Abstract

A typical power plant has a plurality of generators; at least one load; at least one bus interconnecting the generators and the at least one load. The plant is operated on an uncorrected droop configuration for speed control and voltage control. The plant further includes a monitoring module for monitoring at least one of a plurality of signals; a calculating module for calculating a fault based on a comparison of predefined values expected from normal droop operation with respect to monitored values obtained from the monitored signals; and a control module for providing an order to bring additional generating capacity on line, for tripping a generator if a fault has been identified with respect to a single generator or for tripping a tie breaker to provide bus to bus isolation if an identified fault cannot be isolated to a single generator.
