【摘要】：随着我国经济发展的不断提高,我国农村居民的生活水平和收入水平也快速的增长,而随之而来的对于农村供电在可靠性、稳定性以及安全性方面的要求也被提升到了一个新的高度,这种需求成为了摆在农村电网的规划方面的一个问题。我国农村建设的电网很多都是多年以前敷设的,而当时因为农村的用电情况非常少,但是如今我国经济发展的突飞猛击使得我国农村经济也水涨船高,农村用电量大增,如今为农村敷设的电网设备设施根本无法满足如今农村用电的需求,暴漏出来很多的问题,为了能够更好的研究农网改造项目工程,对农网改造方案的社会和经济影响进行全面的评价便显得尤为重要,既对工程中产生的影响进行了预测,也使农网改造项目具有相应的科学的决策依据。本文收集了大量关于农网改造的资料,首先介绍了电网预测及规划方法及项目评价的常用评价方法,并讲所介绍的预测方法应用到了威县农网的电荷预测中。其次,介绍了威县电网的基本情况,包括威县的县域情况、供电企业概况,从中对威县电网所存在的主要问题进行了分析。再次,从威县农网改造升级的目标、改造升级的主要任务等方面对威县农村电网的十三五规划方案进行了阐述。最后根据威县农村电网改造升级的主要任务,对威县农村电网改造升级的方案进行综合评价,在综合评价体系的构建、指标权重的赋值和模糊层次分析法等方面进行了相关的研究,设立了农村电网评价的四个一级指标安全性准则、电网核心性能准则、经济准则、社会及影响准则,采用了模糊层次分析法对威县农网改造方案进行了评价,得出方案可行的结论。并对威县农村提出了电网规划、安全用电等方面提出了建议,为威县农村电网的改造提供了经验。
[Abstract]:With the continuous improvement of China's economic development, the living standard and income level of rural residents in China have also increased rapidly, and the requirements for reliability, stability and safety of rural power supply have also been raised to a new height, which has become a problem in the planning of rural power grid. Many of the power grids built in rural areas of our country were laid many years ago, and at that time, because the electricity consumption in rural areas was very little, but now the rural economy of our country is also rising by leaps and bounds, and the electricity consumption in rural areas is also greatly increasing. Now, the power grid equipment and facilities laid for rural areas can not meet the needs of rural electricity consumption at all, and a lot of problems have been leaked out, in order to better study the rural network transformation project, It is particularly important to comprehensively evaluate the social and economic impact of the rural network transformation scheme. Not only the impact in the project is predicted, but also the rural network transformation project has the corresponding scientific decision-making basis. In this paper, a large number of data on the transformation of rural power network are collected. Firstly, the power grid prediction and planning methods and the common evaluation methods of project evaluation are introduced, and the prediction method is applied to the charge prediction of Weixian rural power network. Secondly, it introduces the basic situation of Weixian power grid, including the county situation of Weixian county, the general situation of power supply enterprises, and analyzes the main problems existing in Weixian power grid. Thirdly, the 13th five-year Plan of Weixian rural power grid is expounded from the aspects of the goal of transformation and upgrading of Weixian rural power network and the main tasks of transformation and upgrading. Finally, according to the main tasks of Weixian rural power grid transformation and upgrading, the scheme of Weixian rural power grid transformation and upgrading is comprehensively evaluated, and the related research is carried out in the aspects of the construction of comprehensive evaluation system, the assignment of index weight and fuzzy analytic hierarchy process (AHP). Four first-level index security criteria, power grid core performance criteria, economic criteria, social and impact criteria for rural power grid evaluation are established. The fuzzy analytic hierarchy process (AHP) is used to evaluate the transformation scheme of Weixian rural power network, and the conclusion is drawn that the scheme is feasible. Some suggestions on power grid planning and safe power consumption in Weixian rural areas are put forward, which provides experience for the transformation of Weixian rural power grid.
