【摘要】：能源資源是人類社會生存和發(fā)展的重要物質(zhì)基礎(chǔ),也是我們?nèi)娼ㄔO(shè)小康社會、加快推進(jìn)社會主義現(xiàn)代化的重要物質(zhì)基礎(chǔ)。堅持節(jié)約資源的基本國策,加快建設(shè)資源節(jié)約型、環(huán)境友好型社會,促進(jìn)經(jīng)濟(jì)發(fā)展與人口、資源、環(huán)境相協(xié)調(diào),是貫徹落實(shí)科學(xué)發(fā)展觀、走新型工業(yè)化道路的必然要求�！皟尚鸵换焙汀皟尚腿隆笔菄W(wǎng)公司近幾年的工作路線,新的工作路線對變電站的改造提出了新的要求�！皟尚腿隆钡膬�(nèi)涵包括資源節(jié)約型、環(huán)境友好型、新技術(shù)、新材料、和新工藝�，F(xiàn)有變電站在電能運(yùn)輸過程中損耗較大,不利于節(jié)約資源。對變電站進(jìn)行改造,節(jié)約電能運(yùn)輸中的損耗成為電網(wǎng)建設(shè)項目的主要任務(wù)。隨著我國社會與經(jīng)濟(jì)的發(fā)展,現(xiàn)有變電站已經(jīng)無法滿足不斷增長的電力負(fù)荷要求。近幾年,高碑店的用電量和負(fù)荷保持了較快的增長速度,其中全社會用電量由2005年的4.7億千瓦時增長到2013年的12.94億千瓦時,年均增速為13.5%;全社會用電負(fù)荷由2005年的98.5MW增長至2013年的273MW,年均增速為13.6%。然而現(xiàn)有變電站供給的電力負(fù)荷無法滿足這一不斷增長的需求,變電站切改工程勢在必行。本文對高碑店220kV變電站配套切改項目進(jìn)行了設(shè)計,并在充分考慮了該項目特點(diǎn)的基礎(chǔ)上構(gòu)建了科學(xué)合理的評價指標(biāo)體系,運(yùn)用灰色層次分析法和成功度分析法分別對主觀評價指標(biāo)和客觀評價指標(biāo)進(jìn)行了分析與評價。論文主體主要分為四部分。首先,本文整理歸納了現(xiàn)有文獻(xiàn)研究的現(xiàn)狀與不足,闡述了切改工程實(shí)施與項目實(shí)施效果評價的相關(guān)理論,并通過分析多種方法的優(yōu)缺點(diǎn)選定了適用于本項目評價的方法——成功度評價法和灰色層次分析法相結(jié)合。其次,論文介紹了切改項目的方案設(shè)計及實(shí)施過程,為后續(xù)的實(shí)施效果評價奠定了基礎(chǔ)。再次,論文從項目管理過程、技術(shù)效果、財務(wù)效益和社會環(huán)境效益四個方面出發(fā),構(gòu)建了適用于該項目的評價指標(biāo)體系。結(jié)合該項目的實(shí)施情況,分別對項目的四項評價內(nèi)容進(jìn)行了分析與評價,并且運(yùn)用灰色評價分析法,對主觀性指標(biāo)進(jìn)行了評價,直接運(yùn)用成功度評價法對客觀性指標(biāo)進(jìn)行了評價,綜合評價結(jié)果為“良”。這一評價結(jié)果與項目的實(shí)際實(shí)施情況基本相符。最后,在評價過程中發(fā)現(xiàn)了可行性研究沒有得到足夠的重視,項目管理機(jī)制存在缺陷以及財務(wù)效益偏低的問題,針對評價過程中發(fā)現(xiàn)的問題,提出了提高可行性研究的充分性和嚴(yán)謹(jǐn)性,建立一套完善的項目管理機(jī)制以及控制項目投入成本,提高項目的財務(wù)效益的改進(jìn)意見。該研究成果對類似項目的設(shè)計與分析評價具有一定的參考和借鑒意義。
[Abstract]:Energy resources are not only the important material basis for the survival and development of human society, but also the important material basis for us to build a well-off society in an all-round way and speed up the socialist modernization. Persisting in the basic national policy of saving resources, speeding up the construction of resource-saving and environment-friendly society, and promoting the coordination of economic development with population, resources and environment are the inevitable requirements for carrying out the scientific concept of development and taking the road of new-type industrialization. "two types and one type" and "two types and three new" are the working routes of the company in recent years. The new working route puts forward new requirements for the transformation of substations. The connotation of "two types and three new" includes resource-saving, environment-friendly, new technology, new materials, and new technology. The current substation has a large loss in the process of electric energy transportation, which is not conducive to saving resources. The main task of the power grid construction project is to transform the substation and save the loss in the electric power transportation. With the development of our society and economy, the existing substation can not meet the increasing demand of power load. In recent years, Gaobeidian's electricity consumption and load have maintained a relatively rapid growth rate, with the total social electricity consumption increasing from 470 million kilowatt-hours in 2005 to 1.294 billion kilowatt-hours in 2013. The average annual growth rate is 13.5. The 98.5MW of the whole society grew from 273MWs in 2005 to 273MWs in 2013, with an average annual growth rate of 13.6m. However, the existing substation supply load can not meet this increasing demand. In this paper, the design of Gaobeidian 220kV Substation is designed, and a scientific and reasonable evaluation index system is constructed on the basis of fully considering the characteristics of the project. The subjective evaluation index and the objective evaluation index are analyzed and evaluated by using the grey analytic hierarchy process and the degree of success analysis. The main body of the thesis is divided into four parts. First of all, this paper summarizes the current situation and shortcomings of the existing literature research, and expounds the relevant theories of the implementation of the project and the evaluation of the effect of the implementation of the project. By analyzing the merits and demerits of many methods, this paper chooses the method of degree of success and grey analytic hierarchy process which is suitable for the evaluation of this project. Secondly, the paper introduces the project design and implementation process of the project, which lays a foundation for the evaluation of the implementation effect. Thirdly, from four aspects of project management process, technical effect, financial benefit and social environmental benefit, the paper constructs an evaluation index system suitable for the project. Combined with the implementation of the project, the four evaluation contents of the project are analyzed and evaluated, and the subjective indexes are evaluated by using the grey evaluation method. The objective index is evaluated directly by the method of degree of success, and the comprehensive evaluation result is "good". The evaluation results are basically consistent with the actual implementation of the project. Finally, in the process of evaluation, we found that the feasibility study has not been paid enough attention to, the project management mechanism is defective and the financial benefit is low, in view of the problems found in the evaluation process, The paper puts forward some suggestions to improve the adequacy and preciseness of the feasibility study, to establish a set of perfect project management mechanism, to control the project input cost, and to improve the financial benefit of the project. The research results have some reference significance for the design, analysis and evaluation of similar projects.
