Abstract :
Three dynamic braking strategies for transient stabilisation of a power system are investigated. These involve resistor, resistor-reactor and resistor-capacitor switching, respectively. The switching strategies are obtained from an optimum feedback control law. The proposed controls are tested on a four-machine power system. It is observed that although all the optimal strategies are able to contain the first swing instability, the resistor-capacitor switching is the best for electromechanical as well as electrical transients control
