摘要
以某高校综合实验楼为背景,完成变配电系统设计、变电所设计。首先,根据实验楼的供电要求及负荷分级,计算了负荷、短路电流和无功功率补偿,确定了本工程的供电电源和供配电系统一次接线;其次,根据负荷选取变压器和电气设备,通过短路电流计算值整定和热稳定校验进行了验证;再者,运用BIM进行了低压设备和高压设备的布置;最后,完成了操作回路等二次回路设计。参照最新的规范,运用合理的供配电设计,降低建筑电气在变配电中的能耗。通过对负荷归类分析,设备选择校验,从而完成变配电系统设计,保证供配电的可靠性。
Take a university comprehensive laboratory building as the background.The design of power supply and distribution system,substation for buildings has been completed.Firstly,according to the power supply requirements for the laboratory building and load classification,load,short circuit current and reactive power compensation has been calculated.It determined power supply of the project and primary connection of power supply and distribution system.Secondly,it arranged lower pressure equipments and high pressure equipments by BIM.Finally,the paper completed those secondary circuits such as operation circuit.This project refered to the latest specifications,reduced the energy consumption of supply and distribution system.By mean of the analysis of load,selection and verification of equipments,the design of power supply and distribution system completed and the reliability of power supply and distribution guaranteed.
