Abstract:

With the ever growing demand for electrical energy across the world, we, as electrical engineers, are put in a state of responsibility to conserve the energy as Energy Saved is Energy Generated. A sincere attempt is made in this work to conserve the electrical energy, by designing an autonomous system that monitors the inflow of the electrical energy, limits the consumption so as to comply with the maximum load constraints and transfers the critical loads to captive / co-generation systems for our campus. In the present system, the monitoring and control is done manually which is very hassle process, leading to unnecessary tripping of loads across entire campus. In the proposed system the current, voltage and the frequency are measured and monitored continuously by a processor through appropriate sensors. Using these data, other information such as KVA, KVAR, KW and power factor are estimated by the processor. Once the any of the above parameter exceeds its threshold value, the processor generates control signals to actuate the respective relays to trip-off the connected loads hierarchal manner. In addition, if the EB supply is tripped-off completely, the processor automatically switches the generator on and connects only the essential loads to the generator. Upon the restoration of the EB supply, as per the predefined precautionary measures, the loads are shifted back to EB line and the generator is set to idle condition. Atmega 328 processor based Arduino-UNO is the heart of the proposed system which is supported by required interfaces for both data acquisition and control. The proposed system has been fabricated and tested. The performance is found to be satisfactory.
