1. A turbine to operate at part-load, comprising:

  • a compressor to intake a fluid;

    a combustion chamber to heat the fluid from the compressor;

    a turbine section to rotate a shaft with the heated fluid from the combustion chamber;

    a bypass circuit to generate a bypass flow by removing a portion of the fluid from the compressor and transmitting the portion of the fluid to the turbine section; and

    a controller to determine whether a part-load operation is selected, and to open the bypass circuit when the part-load operation is selected,wherein when the controller determines that the part-load operation is selected, the controller determines a normal part-load fluid intake to the compressor, increases the part-load fluid intake to the compressor by a predetermined first percentage above the normal part-load fluid intake, and controls the bypass circuit to remove the portion of the fluid from the compressor such that a percentage of the portion of the fluid removed from the compressor relative to the increased part-load fluid intake is less than or equal to the predetermined first percentage.
