IOT BASED POWER MONITORING AND MANAGEMENT SYSTEM OF A DISTRIBUTION SUBSTATION

Abstract

Remote monitoring and control of the substation is a critical issue for the power or energy management department, which is typically done manually or with the help of SCADA system. We proposed a system that is low cost, user friendly, and works in auto mode to avoid labor involvement and system loss. With the emergence of the internet and the computational era, a smart monitoring and trustworthy controlling system over the complete sub-station is extremely desirable, which may be accomplished by implementing Internet of Things (IoT) technology. Our own developed website is used in this paper as an IoT analytics platform service which lets the programmers collect, visualize and analyze incoming data streams to the cloud. The collected data is sent to the website, create instant visualization of live data related to the monitored station. We can monitor the power factor, supply voltage and total load current through this automation system. Engineers in charge of the station may monitor the progress of the station's operations from anywhere in the world using any internet connected device - a computer or a smartphone. Actually we want to distribute the load properly according to our load capacity and according to the importance of the place. There are three areas in our project based on different types of priority. When load demand increases more than available energy, automatically load shedding happens to the lesser priority areas. Here we have given first priority to hospitals followed by second priority to industrial areas and third priority to residential areas. The system applies a safety feature to completely close the power station in the event of a serious condition such as a fire. So, our main objective is reliable and safe power distribution properly where the entire system will be controlled through automation system.
