A synchronous generator connected to an infinite bus is overexcited. Consider the only reactive power, from the point of view of the system, the machine acts as
- A. a capacitor
- B. an inductor
- C. a resistor
- D. none of these
Answer: A. a capacitor
Explanation: An overexcited generator delivers lagging reactive power, i.e. it behaves like a capacitor to the system.
