A method for automatic creation of contingency definitions utilizing standard IEC 61968/70

This paper discusses a method of study contingency definition creation that utilizes a Common Information Model (CIM)-based balanced 3-phase bulk electric transmission model, minimal CIM schema extensions, and post-processing algorithms that employs a combination of explicit and implicit modeling methodologies to generate multi-element definitions for single and multiple breaker-to-breaker fault paths. Utilizing assumptions implicit in the base bulk electric model connectivity data reduces the labor necessary to maintain an accurate list of normal study contingency definitions in a temporal modeling environment, while using explicit modeling methods and additional post-processing logic under certain special circumstances provides for generation of study contingency definitions, associated remedial action schemes, special protection schemes, or other unique circumstances.
