【摘要】 城市电网规划是一个具有多目标性、不确定性、非线性和多阶段性等特点的复杂系统优化问题,是电力工程前期工作的重要部分。在智能电网背景下,采用先进理论和技术进行电网规划,对提高县域电网的运行水平和经济社会效益具有重要的意义。本文对城市电网规划的理论和实用方法展开研究,对现代城市电网展开“十二五”发展规划研究,探索考虑实用城市规划电网综合评价体系,并对城市智能电网规划做探讨。内容摘要如下：1、提出了实用城市电网综合评价体系,综合考虑电网安全性、可靠性、适应性、经济性、协调性和智能化水平,并使用加权和法综合评价各量化指标,使之适应于智能电网背景下的城市电网规划要求,对电网规划网架方案的选择起到了参考作用。2、针对城市电网实际,总结出负荷综合预测方法,并应用到余杭电网规划实际中,取得了较好的效果。3、以德国亚琛工业大学电力系统可靠性计算软件RAMSES为工具,对典型网架和规划网架进行了可靠性计算分析,在综合评价的基础上提出了110kV推荐接线模式,并应用于实际电网规划中。4、在建设坚强智能电网的背景下,对智能电网规划做出大胆设想,并根据余杭经济开发区实际情况,针对变电环节、配电环节、用电环节和通信信息环节做出初步规划。5、针对杭州市余杭区实际情况,从现代城市供电企业管理者的角度,制定了余杭电网“十二五”发展规划。更多还原

【Abstract】 Urban Power System Planning is a multi-objective, uncertainty, nonlinear, and multi-stage complex optimization problem, it is an important previous part of the Electrical Engineering. In the context of smart grid, advanced theory and technology planning is of great significance to improve the county grid level and the economic social benefits.The thesis conducts research on urban Power System planning theory and practical methods according to the modern city grid "12 Five Year Plan", tries to explore the practical consideration of the urban Power System Planning Comprehensive Assessment System, and the planning of city smart grid.Firstly, the thesis proposes a comprehensive evaluation system of practical urban grid, considering grid security, reliability, adaptability, economy, coordination and intelligence level, and uses the weighted sum method to evaluate the quantitative indicators, adapts the system to the requirements of urban smart grid,which has been the reference of Grid Program.In connection with the actual grid of the city, the thesis summes up load forecast method, and applies to Power System Planning of Yuhang, which has achieved good results.Using the calculation software RAMSES power system reliability from University of Aachen as a tool, reliability analysis for typical grid and computing grid is proposed. Based on the comprehensive evaluation, 110kV connection modes is also made, and then applies to practical Power System Planning.In order to building a strong smart grid, the thesis planns to make a bold vision for Yuhang Economic Development Zone, focusing on transformer link, distribution, electricity utilization and communication of the grid, a preliminary program is proposed.Finally, for the actual situation in Yuhang District of Hangzhou, from the perspective of the modern city power supply manager, a "12 Five Year Plan" Power System Planning of Yuhang is put forward.更多还原
