For a turbo generator rated at 44.1 MVA with a power factor of 0.9, what is the expected output in megawatts?

To determine the expected output of a turbo generator in megawatts, we can use the formula that relates the apparent power (measured in MVA) to real power (measured in MW) while factoring in the power factor (a measure of how effectively the electrical power is being used).

The formula is:

[ \text{Real Power (MW)} = \text{Apparent Power (MVA)} \times \text{Power Factor} ]

In this situation, the turbo generator has a rating of 44.1 MVA and a power factor of 0.9. By applying the formula:

[ \text{Real Power (MW)} = 44.1 \text{ MVA} \times 0.9 ]

Calculating that:

[ \text{Real Power (MW)} = 44.1 \times 0.9 = 39.69 \text{ MW} ]

This means that under the given conditions, the expected output from the turbo generator is 39.69 MW, which corresponds to the correct answer.

This approach demonstrates how the power factor plays a critical role in converting apparent power into real power, providing a practical understanding of the generator's efficiency in
