This project aims to create a system that detects synchronization failures in power grids due to frequency or voltage deviations, preventing potential blackouts. Using an 8051 microcontroller and various electronic components, the system alerts operators when conditions exceed acceptable limits, allowing for preemptive measures. Future enhancements may involve integrating power-electronic devices for more advanced detection methods.

GRID SYNCHRONISATION FAIL DETECTION ON SENSING
FREQUENCY OR VOLTAGE BEYOND RANGE
ABSTRACT
The project is designed to develop a system that detects synchronization failure of any external
supply source to power grid on sensing the abnormalities in the frequency or voltage.
There are several power generating units connected to the grid, such as hydel, thermal, solar, etc
, to supply power to the load. For any deviation of the voltage or frequency from the acceptable
limits of the grid, it becomes mandatory that the same feeder should automatically get
disconnected from the grid, which by effect is termed as islanding. This prevents large scale
brown out or black out of grid system. It is preferable to have a system that can warn the grid in
advance so that alternate arrangements are kept on standby to avoid complete grid failure.
This system is based on a microcontroller of the 8051 family. The microcontroller monitors
under/over voltage being derived from a set of comparators. As regards the frequency ,since the
mains supply it cannot be changed, the project uses a variable frequency generator (555-timer)
for changing frequency, while a standard variac is used to vary the input voltage to test proper
functioning of both these parameters of the project. A lamp load (indicating a predictable
blackout, brownout) is driven by the microcontroller in case of voltage/frequency going out of
acceptable range.
Furthermore, this project can be enhanced by using a power-electronic device to isolate the grid
from the erring supply source by sensing cycle-by-cycle deviation for more sophisticated means
of detection.
