Design Of Commercial And Residential Complex Intelligent Power Supply System

The background of paper is commercial and residential complex in a city.This paper calculate the large number of electric equipment,large load,large type,reserved load,large number of units,complex distribution lines and so on.According to classification of electricity of the building,select such as the appropriate transformer reactive power compensation,power cable,power distribution room layout and design of lighting protection and grounding,then design the power supply system building.When the preliminary design of power supply and distribution,the design of power supply and distribution system has been completed.If electric equipment and power units cannot by determined,then calculation of load power per unit area.the calculation load is classified,the total active power,reactive power determined.The suitable transformer and reactive power compensation device are selected to check the power quality.This paper select the appropriate high and low voltage,determine the connection and power supply mode accord to the working conditions.According to the grade,evenly distributed on the low voltage switch cabinet,then the power supply reliability is ensured.Designed The lighting protection and grounding system.The designing of high-rise public buildings power supply is more complex then that of residential and plant power supply and distribution systems.
