文档介绍：供配电系统是电力系统的电能用户。电力系统和供配电系统的概念、电力系统的额定电压、电力系统的中性点的运行方式、电能的质量指标和电力负荷等基本知识是做供配电技术所必需的。做好供配电工作,对于促进工业生产、降低产品成本、实线生产自动化和工业现代化及表彰人民生活有着十分重要的意义。
此论文对学生公寓进行了负荷分析和计算,同时对负荷进行了无功功率的补偿。在这个基础上又比较分析了宿舍楼配电系统的接线方案,确定接线方案之后根据技术规范进行了电气主设备的选型。
对于主电气设备的选型主要包括主要高压开关柜(包括高压断路器、高压负荷开关等)的选择、主要低压成套开关设备(包括低压熔断器、低压断路器、隔离开关等)的选择。并于最后做了各主要电气设备的校验,绘制了校验表。
此论文最终完成了学生公寓供配电的设计,完全能够满足学生生活对于电力的需求,但是针对宿舍的防雷与消防保护方面并未太多涉及,也是本篇论文的不足之处。

ABSTRACT
Power supply and distribution system is the power user of electric power system . The concept of the power system and power supply system, the rated voltage of power system, power system’s operation mode, power quality indices and power load and other basic knowledge are necessary for power distribution a good job of distribution, for the promotion of industrial production, reduce product cost, solid production automation and industrial modernization mend people life is very important.
This pleted the load calculation and analysis of the student apartmen , at the same pleted pensation of reactive power.
On this basis, this pletes some wiring schemes and determines the wiring scheme according to the technical specification of the main electrical equipment selection. The selection of the main electrical equipments mainly includes the main high voltage switch (including high voltage circuit breaker, high-voltage load switch and so on) selection, main low-voltage switch equipment (including low-voltage fuse, low-voltage breaker, isolating switch) selection. And finally made the main electrical equipment calibration, and drew the list of checking.
This paper pleted the power distribution design of the student apartments, fully able to meet students demand for electricity. But it didn’t involve the dormitory lightning protection and fire protection so much, this is is also the deficiencies.
