【摘要】：随着全球环境污染和能源危机的加剧,开发一种有效、合理、无污染、能保护生态环境的新能源成为当前亟需解决的问题。由于环境发展需要,利用可再生资源进行能源的开发迫在眉睫,风能和太阳能成为首选,主要原因一是由于二者对于生态环境影响小,二是两者的工作特性具有良好互补性能,同时从保护环境角度出发,二者的有机结合可以实现不间断循环利用无污染,这对于解决实际能源问题具有重要意义。风光互补外送发电系统是在风能和太阳能各自优点的基础上进行搭建完成的系统,它主要利用两者在地域以及时间上的互补性来保证电能的稳定供应。本文首先阐述了风力发电系统和光伏发电系统的组成结构和工作原理,并分别搭建了风力发电系统和光伏发电系统的仿真模型,通过仿真模型对两个独立的新能源发电系统电压稳定性进行研究,探究其独立发电时的优势和不足。随后搭建了由二者构成的统一有机体——风光互补发电系统。通过对影响风光互补发供电系统的物理量进行模拟仿真,有效地观测了系统的运行特性,并对单因素和多因素如何影响系统电压稳定性进行了分析和研究,能够从理论上指导风光互补发电系统的建立和运行。
[Abstract]:With the aggravation of global environmental pollution and energy crisis, the development of a new energy source which is effective, reasonable, pollution-free and can protect the ecological environment has become a problem that needs to be solved urgently. The use of renewable resources for the development of energy is imminent, wind and solar energy become the first choice, the main reason is that the two have little impact on the ecological environment, the other is that the working characteristics of the two have good complementary performance. At the same time, from the point of view of environmental protection, the organic combination of the two can realize uninterrupted recycling and non-pollution. This is of great significance to solve the practical energy problem. The wind and solar power generation system is built on the basis of wind energy and solar energy. It mainly utilizes the complementarity of the two in the region and time to ensure the stable supply of electricity. Firstly, this paper describes the composition structure and working principle of wind power system and photovoltaic power system. The simulation models of wind power system and photovoltaic system are built, and the voltage stability of two independent new energy generation systems is studied by simulation model. Explore the advantages and disadvantages of its independent generation. Then set up a unified organic-wind-wind complementary power generation system composed of the two. Through the simulation of the physical quantities which affect the wind and wind complementary power generation and power supply system. The operating characteristics of the system are observed effectively, and how single and multiple factors affect the voltage stability of the system are analyzed and studied, which can guide the establishment and operation of the wind and solar complementary generation system theoretically.
