摘要：人类的发展离不开农业，而农业需要良好的灌溉技术的支持。我国农村尤其是偏远地区的农业发展主要受到灌溉技术的限制。我国灌溉方法主要是抽取地下水，传统上是采用化石能源为抽水提供能量。随着化石燃料的成本越来越高以及我国温室气体排放在国际上巨大的压力，研究新的廉价而清洁供电系统来支持灌溉已然成了必要目标。风光互补系统已在无电地区供电、室外照明、通信基站供电等有着成功的应用，利用风能和太阳能互补供电系统合理抽取地下水资源来达到对农业上的灌溉具有非常大的现实价值。92636

本文所设计的小型风光互补发电系统的风力发电和光伏发电都采用了最大功率跟踪控制以实现对风能与太阳能资源的充分利用，并且在 MATLAB 软件环境下进行了仿真分析，从电力平衡角度探究了风光互补发电装置应用在偏远农村供电的合理性，并且详细分析了其原理以及构造。仿真及成果表明，该系统在我国农业上的应用的可行性。

Abstract: the development of human beings can not be separated from agriculture, and agriculture needs the support of good irrigation technology。 The development of agriculture in China's rural areas, especially in remote areas, is mainly restricted by irrigation techniques。 In our country, the main method of irrigation is to extract groundwater。 With the increasing cost of fossil fuels and the enormous pressure on China's greenhouse gas emissions, it is necessary to study the new cheap and clean power supply system to support irrigation。 The complementary system has been in areas without electricity power supply, outdoor lighting, communication base station power supply has a successful application, the use of wind energy and solar energy complementary power supply system of groundwater resources reasonable extraction to achieve the practical value is very big on agricultural irrigation。 The wind power generation and photovoltaic power generation wind power system is designed in this paper using the maximum power tracking control to achieve full utilization of wind energy and solar energy, and simulated in the MATLAB software environment, from the perspective of the power balance of the wind light complementary power generation device used in remote rural power supply and rationality。 A detailed analysis of its principle and structure。 The feasibility of the system and its application in agriculture in china。

Key words: agriculture, irrigation, wind energy, solar energy, wind solar hybrid power generation
