Design of Uninterrupted power supply under faulty condition
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryUninterrupted power supply are power supplies that can switch over to solar batteries before connecting to generator when power outage occur. Multiple devices can be plugged into the uninterrupted power supply similar to a power bar, and this system provides such functions as surge protection, noise filtration and priority base switching.
Project ObjectivesAn uninterrupted power supply is a device that allows load to keep running even the supply is not coming. Before going to generator and get stable condition load will shift to the solar backup.
Project Implementation Method- First we finalize the calculation of hardware.
- Then we assemble all equipment's like SMD, PCB, arduino, relay module etc.
- Check the connection all the equipments which includes programming also.
- Recheck all components and check that connections are proper or not.
- Then make the first attempt for this system run.
- We know that we will fail several times but we will succeed at the end inshaallah.
- Uncertain data loss can be prevented. Computer systems which we use usually in office work do not have batteries.
- We get power supply at constant rate without any interruption.
- When main supply is not their we firstly connected to solar and then connecting our load to generator, through which we did not not have breakage of power even less then a minute.
- Huge power backup in the industries.
In this project, we hits on renewable energy sources to reduce the industrial cost and increase the industrial production. We can use this system in domestic use to get a constant power supply.
Mainly we do priority base switching. We set the priority of switching as follows.
- Solar
- Main supply
- Batteries
- Generator
