 ABSTRACT:
   

 Electricity is one of the most important requirements of civilization, without which various indispensable applications will bind to bring a standstill.As the demand for electricity is increasing nowadays.So electric utilities prefer load shedding when demand exceeds the supply.Thus in a distribution system, it needs to be precisely measured for a specific period of time. ’Automatic Load Shedding System‘ is reliable and effective load shedding technique that takes over the manual task of switch ON/OFF the electrical supply with respect to time.It uses real clock interfaced to the 8051 family microcontroller. ’Automatic Load Shedding’ system will provide real and competent load shedding techniques such that distribution substation can be monitored and load shedding from one particular place.



DESCRIPTION:

        The conventional system of operating electrical loads manually requires human involvement wherein a person needs to go there and press the switch to turn the loads on or off correspondingly.The proposed system is enhanced to control the electrical load by the real-time clock(RTC) to keep it track of time to switch on or off the load accordingly.
The proposed system uses a microcontroller of the 8051 families and a rectified power supply.The real-time clock is interfaced to the microcontroller for maintaining an accurate time. A matrix keypad is used for storing the information. The loads are controlled by a relay driver which is connected to the microcontroller. A seven segment is interfaced to the microcontroller for displaying the time.
This system allows the user to enter the prescribed timings at which the user wants to switch the load as per the requirement through the keypad. Such type of data is stored in the microcontroller. The microcontroller continuously reads the time from the RTC.Whenever the time is matched to the stored time, then microcontroller gives commands to the corresponding relay to turn on or off the load as per the program and also displays the time on the 7-segment display.
