Abstract
Various control options are applied for selecting the number of operating power sources for a multi-power source vehicle having a number of prime power sources and, optionally including energy storage systems. This system and method are applicable to large vehicles such as locomotives, mining trucks, tugboats and large cranes. Selectable operating modes are provided for different locomotive speed ranges and work loads. The system and method are based on a common DC bus electrical architecture so that prime power sources need not be synchronized. Multiple-engine locomotives are included in which the engine systems may be electrically connected in parallel or in series or in combinations of parallel and series to a DC bus.
