文档介绍：摘 要
城市电网是电力系统主要负荷中心,作为城市的重要基础设施之一,与城市的社会经济发展密切相关。城市电网规划是城市总体规划的重要组成部分,应与城市的各项发展规划相互配合、同步实施,其目标就是使电网的发展能适应、满足并适度超前于供电区域内的经济发展需求,有效地增强城市电网网架结构,保障城市电网(包括其二次系统)与市政建设改造协调发展,做到与城市规划相协调。城网规划的目标是通过科学的规划,建设网络坚强、结构合理、安全可靠、运行灵活、节能环保、经济高效的城市电网,不断提高城网供电能力和电能质量, 以满足城市经济增长和社会发展的需要。
本文按照内蒙古电力公司“十二五”期间电网建设的总体要求,依据包头地区城市总体规划及电网基本现状,总结近年来地区负荷发展情况,结合包头市“十二五”经济社会发展规划,利用总量预测方法,通过趋势外推法建立多种预测模型对近期城区负荷进行预测,对远期负荷利用负荷密度法进行预测,并提出具体的包头城市配电网规划方案,通过实施以达到改善与优化包头市城市电网结构, 有效提高供电可靠性和电能质量、有效降低损耗的目的,切实提高电网、设备的整体技术水平和智能化水平,确保电网安全经济运行,为包头市社会经济的快速健康发展提供坚实的基础和强有力的保障。
通过分析当前城市中心区现状及近年来包头城市发展的历程,总结了近年来包头市城市配电网建设取得的成就及当前配电网存在的不足之处,为“十二五”期间城市配电网建设发展指明方向。根据包头市城市建设规划和经济发展展望, 结合“十二五”期间和远期的电力需求预测,同时根据上级电网规划的结果,紧密结合包头城市配电网实际情况,制定符合包头城市经济发展实际的技术原则, 对“十二五”期间包头市配电网的网架结构和网络规模进行分层分区规划并编制出分年度投资计划。

Abstract
Urban grid is the main load center of power system. As one of the city's critical infrastructure, it is closely related the city's social and economic development. Urban distribution system planning is an important part of the overall plan of the city. It should patible with the development of the city with the purpose of moderating and ahead of the power supply to meet the region's economic development needs. The purpose of urban distribution system planning is construct a system which has work, reasonable architecture, and is reliable, flexible, energy saving and economical through scientific planning. It should enhance power supply capability and reliability continuously and satisfies the social development need.
In accordance with the Inner Mongolia Electric pany "12th fives" during the general requirements of power grid construction, and based on the overall urban planning and Baotou basic status work, this paper have made the load forecasting, and proposed work planning project. The purpose such as Improving and optimizing the grid structure of Baotou, ensuring the safe and economic operation power was achieved. The planning project provided a solid foundation and strong protect
