Abstract
The present invention provides a redundant prime mover system to drive a machine having an engine coupled to the machine, and a motor/generator coupled to the machine and an electrical network connection. The engine and the motor/generator have three or four operating modes. The first operating mode drives the machine with the engine. The second operating mode drives the machine with the motor/generator. The third operating mode drives the machine and the motor/generator with the engine such that the motor/generator generates electricity for delivery to the electrical network connection. Alternatively, the third operating mode drives the machine with both the engine and the motor/generator. This alternate operating mode can also be included as a fourth operating mode.
