摘 要化石能源的不断减少,成了人类共同面对的世界性难题,近年来更 出现了前所未有的危机。除了储藏量越来越少以外,更重要的是严重污 染了环境,使得人们更加关注、思考社会发展动力的来源。不少国家有 一个明显的战略改变——鼓励开发新能源,而风能作为一种可再生能源, 更是人类开发和利用的重点。
本文针对某四人间宿舍的用电需求,在掌握风力发电组、液流储能 电池、海水淡化装置等主要设备类型、基本原理的基础上,通过设计计 算,选择了相应的设备,建立了风能发电及液流储能电池的海水淡化系 统的仿真数学模型。采用 Matlab/simulink 软件,搭建了整个系统的仿 真分析模型。仿真结果表明,本文建立的系统能够稳定运行,能满足用户 用电用水的需要。84818

Abstract In recent years, oil, coal and natural gas based petrochemical energy appeared an unprecedented crisis, in addition to its reserves will continue to reduce, the more importance is the serious pollution of the environment, caused the people of paying wide attention and consideration to future social development power source。Energy strategy in many countries has an obvious change: to encourage people to develop new energy sources--- wind energy as a renewable energy, is the focus of human development and utilization。
To master the wind power group, fluid reservoir to battery, sea water desalination device, main equipment types,based on the basic principle, according to a four dormitory electricity demand, select the corresponding equipment。In Matlab / Simulink to establish the established wind power generation and liquid flow storage energy battery of seawater desalination system simulation model, the model by the wind machine, permanent magnet motor, liquid flow storage energy battery,seawater desalination analysis of the mathematical model of the device to realize the whole system model is built。The simulation results show that the system can run stably, and can meet the needs of the users。
Key Word: wind power generation;Liquid energy storage battery;Sea water desalination;Simulation
