Single-Phase Induction Motor Under Voltage Fluctuations

Abstract

Some of the most common power quality disturbances are voltage fluctuations. They are interconnected with the presence of voltage subharmonics and interharmonics. Voltage fluctuations, subharmonics and interharmonics exert a negative effect on various elements of a power system, including cage induction motors. This work is devoted to the impact of voltage fluctuations on the current of a one-phase induction motor. The results of empirical investigations are presented for sinusoidal amplitude modulations of various frequencies and are compared with the effects of voltage subharmonics occurring as a single power quality disturbance.
