Intelligent Community Of Electrical Enngineering Design And Practice

In recent years, with the development of technology and people's living standards continuously improve, more and more intelligent community emerging. These communities are characterized by complex function and advanced design, so the electrical design is put forward higher requirements.The content of this article come from the practice of engineering design. The design project is an intelligent community and it located in Deyang City. In this paper, the design of this project based on the actual characteristics of the buildings, and learned the newest technologies, I learned so much to design a reasonable, simple, and reliable electrical system. First of all I designed the10/0.4kV power distribution system, through load calculation and reasonable load forecasting we can choose reasonable electrical equipment, such as power distribution cabinets, switch equipment; furthermore I use the automation technology in the distribution system of the community. The power distribution system automation application to plot the distribution levels, the power distribution system is often used for large-scale distribution, but I designed a system that used to the small area, it includes two parts, control center and measurement instrument, which improve intelligence of the community and operation level. And then I designed the fire alarm and fire control linkage system. Because the region is narrow, once the fire occurs then will cause a great loss. So I designed a system that can alarm automatic and at the same time it can control equipment, when the fire occurs, it can control the equipment such as fire pump, exhaust fan, these equipments could be controlled for fire fighting. At last I designed a system of lightning protection, it is different with the traditional technology, because it could protects the buildings completely, and especially against lightning wave electromagnetic interference protection of a special design, the lightning protection device to form a system.The community of the first phase of the project has been completed by the residents in, through the operation of electrical system, it works stable and no fault occurrence, various indicators was accurate, the result show that is to meet the actual needs.
