Development of BCU classifiers for on-line dynamic contingencyscreening of electric power systems

摘要

A sequence of BCU classifiers for online dynamic contingencynscreening is developed and their theoretical basis is provided. Thendesign objective of the BCU classifiers is to ensure that unstablen(single-swing or multiswing) contingencies be completely captured andnthat the number of contingencies needed for further analysis bensignificantly reduced. An architecture for online dynamic securitynassessments consisting of the BCU classifiers and an online transientnstability (time-domain) simulation program is presented. Theneffectiveness of the developed BCU classifiers and proposed architecturenis evaluated with very promising results using 7120 contingencies on an50-generator, 145-bus power system and a 202-generator, 1293-bus realnpower system data
