ABSTRACT:
In India the production of electricity is mostly depends on hydroelectric power plants. But
the lack of rain and water these power plants cannot meet the requirements. So an effective
option is to control the electricity by load shedding. The conventional method is switching off
one line for some time, and after turning ON this line the turning OFF other line.
In this project we are controlling ‘2’ number of relays (According to the availability of ports in the
MC) that are connected directly to the power lines. And these relays are driven by a micro
controller unit. In this micro controller unit we are employing the desired delay (Line off time),
with the help of GSM module say suppose it is 30 min., we have to turn off line 1. for 30 min and
after 30 min. again we have to turn it ON and turn OFF line 2. for 30 min and so on. We should
program the micro controller according to above-mentioned idea. And one more thing is, the
user should be able to adjust the delay. That is, the system should accept some inputs given by
the user. That is, we are employing one GSM mobile and an LCD to enter the desired delay and
once the delay is entered then the system will work with that delay till the next change given by
the user.
