摘要:現(xiàn)如今能源的短缺和環(huán)境方面的問題越來越受到人們的關(guān)注,可再生并且清潔無污染的能源越來越受到人們的青睞。風(fēng)能是一種十分清潔的可再生的能源并且其儲量非常的豐富,因而風(fēng)力發(fā)電技術(shù)受到各國的高度重視。本文主要對風(fēng)力發(fā)電的背景以及現(xiàn)狀作簡要介紹,同時對交流勵磁變速恒頻技術(shù)進(jìn)行一定深度的研究,并且建立了交流勵磁雙饋電機(jī)的數(shù)學(xué)模型。再根據(jù)風(fēng)力發(fā)電系統(tǒng)的組成,將風(fēng)力發(fā)電機(jī)組拆解為風(fēng)速、風(fēng)力機(jī)、傳動系統(tǒng)以及發(fā)電機(jī)等子系統(tǒng),并對這些子系統(tǒng)進(jìn)行模型建立,最后運(yùn)用MATLAB/simulink軟件對建立的模型進(jìn)行仿真。文章最后對于變速風(fēng)力發(fā)電機(jī)組這一主流發(fā)電系統(tǒng)的控制部分做了一些簡要的研究說明。 關(guān)鍵詞 風(fēng)力發(fā)電系統(tǒng);交流勵磁變速恒頻;雙饋電機(jī);數(shù)學(xué)建模;matlab仿真
Abstract:Nowadays energy shortage and environmental issues have been paid attention by more and more people,renewable and clean pollution-free energy more and more get the favour of people. Wind energy is a clean renewable energy and its reserves are very rich,thus wind power technology attaches great importance to by the countries.This article mainly about a brief introduction of the background and status quo of wind power,For the ac excitation variable speed constant frequency technology research of certain depth,and established the mathematical model of ac excitation doubly-fed motor.According to the composition of wind power generation system,the wind generating set apart for wind speed,wind turbine,drive system and generator subsystem,and carries on the model of these subsystems,by using the software of MATLAB/simulink for simulation model.Finally the mainstream for variable speed wind turbine power generation system control part made some brief research suggests.
