【摘要】：价值工程(VE)是从技术和经济相结合的角度,对所研究对象的功能与费用进行系统分析,不断创新,旨在提高所研究对象价值的一种思想方法和管理技术。 “十一五”时期,我国风力发电大规模发展,但是我国的大部分风电项目并没有因为快速增长而实现应有的效益,究其原因是多方面因素造成的,如初始一次性投资大而项目回收期长,而且受运营期上网电量和风电电价的限制,项目盈利能力有限,甚至有些项目自投产之日就逐步呈现出亏损状态。针对风电项目此类问题,本文基于价值工程理论,从功能与成本两个角度出发,分析了影响风电项目价值的关键因素,通过分析,本文选择风电场宏观选址、风力发电机组选型以及风电项目施工建设进度作为价值提升改进的研究对象。在风电场宏观选址方面,鉴于风电场宏观选址是一个涉及风能资源、地形地质、电网条件等众多因素的综合评价决策过程,本文在总结我国风电场宏观选址的现状与发展趋势后,详细探讨分析了影响宏观选址的主要影响因素以及风电场选址价值评价特点,在此基础上,提出基于发电量与成本估算的宏观选址价值评价的思路与方法。在风力发电机组选型方面,特定的风能资源条件下,机组选型不仅关系到风电项目的年发电量,而且是决定建设成本的关键因素。本文从发电量与成本两个方面出发,提出以特定建设成本和特定度电建设成本概念为基础的风力发电机组优化选型方法。在风电项目施工建设进度方面,基于风电项目建设内容及施工特点,探讨风电项目的快速建设方法,提出设计-施工并行与并行流水施工作业的快速开发建设方法,在不增加成本的同时,可以大大缩短建设期,实现项目提前投产发电的目标。本文通过理论和实践的结合,取得了一些研究成果,为以后的风电项目建设与相关研究提供一定的借鉴作用。
[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.
