Abstract

This study investigates the physical mechanism of ferroresonance and its control. Based on this mechanism, a flexible control method for ferroresonance is proposed, and its control mechanism is discussed. High-frequency controllable switches are used in the control module proposed in this study, and several parameters of the control module can be adjusted according to ferroresonance types identified by the comprehensive identification system and saturation degrees of the ferroresonance. The control module is then switched into the secondary circuit of the potential transformer, and ferroresonance can be controlled. Simulation and experimentation show that ferroresonance of various types and saturation degrees can be restrained.
