Contingency Analysis

Analyze & Visualize Thousands of Contingencies in Minutes
ETAP Contingency Analysis (CA) allows users to define component outage and failure scenarios. From the user-defined scenarios, system N-1 and N-2 contingencies are studied. ETAP contingency analysis employs a fast screening or ranking algorithm to select a ranked contingency list for detailed studies.
Contingency Analysis Report Summary

 

Contingency Analysis Capabilities

  • N-1 and N-2 contingency assessment and ranking
  • Fast screening method to scan outage list and identify higher risk contingencies for further evaluation
  • Multiple graphical outage lists
  • Ability to compare contingency load flow with base load flow via graphical interface
Contingency Analysis

Performance Indices

  • Bus voltage security
  • Reactive power flow change index
  • Branch overloading index
  • Real power flow change

Contingency Analyzer

  • Complete load flow
  • Interrupted generation power loss
  • Interrupted customer power loss
  • Interrupted number of customers
  • Interrupted power lost cost
Various performing indices are available and selectable for fast contingency screening and ranking. A full AC load flow is applied to perform detailed studies to give maximum accuracy in the analytical results. Based on user-defined voltage, branch limits, other system operating condition violation criteria, violation warning and alarm reports are generated. Limits and violations can be based on either component ratings or component base case operating values.
