Zusammenfassung:Systems, methods, and apparatuses for storing energy in a mining machine. One embodiment provides a haulage vehicle including a bi-directional electrical bus, a power source coupled to the bi-directional electrical bus, a motor coupled to the bi-directional electrical bus and operating a drive mechanism included in the haulage vehicle, a kinetic energy storage system coupled to the bi-directional electrical bus, and a controller configured to communicate with the kinetic energy storage system and the power source. The kinetic energy storage system includes a flywheel and a switched reluctance motor. The controller is configured to operate the kinetic energy storage system as a primary power source for the bi-directional electrical bus and to operate the power source as a secondary power source for the bi-directional electrical bus when the kinetic energy storage system cannot satisfy an energy demand on the bi-directional electrical bus.
