Abstract: Prior battery-powered electric locomotives have used multiple diesel engines to charge the batteries and have not been commercially accepted. The present invention provides a yard switcher which combines battery storage with a gas microturbine generator to provide an effective fuel-efficient and environmentally friendly locomotive.

Abstract: A control system for individually controlling power from a single voltage source to a plurality of motors is described. A chopper circuit, in conjunction with the control system, generates drive-pulses, which operates the IGBT switching devices to sequentially provide pulses to each motor.

Abstract: The present invention is directed to a locomotive comprising energy storage units such as batteries, a prime energy source (1001), such as a diesel engine, and an energy conversion device (1002), such as a generator. The locomotive comprises one or more of the following features: a separate chopp er circuit (1010) for each traction motor (1008); energy storage units (1003) that can be switched from parallel to series electrical connections, a fluid - activated anti-lock brake system (1009), a controller (1015) operable to control separately and independently each axle(1006)/traction motor (1008), and a controller (1051) operable to control automatically a speed of the locomotive. The present invention includes an integrated system for monitoring, controlling and optimizing an electrically powered locomotive using a combination of sensors and software to provide feedback that optimiz es power train efficiency and individual drive axle (1006) performance for a locomotive that utilizes one of several possible electrical energy storage systems to provide the tractive power. The net result is a locomotive that h as an integrated system of control over all aspects of the locomotive power tra in including control over individual drive axles (1006), especially during acceleration, braking and non-synchronous wheel slip.

Abstract: 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.

Abstract: The present invention is directed to a control strategy for operating a plurality of prime power sources during propulsion, idling and braking and is applicable to large systems such as trucks, ships, cranes and locomotives utilizing diesel engines, gas turbine engines, other types of internal combustion engines, fuel cells or combinations of these that require substantial power and low emissions utilizing multiple power plant combinations. The present invention is directed at a general control strategy for a multi-engine systems where the power systems need not be of the same type or power rating and may even use different fuels. The invention is based on a common DC bus electrical architecture so that prime power sources need not be synchronized.
