Transmission Network Tools

This suite of tools aimed at transmission network operators and planners includes options for analysing the voltage stability and power transfer capabilities of the network. With this module, the Outage Planning module is also provided, offering the capability for modelling planned outages and associated system reconfigurations.

PV curves calculation

  • Voltage stability assessment by determination of critical point of voltage instability
  • Support contingency analysis, i.e. detection of “limiting contingency”

QV curves calculation

  • Voltage stability limit assessment by evaluating the bus voltage change w.r.t variation of injected reactive power
  • Evaluation of stable operating points for various system loading scenarios, including contingencies
  • Determination of reactive power compensation by superposition of capacitor characteristics in QV plots

Power Transfer Distribution Factors

  • Analysis of the impact of a power exchange between two regions
  • Various load and generation scaling options

Transfer Capacity Analysis

  • Determination of maximum power transfer capacity between two regions
  • Various load and generation scaling options for exporting and importing region
  • Thermal, voltage and contingency constraints options

Outage Planning

The Outage Planning module is part of the Transmission Network Tools. Details see in main chapter Outage Planning.
