Research On The Application Of Distribution Network Automation System In Central Area Of Tangshan

In order to improve the power supply reliability, to meet the demand of customers, andto ensure the quality of power supply, it is important to realize the automation of distributionnetwork. The city of Tangshan has the rapid economical development in recent years, andelectricity sale has ranked the fourth among the nation cities. In order to cope with the risingdemand for electricity, it takes hundreds of millions yuan for distribution networkinfrastructure annually, in which a large proportion used for distribution network automationconstruction.Based on the study of the law in distribution network automation system development athome and abroad and the situation of Tangshan area, a method for distribution networkautomation to achieve high quality operation is proposed. To realize distribution automationnot only depends on the monitoring system of distribution network, but also the more strongand reliable net, the first and second devices to distribution automation system can improvethe reliability of power supply target.Based on the central area of Tangshan city power distribution network structure, loadtype, type of equipment, technical parameters of the production line, from detailed, accuratedata, the existing distribution network automation system master station, sub station,communication system evaluation, the distribution network automation system design isprovided in the required data and experience.According to the research of city distribution network automation system, to focus on thedesign of distribution network automation to intelligent power grid construction of nationalkey projects--Caofeidian Industrial zone. Distribution automation area city center focus onold time equipment modification and optimization, to be equipped with automatic terminal,which is suitable for distribution automation operation requirements; and a kind of newCaofeidian Industrial Zone, a grid infrastructure is better, in the distribution networkautomation construction in a more prominent high starting point, high standard, and strive to acomprehensive intelligent investment construction improve the distribution network.Through the analysis of a space truss structure present situation, the target of the reformand initial design is proposed; through the analysis of network structure and load condition,and the technical standard of distribution automation construction, the guidance on thecorresponding primary equipment automation is provided. The results have been applied inthe distribution automation system of Caofeidian Industrial Zone of purchasing and erectionwork. The construction design data generated according to the refinement has been used inthe actual construction, and the design of Caofeidian eco city distribution network planningongoing as reference and guidance.
