【摘要】：电力行业是影响我国经济发展的基础行业。电力行业平稳而迅速地发展对我国经济发展起到至关重要的作用。进入21世纪以来,电力需求呈现日益增长的态势,传统的电力发展已经不能满足我国的经济发展和社会生产力的需求,因此智能电网应运而生。在智能电网大力发展的背景下,配电自动化被广泛应用,建设配电自动化主站项目也就成为当下的重中之重。但是在我国此类项目建设周期较长,投入资金数额较大,耗费资源较多,考虑因素广泛,结构功能复杂多变,所以在配电自动化项目投资和实施前进行科学的项目前评估尤为重要,不仅可以确保工程项目建成过程的安全可靠,还可以获得项目投产后的预期的收益。因此,客观地采用项目前评估方法分析电力行业项目的可行性十分重要。本文采用熵权模糊综合评价的方法对内蒙古通辽配电自动化主站项目进行前评估,最终目的是分析该项目的可行性,是否可以满足投资方预期收益的要求。在具体内容上,首先概述了配电自动化主站项目前评估的研究背景与意义、国内外前评估的发展情况、本文的研究内容与研究方法;阐述了配电自动化项目前评估的基本理论,包括项目前评估的基本原则与一般程序、项目前评估的主要内容以及项目前评估的基本方法;其次结合配电自动化主站项目的基本特点和相关政策、文件要求,从技术层面、经济层面和社会效益层面构建配电自动化主站项目的前评估指标体系,然后采用客观性较强的熵权法确定该项目的体系指标权重,同时计算隶属度,接下来建立配电自动化主站项目的多层级模糊综合评价模型,包括模糊综合评价的基本内容和一般步骤;最后以通辽配电自动化主站项目为实际的案例进行前评估研究。结果表明,通辽配电自动化主站项目满足投资方的要求,并证明了运用熵权模糊综合评价方法无论从理论上还是实践上都是可行的,能够对配电自动化主站项目进行有效评价,为投资方进行借投资决策提供参考价值。
[Abstract]:The electric power industry is the basic industry which affects the economic development of our country. The smooth and rapid development of the power industry plays a vital role in the economic development of our country. Since twenty-first Century, the demand for electricity has been increasing, and the traditional power development has not met the needs of the economic development and the social productivity of our country, so it is wise. Power grid emerges as the times require. In the context of the vigorous development of smart grid, distribution automation is widely used, and the construction of the main station project of distribution automation has become the top priority. However, in our country, the construction cycle of this kind of project is long, the amount of investment is large, the cost of resources is large, the factors are widely considered, and the structure function is complex and changeable. It is particularly important to make a scientific pre project evaluation before investment and implementation of the distribution automation project, not only to ensure the safety and reliability of the construction process, but also to obtain the expected returns after the project is put into production. Therefore, it is very important to analyze the feasibility of the electric power industry project by using the pre project evaluation method objectively. The method of entropy weight fuzzy comprehensive evaluation is used to evaluate the main station project of Tongliao distribution automation in Inner Mongolia. The final purpose is to analyze the feasibility of the project and whether it can meet the expected returns of the investor. In the specific content, the research background and significance of the pre evaluation of the main station project in distribution automation are summarized, and the pre assessment at home and abroad is given. The basic theory of the pre project evaluation of distribution automation, including the basic principles and general procedures of pre project evaluation, the main contents of pre project evaluation and the basic method of pre project evaluation, and the basic characteristics of the main station project of distribution automation and the related policies, are discussed. The document requires that the pre evaluation index system of the main station project of distribution automation is constructed from the technical level, the economic level and the social benefit level. Then the system index weight of the project is determined by the objective entropy weight method, and the degree of membership is calculated. Then the multi-layer fuzzy comprehensive evaluation model of the main station project of distribution automation is established. It includes the basic content and general steps of fuzzy comprehensive evaluation. Finally, it takes the Tongliao distribution automation main station project as the actual case to carry out the pre evaluation study. The result shows that the main station project of Tongliao distribution automation station meets the requirements of the investor, and proves that the fuzzy comprehensive evaluation method using entropy weight is both theoretically and practically. It can effectively evaluate the main station project of distribution automation and provide reference value for investors to make investment decisions.
