【正文】 Power supply system of highrise building design Abstract: With the continuous development of city size, more and more highrise buildings, therefore, highrise building electrical design to the designers had to face. In this paper, an engineering example, describes the electrical design of highrise buildings and some of the more typical issues of universal significance, bined with the actual practice of an engineering solution to the problem described. Key words: highrise building。 electrical design。 distribution。 load calculation 1 Project Overview The mercial plex project, with a total construction area of 405570m2, on the ground floor area of 272330m2, underground construction area of 133240m2, the main height of 99m. Project ponents are: two office buildings, construction area is 70800m2, 28 layers, the standard story is . 2 Load Calculation 1) Load characteristics: electric load, much larger than the national civil engineering technical measures Large 120W/m2 indicators, especially in the electricity load more food, and different types of food and beverage catering different cultural backgrounds also high. 2) the uncertainty of a large load, because the mercial real estate rents are often based on market demand, and constantly adjust the nature of the shops, making the load in the dynamic changes. 3) There is no specification and technical measures in the different types of mercial projects refer to the detailed parameters of the shops, engineering design load calculation in the lack of data, in most cases to rely on staff with previous experience in engineering design calculations. Load the selection of parameters: for the above problems, the load calculation, the first developer of sales and good munication, to determine the form of layers of the forms and nature of floor area, which is calculated on the basis of electrical load basis。 followed to determine parameter index within the unit area of shops is also very important and plex because there is no clear indicator of the specification can refer to。 and different levels of economic development between cities is not balanced, power indices are also different。 will be in the same city, different regions have different consumer groups . 3) the need to factor in the choice: parameters determined, the need for load calculation. Need to factor monly used method, the calculation will not repeat them. Need to explore is the need for coefficient selection, which in the current specifications, manuals and the unified technical measures is also not clear requirements, based on years of design experience that most end shops in the distribution or level within the household distribution box with case Kx generally take a while, in the calculation of the loop route to take to , the distribution transformers in the substation calculations take to . 3 substations set Load calculation based on the results of this project the total installed capacity of transformer , after repeated consultations with the power pany, respectively, in the project in northern, central and southern three sections set the three buildings into three power substations, 1 set 6 sets transformer substation, take the
