Title of Test | Control of voltage with an on-load tap change controller |
Test Rationale | Verify that an on-load tap changer controller “OLTC” is able to regulate the voltage level of the distribution network to the required value as stipulated both by international standards and by the network operator |
Specific Test System (graphical) | Grid voltage levels may be defined in specific cases, but the MV range expected is 0-36Kv. |

Initial system state |
|
Evolution of system state and test signals | Voltage signals monitored from start of experiment. Disturbances on the network are stabilized by changing tap position to return grid voltage level to within permitted grid voltage limits.. |
Other parameters | n/a |
Temporal resolution | 1ms |
Source of uncertainty | Communication delays, power supply fluctuations |
Suspension criteria / Stopping criteria | Uncontrollable abnormal system conditions, communications failures |
