现代住宅小区 10/0.4KV 供电系统设计 摘 要 本次设计的课题是住宅小区 10kV供电系统的一次设计。依据配电自动化的 内容和国内外配电自动化的发展现状，本着“安全性、可靠性、经济性以及易维 护性”的原则，完成了本次设计。 以我国现行的各有关规范规程等技术标准为依据， 再根据任务书提供原始资 料，参照有关资料及书籍，对各种方案进行比较而得出最为合适的方案。这次设 计的主要内容包括小区负荷的计算， 短路电流计算， 主要电气设备型号和参数的 确定，无功补偿设计，防雷保护装置的设计。 供电系统采用的是降压箱式变电站， 具有 10kV和 380V两个电压等级， 10kV 一侧接与小区旁边经过的 110kV变电站的 10kV母线， 380V 主要用于小区用户及 小区公共场所的用电。 关键词 ：箱式变电站，短路计算，无功补偿，接地 I THE POWER SUPPLY SYSTEM DESIGN OF RESIDENTIAL Abstract: The design of this residential areais the subject of the preliminary design of 10kV power supply system. The development presentcondition that contents and domestic and international power distribution that automatesaccording to the power distribution automate. The power supply system designed is very important, if the system is broken, the entire residential area will affect the power supply, so the high reliability requirements. Therefore, the design must take into account the power system security, reliability and economy. With our country each current relevant specification regulations etc. technique standard is basis, again provide original data according to the task book, according to interrelated data and book, carry on compare vs various scheme but get most suitable scheme.This manual wiring through the residential load calculation, short circuit current calculation,the main electrical equipment to determine the model and parameters, reactive power compensation design, lightning protection and over voltage protection. The power distribution system step-down box-type substati
