【摘要】：电力行业是国民经济的支柱性行业,随着国民经济的高速发展,用电负荷的规模也在一步步的扩大。为了保障电能供应,电网公司需要不断加大电网建设。电网公司投资建设的项目在微观层面会对周边居民和企业的生产生活产生影响,在宏观层面则对整个地区的经济发展有着深远的影响。电网大规模建设在有效改善电网运行条件的同时,也因为建设融资来带的财务压力以及电网设备利用率低的原因导致的投资效益低等问题,给电网公司管理经营带来巨大压力。在新的环境下,需要进一步完善电网投资评价体系,对电网建设投资进行多角度评价,多方面衡量电网投资建设,从而为电网公司的投资管理工作提供更好的参考。基于此,本文在研究电网投资效益理论以及电网企业现行投资评价存在的问题的基础上,并结合前人的部分研究成果,首先提出了四层级较为全方位的的电网建设投资与评价标准体系。并引入灰色聚类三角函数进行电网建设综合评价,以更好的对处于不同发展阶段的各指标值进行归类与综合评分。首先,本文介绍了投资效益的内涵,并分析了电网企业投资评价及投资管理现状及其存在的问题。其次,从SMART原则出发,在综合考虑投资、收益、资产等三种因素的基础上,构建了包含主网投资评价、配网分公司投资评价、分专业投资评价和分电压等级投资评价等多级电网投资评价标准体系,共计56个关键指标。第三,采用相关性分析法对关键指标进行约简,再根据指标自身特性对其进行归一化处理。在综合考虑了不同类型的主客观赋权方法后,本文选取德尔菲法、变异系数法以及熵权法等三种方法进行线性组合赋权,以尽量保证评分的合理性。最后,本文选取某省级电网公司近两年的数据进行模型的实证分析,最终分别给出不同地市的主网架、配网、分专业电网及分电压等级电网投资评价综合评分。在此基础上,通过各地区分公司的实际情况验证模型的合理性,并针对最终评分给出具体的公司投资策略,以期为该公司的电网建设提供支持与借鉴。论文的研究成果省级电网公司的电网建设投资评价与投资管理提供较为全面的参考,有利于推动电网的快速、优质发展,有利于加快电网投资、提升资产质量,打破电网瓶颈对社会经济发展的阻碍,为社会经济发展提供坚实的电力保障。
[Abstract]:Power industry is the pillar industry of national economy. With the rapid development of national economy, the scale of power load is expanding step by step. In order to ensure the power supply, grid companies need to increase the power grid construction. The investment and construction projects of power grid companies will have an impact on the production and life of the surrounding residents and enterprises at the micro level, and on the macro level on the economic development of the whole region. The large-scale construction of power grid not only effectively improves the operating conditions of the power grid, but also brings great pressure to the management and management of the power grid company because of the financial pressure brought about by the construction financing and the low investment efficiency caused by the low utilization of the power network equipment. In the new environment, it is necessary to further improve the evaluation system of grid investment, to evaluate the investment in power grid construction from various angles, and to measure the investment and construction of power grid in many ways, thus providing a better reference for the investment management work of power grid companies. Based on this, this paper studies the theory of grid investment benefit and the problems existing in the current investment evaluation of power grid enterprises, combined with some previous research results. Firstly, a four-level and all-round investment and evaluation standard system for power grid construction is put forward. The grey clustering trigonometric function is introduced to the comprehensive evaluation of power network construction to better classify and evaluate the index values in different stages of development. Firstly, this paper introduces the connotation of investment benefit, and analyzes the present situation and existing problems of investment evaluation and investment management of power grid enterprises. Secondly, on the basis of smart principle and considering three factors: investment, income and assets, the paper constructs the investment evaluation of the main network and the investment evaluation of the branch company of distribution network. There are 56 key indexes in multi-level grid investment evaluation standard system, such as professional investment evaluation and sub-voltage grade investment evaluation. Thirdly, the key indexes are reduced by correlation analysis and normalized according to their own characteristics. After considering different types of subjective and objective weighting methods, this paper selects Delphi method, coefficient of variation method and entropy weight method to carry out linear combination weighting, in order to ensure the rationality of the score as much as possible. Finally, this paper selects the data of a provincial power grid company in the past two years for empirical analysis, and finally gives the comprehensive evaluation scores of the main grid, distribution network, specialized grid and voltage grade grid investment evaluation of different cities. On this basis, the rationality of the model is verified by the actual situation of each regional branch, and the specific investment strategy of the company is given according to the final score, in order to provide support and reference for the power grid construction of the company. The research results of this paper provide a more comprehensive reference for the investment evaluation and investment management of power grid construction in provincial power grid companies, which is conducive to promoting the rapid and high-quality development of the power grid, speeding up the investment in the power grid, and improving the quality of assets. Breaking the bottleneck of power grid hinders the development of social economy and provides a solid power guarantee for social and economic development.
