【摘要】：飛輪儲能技術(shù)是一種新型的能量存儲技術(shù)。飛輪儲能系統(tǒng)具有比能量高、比功率大、體積小、充電快、壽命長、無任何廢氣廢料污染等優(yōu)點。特別是隨著真空技術(shù)、復(fù)合材料技術(shù)、磁懸浮技術(shù)的發(fā)展,使這一新型儲能裝置的開發(fā)和應(yīng)用成為可能,有著良好的發(fā)展前景。 飛輪儲能的關(guān)鍵技術(shù)之一就是其支承技術(shù),飛輪的支承系統(tǒng)不但要能支承飛輪轉(zhuǎn)子,使其可靠穩(wěn)定的運行,并且需要盡量縮小整個飛輪轉(zhuǎn)子的尺寸、降低由于支承引起的能量損耗。本文就飛輪轉(zhuǎn)子的支承進(jìn)行探索研究。 本文介紹了飛輪儲能系統(tǒng)的基本原理與結(jié)構(gòu),總結(jié)了目前國內(nèi)外飛輪儲能技術(shù)研究的現(xiàn)狀,重點分析了國內(nèi)外飛輪儲能支承的研究成果以及存在的問題。 本文設(shè)計了一套飛輪儲能系統(tǒng),它包括飛輪儲能主體、控制系統(tǒng)和真空裝置。重點對其支承進(jìn)行了設(shè)計分析；給出了用于飛輪儲能系統(tǒng)的一種支承方案與支承軸承。本文設(shè)計的飛輪儲能系統(tǒng)采用一個徑向電磁軸承和一個軸向-徑向復(fù)合磁力軸承。重點介紹了軸向-徑向復(fù)合磁力軸承的結(jié)構(gòu)以及工作原理,采用等效磁路法對磁力軸承的磁路進(jìn)行了推算,建立了軸向和徑向懸浮力的計算公式以及其數(shù)學(xué)模型；給出了軸向-徑向復(fù)合磁力軸承的電磁以及永磁結(jié)構(gòu)參數(shù)的設(shè)計方法。 在確定了結(jié)構(gòu)參數(shù)的基礎(chǔ)上,對磁力軸承的特性進(jìn)行了分析,包括磁力軸承懸浮力的非線性分析,永磁體對磁力軸承的懸浮力的影響,軸向和徑向之間的耦合分析。 最后,以全電磁支承的飛輪轉(zhuǎn)子與采用軸向-徑向復(fù)合磁力軸承的飛輪轉(zhuǎn)子為對象,從質(zhì)量、儲能與轉(zhuǎn)子的動態(tài)特性等方面進(jìn)行了分析對比。
[Abstract]:Flywheel energy storage technology is a new type of energy storage technology.The flywheel energy storage system has the advantages of high specific energy, high specific power, small volume, fast charging, long life, no waste gas pollution and so on.Especially with the development of vacuum technology, composite material technology and magnetic levitation technology, the development and application of this new type of energy storage device is possible, which has a good development prospect.One of the key technologies of flywheel energy storage is its supporting technology. The supporting system of the flywheel should not only support the flywheel rotor and make it run reliably and stably, but also minimize the size of the whole flywheel rotor.Reduce energy loss due to support.In this paper, the bearing of flywheel rotor is studied.This paper introduces the basic principle and structure of flywheel energy storage system, summarizes the present research status of flywheel energy storage technology at home and abroad, and emphatically analyzes the research results and existing problems of flywheel energy storage support at home and abroad.In this paper, a flywheel energy storage system is designed, which includes the main body of flywheel energy storage, control system and vacuum device.The design and analysis of the bearing are emphasized, and a supporting scheme and bearing for the flywheel energy storage system are given.A radial magnetic bearing and an axial-radial composite magnetic bearing are used in the flywheel energy storage system designed in this paper.The structure and working principle of axial radial composite magnetic bearing are introduced emphatically. The magnetic circuit of magnetic bearing is calculated by using equivalent magnetic circuit method. The formula of axial and radial suspension force and its mathematical model are established.The design methods of electromagnetic and permanent magnetic structure parameters of axial-radial composite magnetic bearings are presented.On the basis of determining the structure parameters, the characteristics of magnetic bearing are analyzed, including the nonlinear analysis of the suspension force of magnetic bearing, the influence of permanent magnet on the suspension force of magnetic bearing, and the coupling analysis between axial and radial direction.Finally, taking the flywheel rotor with full electromagnetic support and the flywheel rotor with axial radial composite magnetic bearing as the object, the dynamic characteristics of mass, energy storage and rotor are analyzed and compared.
