Abstract
Control modes for operating multiple power sources include energy storage systems and applicable to large systems such as locomotives. Selectable operating modes are provided for different locomotive speed ranges and work loads. A common DC bus electrical architecture is used so that prime power sources need not be synchronized. Multiple-engine locomotives have the engine systems that may be electrically connected in parallel or in series or in combinations of parallel and series to a DC bus.
