Large motors are ubiquitous in a steel plant. Many of these motors require direct on-line (DOL) starting without speed or torque control. DOL applications create dynamic transients during starting. Using an example of a 10,000-hp motor from a recently executed project, this paper presents the study of the standard power quality compliance requirements, evaluation of the dynamic transients for various system initial states and the effects of these transients on the system. The paper also presents the procedure used for evaluation. Examples of compensation solutions evaluated, and the final solution selected is presented along with the criteria used for selection.
