    Abstract：The electrical design for super-large convention and exhibition projects is introduced in such aspects as the classification of load class，analysis of load density，selection of backup power supply，setting of power distribution room of pavilion，setting of electromechanical pipelines，application of high-ceiling LED lighting in pavilions，analysis of main pipeline trench size，application of photovoltaic power generation on pavilion roof，and intelligent booth box on the ground. This paper compares the advantages and disadvantages of setting of main electromechanical route of exhibition at different positions from the aspects of technology and economy，analyzes the application of high-ceiling LED lighting in pavilion buildings，and introduces the advantages of photovoltaic power generation system in convention and exhibition buildings and the application of intelligent booth box.

    Key words：super-large convention and exhibition center；load density；transformer shutdown；exhibition lighting；main electromechanical route；pipeline trench size；pavilion photovoltaic；intelligent booth box

  摘 要：从特大型会展中心的负荷等级划分、负荷密度分析、备用电源的选择、展馆配电室设置、机电管线路由设置、高天棚LED照明在展馆中的应用、主管沟尺寸分析、展馆屋顶光伏发电应用、地面智能展位箱等方面介绍大型会展项目电气设计。从技术、经济方面对比展览机电主路由不同位置设置的优缺点，分析LED高天棚灯具在展馆建筑的应用，介绍光伏发电系统在会展建筑中应用的优势，以及智能展位箱的应用。
