Abstract
Taiwan Power Company (TPC) has implemented an event-based special protection system (SPS) against extreme contingencies. The decision making mechanism of the event-based SPS is based on look-up tables. A huge number of contingency analyses are required for constructing and updating the look-up tables. In this paper, automation techniques are developed to increase the analysis efficiency for speeding up preparing a look-up table. Contingency selection algorithms including both the depth-first algorithm and breadth-first algorithm are used to search for contingency cases automatically. A preprocess interface is designed to provide a friendly user-machine interface between the power system raw data and simulation software. And a computer program is developed to integrate the search algorithm and preprocess interface for fulfilling the automation of contingency analysis for SPS. The techniques realized with programs demonstrate a great time-saving advantage compared to traditional man-made work. The automation of contingency analysis for SPS does not only speed up the simulation process but also improve the efficiency, which is well demonstrated in the paper.
