摘要:能源、環(huán)境問題已經(jīng)成為制約我國經(jīng)濟可持續(xù)發(fā)展的一個重要瓶頸。調(diào)整能源結(jié)構(gòu)，提高能源利用率，節(jié)約能源，改善能源產(chǎn)業(yè)的安全性，解決環(huán)境污染問題已經(jīng)成為我國能源戰(zhàn)略的重點。而分布式能源系統(tǒng)正是集節(jié)能、經(jīng)濟、環(huán)保、供能可靠性于一身的新的能源供應方式，在我國有著廣泛的發(fā)展前景。 分布式能源系統(tǒng)是一種建立在能量梯級利用概念基礎上，分布安置在需求側(cè)的能源梯級利用，以及資源綜合利用和可再生能源設施。通過在需求現(xiàn)場根據(jù)用戶對能源的不同需求，實現(xiàn)溫度對口供應能源，將輸送環(huán)節(jié)的損耗降至最低，從而實現(xiàn)能源利用效能的最大化。 本文在對分布式能源系統(tǒng)的概念、組成、基本原理進行介紹的基礎上，分析比較了以發(fā)電設備為核心的不同的分布式能源系統(tǒng)方案，闡明了其各自的工作原理，應用特點，通過分析計算，研究了分布式能源系統(tǒng)的節(jié)能條件，并在不同參數(shù)變化下，對供熱期、制冷期的節(jié)能率進行了分析，同時進行了聯(lián)產(chǎn)與分產(chǎn)系統(tǒng)的火用分析比較，說明了分布式能源系統(tǒng)的節(jié)能性。 文章對各種分布式能源配置原則進行了闡述，選擇了不同的經(jīng)濟性分析指標，以華北地區(qū)的某辦公大樓為研究對象，分別采取以熱定電和以電定熱的原則，并在不同原則下，選擇不同的系統(tǒng)配置方案。通過優(yōu)化，確定了不同燃機臺數(shù)配置下的最佳容量，電網(wǎng)的購電量，冷熱補燃量等參數(shù)組合。并將優(yōu)化的方案與以經(jīng)驗確定負荷的方案進行了對比，從中可以看出燃氣內(nèi)燃機方案作為辦公樓分布式能源系統(tǒng)的優(yōu)越性。 關(guān)鍵詞： 分布式能源系統(tǒng) 節(jié)能 經(jīng)濟性 優(yōu)化
Abstract:Nowadays，energy and environment problems have become the boRleneck that limits the sustainable development of the economy of OUr country．Regulating the energy construction，raising the energy utilizing efficiency,save energy,improving the security of energy industry and solving the environment pollution have become the emphases of the energy stratagem of our country．Distributed energy system is just about a new energy supply mode which integrates energy saving，economy,environment protceting，reliable energy supply,and shows broad future in our country． Distributed energy system is the establishment of energy step utilization， resource integrated using and renewable energy,which is set up based on energy step utilization conception，and allocated separately at the demand side．According to the different demands of the customers，the energy supply is carried out with the match of temperature and the energy loss during the transportation is reduced to the lowest． Thereby the efficiency of the energy using becomes the highest． In the thesis，based on the introduction to the conception，composing，and the basic principles of the distributed energy system，different distributed energy system projects which take the electricity generation device as the kernel part are analyzed and compared．And these projects’working principle and application features are clarified respectively． And also analyzes and compares the exergy of cogeneration system and separate production system，which Can explain the distributed energy system’S energy saving characteristic． In the thesis，various collocation principle of distributed energy system is illuminated．Different economy analysis indicators is chosen，and as a research object of certain office block in north China．Through optimization，the best capability of gas—burned machine，purchasing electricity from net，cooling and heating complemented by gas burned is confirmed for various quantity collocation．Meanwhile，comparison between optimized scheme and the scheme which is confirmed by experience is carried through,among this，it can be seen that gas engine scheme has advantage for office block distributed energy system． Key words：Distributed Energy System, Energy conservation, Eenomy, Optimization |
