Abstract
A method of controlling the part-load performance of a turbine includes generating a bypass flow in the turbine by removing a portion of a compressed fluid from a compressor of the turbine, determining an operating load of the turbine, transmitting the bypass flow to a turbine section of the turbine; and selectively heating the bypass flow according to the determined operating load of the turbine.
Claims19
A turbine, comprising:
- a compressor to intake a fluid and compress the fluid;
- a combustion section to combust a fuel to generate heated fluid by heating the fluid from the compressor;
- a turbine section to convert the heated fluid to work;
- and
- a bypass circuit to generate a bypass flow by taking in compressed fluid from the compressor, to selectively heat the bypass flow according to an operation mode of the turbine, and to output the bypass flow to the turbine section.

A power generation system, comprising:
- a turbine having a compressor to take in and compress a fluid, a combustion section to heat the fluid from the compressor, a turbine section to drive a shaft with the fluid heated by the combustion section, an exhaust section to eject the fluid from the turbine section, and a bypass circuit to generate a bypass flow by taking in a portion of the fluid compressed by the compressor and selectively directing the bypass flow to the turbine section and the exhaust section;
- and
- a turbine control unit to determine an operating mode of the turbine, and to control the bypass circuit to transmit the bypass flow to one of the turbine section and the exhaust section according to a determined operating mode.
