The present invention is directed to applying various control options for selecting the number of operating power sources for a multi-power source vehicle comprised of a number of prime power sources and, optionally including energy storage systems. The invention is applicable to large vehicles such as locomotives, mining trucks, tugboats and large cranes. The present invention is directed specifically at providing selectable operating modes for different locomotive speed ranges and work loads. The invention is based on a common DC bus electrical architecture so that prime power sources need not be synchronized. The invention includes multiple- engine locomotives 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.

La présente invention concerne l'application de diverses options de commande pour sélectionner le nombre de sources de puissance fonctionnelles pour un véhicule à multiples sources de puissance constitué d'un nombre de sources de puissance principales et, comprenant facultativement des systèmes de stockage d'énergie. L'invention est applicable à de grands véhicules tels que des locomotives, des camions d'exploitation minière, des remorqueurs et de grandes grues. La présente invention concerne en particulier la fourniture de modes de fonctionnement sélectionnables pour différentes gammes de vitesses et de charges de travail de locomotive. L'invention est fondée sur une architecture électrique de bus DC commun, de telle sorte que des sources de puissance principales n'ont pas besoin d'être synchronisées. L'invention comprend des locomotives à plusieurs moteurs dans lesquelles les systèmes de moteur peuvent être connectés électriquement en parallèle ou en série ou en combinaisons de connexions en parallèle et en série à un bus DC.
