Modeling and assessment of station originated outages for composite systems reliability evaluation

摘要

Consideration is given to the impact that terminal-station failure events have on the contingencies of connected lines and generators that should be included in the reliability evaluation of a composite system. Algorithms are described that simulate various failure modes of station components, deduce the resulting contingencies and their reliability indices, group together identical contingencies, and cumulate the resulting reliability indices. This is a novel approach for determining the effect of station failures on station-originated outages. The results can be used to assess the reliability of the stations themselves and as input data to a composite system reliability evaluation technique.
