Abstract
In a gas turbine system having first power converter converting power system N AC voltage to DC voltage, second power converter converting the DC voltage into AC voltage, generator connected to second power converter's AC output and rotated by turbine and turbine controller outputting a revolution speed command value omg* according to a fuel flow rate of the turbine, a detector for detects a revolution speed omg of the generator, another detector detects Vdc of the first converter, a speed regulator generats a DC voltage command value according to a difference between omg and omg*, a switchover unit selects either a preset DC voltage command value Vref or the DC voltage command value according to the revolution speed omg and a voltage regulator and a controller control first power converter conversion output according to a control signal for making Vdc coincide with Vdc*.
