Abstract

The application of analytical hierarchy process (AHP) to determine the impact of special protection schemes (SPS) failures in a power system is described in this paper. The application of AHP reduces time and effort in locating the most and least vulnerable SPS as it integrates an expert's service experience in the field and probability tools. Its major advantage is that can be used by persons who have little field experience. The 179 bus Western States Coordinating Council (WSCC) system was chosen as the power system to illustrate this technique. Each generator site is assumed to be equipped with a SPS that is capable of tripping generation. The objective of the project is to study the impact of SPS misoperations due to hidden failures in the SPS at the most critical bus locations. Such failures would cause the most severe problems. This bus or 'site' could then be a candidate for installation of redundant supervisory control measures in an attempt to avoid the worst-case scenario.
