The steam input in to a turbogenerator connected to infinite bus is increased. Which of the events will take place?
- A. The generator will feed more leading KVAR to bus bar and power angle will not change
- B. The generator will feed more real power to bus bar and power angle will increase
- C. The generator will feed more power to bus bar and power angle will decrease
- D. The generator will feed more lagging KVAR to bus bar and power angle will not change
Answer: B. The generator will feed more real power to bus bar and power angle will increase
Explanation: Increasing steam input supplies more mechanical power (Pm), which increases the active electrical power output (Pe = (EV/X) sin δ) and increases the power/torque angle δ.
