Question
A cylindrical rotor synchronous generator with constant real power output and constant terminal voltage is supplying current to a lagging power factor load. An ideal reactor is now connected in parallel with the load, as a result of which the total lagging reactive power requirement of the load is twice the previous value while the real power remains unchanged. The armature current is now __________ A (rounded off to 2 decimal places).
Correct answer
123 to 127
Solution
1.Initial State:
- Current
- Power factor lagging
- Real power
- Reactive power
- Real power remains constant at .
- Total reactive power .
- New armature current .
