Monitoring & Controlling of Substation Using IoT in Distribution Power Grid

A new smart voltage and current monitoring system (SVCMS) technique is proposed. It monitors a single phase electrical system using an Arduino platform as a microcontroller to read the voltage and current from sensors and then wirelessly send the measured data to monitor the results using a new Android application. The integrated SVCMS design uses an Arduino Uno as the microcontroller to measure the results from voltage and current sensors and then send this data, after calculation, to the Android smartphone device of an end user using Wi-Fi module. The Arduino Uno controller and ESP8266 W-Fi module are a cheap microcontroller and wireless device, respectively. The new Android smartphone application that monitors the voltage and current measurements uses the open source MIT App Inventor 2 software. It allows for monitoring some elementary fundamental voltage power quality properties. The system also calculates frequency and power factor of line using zero crossing detectors and from calculation of voltage and current respectively.
