Variable-structure braking-resistor control in a multimachine power system

This paper describes a variable structure control for dynamic braking resistors in a multimachine power system to improve the transient performance and thus increase transfer capability. The simulation of a system with 54 buses and 17 generators shows that the new control is very effective for this multimodal system. The control provides very good damping to the appearing oscillation modes and also increases effectively the transient stability limit.<
