• This paper proposes an operating mode of a BR bank, which was originally installed in generation system to promote the stability as well as improve the transient response, to suppress turbine blade vibrations arising from power system faults. Because most of cumulative blade damages are produced in the beginning cycles, this approach is mainly to restrict the initial amplitude of vibrations to reduce the vibration damage to turbine-generator blades. Also, only turning on the BR bank about a cycle time is adequate to effectively restrict the peak system-frequency E/M disturbing torques. Since the system-frequency responses always play an essential role on blade vibration behaviors arising from power system disturbances, vibrations can be significantly suppressed accordingly. The BR bank is activated at the instant of power system disturbances, it will dissipate only small amount of energy.
