Overall approach to the reliability evaluation of composite generation and transmission systems

摘要: The reliability evaluation of combined generation and transmission systems is presently receiving considerable attention as utilities are finding it increasingly necessary to quantitatively evaluate individual busbar overall system indices. This paper presents an overview the problem describes a technique developed at University Saskatchewan which evaluates indices by considering all possible simultaneous (or overlapping) independent outage combinations generating units, lines transformers. calculated after alleviating line overloads, generator MVAr overloads etc. arising because situations. Common-mode or common-cause outages two on same right-of-way, tower, also included in analysis. A digital computer program for evaluating composite described. can, present, consider first second order outages. effectiveness illustrated application 30-busbar model practical power system.
