On-line Monitoring Device in Substation Based on the Technology of CAN Bus and ARM Microprocessor
A multi-layer distributed on-line monitoring system of substation is designed in this paper.The on-line monitoring IED(Intelligent Electronic Device) is placed in each bay to uninterruptedly monitor and control primary devices per bay.The IED is based on CAN filed-bus and ARM microcontroller.CAN filed-bus is introduced for internal communication and ethernet for external communication with substation computer.The presented device is excellent in the ability of real-timing
