【摘要】：隨著環(huán)境污染的日益加重,人類環(huán)保意識的增強(qiáng)以及化石燃料的緊缺。對風(fēng)能和太陽能的探索,引起了無數(shù)研究人員的興趣。由于太陽能和風(fēng)能具有良好的互補(bǔ)性,因此獨(dú)立小型風(fēng)光互補(bǔ)發(fā)電系統(tǒng)的研究才變的更有價值和意義。獨(dú)立小型風(fēng)光互補(bǔ)發(fā)電系統(tǒng)的應(yīng)用對象是,電網(wǎng)沒有覆蓋到的偏遠(yuǎn)山區(qū)、孤島以及草原上的廣大牧民等。本文的研究目標(biāo)是搭建光伏發(fā)電系統(tǒng)仿真模型和風(fēng)力發(fā)電系統(tǒng)仿真模型,然后根據(jù)各自系統(tǒng)的特點(diǎn),組合搭建出風(fēng)光互補(bǔ)發(fā)電系統(tǒng)仿真模型,最后,通過仿真調(diào)試實(shí)現(xiàn)風(fēng)光互補(bǔ)發(fā)電系統(tǒng)的日負(fù)荷功率輸出。首先,根據(jù)風(fēng)光互補(bǔ)發(fā)電系統(tǒng)的工作原理以及組成。研究了光伏陣列、發(fā)電機(jī)、風(fēng)力機(jī)、變換器、控制器以及蓄電池等主要部件的原理和特性,并且搭建出了相應(yīng)的仿真模型。其次,分析了太陽能和風(fēng)能發(fā)電系統(tǒng)的最大功率點(diǎn)跟蹤特點(diǎn)和原理。并且詳細(xì)研究了最常見的幾種太陽能和風(fēng)能最大功率點(diǎn)跟蹤控制的方法特點(diǎn)和原理。然后根據(jù)發(fā)電系統(tǒng)的數(shù)學(xué)表達(dá)式,成功地搭建仿真模型。最后,在Matlab/Simulink環(huán)境下,搭建光伏陣列、發(fā)電機(jī)、風(fēng)力機(jī)、最大功率跟蹤控制、PWM信號發(fā)生器、Buck型電路等模型。分別對風(fēng)力發(fā)電系統(tǒng)以及光伏發(fā)電系統(tǒng)進(jìn)行仿真。隨后,將風(fēng)、光發(fā)電系統(tǒng)組合,搭建出風(fēng)光互補(bǔ)發(fā)電系統(tǒng),進(jìn)行仿真調(diào)試,并完成風(fēng)光互補(bǔ)發(fā)電系統(tǒng)的日負(fù)荷功率輸出仿真實(shí)驗(yàn)。緊接著對內(nèi)蒙古的西蘇旗和正藍(lán)旗兩個地方的全年風(fēng)速變化情況和全年光照變化情況進(jìn)行了分析,發(fā)現(xiàn)這兩個地區(qū)的自然條件達(dá)到了獨(dú)立小型風(fēng)光互補(bǔ)發(fā)電系統(tǒng)的發(fā)電要求,可以滿足單個普通家庭的用電需求。從而也驗(yàn)證了該仿真系統(tǒng)的實(shí)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.
