【摘要】：隨著我國人民對(duì)生活環(huán)境要求的不斷提高，作為低碳清潔能源的天然氣近幾年在城市燃?xì)庵械膽?yīng)用也越來越普及，隨著國家輸氣主干網(wǎng)的建設(shè)其已成為我國城市燃?xì)獾闹饕獨(dú)庠�，隨之而來，天然氣的調(diào)峰問題變得十分突出，各地在用氣高峰頻繁出現(xiàn)氣源緊張的局面，昭示著我國各地天然氣調(diào)峰能力的欠缺。根據(jù)國外天然氣應(yīng)用較早的發(fā)達(dá)國家的經(jīng)驗(yàn)，天然氣的存儲(chǔ)能力是解決調(diào)峰的關(guān)鍵。因此有必要對(duì)天然氣儲(chǔ)氣調(diào)峰方式進(jìn)行詳細(xì)研究，，為區(qū)域燃?xì)庹{(diào)峰的優(yōu)化方式提供方向。 本文在分析了國內(nèi)外現(xiàn)有天然氣供應(yīng)調(diào)峰方式的基礎(chǔ)上，以北京市及深圳市為例進(jìn)行南北方地區(qū)天然氣的調(diào)峰方式進(jìn)行了分析，在對(duì)各種天然氣調(diào)峰方式分析比對(duì)的基礎(chǔ)上重點(diǎn)介紹了管道儲(chǔ)氣調(diào)峰能力計(jì)算及LNG接收站氣化調(diào)峰的主要工藝及設(shè)備，指出在南方地區(qū)發(fā)展以LNG接收站為主的氣化調(diào)峰設(shè)施更為有利；同時(shí)強(qiáng)調(diào)了對(duì)需求側(cè)的氣量管理，優(yōu)先發(fā)展可調(diào)峰用戶，可以減少對(duì)調(diào)峰設(shè)施的需求，從而降低長期合同的照付不議風(fēng)險(xiǎn)。珠三角區(qū)域是我國最主要的天然氣負(fù)荷需求中心，在該區(qū)域調(diào)峰市場(chǎng)形成后可利用現(xiàn)有調(diào)峰設(shè)施和資源取得較好的經(jīng)濟(jì)利益。 本文以深圳市為例，針對(duì)接收站的建設(shè)，從調(diào)峰需求入手，通過對(duì)負(fù)荷預(yù)測(cè)方法的研究，確定深圳市未來的天然氣需求量及調(diào)峰量，對(duì)各種可能的調(diào)峰方式進(jìn)行分析確定在充分利用已有高壓管道參與調(diào)峰的基礎(chǔ)上，深圳應(yīng)利用處于沿海的優(yōu)勢(shì)地理位置，建設(shè)自己的小型調(diào)峰接收站，并提出以接收站為依托的LNG氣化調(diào)峰功能輔以進(jìn)行LNG槽車貿(mào)易的工藝流程，并對(duì)主要設(shè)備進(jìn)行優(yōu)化比選，確定了主要的設(shè)備的選型，還對(duì)整個(gè)接收站的建設(shè)進(jìn)行了安全及社會(huì)影響進(jìn)行了說明，對(duì)整個(gè)系統(tǒng)運(yùn)行進(jìn)行經(jīng)濟(jì)性分析，指出項(xiàng)目實(shí)施具有良好的獨(dú)立生存能力。研究結(jié)果可為依托于城市燃?xì)獾男⌒徒邮照荆饣荆┑慕ㄔO(shè)和運(yùn)行提供了可借鑒的方法。
[Abstract]:With the continuous improvement of the living environment requirements of our people, the application of natural gas as low-carbon and clean energy in urban gas has become more and more popular in recent years. With the construction of the national gas transmission backbone network, it has become the main gas source of urban gas in our country, and the problem of peak shaving of natural gas has become very prominent, and the situation of gas source tension frequently appears in the peak of gas consumption everywhere. It shows the lack of natural gas peak-shaving capacity in various parts of our country. According to the experience of developed countries, the storage capacity of natural gas is the key to solve peak shaving. Therefore, it is necessary to study the peak shaving mode of natural gas storage in detail, so as to provide the direction for the optimization of regional gas peak shaving. On the basis of analyzing the existing modes of natural gas supply peak shaving at home and abroad, this paper takes Beijing and Shenzhen as an example to analyze the peak shaving mode of natural gas in the north and south of China. Based on the analysis and comparison of various natural gas peak shaving modes, the calculation of pipeline gas peak shaving capacity and the main process and equipment of gasification peak shaving at LNG receiving station are emphatically introduced. It is pointed out that it is more advantageous to develop gasification peak shaving facilities with LNG receiving stations as the main sites in southern China. At the same time, emphasis is placed on the demand-side gas management and the priority is given to the development of peak-adjustable users, which can reduce the demand for peak-shaving facilities and thus reduce the risk of long-term contract settlement. Pearl River Delta (PRD) region is the main demand center of natural gas load in China. After the formation of peak shaving market in this region, the existing peak shaving facilities and resources can be used to obtain better economic benefits. Taking Shenzhen as an example, aiming at the construction of receiving station, starting with the demand of peak shaving, through the study of load forecasting method, the future natural gas demand and peak shaving amount of Shenzhen are determined. On the basis of making full use of the existing high pressure pipelines to participate in peak shaving, Shenzhen should take advantage of the advantageous geographical position along the coast to build its own small peak shaving receiving station, according to the analysis of various possible peak shaving methods. At the same time, the LNG gasification peak shaving function based on the receiving station is put forward, and the trade process of the LNG tank truck is carried out. The main equipment is optimized and selected, and the selection of the main equipment is determined. The safety and social influence of the whole receiving station are also explained, the economic analysis of the whole system operation is carried out, and it is pointed out that the implementation of the project has a good independent survivability. The results can be used for reference for the construction and operation of a small receiving station (gasification station) based on urban gas.
