Parameters:
| Monitored Bus | Bus at which the voltage is monitored |
| volt_high | High cut-in voltage (pu) |
| volt_low | Low cut-in voltage (pu) |
| td_high | High cut-in time delay (sec) |
| td_low | Low cut-in time delay (sec) |
| Extra Object 1 | Line 1 |
| Extra Object 2 | Line 2 |
| Extra Object 3 | Line 3 |
| Extra Object 4 | Line 4 |
| Extra Object 5 | Line 5 |
| Extra Object 6 | Line 6 |
| Extra Object 7 | Line 7 |
| Extra Object 8 | Interface 1 |
The following pseudo code describes how the inputs are used to determine series capacitor switching:
SeriesCap = Series capacitor to which this model is assigned
LineSectionsAreOpen = Any line section open for Extra Object 1 to 7
CapBlocked = ((Interface1 MW Flow < -50) OR (Interface1 MW Flow > 0)) AND LineSectionsAreOpen
If ((not CapBlocked) and (SeriesCap.Status = Bypassed)) AND ((Monitored Bus Voltage < volt_low for td_low) OR (Monitored Bus Voltage < volt_high for td_high))
Then Begin
SeriesCap.Status = Not Bypassed
End
