文档介绍：现代住宅小区10/
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。

THE POWER SUPPLY SYSTEM DESIGN OF RESIDENTIAL
Abstract: The design of this residential area is the subject of the preliminary design of 10kV power supply system. The development present condition that contents and domestic and international power distribution that automates according 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 pare vs various scheme but get most suitable manual wiring through the residential load calculation, short circuit current calculation,the main electrical equipment to determine the model and parameters, reactive pensation design, lightning protection and over voltage protection.
The power distribution system step-down box-type substation with 10kV and 380V 2 a voltage, 10kV and 110kV substation side of the access bus 10kV, 380V electricity mainly for residential users.
Keywords: box-type substation, short-circuit calculation, reactive pensation, touchdown
