Study On The State Of Active Intelligent Monitoring And Fault Of Judgment Of The Nanping Distribution Network

At present,the 35kV Simple Distribution Substation almost has no ability to remote control and no single of the emergence of the single phase grounding.Due to the lack of integrated automation and protection configuration results in Simple substation in the event of a single phase when no signal losses,it is a long time and difficult for the distribution line fault to detect the troubleshooting points.According to the parent company requirements and the requirements of modern distribution network construction projects,Based on the research at home and abroad,this paper has developed a distribution network in the state of the intelligent system monitoring and fault active judged,aimed at improving the tone distribution efficiency,reduce the workload of dispatchers and shorten outage Published improve power supply quality services.Based on the analysis of the distribution network troubleshooting needs and the actual situation Nanping grid,the overall scheme of distribution network running status monitoring and fault smart grid initiative Nanping judged was designed in this paper.With the development process of the system,First,the distribution network is designed to run on Intelligent Monitoring System:the GPMS interactive system interface achieves a model and graphic GIS of the new 35kV simple distribution substation network to import;The development of new data collection,data processing,hierarchical signal partition display,light plate display and alarm processing module,intelligent monitoring and control of the new 35kV simple distribution substation;Communication and interaction based on webservices,the development of DMS systems and information collection system interface enables real-time access and well-designed test called variable data;The active fault network operation system judged was designed and implemented With the developed failure logic judged based on power outage,outgoing switch current transition,fault indicator flop,FA result,bus and station blackout,Public variable phase,realizes the different types of active fault judgments and information dissemination.In order to improve the system,judged query FIG cross flags,judged indicator,analyzing section extracts,SMS modules and other tools are developed,The distribution network operation fault system was judged practically,as well as to improve the stability and reliability of the system operation.According to the actual needs of the regulation of operating personnel,Through a variety of applications to build data acquisition and processing,feeder automation,network topology analysis,load flow,fault judged,WEB publishing capabilities to completed the artwork interacts with GPMS system,and production system with well-designed variable data interface data interoperability from the practical point of view.And now,the system used in the distribution network of the Nanping supply company of the State Grid has been through the practical work of the distribution automation acceptance of the State Grid...
