Detecting Power Grid Synchronization Failure on Sensing Frequency or Voltage Beyond Acceptable Range

Abstract

This main objective of this paper is to build a simulation model of a system ,in proteus software ,which monitors voltage and provides a breakpoint by low and high voltage tripping mechanism that keep away from any damage to the load, Majority of industrial and domestic systems would encounter fluctuation in the AC mains supply. The chance of damaging electronic devices is very big as they are quite sensitive to these fluctuations. So, Tripping system that avoids any damage to these loads is necessary. This system has tripping mechanism that monitors the input voltage and trips according to limits provides. The system delivers an error as soon as the input voltage falls out of the window range. This system is also configured with an alarm that goes on as soon as tripping takes place.we use mainly microcontroller, comparator and led display for detection of over/under voltage and frequency and we also use GSM to send notification in web terminal.
