文档介绍：摘 要
在电力系统中，配电系统是承接发输电系统和终端用户的重要环节，其运行水平直
接影响到广大用户的用电感受，体现了电力系统对用户服务质量。随着我国社会、经济
的快速发展，电力用户对供电质量，特别是供电可靠性的要求越来越高。停电对许多用
户可能造成难以估量的损失。电力企业面对供电可靠性的挑战与压力，一方面不断改善
管理水平；更要加大投入，从技术手段提高配电网运行水平。
本文结合汕头配电系统的实际，对配电网自动化的规划问题开展研究，对配电网可
靠性评估、分段开关优化配置等问题深入探索。在可靠性评估中，改进了故障模式与后
果分析方法，以开关类设备为分界点对配电网络的拓扑结构进行划分和归算，简化了可
靠性评估的计算量。在此基础上，对分段开关优化配置问题进行建模，以综合经济性成
本最优为目标，建立数学模型；并采用改进的遗传算法求解。在辐射型网络和环形网络
的算例中，均取得了较好的优化结果。该模型和优化算法在汕头地区配电自动化系统的
规划中得到了应用，研究成果具有较好的理论意义和实践价值。

ABSTRACT
Abstract is written in times new roman.
The power distribution system is an important link between power generation, transmission
system and the terminal users. The operation of distribution system directly affects the quality
of electric energy and service. The users demand its power supply with higher quality and
reliability as the rapid development of society and economy. Blackout might cause
incalculable losses. The electric power enterprises should improve the technology of
management and operation in the face of challenges and pressures.
The planning of distribution automation system is studies in thesis combining the practice of
Shantou distribution networks. The reliability evaluation method and optimal allocation of
sectionalizing switches are researched and introduced in detail. The failure mode and effects
analysis (FMEA) method is improved by division to reduce calculation burden. The switches,
breakers and fuses are topology dividing point of distribution networks. The allocation of
sectionalizing switches is modeled as optimization problem aim for best comprehensive
economic cost. The improved genetic algorithm is employed to solve it and gets optimal
solution in simulation networks. The application in Shantou distribution automation planning
shows the theoretical significance and practical va
