Abstract
Based on the related technical data of the New City Community in Sheng Si harbor, the electric power supply system was designed. Through the relevant design, the technology of civilian power supply system has been understood more deep. The main content was to design a 10kV electric power supply system of the residential district which consisted of a two 11-story buildings and seven 7-story buildings, and it mainly included the design of electric power supply systems, architectural lighting design, layout, lightning protection and ground. The specific requirements were load rating, power requirements, loads and power distribution equipment selection and laying of cable, design of lighting socket, lightning protection and grounding system. The results indicated that scheme of power supply system was viable. As improved of the living standards, the power consumption were more and more large, so the demand of electrical energy is put forward in higher requirement. The result of design is very important to promote the faster development of the power industry. According the relevant standards, specifications and industry standards, the content of design fully reflected the tightness of the industry and the professional of electrical characteristics in architectural design.
Keywords: power supply of residential district, civilian power supply system, 10kV power supply system, design of power supply system
