Abstract:
A method of starting up a turbo including a gas turbine, a generator and an exciter, wherein the exciter has a exciter stator winding and a exciter rotor winding, comprising the steps of;supplying a three-phase current to the exciter stator winding, the three-phase current inducing a voltage in the exciter rotor winding as an asynchronous generator, generating a current in the exciter rotor winding by the induced voltage being rectified by a rectifier rotating with the exciter rotor winding and the current being supplied as direct current to a generator rotor winding of the generator, and passing a three-phase current through a generator stator winding of the generator which thereby acts as a converter-fed motor.
