【摘要】：电网规划对电力企业的长远发展的起重要作用,是国民经济和社会发展的重要组成部分,对整个国家的发展起基础支撑作用。电网规划的作用是使电网的未来的发展建设适应、满足并适度超前于规划地区内的经济发展需求,并能发挥其对于电网建设、运行和供电保障的先导和决定作用,同时合理制定投资计划,提高投资效益。按照省公司“十三五”期间对电网建设的总体要求,根据电网基本现状同时满足A县总体规划,对A县“十三五”期间电网建设进行规划以求达到改善与优化A县电网结构、保障电网与城乡建设改造协调发展、降低网络损耗、提高供电可靠性和电能质量、实现电网智能化,建设满足负荷增长需要、结构清晰、布局合理的坚强电网,以满足A县国民经济和社会发展对电力的需求。本文首先介绍了论文研究背景意义;再介绍分析A县电源现状与电网现状及存在的问题,根据实际数据描述年负荷特性与日负荷特性曲线,并对影响因素进行了分析;接着介绍了电力负荷预测的整体思路与方法,重点介绍了本文的使用的综合用电水平法、电力弹性系数法、多元线性回归法、重点用户法等并对2015-2020年间的电力负荷进行预测,按用电性质与地理位置,进行分区电力电量平衡计算;按电力电量平衡的计算结果对220KV、110KV变电容进行平衡计算,给出两套建设方案并推荐一个方案,按照变电站布点技术要求进行了布点规划;由变电站的布点位置,进行主网架规划,保证潮流的合理性满足经济发展的需求,并给出了分年电网建设投资总额;最后结合国家对智能电网的大力建设,对A县的电网智能化建设提出了三个专项规划,分别是配电自动化规划、电动汽车充电桩专项规划、智能用电小区规划。
[Abstract]:Power grid planning plays an important role in the long-term development of power enterprises, is an important part of the national economy and social development, and plays a basic supporting role in the development of the whole country. The function of power network planning is to adapt the future development and construction of the power network, to meet and moderately advance the economic development demand in the planned area, and to play its leading and decisive role in power grid construction, operation and power supply guarantee. At the same time, rational formulation of investment plans to improve investment efficiency. According to the overall requirements of the provincial company for power grid construction during the 13th Five-Year Plan period, according to the basic current situation of the power grid and satisfying the overall plan of County A, the construction of the power network in County A during the 13th Five-Year Plan period is planned in order to improve and optimize the power network structure of County A. To ensure the coordinated development of the power network and the urban and rural construction, reduce network losses, improve the reliability and quality of power supply, realize the intellectualization of the power network, and build a strong grid that meets the needs of load growth, has a clear structure, and has a reasonable layout. In order to meet the needs of the national economy and social development of A County for electricity. This paper first introduces the background significance of the paper, then introduces and analyzes the current situation of power supply and power network in A County and the existing problems, describes the annual load characteristic and daily load characteristic curve according to the actual data, and analyzes the influencing factors. Then it introduces the whole idea and method of power load forecasting, especially introduces the comprehensive power level method, power elasticity coefficient method, multivariate linear regression method, key user method and so on, and forecasts the electric power load in 2015-2020. According to the electric properties and geographical location, the district electric power balance is calculated, and the 220kV / 110KV variable capacitance is balanced according to the result of the calculation, and two sets of construction schemes are given and one scheme is recommended. The layout planning is carried out according to the technical requirements of substation layout, the main grid planning is carried out by the location of substation layout, the rationality of power flow is ensured to meet the needs of economic development, and the total investment amount of power grid construction is given. Finally, combined with the national construction of smart grid, three special plans are put forward for the intelligent construction of power grid in A county, namely, distribution automation planning, electric vehicle charging pile special planning, intelligent power use district planning.
