| Abstract: |
| A layered and distributed power quality monitoring platform is designed for electrified railway based on the distributed software architecture.The distributed platform adopts 1 -to -N management,mainly comprising control center,substation and communication channel.Its power quality index monitoring,including harmonic,voltage fluctuation and flicker,three -phase unbalance,power factor and so on,observes the newest national standards,and the examination methods may follow the redaction of national standards in time.Embedded Internet technology is adopted to transparently support multiple communication protocols.The substation is mainly composed of a three-phase power quality monitor with USB port,which measures the power,energy and three-phase power quality data,including harmonic,transient,sag / swell,power factor,inrush,etc.The platform is open to operators and the monitoring points can be expended.SQL Server2000 database management system is adopted.The designed power quality monitoring platform is well operating in Qingdao -Jinan electrified railway,covering several traction substations. |
