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:
“I am the center of the world, but the control panel seems to be somewhere else.”
