超高层建筑供配电系统设计

Design of Power Supply and Distribution System in Super High-rise Building

超高层建筑除了具有建筑高度高、规模大的显著特点,还具有业态多、智能化程度高等特点,其用电负荷密度集中,对供配电系统的安全性及合理性要求较高。从超高层建筑供配电系统特点出发,研究其设计难点,通过对电压选择、线路压降、功率损耗及年平均费用等进行研究和分析,在给定条件下通过计算比选出经济技术性较优的方案,以期总结出超高层建筑供配电系统设计的经验规律及合理方案,供同类型项目借鉴参考。

Modern super high-rise buildings have the characteristics of high structural height,large scale,multi-function and high intelligence.The power load density is high,and the higher security and rationality of power supply and distribution system are required.Starting from the characteristics of super high-rise buildings,the difficulties were studied in the design of power supply and distribution system.The voltage selection,line voltage drop,power loss and annual average cost were researched and analyzed.Through calculation and comparison,a more economical and technical scheme was selected under given conditions,in order to summarize the law of experience of the design of power supply and distribution system in super high-rise buildings.It can provide references for similar projects.
