【摘要】：我国经济迅速发展大环境下,农村产业结构也经历着深刻的变革,农民生活质量显著提高,与经济发展相对应的实体加工企业和家用电器不断增加,农村用电量呈逐年上升的趋势。由于我国农村电网的建设时间较早,电压容量及线路的负荷承载已跟不上当下农村发展的需要,造成农村地区用电电力供需不匹配。目前,国家相关管理部门和电网公司相继出台各项政策来保证农村电网升级改造的顺利推进,提升农村电网在经济社会转型发展过程中能保驾护航能力。本文以廊坊大尚屯110kV变电站电网技改项目为研究背景,首先通过对国内外相关文献阅读并进行汇总分析,了解国内外电网技术改造项目评价的相关理论知识;接着阐述了电网升级改造项目及其评价的基础理论。其次通过对各种评价方法的简单介绍和对比选择分析出可以应用于电网升级改造项目评价的科学有效的评价方法;通过评价方法和评价思路的结合,为下文中进行具体的项目评价提供理论支持,从理论上指引廊坊大尚屯110kV变电站电网技改项目研究的整体实施过程。再从项目前期、项目准备、项目实施、项目验收、项目实现、项目运营、设备退出方案和其他方面影响等几个方面来对评价指标具体阐述分析,在此基础上,建立了廊坊大尚屯110kV变电站项目评价指标体系。并运用成功度评价法对廊坊大尚屯110kV变电站电网技改项目进行综合评价并计算出该项目的综合评价值;最后,对综合评价结果进行统计分析,找出该项目的成功之处,总结出项目实施后的一些结论。通过对廊坊大尚屯110kV变电站技改项目后评价结果的分析,结合项目实际情况总结了一些经验教训,以期能够对项目、项目执行机构和决策方面的一些建议;这些经验教训和相关建议都是项目完成后得到的宝贵财富,也必将对以后的类似项目实施提供重要的参考价值。对电网技术改造项目评价的研究可以为今后农网技术改造的投资决策提供科学依据,有利于提高电力企业的决策水平,进而促进电力企业经济、社会、环保等方面发展目标的实现。
[Abstract]:With the rapid economic development of our country, the rural industrial structure has also undergone profound changes, the quality of life of farmers has been improved significantly, and the number of physical processing enterprises and household appliances corresponding to the economic development has been increasing. Rural electricity consumption is increasing year by year. Because of the early construction time of rural power grid in our country, the voltage capacity and the load bearing of the line can no longer keep up with the needs of the current rural development, resulting in a mismatch between the supply and demand of electricity and power in rural areas. At present, the relevant national management departments and grid companies have issued various policies to ensure the smooth promotion of rural power grid upgrading and transformation, to enhance the rural power grid in the process of economic and social transformation and development can protect the ability. This paper takes Langfang Dashangtun 110kV substation power network technical reform project as the research background. Firstly, through reading and analyzing the relevant literature at home and abroad, we can understand the relevant theoretical knowledge of the domestic and foreign power grid technical transformation project evaluation. Then, the basic theory of power grid upgrade project and its evaluation is expounded. Secondly, through the simple introduction and comparative selection of various evaluation methods, the scientific and effective evaluation methods that can be applied to the evaluation of power grid upgrading and renovation projects are analyzed, and the combination of the evaluation methods and the evaluation ideas, It provides the theoretical support for the specific project evaluation below, and guides the whole implementation process of the research on the power grid technical reform project of Langfang Dashangtun 110kV substation theoretically. On the basis of the analysis of the evaluation index from several aspects, such as pre-project, project preparation, project implementation, project acceptance, project realization, project operation, equipment exit scheme and other aspects, etc. The evaluation index system of 110kV substation project in Langfang is established. The success degree evaluation method is used to evaluate the technical reform project of Langfang Dashangtun 110kV substation and the comprehensive evaluation value of the project is calculated. Finally, the results of the comprehensive evaluation are statistically analyzed to find out the success of the project. Some conclusions after the implementation of the project are summarized. Based on the analysis of the post-evaluation results of the technical transformation project of 110kV substation in Langfang, and combining with the actual situation of the project, this paper summarizes some experiences and lessons in order to make some suggestions on the project, the implementing organization of the project and the decision making. These lessons and relevant suggestions are valuable wealth after the completion of the project, and will certainly provide important reference value for the implementation of similar projects in the future. The research on the evaluation of the power grid technical transformation project can provide scientific basis for the investment decision of the technical transformation of the rural power network in the future, help to improve the decision-making level of the electric power enterprise, and then promote the economy and society of the electric power enterprise. The realization of environmental protection and other development goals.
