Project 3.3 Distribution Automation: Sensors and Condition Monitoring Prof Julian Meng,Prof Eduardo Castillo Guerra, U. New Brunswick www.smart-microgrid.ca Introduction: Project 3.3 • Development of smart wireless sensor networks for substation monitoring. • Test the sensor prototype modules under realistic operating conditions. • Deployment of low-cost re-configurable wireless sensors for monitoring overall microgrid health. www.smart-microgrid.ca Wireless Sensor Platform • IEEE 802.15.4 ZigBee based sensors (ISM frequency 2.4 GHz) are initially being considered. • Impulsive noise from partial discharge and sferic radiation (e.g. high current transients) makes a substation particularly challenging. • Previous research has shown that ZigBee sensors “can” work in this environment. www.smart-microgrid.ca Wireless Sensor Platform • Other protocols: DigiMesh, WirelessHART, 6LoWPAN, etc. “open vs proprietary”, “flexibility”, “security”, “energy consumption” • System Access: IEEE P1451 (re: Project 3.1, Dr. Michelson) • Generic re-configurable sensors to monitor: – Channel interference hot spots – Environmental conditions – Vibration, Shock – Faults – Circuit breaker status www.smart-microgrid.ca Wireless Sensor Platform Examples Embed’s sensor prototype development platform and Libelium’s Waspmote www.smart-microgrid.ca Way Forward • Test/measurement system for evaluating sensor network performance. • ZigBee simulation analysis -> noise limiting situation. • RF radiation measurements in a sub-station environment: NB Power and Saint John Energy. • Sensor packaging for outdoor environments –> simplicity in deployment (what is commercially available ???) www.smart-microgrid.ca Way Forward • Smart sensor configuration: = microcontroller + sensor module + transducers • Connections with other projects: Project 1.3 (Dr. Xu), Project 3.1 (Dr. Michelson), Project 3.4 (Dr. Farhangi) Thank you UNB Team: Dr. Julian Meng, Dr. Eduardo Castillo Guerra, Tristan Losier, AB Kar, Yandy Perez Ramos www.smart-microgrid.ca
