IOT-Based Monitoring and Controlling of Substation Parameters

Inevitably, electricity contributes to the development of the country. PLCs and SCADA systems are used to automate substations according to conventional methods, although this technology is incredibly expensive for a tiny substation. In order to automate a modest 11 kV substation, this study employs low-cost automation methods based on cutting-edge IoT innovations and embedded processors like the Raspberry PI. Using Raspberry PI, the smart substation is a modern automation solution that allows for the global control of device status and the main theme of the project is to control, monitor, and protect the power system network in the substation. The PZEM module, which is connected to a Raspberry PI (RPI), senses the parameters that need to be tracked in this situation. Data is delivered to the RPI, where it is analyzed so that tripping activities can occur. When the current sensor-measured value is processed with the help of predetermined programming in Raspberry PI, it will enable the relay to close, cut off the supply, and send a telegram alert to the authorized engineers. As the sensors identify the current or voltage values exceeding or falling behind some fixed threshold value.
