毕业论文-太阳能光伏电池最大功率点跟踪系统 摘要 随着世界经济的迅速发展,对能源的需求越来越大,地球化石资源的大量开采与消耗,使石油、煤炭等自然资源日趋短缺,同时也给环境造成了严重污染。因此大力发展太阳能成为了当务之急。 光伏电池的输出特性具有强烈的非线性,且受外界环境因素影响大,所以,如何有效的利用、提高太阳能转换效率,成为太阳能利用中一个迫切需要解决的问题。 关键词：控制器；光伏电池；最大功率点跟踪；电导增量法；PSCAD仿真 Abstract With the rapid development of the world economy, increasing demand for energy, ‘ mass-extraction and consumption of fossil resources of the Earth, the increasing shortage of natural resources such as oil, coal, and also caused serious pollution to the environment. Devoting major efforts to developing solar energy has become a priority. Output characteristics of photovoltaic cells with strong nonlinearity, and under the influence of external environmental factors, therefore, how to effectively use, improve energy efficiency, an urgent need to address the problems in the utilization of solar energy. This article by power electronics and control technology to achieve maximum power point tracking for photovoltaic power generation (MPPT), maximum power point tracking with conductance increment method in this article. Photovoltaic power generation systems for the study, main goal is to maximize solar, photovoltaic power generation system of theoretical and experimental research on efficiency optimization. This article has to be based on simulation experiment of PSCAD. Experiment results show that the good implementation of the simulation of solar cells, as well as in the case of solar energy input light intensity changes, can be a very good maximum power point tracking solar. Key words: controller, photovoltaic cell; maximum power point tracking; conductance increment method; PSCAD simulation 目 录 1 绪论................................................1 1.1 课题研究的背景................................. 1 1.2 课题研究的意义...............................4 1.3 课题研究的 总结...............................................35 参考文献...............................................36 致谢...................................................37 1绪 论 1.1课题研究的背景 目前世界上的能源消耗几乎全
