【摘要】:風(fēng)力發(fā)電是一種靈活機(jī)動(dòng)、安全可靠的發(fā)電方式,但風(fēng)能的波動(dòng)、隨機(jī)性,使得風(fēng)電并網(wǎng)的應(yīng)用受阻,導(dǎo)致棄風(fēng)限電現(xiàn)象嚴(yán)重。為避免這類(lèi)現(xiàn)象繼續(xù)惡化,國(guó)內(nèi)專(zhuān)家提出了非并網(wǎng)風(fēng)電應(yīng)用,即將風(fēng)能直接應(yīng)用于高耗能直流負(fù)載,不僅可平抑風(fēng)電對(duì)電網(wǎng)的沖擊,也能提升風(fēng)電資源的利用率,使風(fēng)電成本降低。開(kāi)關(guān)磁阻發(fā)電機(jī)(Switched Reluctance Generator,簡(jiǎn)稱(chēng)SRG)作為一種新型特種發(fā)電機(jī),具有成本低、構(gòu)造簡(jiǎn)單、適應(yīng)惡劣環(huán)境等特點(diǎn),在風(fēng)力發(fā)電領(lǐng)域極具潛力,相應(yīng)的研究也越來(lái)越多。若將SRG用于為高耗能直流負(fù)載供電,無(wú)需逆變單元,可簡(jiǎn)化風(fēng)電設(shè)備,推動(dòng)風(fēng)電產(chǎn)業(yè)快速發(fā)展,帶來(lái)很大的經(jīng)濟(jì)效益。本文首先介紹了開(kāi)關(guān)磁阻發(fā)電機(jī)的發(fā)展現(xiàn)狀,分析了三種高耗能直流負(fù)載特性,提出將開(kāi)關(guān)磁阻風(fēng)力發(fā)電機(jī)用于為此類(lèi)負(fù)載供電,其次針對(duì)此類(lèi)負(fù)載特性確定發(fā)電機(jī)的額定參數(shù)并對(duì)電機(jī)本體進(jìn)行了初步設(shè)計(jì),以提高SRG發(fā)電效率為目的,通過(guò)MathCAD計(jì)算軟件和Ansoft Maxwell 16.0有限元仿真,對(duì)電機(jī)尺寸參數(shù)進(jìn)行了計(jì)算和優(yōu)化,以及開(kāi)關(guān)磁阻發(fā)電機(jī)內(nèi)部電磁場(chǎng)的有限元分析。最后基于Matlab軟件建立了風(fēng)力機(jī)模型,研究風(fēng)力機(jī)的功率特性;針對(duì)開(kāi)關(guān)磁阻風(fēng)力發(fā)電機(jī)及其系統(tǒng)建模,研究最大風(fēng)能跟蹤的幾種常規(guī)控制方法,建立基于直流負(fù)載的開(kāi)關(guān)磁阻風(fēng)力發(fā)電系統(tǒng)的仿真模型,結(jié)果表明開(kāi)關(guān)磁阻風(fēng)力發(fā)電機(jī)滿(mǎn)足此類(lèi)負(fù)載的供電要求以及該發(fā)電系統(tǒng)的可行性。
[Abstract]:Wind power generation is a flexible, safe and reliable way, but the wind fluctuation and randomness, makes the application of wind power grid is blocked, resulting in abandoned wind power rationing phenomenon is serious. In order to avoid this kind of phenomenon continues to deteriorate, domestic experts put forward the application of non grid connected wind power, wind energy is directly applied to high energy DC load that not only can stabilize the impact of wind power on the grid, the use of wind power can also increase the rate of resources, the wind power cost is reduced. The switched reluctance generator (Switched Reluctance Generator, referred to as SRG) as a new special generator, has low cost, simple structure, adapt to the harsh environment, in the field of wind power generation very the potential, the corresponding research is more and more. If the SRG is used to load power supply for high energy consumption without DC inverter unit, can simplify the wind power equipment, to promote the rapid development of wind power industry, bring great economic benefits. This paper first introduces the development of switched reluctance generator, analyzed three kinds of high energy DC load characteristics, the Switched Reluctance Wind power generator for the load power supply, secondly, such load characteristics determine the rated parameters of the generator and the motor in the preliminary design, in order to improve the efficiency of power generation for the purpose of SRG, calculated by MathCAD software Ansoft and Maxwell 16 finite element simulation, calculation and optimization of the size of the motor parameters, and the finite element analysis of electromagnetic switch reluctance generator. Finally, based on the Matlab software of the wind turbine model is established, the power characteristics of wind turbine; modeling for switched reluctance wind generator and its system, study the maximum wind energy tracking severalconventional control method and to establish the simulation model of switched reluctance generator system based on DC load, the results show that the switch reluctance Wind turbines meet the power supply requirements of this kind of load and the feasibility of the power generation system.
