Abstract

Abstract: A new intelligent electronic device(IED) for switch cabinet comprehensive on-line condition monitoring based on Internet of Things and IEC 61850 standard is designed for the substation spacer layer. The device adopts double cpu structure of ARM+DSP as hardware core with VxWorks and C language for its software development platform; embedded with ICD files meeting the IEC 61850 standard, the IRIG-B code is used for synchronous clock. Through the Zigbee and RS485/RFID/CAN, the data transmission from the sensors to the monitoring units (the process layer) is realized, and the communication with the monitoring center (the substation control layer) by the optical fiber is conformed with IEC 61850. Moreover, the monitoring system framework, the IED’s hardware, software platform and IEC 61850 information modeling are designed. The practical operation shows that the IED can fulfill the functions of signal remote- collection, analysis, transmission and monitoring in all status and integrate them into the synthetical diagnosis on the information platform.

Key words: smart substation, high-voltage switch cabinet, IEC 61850, comprehensive on-line monitoring, intelligent electronic device
