Fault induced delayed voltage recovery (FIDVR) is known to be caused by stalled air-conditioner compressor single phase induction motors (SPIMs). The traditional strategies to mitigate this phenomenon include tripping off the motors using thermal protection devices and installing voltage support devices to prevent voltage sag on the load side. This paper presents investigations and outcomes of several mitigation methods implemented on the distribution system using a recently developed point-on-wave transient air-conditioner compressor motor model. The effects of the dynamic voltage regulator (DVR) on preventing voltage sag are studied. A classical single phase variable speed H-bridge converter is implemented to explore its capability and fast response in mitigating FIDVR problem induced by a short-duration transient fault. An enhanced H-bridge converter is proposed to mitigate the impact of the long-duration fault contingency.
