| With the gradual expansion of the development scale of Guang’an distribution network,the current manual and material resources cannot fully guarantee the operation and maintenance of some regional distribution devices,troubleshooting and emergency response tasks;miscellaneous response mode link emergency response current,the reaction time is too long.Therefore,it is necessary to improve the automation level of distribution network.In the Guang’an area of Guang’an,according to the distribution automation system according to the investigation of the current distribution facilities operation of Guang’an no longer run in good condition,the maintenance,protection and other aspects of the matter in the handling of the accident,due to continuous expansion of human distribution scale can make better operation of distribution network.According to the current development trend and the design requirements and construction scale of the rural distribution automation system in Guang’an,this paper explores the design and application of the distribution automation master station working system.This topic distribution network automation design according to the production and business premises of the cross power secondary system project "new design requirements,in view of the cross region distribution network design to achieve a comprehensive utilization of fiber,passive network communication access,realize the functions of feeder automation,information interaction of master station system.The first part of this article describes the basic theory of distribution network automation.This paper focuses on the skills and related knowledge needed to realize the automation of the network,and lays a solid theoretical foundation for the project exploration and discussion.The second part mainly is the power supply enterprise to build the network automatic control main station,according to the network automatic control the main station’s establishment plan to carry on the in-depth exploration.By conducting a large number of investigation,the situation of the distribution network is thoroughly controlled,and the next step is designed according to the reality of the distribution network in Guang’an countryside.In the third part,the automatic control sub-station and terminal equipment of the improved distribution network of Guang’an distribution network are mainly used.In-depth analysis of distribution network automation control station and terminal equipment improvement,including make break control station automatic control improvement,substation and power distribution control box of the automatic control of improvement and terminal equipment improvement of three parts,according to the current distribution network cross area improvement plan practice application Settings.The fourth part mainly carries on the network automatic control communication system design.In comprehensive analysis of waste in rural areas with netcom inquiry system plan,the first research the design of the automatic control communication system of distribution network,it mainly includes the following several principles: standard and divergent,avant-garde and sexual,economical and scientific,supports extensibility and compatibility,particularity and universality.The two communication methods of optical fiber and wireless network are analyzed.The fifth part completes the construction of the network communication platform.Plan to set up the communication server,based on completed to configure "polling" many times cycle task transfer calculation method can achieve both flexible and efficient purpose,eventually,by software and hardware can access all within the scope of their jurisdiction of cross power distribution terminal data,realize the target of cross region distribution network automation control. |
