| With rapid development of economy in Qingyuan City, Qingcheng grid as Qingyuan City power supply network, with the increase of the electricity, power quality problem has increasingly become focus of power user. Qingcheng district power grid is located in the northern Guangdong mountains, fault prone, fault finding difficult, a long line of overhead hybrid line more. For the rapid development of the Qingcheng district power grid in order to adapt to the economic, Qingcheng power supply bureau must according to the characteristics of the area, on the line of feeder automation retrofit upgrade, the Qingcheng district power supply reliability has been greatly improved. But the distribution network is becoming more and more complex, so it is necessary to improve the technical and economic index of the urban distribution network. A more comprehensive analysis of the status quo on Qingcheng district distribution network, and the design goal.This paper carries on the analysis to the importance of distribution network automation construction, it can improve the reliability of power supply, improve the power meanings of aspects of that quality, improve the economic benefit of power supply enterprises, improve the management level and service quality, put forward importance and urgency of construction of distribution automation. At the same time, the analysis distribution automation technology in the domestic and foreign development advantages and disadvantages, the focus of Qingcheng district distribution network status were a comprehensive analysis, and combining with the actual situation in Qingcheng district distribution network operation, a detailed plan on the construction of distribution automation is related to a equipment, automation system design, fault isolation and location of. The overall design and construction model of distribution network automation system is established, and the requirement of operation and maintenance management of distribution network automation equipment, equipment index evaluation and monitoring mechanism are established..The establishment of Qingcheng district distribution automation master station system fully meets the requirements of the southern network integrated grid intelligent operation system of construction technical specification "and follow the principle of OS2 standard" integration, modularization, intelligent design. And safety production management, asset management system, with intensive adjustment, GIS document management, measurement automation, customer service management automation system of data sharing and application through the service bus, process management, improve the efficiency of the distribution network automation application, improve enterprise management efficiency.After the implementation of the construction of distribution network automation work, Qingcheng district distribution network through the implementation of distribution automation pilot reform and more than a year of operation practice, summed up for more than a year to all aspects of the comprehensive index and operation experience. The indicators show that made ver y good effect, greatly enhance the reliability level of Qingcheng distribution network, demonstrates the construction of distribution automation mode is feasible and effective. |
