Operator interface for an electric power generation system
First Claim
1. A method, comprising:
- carrying a mobile electric power generation system with a vehicle, the system including a variable speed genset, an electrochemical battery, an inverter coupled to the genset and the battery through a DC bus, and an operator interface with two or more operator input devices;
selecting an automatic mode of system operation with one of the operator input devices;
in response to the selecting of the automatic mode, controlling system operation in an automatic mode that includes activating operation of both the genset and the inverter;
switching from the automatic mode to manual control of the system with the interface; and
during the manual control of the system, changing operating state of the genset and the inverter with one or more other of the operator input devices.

Abstract
A mobile electric power generation system includes a variable speed generator, an engine to drive the generator, a DC bus coupled to the generator, an inverter coupled between the DC bus and an electrical power bus in the vehicle, an electrical energy storage device coupled to the DC bus, an operator interface including a display and several operator input devices, and operating logic executed by a processor. One operator input device is used to initiate an automatic mode of operation of the system. The operating logic is structured to activate both the generator and the inverter during the automatic mode. Another operator input device is selected to initiate a manual mode of operation. The operating logic is responsive to one input to change activation of the generator and to another to change activation of the inverter.
