ABSTRACT:
A control method and apparatus for a gas turbine generator is disclosed having multiple modes of operation dependent on generator output components including real power generated, reactive power generated, and power factor. The apparatus provides for selecting a high priority output component, a low priority output component, and a variable output component. Depending on the priority selected, stator temperature is controlled with either a var limiter controller or a MW limiter controller. Rotor temperature is controlled by limiting excitation current substantially independently of priority selection. Setpoint selection may be variable and includes desired MW, MVAR's, and Power factor. This invention allows control of the generator to produce the maximum MVAR's the generator is capable of producing while at the same time utilizing the remainder of the gas turbine output capability for MW generation.
