Verified Answer
Two generating units rated 300 MW and 400 MW have governor speed regul...
Assume No – load speed regulations are equal
From similar triangles method
Given that P1 + P2 = 600MW
150x = 600
x = 4
∴The load supplied by largest machine is P2 = 100 x 4 = 400MW

Given data:
- Two generating units rated 300 MW and 400 MW
- Governor speed regulation of 6% and 4% respectively
- Operating in parallel to share a load of 600 MW
To find:
- Load shared by the larger unit
Solution:
1. Determine the speed regulation constant (K) for each generator:
- K = 100 / (% speed regulation)
- For 300 MW unit: K = 100 / 6 = 16.67
- For 400 MW unit: K = 100 / 4 = 25
2. Determine the droop (Ds) for each generator:
- Ds = (K / 100) * (rated power / total load)
- For 300 MW unit: Ds = (16.67 / 100) * (300 / 600) = 0.0833
- For 400 MW unit: Ds = (25 / 100) * (400 / 600) = 0.1667
3. Calculate the actual load shared by each generator:
- For 300 MW unit: actual load = 300 + (0.0833 * (600 - 300)) = 341.65 MW
- For 400 MW unit: actual load = 400 + (0.1667 * (600 - 400)) = 405.01 MW
4. Therefore, the load shared by the larger unit (400 MW) is approximately 405 MW.
Answer: 405 MW
- Two generating units rated 300 MW and 400 MW
- Governor speed regulation of 6% and 4% respectively
- Operating in parallel to share a load of 600 MW
To find:
- Load shared by the larger unit
Solution:
1. Determine the speed regulation constant (K) for each generator:
- K = 100 / (% speed regulation)
- For 300 MW unit: K = 100 / 6 = 16.67
- For 400 MW unit: K = 100 / 4 = 25
2. Determine the droop (Ds) for each generator:
- Ds = (K / 100) * (rated power / total load)
- For 300 MW unit: Ds = (16.67 / 100) * (300 / 600) = 0.0833
- For 400 MW unit: Ds = (25 / 100) * (400 / 600) = 0.1667
3. Calculate the actual load shared by each generator:
- For 300 MW unit: actual load = 300 + (0.0833 * (600 - 300)) = 341.65 MW
- For 400 MW unit: actual load = 400 + (0.1667 * (600 - 400)) = 405.01 MW
4. Therefore, the load shared by the larger unit (400 MW) is approximately 405 MW.
Answer: 405 MW
