风光互补发电系统
摘要
进入二十一世纪,人类面临着实现经济和社会可持续发展的重大挑战,而能源问题日益严重,一方面是常规能源的匮乏,另一方面石油等常规能源的开发带来一系列的问题,如环境污染、温室效应等。人类需要解决能源问题,实现可持续发展,只能依靠科技进步,大规模开发利用可再生能源和新能源。而太阳能和风能被看做是最具有代表性的新能源和可再生能源,作为这两种能源的高级利用太阳能发电和风力发电技术受到世界各国的高度重视。由于风力发电和太阳能发电系统均受到外部条件的影响,光靠独立的风力或太阳能发电系统经常会难以保证系统供电的连续性和稳定性,因此,在采用风光互补的混合发电系统来进行相互补充,实现连续、稳定地供电。风光互补发电以其独特优势成为新能源研究的热点之一。本文针对风光互补发电系统设计了一套小型模拟装置,包括太阳能电池模拟,用直流电机对风机的模拟和交错并联Buck-Boost蓄电池充电主电路,并对交错并联Buck-Boost电路和交错并联Cuk斩波电路进行了研究、仿真,以及进行了模拟风机装置的调试。系统控制全部采用Freescale公司的56F8013 DSP控制实现,给出了各部分流程图。对于软硬件的关键问题还给出了相应解决方案。

Wind & Solar Hybrid Generating System
ABSTRACT
Entering the 21st century, human beings are facing to realize the sustainable development of economy and society, and energy problem es more and more serious, on the one hand,
conventional energy is serious short on the other hand, the development of oil and other conventional energy brings a series of problems, such as the environmental pollution, the greenhouse effect and so on. Only by relying on the progress of science and technology and the large-scale exploitation and utilization of renewable energy and new energy can human solve the problem of energy, and realize the sustainable development. And solar and wind power are considered the most representative of new and renewable energy, The power technology of solar energy and wind attrack world’s attention. Because of wind power and solar power system under external conditions, and only by independent wind or solar power systems often hard to ensure the continuity and consistency of power system therefore, using hybrid power system plementary scenery plement each other, realize the continuous, stable power supply. Wind-plementary with its unique advantages e one of new energy research hotspots. Aiming at wind-plementary this article design a small device, including solar cells in dc motor, the simulation and interlacing of fan parallel Buck - hee, and main circuit batteries to Buck staggered shunt circuit and int
