Note: all branches (whether transmission lines or transformers) appear on the Lines sub-tab. See
Lines above for setting up common branch quantities. Only branches containing transformers will
appear on the Transformers sub-tab.
Type - set the transformer type (Fixed, LTC, Mvar, or Phase)
Reg Val - regulated value for the transformer control
Tap Pos - tap position
Reg Err - deviation of the regulated value from the regulation Min/Max range
All fields specified above except for the Type field are used to determine which quantities should be
monitored and stored during the analysis. The Type field can be accessed here in order to change
the type of transformer. The type will not be monitored during the analysis.
Shunts
This allows the monitoring of switched shunt parameters.
Actual Q - actual reactive power output
Actual P - actual real power output
Nom Q - nominal reactive power output
Nom P - nominal real power output
Reg Err - deviation of the regulated value from the regulation Min/Max range. This can either be in
per unit voltage or Mvar depending on the type of regulation that the shunt is doing.
Reg Val - value of regulated quantity at the regulated bus. This can either be in per unit voltage or
Mvar depending on the type of regulation that the shunt is doing.
Interfaces
MW Flow - real power flow
Mvar Flow - reactive power flow
MVA Flow - total power flow
MW Loss - real power losses
Mvar Loss - reactive power losses
Interface PTDF - Power Transfer Distribution Factor on the interface due to a defined real power
transfer. This parameter only makes sense when doing the PV analysis. The PTDF is calculated for
the transfer from the selected source to sink. This is a meaningless quantity for the QV analysis and
should not be monitored.
Case
These options allow the tracking of case quantities to provide a better picture of what is going on in
the case as a whole without requiring the individual tracking of quantities that make up the case
total. These quantities are determined in the same manner as those found in the Case Totals section
of the Case Summary dialog.
Available quantities for tracking include:
Load MW/Mvar - total real or reactive power load for the entire case
