FLOOD MONITORING OF DISTRIBUTION SUBSTATION IN LOW-LYING AREAS USING WIRELESS SENSOR NETWORK
ABSTRACT
In this paper, a novel wireless sensing network node with 2.4 GHz communication and flood detection with 0.02 volt/mm sensitivity is presented for flood monitoring of distribution substation of electrical utilities in low-lying area.
The sensor node is as compact as 8 cm × 6 cm and a low power consumption of 860 mW. When a liquid level detector detects an abnormal water level near the substation room, a signal can be transmitted in 115 kbps via a Zigbee module to a control center. It may reduce the risks of damage of the substation and subsequently ensure the power supply safety.
