Systems and methods for turbine system operation in low ambient temperatures

A system comprising:

• a controller communicatively coupled to a compressor and configured to:
• sense an exhaust temperature of a gas turbine system, wherein the gas turbine system is fluidly coupled to the compressor;
• derive a setpoint based on the sensed exhaust temperature;
• and
• actuate a inlet bleed heat valve based on the derived setpoint and an ambient temperature, wherein the inlet bleed heat valve directs a compressor fluid from the compressor into an fluid intake system fluidly coupled to the compressor upstream of the compressor, wherein the fluid intake system is configured to intake a fluid.

A non-transitory, computer-readable medium comprising executable code comprising instructions configured to:

• receive an input corresponding to an exhaust temperature of a turbine system;
• retrieve a baseload control function for a compressor system coupled to the turbine system;
• retrieve data corresponding to a design limit of the compressor system;
• determine a difference between an operating level of the compressor system and the design limit of the compressor system;
• calculate an exhaust temperature bias based on the baseload control function and the exhaust temperature;
• actuate an inlet bleed heat valve based on the exhaust temperature bias and the difference between the operating level of the compressor system and the design limit of the compressor system, wherein the inlet bleed heat valve directs direct a compressor fluid from the compressor system into an fluid intake system fluidly coupled to the compressor system upstream of the compressor system, wherein the fluid intake system is configured to intake a fluid.
