A synchronous generator is disclosed having main power windings and auxiliary power windings, where the auxiliary power winding is coupled to a variable frequency drive system. The variable frequency drive causes the generator to function as a motor and turn a drive shaft to start a gas turbine. Switching circuits are used to connect and disconnect the auxiliary windings of the generator with the variable frequency power supply.
1. A method for starting a gas turbine using a polyphase electric power generator comprising the steps of: a. connecting a variable frequency power supply to auxiliary windings of the generator; b. applying current to the auxiliary windings of the generator to turn a drive shaft of the generator; c. rotating a gas turbine with the turning rotor of the generator to start the gas turbine, and d. once started, the gas turbine turns the generator to cause the generator to produce electric power from the main armature windings. 2. A method for startin...
