【摘要】：壓縮空氣儲(chǔ)能系統(tǒng)是一種日趨成熟的儲(chǔ)能方式,其以環(huán)境友好、使用壽命長(zhǎng)、投資成本低等優(yōu)勢(shì),開(kāi)始得到人們的普遍關(guān)注。目前,國(guó)外已有數(shù)座壓縮空氣儲(chǔ)能電站建立,均為大容量?jī)?chǔ)能。然而,大容量?jī)?chǔ)能系統(tǒng)受到地理?xiàng)l件的影響,極大的限制了其發(fā)展。小型甚至微小型壓縮空氣儲(chǔ)能系統(tǒng)的研發(fā)大多處于理論層面,還未投入商業(yè)運(yùn)行。微小型壓縮空氣儲(chǔ)能系統(tǒng)與傳統(tǒng)壓縮空氣儲(chǔ)能電站相比,無(wú)需燃燒化石燃料,真正實(shí)現(xiàn)零排放,且改用儲(chǔ)氣裝置來(lái)存儲(chǔ)壓縮氣體,對(duì)地理?xiàng)l件沒(méi)有要求,使用靈活方便,因而可用作備用電源、微型智能電網(wǎng)和獨(dú)立偏遠(yuǎn)供電網(wǎng)等�？梢�(jiàn),研究微小型壓縮空氣儲(chǔ)能系統(tǒng)具有重要的現(xiàn)實(shí)意義。 本文主要研究一種新型壓縮空氣儲(chǔ)能方式——微小型全橋式液氣循環(huán)壓縮空氣儲(chǔ)能,該技術(shù)壓縮效率高,響應(yīng)迅速。關(guān)鍵技術(shù)是液泵、液力馬達(dá)的控制,對(duì)液泵、液力馬達(dá)的控制策略將極大的影響系統(tǒng)的壓縮過(guò)程,系統(tǒng)的整體效率等。因此本文在對(duì)儲(chǔ)能系統(tǒng)工作特性進(jìn)行詳細(xì)分析的基礎(chǔ)上,重點(diǎn)研究了儲(chǔ)能系統(tǒng)的控制策略。首先,對(duì)國(guó)內(nèi)外的儲(chǔ)能技術(shù)及其控制算法做了簡(jiǎn)單的介紹。其次,研究了微小容量壓縮空氣儲(chǔ)能系統(tǒng)的工作特性。對(duì)于本課題中研究的微小容量全橋式壓縮空氣儲(chǔ)能系統(tǒng)進(jìn)行了詳細(xì)介紹,并對(duì)系統(tǒng)中機(jī)電轉(zhuǎn)換環(huán)節(jié)即液泵和電機(jī)的特性進(jìn)行了研究。再次,對(duì)儲(chǔ)能系統(tǒng)的控制策略進(jìn)行研究。重點(diǎn)研究了最大效率點(diǎn)跟蹤控制、最大功率點(diǎn)跟蹤控制和結(jié)合最大功率點(diǎn)和最大效率點(diǎn)跟蹤控制的優(yōu)化的最大效率點(diǎn)跟蹤控制算法,即混合控制算法。對(duì)比不同控制算法對(duì)系統(tǒng)工作特性的影響,主要對(duì)功率和效率參數(shù)進(jìn)行了分析。最后,基于Matlab/Simulink利用宏觀能流表示法搭建液氣循環(huán)壓縮空氣儲(chǔ)能系統(tǒng)模型,對(duì)系統(tǒng)分別在上述三種控制策略下的工作狀態(tài)進(jìn)行了仿真,驗(yàn)證了理論分析的正確性。并在實(shí)驗(yàn)室條件下設(shè)計(jì)搭建了實(shí)驗(yàn)平臺(tái)進(jìn)行實(shí)驗(yàn)驗(yàn)證。
[Abstract]:Compressed air energy storage system is a more and more mature energy storage method. It has been paid more and more attention due to its advantages of friendly environment, long service life and low investment cost.At present, a number of compressed air energy storage power stations have been established abroad, all of which are large capacity energy storage.However, the development of large capacity energy storage system is greatly restricted by geographical conditions.The R & D of small and even micro compressed air energy storage system is mostly in the theoretical level and has not yet been put into commercial operation.Compared with traditional compressed air energy storage power station, micro compressed air energy storage system can realize zero emission without burning fossil fuel, and use gas storage device to store compressed gas, which has no requirement for geographical conditions and is flexible and convenient to use.Therefore, it can be used as backup power source, micro smart grid and independent remote power supply network.Therefore, it is of great practical significance to study the micro compressed air energy storage system.In this paper, a new type of compressed air energy storage method, micro-bridge type liquid-gas circulating compressed air energy storage, is studied. The technology has high compression efficiency and rapid response.The key technology is the control of hydraulic pump and hydraulic motor. The control strategy of hydraulic pump and hydraulic motor will greatly affect the compression process of the system and the overall efficiency of the system.Therefore, based on the detailed analysis of the working characteristics of the energy storage system, the control strategy of the energy storage system is studied in this paper.Firstly, the energy storage technology and its control algorithm at home and abroad are briefly introduced.Secondly, the working characteristics of the micro-capacity compressed air energy storage system are studied.The micro-capacity full-bridge compressed air energy storage system studied in this paper is introduced in detail, and the characteristics of the electromechanical conversion link, that is, hydraulic pump and motor, are also studied.Thirdly, the control strategy of energy storage system is studied.The maximum efficiency point tracking control, the maximum power point tracking control and the optimal maximum efficiency point tracking control algorithm combining the maximum power point tracking control with the maximum efficiency point tracking control, that is, the hybrid control algorithm, are studied in this paper.The power and efficiency parameters are analyzed by comparing the effects of different control algorithms on the operating characteristics of the system.Finally, based on Matlab/Simulink, the model of liquid-gas circulating compressed air energy storage system is built by using macroscopic energy flow representation, and the simulation of the system working state under the three control strategies is carried out, which verifies the correctness of the theoretical analysis.The experimental platform is designed and built under the laboratory conditions for experimental verification.
