【摘要】：價(jià)值工程(VE)是從技術(shù)和經(jīng)濟(jì)相結(jié)合的角度,對所研究對象的功能與費(fèi)用進(jìn)行系統(tǒng)分析,不斷創(chuàng)新,旨在提高所研究對象價(jià)值的一種思想方法和管理技術(shù)。 “十一五”時(shí)期,我國風(fēng)力發(fā)電大規(guī)模發(fā)展,但是我國的大部分風(fēng)電項(xiàng)目并沒有因?yàn)榭焖僭鲩L而實(shí)現(xiàn)應(yīng)有的效益,究其原因是多方面因素造成的,如初始一次性投資大而項(xiàng)目回收期長,而且受運(yùn)營期上網(wǎng)電量和風(fēng)電電價(jià)的限制,項(xiàng)目盈利能力有限,甚至有些項(xiàng)目自投產(chǎn)之日就逐步呈現(xiàn)出虧損狀態(tài)。針對風(fēng)電項(xiàng)目此類問題,本文基于價(jià)值工程理論,從功能與成本兩個角度出發(fā),分析了影響風(fēng)電項(xiàng)目價(jià)值的關(guān)鍵因素,通過分析,本文選擇風(fēng)電場宏觀選址、風(fēng)力發(fā)電機(jī)組選型以及風(fēng)電項(xiàng)目施工建設(shè)進(jìn)度作為價(jià)值提升改進(jìn)的研究對象。 在風(fēng)電場宏觀選址方面,鑒于風(fēng)電場宏觀選址是一個涉及風(fēng)能資源、地形地質(zhì)、電網(wǎng)條件等眾多因素的綜合評價(jià)決策過程,本文在總結(jié)我國風(fēng)電場宏觀選址的現(xiàn)狀與發(fā)展趨勢后,詳細(xì)探討分析了影響宏觀選址的主要影響因素以及風(fēng)電場選址價(jià)值評價(jià)特點(diǎn),在此基礎(chǔ)上,提出基于發(fā)電量與成本估算的宏觀選址價(jià)值評價(jià)的思路與方法。 在風(fēng)力發(fā)電機(jī)組選型方面,特定的風(fēng)能資源條件下,機(jī)組選型不僅關(guān)系到風(fēng)電項(xiàng)目的年發(fā)電量,而且是決定建設(shè)成本的關(guān)鍵因素。本文從發(fā)電量與成本兩個方面出發(fā),提出以特定建設(shè)成本和特定度電建設(shè)成本概念為基礎(chǔ)的風(fēng)力發(fā)電機(jī)組優(yōu)化選型方法。 在風(fēng)電項(xiàng)目施工建設(shè)進(jìn)度方面,基于風(fēng)電項(xiàng)目建設(shè)內(nèi)容及施工特點(diǎn),探討風(fēng)電項(xiàng)目的快速建設(shè)方法,提出設(shè)計(jì)-施工并行與并行流水施工作業(yè)的快速開發(fā)建設(shè)方法,在不增加成本的同時(shí),可以大大縮短建設(shè)期,實(shí)現(xiàn)項(xiàng)目提前投產(chǎn)發(fā)電的目標(biāo)。 本文通過理論和實(shí)踐的結(jié)合,取得了一些研究成果,為以后的風(fēng)電項(xiàng)目建設(shè)與相關(guān)研究提供一定的借鑒作用。
[Abstract]:Value engineering (VE) is a kind of thought method and management technology which systematically analyzes and innovates the function and cost of the studied object from the point of view of the combination of technology and economy, aiming at improving the value of the studied object. During the Eleventh five-year Plan period, China's wind power generation developed on a large scale, but most of the wind power projects in China did not achieve their due benefits because of rapid growth, which was caused by many factors. For example, the initial one-off investment is large and the project payback period is long, and limited by the operation period of online electricity and wind power price, the profitability of the project is limited, and even some projects gradually show a state of loss since the date of commissioning. Aiming at this kind of problem of wind power project, based on the theory of value engineering, this paper analyzes the key factors that affect the value of wind power project from the point of view of function and cost. Through the analysis, this paper selects the macro location of wind farm. The selection of wind turbine and the construction progress of wind power project are the research objects of value enhancement and improvement. In the aspect of macro location of wind farm, in view of the fact that macro location of wind farm is a comprehensive evaluation and decision-making process involving many factors, such as wind energy resources, topographic geology, power grid conditions and so on, After summing up the present situation and development trend of macro location of wind farm in China, this paper discusses and analyzes in detail the main influencing factors of macro location and the evaluation characteristics of location value of wind farm. The idea and method of macro location value evaluation based on power generation and cost estimation are put forward. In the aspect of wind turbine selection, under the specific wind energy resources, unit selection is not only related to the annual power generation of wind power project, but also the key factor to determine the construction cost. From two aspects of power generation and cost, this paper puts forward an optimal selection method of wind turbine based on the concepts of specific construction cost and specific power construction cost. In the aspect of construction progress of wind power project, based on the construction content and construction characteristics of wind power project, the rapid construction method of wind power project is discussed, and the rapid development and construction method of design-construction parallel and parallel pipeline construction operation is put forward. Without increasing the cost, the construction period can be greatly shortened and the project can be put into production ahead of time. In this paper, through the combination of theory and practice, some research results have been obtained, which can be used as a reference for the future wind power project construction and related research.
