Abstract:

This project aims to build a system that can detect abnormalities in voltage or frequency in order to detect power sync failures. Real-life energy grids include Hydro energy sources, thermal, solar etc. connected to sync to run the industry. These sources must be enabled in accordance with grid rules. These rules include the difference in voltage and frequency within certain limits. Deviations from these limits should result in that data source being disconnected from the grid immediately. This is known as islanding. This is used to avoid large brown or dark discharges from the power grid. Our system is designed to warn the grid in advance of power failure so that the grid can use other backup data sources if needed to avoid a complete power failure. Our system demonstrates this using the 8051 family microcontroller. The MC is used to find the electrical power and frequency in a set of comparators. Since the frequency can vary, a frequency generator (555 timer) is used for this purpose. A standard load / lamp is used to indicate a predicted power failure or power failure in the event of a voltage / frequency variation.
