Research on Intelligent Distribution Automation Technology
The current comprehensive intelligent management system for power grids in power companies,namely the integrated distribution network automation,is discussed.The system adopts feeder terminal unit(FTU)and com-munication network to realize feeder automation,which is mainly divided into centralized intelligent feeder automation system and distributed intelligent feeder automation system.The centralized intelligent feeder automation system re-quires the installation of a main station system,FTU,communication lines,load switches with the ability to cut off short-circuit currents,SCADA systems,and advanced distribution applications(PAS).Topology analysis,load es-timation,power flow calculation,short-circuit current calculation,line loss analysis,reactive power optimization,network reconstruction,and short-term load forecasting have been conducted on the distribution network.The aim is to combine modern electronic technology,communication technology,computer and network technology with civil power equipment to organically integrate the detection,protection,control,metering,and power supply department management of the civil distribution network under normal and accident conditions,and improve power quality.
