【摘要】：能源危機(jī)和環(huán)境保護(hù)已經(jīng)成為世界各國研究的重要課題。為實現(xiàn)國家可持續(xù)發(fā)展,世界各工業(yè)國家都積極研究開發(fā)新能源和環(huán)保節(jié)能產(chǎn)品。在此背景下,港口起重機(jī)械作為耗能大戶,提出了高效化,綠色化的發(fā)展方向。鑒于混合動力技術(shù)在汽車上的成功應(yīng)用,混合動力系統(tǒng)在起重機(jī)械上的研究應(yīng)用也越來越廣泛。本文以武漢理工大學(xué)研發(fā)的基于超級電容的直流90KW混合動力輪胎式起重機(jī)為研究對象,在分析系統(tǒng)總體構(gòu)成和各模塊工作原理的基礎(chǔ)上,建立各模塊的數(shù)學(xué)模型,并利用SABER仿真軟件構(gòu)建各模塊的仿真模型,對系統(tǒng)的典型工況進(jìn)行模擬,在分析過程中,不斷優(yōu)化系統(tǒng)的控制策略,以實現(xiàn)更大的節(jié)能效果。 論文首先分析了能源危機(jī),可持續(xù)發(fā)展的相關(guān)背景,介紹了混合動力系統(tǒng)的典型結(jié)構(gòu)及各結(jié)構(gòu)對應(yīng)的控制策略,分析了混合動力技術(shù)在汽車行業(yè)和起重機(jī)行業(yè)的發(fā)展概況,并對仿真技術(shù)的發(fā)展作了簡要介紹。 其次,對基于超級電容的直流90KW混合動力輪胎式起重機(jī)的組成結(jié)構(gòu)和控制系統(tǒng)構(gòu)成作了簡要介紹,分析了系統(tǒng)主要動力部件的技術(shù)參數(shù),包括超級電容、發(fā)動機(jī)和各機(jī)構(gòu)工作電機(jī)的技術(shù)參數(shù)；并簡要介紹系統(tǒng)的控制策略,包括系統(tǒng)總體控制策略,超級電容控制策略以及發(fā)動機(jī)的控制策略。 然后從仿真的角度,在分析系統(tǒng)各模塊特性及工作原理的基礎(chǔ)上,對各個模塊進(jìn)行合理簡化,建立各模塊的數(shù)學(xué)模型,并在SABER軟件中,采用MAST語言描述構(gòu)建了個模塊的仿真模型,包括柴油發(fā)動機(jī)模型、超級電容模型、雙向DC/DC變換器模型、H橋斬波器模型、他勵直流電機(jī)模型等。 最后,整合集成系統(tǒng)各模塊,構(gòu)建起重機(jī)混合動力系統(tǒng)仿真模型,完成對典型工況的模擬分析,通過對比仿真實驗,分析系統(tǒng)的節(jié)油效率,提出控制策略的優(yōu)化方案。
[Abstract]:Energy crisis and environmental protection have become an important research topic in the world. In order to realize the national sustainable development, the industrial countries all over the world are actively researching and developing new energy sources and environmental protection and energy saving products. As a large energy user, port hoisting machinery has put forward the development direction of high efficiency and green. In view of the successful application of hybrid power technology in automobile, The research and application of hybrid power system in lifting machinery is more and more extensive. In this paper, the DC 90KW hybrid electric tire crane based on super capacitor developed by Wuhan University of Technology is taken as the research object. On the basis of analyzing the overall structure of the system and the working principle of each module, the mathematical model of each module is established, and the simulation model of each module is constructed by using SABER software, and the typical operating conditions of the system are simulated. Continuously optimize the control strategy of the system to achieve greater energy-saving effect. Firstly, the paper analyzes the related background of energy crisis and sustainable development, introduces the typical structure of hybrid power system and the corresponding control strategy of each structure, and analyzes the development of hybrid power technology in automobile industry and crane industry. The development of simulation technology is briefly introduced. Secondly, the composition and control system of 90KW DC hybrid tire crane based on super capacitor are introduced briefly, and the technical parameters of main power components of the system, including super capacitor, are analyzed.
