To meet the changing demands of bulk cargo loading operations in the Port of Long Beach, material handling processes can be improved by replacing existing across-the-line starters for induction motors with adjustable speed drives. In this thesis, the technical requirements, both well-known and new, of replacing an existing medium-voltage across-the-line starter with a state-of-the-art adjustable speed drive will be reviewed. The different topologies for solid-state power converters used in adjustable speed drives, the effect of cable length, and mechanical load consideration will be presented. A comparison between starting an induction motor using across-the-line starting versus starting with an adjustable speed drive will be analyzed using Matrix Laboratory, a multi-paradigm numerical computing environment and fourth-generation programming language. Recommendations will be made to resolve practical issues and provide a reliable, high-performance, engineering solution.
