GAS TURBINE GENERATOR TORQUE DC TO DC CONVERTER CONTROL SYSTEM

摘要

A system includes a first controller configured to control a gas turbine to operate at a constant speed set point and a variable torque output to drive a generator. A DC to DC converter may operate as a load on a power source bus supplied by the generator. A second controller may limit a rate of change of the DC output power of the DC to DC converter during intermittent supply of a transient step change load subsequent to receipt of a transient load control signal. The transient load control signal is anticipatory of application of the transient step change load to the load bus. The rate of change is limited by the second controller to maintain the variable torque of the gas turbine below a predetermined threshold as a load ramp rate of the DC to DC converter changes on the power source bus.
