Starting pipeline motors under severe power system constraints

The conventional methods of limited kVA starting are reviewed and compared to the application of an adjustable-speed drive sized for starting duty only. The use of this relatively new application is described with reference to an actual installation. The economics of the method are explored in order to provide some guidelines for future applications. A case study is also presented which is a conglomerate of the applications of conventional methods used over a number of years. Since the use of adjustable-speed drives for starting duty is relatively new for pipeline applications, the study, for clarity, deals with one specific case.<
