First Claim
1. A power system comprising:
- a first controller configured to control a first generator;
a second controller configured to control a second generator, the second generator electrically coupled with the first generator; and
a plurality of rotational loads electrically coupled with the first generator and the second generator;
the first controller configured to excite the first generator to generate alternating current (AC) electric power at a time of commencement of rotation of the first generator;
the second controller configured to excite the second generator at the time of commencement of rotation of the first generator such that the second generator is energized to operate as a motor in response to receipt of the AC power generated by the first generator; and
the second generator and the plurality of rotational loads configured to commence rotation with the first generator at the time of commencement of rotation of the first generator due to receipt of the AC electric power.

Abstract
A power system includes a bus, a first controller and one or more second controllers. The first controller is configured to excite a first generator to generate electric power on the bus in response to initiation of rotation of the first generator. The one or more second controllers are configured to excite one or more respective second generators with a constant excitation in response to initiation of rotation of the first generator. The second generator(s) are electrically coupled with the bus and configured to operate as a motor to commence synchronous rotation with the first generator in response to electric power being present on the bus. The second controller(s) are further configured to initiate dynamic adjustment of the excitation of the second generator(s) to generate electric power on the bus with the second generator(s) in response to the first generator and the second generator(s) synchronously reaching a predetermined rotational speed.

15. A method comprising:
-
initiating rotation of a first generator with a prime mover during a startup mode; applying a dynamically variable excitation to the first generator during the startup mode to generate electric power in response to initiation of rotation of the first generator; generating electric power on a bus with the first generator during the startup mode in response to initiation of the rotation of the first generator and application of the dynamically variable excitation to the first generator; applying an excitation which is a constant to a second generator electrically coupled with the bus and supplying electric power generated by the first generator to the second generator during the startup mode to energize the second generator in response to initiation of rotation of the first generator; synchronously rotating the first generator and the second generator during the startup mode while the second generator is energized by the electric power generated by the first generator and a rotational speed of the first generator is ramped to a predetermined rotational speed; and initiating dynamic adjustment of the excitation applied to the second generator in response to the first generator and the second generator reaching the predetermined rotational speed and transitioning from the startup mode to an operational mode. - View Dependent Claims (16, 17, 18, 19, 20)
