Abstract: Since the power systems are highly nonlinear, huge and complex, there will be a possibility of interruption of lines feeding to substation due to line faults, these results in overloading of other lines feeding to sub-station resulting in cascaded tripping. To avoid cascaded tripping due to overload of lines it is necessary to monitor the status of incoming & outgoing lines& to trip the outgoing lines based on the withstanding capacity of incoming lines.The purpose of this project is to monitor the status of incoming & outgoing lines using Microcontroller(8051) & to avoid cascaded tripping of incoming lines by initiating tripping of least priorityutility outgoing lines in order to maintain load balance and hence there will be no overloading and the system works efficiently. The real time value of Frequency and the lines which are tripped will be displayed on the LCD.
