TSAT-Contingency-Creator

Contingency Creator

The Contingency Creator is an add-on module for TSAT. It allows transmission planners and coordinators to automatically create TSAT contingencies using an easy-to-use wizard. Currently, it is able to create contingencies compliant to the NERC TPL-001-4 standard.

The Contingency Creator is able to use substation node-breaker data to create TPL compliant contingencies. Since the tool uses the same exemplary engine to read powerflow and node-breaker data as DSAToolsTM, large system data can be handled easily.

Approach

Traditional powerflow files and/or node-breaker or CIM information is input to the Contingency Creator. Users make use the tool’s intuitive, systematic wizard like interface to create TPL- 001-4 standard compliant contingencies. The Contingency Creator takes full advantage of the comprehensive modelling and computation options available in DSAToolsTM, developed by Powertech Labs Inc.

An array of customizable parameters for creating contingencies exist that include:

  • TSAT simulation parameters
  • Subsystem parameters
  • Fault clearance time
  • Contingency category and event specification
  • Transmission circuit reclosing option
  • Extreme event scenarios for specific category of contingencies e.g. stuck breaker
  • Contingency output option (list sequence, contingency title format)
Product Features
  • Complaint with NERC TPL- 001-4 standard
  • Ability to create and customize contingencies based on substation node-breaker or CIM data
  • Intuitive, functional wizard like user interface
  • Define, select, and customize subsystem to apply contingencies
  • Save study configuration to share with others or later use
Applications

The following are some of the salient features of the tool that allows for an enhanced user experience:

  • Define subsystem that is either substation based on the balancing authority/planning entity’s boundaries
  • Save study configuration of the tool for sharing amongst teammates or later use
  • Multiple options to customize contingencies e.g. custom tags to name contingencies

Examples

For a typical transmission level substation shown on the right, the Contingency Creator will automatically make a total of 52 contingencies as per the TPL standard. A breakdown of the number of contingencies per category is shown in table below. The contingency file created by the tool can be used in TSAT for studies.

Category Contingency Description No. of Contingencies
P1 Single Contingency System 5
P2 Single Contingency - Substation 6
P3 Multiple Contingencies - Generator 0
P4 Stuck Breaker 12
P5 Relay Failure 12
P6 Multiple Contingencies - Other 16
P7 Multiple Contingencies - Common Structure 1

Specifications and Requirements
  • Powerflow in PFB, RAW, or GE EPC format
  • Needs node-breaker data in PSAT XML format if creating contingencies for substations and for breaker-level events
  • TSAT must be installed to use the contingencies produced by the tool
  • Run on MS Windows 7/10/Server 2012 R2/Server 2016
