This format was first created as a means to exchange data for defining contingencies and Remedial Action Schemes (RAS) among entities throughout the Western Electricity Coordinating Council (WECC). Starting in version 18 this format is an enhancement to the data section of the traditional auxiliary file format found in Simulator, and it can be loaded into Simulator anywhere that an auxiliary file can be loaded.
A file can be saved in this format from the Save button found on the bottom of the Contingency Analysis dialog. The Save as type entry needs to be set to WECC Contingency and RAS File (*.aux).
