The combined frequency regulation of machines in area of capacity 1500 MW and operating at a normal frequency of 60 kHz is 0.1 puonits own base capacity. The regulation in Hz/ MW will be
-
- 0.1/1500
- 60/1500
- 6/1500
- 60/150
Correct Option: C
Area capacity = 1500 MW,
Nominal frequency = 60 Hz
Regulation = 0.1 pU = 10%.
This implies that when the load of 1500 MW is thrown off, then frequency rise
| = 6 Hz. | |
| 100 |
∴ Regulation = 6/1500 Hz/MW
