Kraftmaschinen-Startsystem und Verfahren

摘要

A method is provided of controlling the start-up and ignition of a prime mover such as a gas turbine engine in which the prime mover is coupled to a starter motor which provides motive power to the prime mover to accelerate the prime mover up to self-sustaining speed. The method comprises the steps of: (a) during a first phase prior to ignition of the prime mover, causing the starter motor to provide motive power to the prime mover so as to accelerate the prime mover at a first predetermined rate; (b) during a second phase subsequent to the first phase, causing the starter motor to provide motive power to the prime mover so as to accelerate the prime mover at a second predetermined rate which is less than the first predetermined rate; and (c) during the second phase, providing fuel to the prime mover to facilitate ignition of the prime mover.
