The Research and Design of Wind-solar Hybrid Power System above the Residential Building

居民楼顶风电光综合系统在节约传统能源中起着重要作用,因此对其研究有着极大的经济和社会价值。文中系统中对硬件和软件进行初步设计,首先探讨风能和太阳能输出部分,接着介绍系统的各部分组成,包括能量管理部分,环境数据采集部分。每个组件的运行原理和工作特点包含在这个系统中,整个系统分为风力发电系统、太阳能发电系统、电池储能系统,还有数据采集监测系统。对蓄电池部分,采用数字电压表对其进行时时监测,反馈后可对充电进行控制。另外,能量管理部分采用模糊控制算法对系统能量进行管理。数据采集监测系统主要完成对光照强度、风速风向、温度的数据采集,用DS18B20测量环境温度,并在液晶显示器1602上显示。对于每个部分,从设计元素开始,然后到主要控制技术的实现方法再到硬件、软件电路的设计都进行研究。居民楼顶风电光综合系统的研究具有很重要的现实意义。

The wind-solar hybrid power system above the residential building plays an important role in saving traditional energy,therefore the research of wind-solar hybrid power system is much valuable for economy and society. In this paper,the hardware and software of the wind-solar hybrid power system is designed. Firstly complementary characteristics between wind energy and solar energy are discussed,and running structure of undispatchable wind-solar hybrid power system,which contains wind turbine generator,photovoltaic array,inverter and electro-load,is analyzed. Then the running principle and the working characteristics of each component contained in this system are analyzed. In this section,the whole system is divided into wind power system,solar power system and battery energy storage system by their different functions. For the battery part,we use the digital voltmeter to constantly monitor the electric voltage of the battery and feedback the data to charging control system. The collection and monitoring system mainly complete the task of data acquisition about the light intensity,wind speed and direction,temperature. We focus on using DS18B20 to measure the temperature,and the current temperature is shown through the Liquid Crystal 1602. For each part,design elements are started with,then main control technique,achieving methods,hardware and software design are researched. The research demonstrates that the wind-solar hybrid power system has great practical signifinance in daily life.
