摘要:电网的规划、设计、建设规范化和标准化，保证了电网安全稳定运行，提高供电可靠性，达到优化电网结构、保证电能质量、降低电网损耗，同时提高了电网经济性和劳动生产率，满足用电负荷不断增长的需要，建设与都市国民经济发展相适应的现代化电网。
本论文主要进行对中低压配网规划的网架优化和可靠性分析这两方面内容的研究分析。编制电网规划，从调查研究电网现状入手，分析负荷增长规律，解决电网薄弱环节，优化电网结构，提高电网的供电能力、适应性和自动化水平。通过对两个供电所的10KV 线路的总体分析，了解了线路的主干长度情况，接线模式分析，线路的重、过载情况等等，对一些具体线路进行可靠性计算，通过对年故障停运率、平均停运持续时间、年平均停运时间的计算，评估线路的可靠性......通过对这些线路的研究，得出了线路现状所存在的问题，并对部分提出改造方案，也根据区域的负荷预测，提出了未来几年的电网规划，做出资金预算，预计改造后的效果。
电网规划要做到近期与远期相结合，新建与改造相结合，实现电网接线规范化和设施标准化。在电网运行安全可靠和保证电能质量的前提下，达到电网建设的技术先进和经济合理的目标。
关键词：配网规划；网架优化，可靠性
Abstract:To make the network planning, design, construction and standardization,guarantee the safe and stable operation of the grid, improve the power supply reliability,optimize network structure, the guarantee quality, reduce the energy loss of power grid,efficiency and productivity goals, electricity load increasing, national economic development and urban construction adapt to the modern network.
This thesis were on the low-voltage grid distribution network planning optimization and reliability analysis of these two aspects of the research. The preparation of network planning, network status from the research, analyzes laws of load growth and solve network weaknesses, optimize network structure and improve the power supply capacity, adaptability and automation. Powered by two 10KV lines by the overall analysis, to understand the situation the length of the trunk lines, wiring pattern analysis, line weight, overload situations, the reliability of the calculation of specific lines, through years of failure outage rate, average outage duration, the calculation of the average outage time to assess the reliability of line ...... research on these lines, draw the line status of the problems, and part of the modification program, also on the regional load forecasting is proposed network planning the next few years to make capital budget is expected to effect after the modification.
Grid planning should be combined with the forward recently, new combination, and realize network wiring standardization and standardization of facilities. In the network safe and reliable operation, and ensure the quality of electric power construction premise, reach the advanced technology and the economic and reasonable target.
KEY WORDS：distribution network planning; network optimization; and reliability
