Internet of things based sensing system for substation automation in smart grid environment

摘要

Substation Automation is a key concept in Smart Grid Technology. The present work proposes an Internet of Things (IoT) based system for the monitoring, visualization, storage and analysis of sensor data in an easy, cost effective and reliable manner. MQ Telemetry Transport (MQTT) protocol is used to communicate and transfer data between different sensor nodes using Raspberry Pi 3 as the MQTT broker. The sensor nodes are capable of wirelessly transferring the sensor data using an Arduino Uno and ESP8266. The sensor data can be conveniently accessed by any device on the network from the MQTT broker by subscribing to it. The given sensing system intends to complement and enhance the capabilities of the present substation automation environment. It incorporates the possibility of remote accessibility and better data analysis of the sensor data in the Substation environment. An Arduino sensor node with wireless capability has been tested and reported as a part of the ongoing implementation of the system which will be described in further works.
