Transient motor reacceleration study in an integrated petrochemical facility

The reliability of the power supply can be significantly improved by modifying the electric motors' reacceleration scheme. It will mitigate the effect of lengthy and simultaneous acceleration by staggering the high inrush current demand. Transient simulations were performed at an integrated petrochemical facility to verify the effectiveness of the existing reacceleration scheme. The results indicated that the existing scheme will perform better with some changes, as discussed further.
