Abstract

Some experiences with Probabilistic Transient Stability (PTS) evaluation of a real, medium-sized transmission system are described in this paper. A conditional probability theorem is utilized to simulate the probabilistic feature of transient stability. Emphasis is placed on alleviating the computational burden which has long been recognized as a major obstacle in PTS evaluation. An integration algorithm and network solution techniques are carefully elaborated for transient stability analyse. The modelling of nonsymmetrical fault is approximated using a compensation method and network transformation. Automatic contingency selection and knowledge-based rules are developed to further eliminate unnecessary stability analysis scenarios. As a result, PTS evaluation of a real, medium-sized transmission system can be completed using an affordable amount of computation time. Applications of the proposed method are illustrated.
