I have two DG sets which are to be synchronized on to the same AC bus and needless to say, they must share load. I have gathered some parametric data which I felt would decide how well these can work as part of single bus. But I am not sure, and would like to know what the experts feel about these two DG sets getting synced easily.
DG-1
Engine Data:
- 1200KW
- 50Hz
- Power Factor (Cos Phi): 0.7
Generator Data:
- 3 Phase - 6 Wire
- X Wye Delta,
- X Series Parallel
- 600 Volts
- 1828 Amps
- 1714KVA
- Sub Transient X"D : 0.133 per unit 0.028 Ohms
- Transient X"D : 0.197 per unit 0.043 Ohms
Excitation Data:
- 31 Volts, 7.1 Amps
- Separately Excited
Frame: - 826 Frame - 1500 Rev/Min
DG-2
Engine Data:
- 1330KW - KW is specified at a higher PF here
- 50Hz
- Power Factor (Cos Phi): 0.8
Generator Data:
- 3 Phase - 6 Wire
- KH734E Wye
- P7 Series
- 600 Volts
- 1492 Amps - So Amps is much lesser than DG-1
- 1662.5KVA - So KVA is slightly less than DG-1
- Sub Transient X"D : 0.101 per unit 0.092 Ohms
- Transient X"D : 0.581 per unit 0.21 Ohms
Excitation Data:
- 45 Volts, 3.5 Amps - Excitation power is also much lesser than DG-1
- Separately Excited
Frame: - Steel Frame - 1500 Rev/Min
Any kind of help shall be highly appreciated.
Best Regards,
