Given data:
Alternator G1 rating = 300 MW
Alternator G2 rating = 600 MW
Droop characteristics of G1 = 3
Droop characteristics of G2 = 4
Total load = 800 MW
Calculating the load sharing:
The load sharing between the two alternators can be calculated using the formula:
Load sharing = (Rating of alternator / Total rating) * Total load
Load sharing of G1 = (300 / (300 + 600)) * 800 = 200 MW
Load sharing of G2 = (600 / (300 + 600)) * 800 = 400 MW
Calculating the frequency drop:
The frequency drop can be calculated using the formula:
Frequency drop = (Load sharing / Rating) * Droop characteristics
Frequency drop of G1 = (200 / 300) * 3 = 2 Hz
Frequency drop of G2 = (400 / 600) * 4 = 2.67 Hz
Calculating the system frequency:
The system frequency can be calculated by subtracting the frequency drop from the no-load frequency.
System frequency = No-load frequency - Frequency drop
Given no-load frequency = 50 Hz
System frequency = 50 - 2 - 2.67 = 45.33 Hz
Conclusion:
The system frequency at a total load of 800 MW will be approximately 45.33 Hz, which is not provided as an option in the given choices. Therefore, none of the options provided is correct.
