PAGE 20 基于风光互补的发电系统设计 摘 要 随着社会经济的飞速发展，人类的生产生活对传统能源的需求日益增加。与此同时，大量使用传统能源对地球的生态环境造成了严重的破坏，所以人们把更多的目光聚焦于可再生能源上。在常见的可再生能源中，风能和太阳能则是我们最广泛使用的。由于风能和太阳能在资源条件和技术应用上具有互补性,所以利用风光互补的发电系统可以有效的解决能源紧缺和环境污染的问题，并且在电力供应严重不足的偏远地区能给当地居民带来巨大的生产生活便利，带动当地的经济发展。 本文对于风光互补发电系统的分析中，研究出风能及太阳能互补发电系统的结构，详细分析得出系统的发电、变电、储能及负载损耗等各个功能模块的工作流程，确定了对风力发电。光伏发电以及蓄电池充放电的控制策略，在计算机控制技术基础上，提供风光互补的资源最大利用率的可行性分析。以单片机为核心的控制芯片，研究各功能电路的实现方法。对系统能量的最大转化率和利用率进行研究和分析，通过分析得出的功能参数基于MATLAB/Multisim进行建模和仿真。在仿真结果分析表明，该系统设计的是有效可行的。 关键词：风光互补 控制策略 系统设计 Design of Power Generation System Based on Wind-Solar Complement Abstract With the rapid development of social economy, the demand for traditional energy in the production and life of human beings is increasing. At the same time, the extensive use of traditional energy sources has caused severe damage to the earths ecological environment, so people have focused more on renewable energy. Among the common renewable energy sources, wind energy and solar energy are our most widely used. Because wind and solar energy are complementary in terms of resource conditions and technology applications, the use of wind-solar complementary power generation systems can effectively solve the problem of energy shortage and environmental pollution, and can bring huge losses to local residents in remote areas with severe power shortage Convenient production and living, driving local economic development. In the analysis of the wind-solar hybrid power generation system in this paper, the structure of the wind and solar complementary power generation system is studied, and the work flow of each functional module such as power generation, substation, energy storage and load loss of the system is analyzed in detail, and the wind power generation is determined. . The control strategy of photovoltaic power generation and battery charge and discharge, based on computer control technology, provides a feasibility analysis of the maximum utilization of wind and solar resources.
