Access

The Circuits Tab in the Main Window Display Panel.

Purpose

To display Dynamic Information related to all Circuits for a Current Data Set.

Data Types

Column Description
Name
Circuit Name (as provided by Transpower or user-named)
From/To Node
The nodes linked by the Circuit. The From and To designations are used for reference when calculating flow direction:
  • Flow FROM => TO is +ve
  • Flow TO => FROM is -ve
IsHVDC Indicator
Indicates the Circuit is included in the HVDC Modelling when checked
Resistance
Circuit resistance (in Ω)

Reactance

Circuit reactance (in Ω)
Fixed Losses
Fixed losses (in MW) associated with the Circuit
Capacity
Capacity of the Circuit (in MW) for the current period
Powerflow
Flow in Circuit (in MW) for the current period
P.S.
The price separation across the nodes connected by the Circuit after deducting Price differences due to losses. This is useful for identifying Circuits affected by Equation Constraints.
Losses
The Losses (in MW) associated with the line for the current period
Loading
Percentage of total capacity used in the Current Period expressed as a number between 0 and 1
SFT PF
The SFT protection factor - See How EMO models SFT constraints. This is valid for lines only
SFT PFQ
The SFT curvature - See How EMO models SFT constraints. This is valid for lines only
SFT Threshold
The SFT Threshold - See How EMO models SFT constraints. This is valid for lines only
SFT Tmax
The Thermnal limit of the circuit - See How EMO models SFT constraints. This is valid for lines only

NOTE: Double-clicking on any row will open a separate Circuit Information Window for the associated Circuit.
