【摘要】：我国各地经济社会发展和电网特点差异明显,若按统一的标准建设配电网,会造成设备资产利用率不高甚至严重浪费的情况,在技术、经济上不合理,因此,迫切需要对配电网供电区域进行划分。通过分析影响配电网供电区域划分的主要因素,从政治、经济、负荷3个方面建立了配电网供电区域划分的指标体系,提出了配电网供电区域划分方法与流程;应用聚类分析法对我国342个地市样本数据进行聚类分析,得出了实用的供电区域划分标准;并将该标准和综合评价法应用于北京实际案例,得出了较为一致的结论,验证了2种方法的有效性,克服了现有方法只靠专家经验定性分类的缺点,可适用于不同类型、不同大小供电区域的划分,能够为差异化的配电网规划设计技术导则及相关技术标准的制定奠定基础。
[Abstract]:There are obvious differences in economic and social development and power network characteristics in various parts of our country. If the distribution network is built according to the unified standards, it will result in low utilization of equipment assets and even serious waste, which is not reasonable in technology and economy, therefore, There is an urgent need to divide the power supply area of the distribution network. Based on the analysis of the main factors affecting the division of distribution network power supply area, the index system of distribution network power supply area division is established from three aspects of politics, economy and load, and the method and flow of distribution network power supply area division are put forward. Based on the cluster analysis of 342 sample data of cities and cities in China, the practical power supply area classification standard is obtained, and the standard and the comprehensive evaluation method are applied to the actual cases in Beijing, and a more consistent conclusion is drawn. The validity of the two methods is verified, and the shortcomings of the existing methods are overcome, which can be applied to the division of power supply areas of different types and sizes. It can lay a foundation for the establishment of differential distribution network planning and design technical guidelines and related technical standards.
