Design of Uninterrupted power supply under faulty condition
Uninterrupted 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.
An 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.
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.
| Item Name | Type | No. of Units | Per Unit Cost (in Rs) | Total (in Rs) |
|---|---|---|---|---|
| Aurduino | Equipment | 1 | 3000 | 3000 |
| Transfotmer | Equipment | 3 | 1200 | 3600 |
| Invertor (we made by him self) | Equipment | 1 | 4000 | 4000 |
| Solar panel (PV) | Equipment | 1 | 8500 | 8500 |
| Relay module (4 channel) | Equipment | 1 | 700 | 700 |
