【摘要】：随着环境污染的日益加重,人类环保意识的增强以及化石燃料的紧缺。对风能和太阳能的探索,引起了无数研究人员的兴趣。由于太阳能和风能具有良好的互补性,因此独立小型风光互补发电系统的研究才变的更有价值和意义。独立小型风光互补发电系统的应用对象是,电网没有覆盖到的偏远山区、孤岛以及草原上的广大牧民等。本文的研究目标是搭建光伏发电系统仿真模型和风力发电系统仿真模型,然后根据各自系统的特点,组合搭建出风光互补发电系统仿真模型,最后,通过仿真调试实现风光互补发电系统的日负荷功率输出。首先,根据风光互补发电系统的工作原理以及组成。研究了光伏阵列、发电机、风力机、变换器、控制器以及蓄电池等主要部件的原理和特性,并且搭建出了相应的仿真模型。其次,分析了太阳能和风能发电系统的最大功率点跟踪特点和原理。并且详细研究了最常见的几种太阳能和风能最大功率点跟踪控制的方法特点和原理。然后根据发电系统的数学表达式,成功地搭建仿真模型。最后,在Matlab/Simulink环境下,搭建光伏阵列、发电机、风力机、最大功率跟踪控制、PWM信号发生器、Buck型电路等模型。分别对风力发电系统以及光伏发电系统进行仿真。随后,将风、光发电系统组合,搭建出风光互补发电系统,进行仿真调试,并完成风光互补发电系统的日负荷功率输出仿真实验。紧接着对内蒙古的西苏旗和正蓝旗两个地方的全年风速变化情况和全年光照变化情况进行了分析,发现这两个地区的自然条件达到了独立小型风光互补发电系统的发电要求,可以满足单个普通家庭的用电需求。从而也验证了该仿真系统的实用性。
[Abstract]:With the worsening of environmental pollution, the increasing awareness of environmental protection and the shortage of fossil fuels. The exploration of wind and solar energy has attracted the interest of countless researchers. Because solar energy and wind energy are complementary to each other, the research of independent small-scale wind and wind complementary power generation system becomes more valuable and meaningful. The application objects of the independent small-scale wind complementary power generation system are remote mountain areas, isolated islands and pastoralists in grasslands, which are not covered by the power grid. The research goal of this paper is to build photovoltaic system simulation model and wind power system simulation model. The daily load power output of wind-wind complementary generation system is realized by simulation and debugging. First of all, according to the principle and composition of the wind and wind complementary power generation system. The principle and characteristics of photovoltaic array, generator, wind turbine, converter, controller and battery are studied, and the corresponding simulation model is built. Secondly, the characteristics and principle of maximum power point tracking in solar and wind power systems are analyzed. The characteristics and principles of the most common methods for maximum power point tracking control of solar and wind energy are studied in detail. Then, according to the mathematical expression of power generation system, the simulation model is built successfully. Finally, the models of photovoltaic array, generator, wind turbine, maximum power tracking control and PWM signal generator are built in Matlab/Simulink environment. The wind power system and photovoltaic system are simulated respectively. Then the wind and light power generation system is combined to build the wind complementary power generation system and the simulation debugging is carried out and the simulation experiment of the daily load power output of the wind and light power generation system is completed. Then, the variation of wind speed and illumination in Xisu Banner and Zhenglan Banner of Inner Mongolia are analyzed, and it is found that the natural conditions in these two regions meet the requirements of independent small-scale wind and wind complementary power generation system. Can satisfy the electricity demand of individual ordinary household. The practicability of the simulation system is also verified.
