Transformer failure due to circuit breaker induced switching transients applicable to the cement industry

Switching transients associated with circuit breakers have been observed for many years. Recently this phenomenon has been attributed to a significant number of transformer failures involving primary circuit breaker switching. These transformer failures had common contributing factors such as 1) primary vacuum or SF-6 breaker. 2) short cable or bus …

A Coordinated Design of PSSs and UPFC-based Stabilizer Using Genetic Algorithm

Using a criterion based on the damping ratio. an optimization algorithm was successfully applied to establish the optimal coordination between PSSs and UPFC-based stabilizer using Genetic Algorithm (GA). A multi-objective function was utilized to formulate the problem. whose solution aims to maximize the damping ratios of the electromechanical modes using …
