a wide range of applications. This paper analyzes the photovoltaic (pv) systems in the life of the actual value of further research, in order to further improve the performance of the system, realize the optimization of system and reliable operation, this article in view of the daily photovoltaic tile determination related experimental data. This country is developing for the western solar energy resources for development is realistic.

This paper first introduced the solar photovoltaic power generation system principle and structure, and civil building in several common photovoltaic system on. And detailed analysis of a home solar photovoltaic power generation systems, including photovoltaic watts model and output characteristics, and the operation of the system safety precautions, characteristics and use, the system is introduced, using the maintenance and repair.

Secondly, based on the analysis of the above information, and puts forward the relative complete ceramic tile photovoltaic system of household design, the experimental prototype and experimental parameters. Combined with applied physics and photovoltaic material related theory analysis, make the whole photovoltaic system control plan, make full use of the present condition of experiment test data, the ceramic tile roof photovoltaic (pv) systems for simulation and experiment, the photovoltaic power generation, the performance of the daily, validation and solve the photovoltaic material related technical problems.

Research shows that the system is very good realized the proposed experiment scheme should make each function. And electric solar lighting system is an important

III field pv-tech application, this kind of photovoltaic system working conditions is very strict, must according to its characteristic, the system optimization design was carefully, to ensure that its long-term stability to work. Because the system work every day the length of time is not the same. In photovoltaic system Man timing, and may, according to the local different months of sunrise and sunset between the hours of sunshine without reducing 1. As a solar lighting system to control the working time of the, angular determine its was produced different load, power consumption. Decided to keep the battery number, which also is the biggest day for the basis for power consumption. The best Angle photovoltaic square than general also independent photovoltaic system.

Finally the experimental results show that photovoltaic (pv), the rationality of the design of the system, and can be used in electric power resources all over the lack of area.

KEY WORDS: Photovoltaic systems, Lighting system, Photovoltaic tile, Battery discharge,Performance study
