Knowledge
When do you need a DG synchronization panel?
A synchronization panel lets two or more generators, or generators and the grid, run in parallel and share load. It is the right choice when one DG is not enough or cannot be allowed to fail.
You need one when
- The plant load is larger than one DG set and several sets must share it.
- You want redundancy (N+1), so one set can be serviced while the others carry the load.
- Load varies widely and you want sets to start and stop automatically to save fuel.
- You need no-break changeover between grid and DG (requires DISCOM approval and grid-protection relays).
What is inside
| Part | Purpose |
|---|---|
| Motorised ACB per DG | Connects each set to the common bus |
| Synchronising & load-sharing controller | Matches voltage, frequency and phase, then shares kW and kVAr |
| Check-synchronising relay (25) | Blocks closing if the sets are out of phase |
| Protections | Reverse power (32), over/under voltage and frequency, over-current, earth fault |
| Load management | Auto start/stop by load, priority tripping of non-essential feeders |
