Voltage Control
There are a number of ways that voltage control is undertaken on the National Grid 400, 275, 132 kV system. This can be done by:
- Over/under excitation of generators
- Switching in/out of shunt reactors
- Switching out of overhead line and underground cable circuits
- Tap staggering of both supergrid and grid transformers
- Under/over excitation of synchronous compensators
- Declutching open cycle gas-turbines into the synchronous compensation mode
- Static variable compensators
- Manually switched capacitor banks
- Synchronous compensation of generators
- OLTC of generator step up transformer

Famous quotes containing the word control:
“There has been something crude and heartless and unfeeling in our haste to succeed and be great. Our thought has been “Let every man look out for himself, let every generation look out for itself,” while we reared giant machinery which made it impossible that any but those who stood at the levers of control should have any chance to look out for themselves.”
—Woodrow Wilson (1856–1924)
