Patent ID: 7614239

Claim:
A method for optimized starting of an auxiliary group connectable to a main group of a turbine installation, the main group having at least one-first turbine and a generator connected for drive purposes to the first turbine, and the auxiliary group having at least one second turbine, the turbine installation including a first braking device configured to apply braking torque to the auxiliary group when the auxiliary group is decoupled from the main group, the method comprising: starting the main group and the auxiliary group decoupled from one another; applying a braking torque to the auxiliary group using the first braking device during the starting of the auxiliary group, the braking torque to the auxiliary group being controllable, wherein the first braking device is at least one of a fluid brake, electrical brake, and mechanical brake; and coupling the auxiliary group to the main group after the main group and the auxiliary group have been started.
