Abstract
A trolley capable mining truck includes a pantograph supported on a machine frame for electrically connecting the truck with an overhead trolley line. A power system includes an onboard electrical power source providing electrical power to electric drive propulsion motors along a first electrical path in a first configuration of the power system. The pantograph provides electrical power from the overhead trolley line to the electric drive propulsion motors along a second electrical path, which includes a transient damping reactor, in a second configuration of the power system. The power system also includes a third configuration in which, during a braking mode of the trolley capable mining truck, the electric drive propulsion motors provide regenerative electrical power to the overhead trolley line through the pantograph along a third electrical path including a regenerative power converter, wherein the regenerative power converter includes the transient damping reactor.
