Inlet air heating system for a gas turbine system

An inlet air heating system for a gas turbine system, comprising:

• an inlet heat exchanger configured to be positioned upstream of a compressor of the gas turbine system;
• a heating loop fluidly coupled to the inlet heat exchanger, wherein the heating loop is configured to provide heating fluid to the inlet heat exchanger, and the inlet heat exchanger is configured to facilitate transfer of heat from the heating fluid to an airflow into the compressor;
• a first heat transfer assembly configured to receive cooling tower fluid from a fluid pathway extending between a steam condenser and a cooling tower, wherein the heat transfer assembly is configured to facilitate transfer of heat from the cooling tower fluid to the heating fluid;
• a second heat transfer assembly configured to receive heated fluid from a steam turbine system, wherein the second heat transfer assembly is configured to facilitate transfer of heat from the heated fluid to the heating fluid;
• a first valve configured to control a first flow rate of the cooling tower fluid through the first heat transfer assembly;
• a second valve configured to control a second flow rate of the heated fluid through the second heat transfer assembly;
• a third valve configured to control a third flow rate of the heating fluid through the heating loop;
• and
• a controller comprising a memory and a processor, wherein the controller is communicatively coupled to the first valve, to the second valve, and to the third valve, and the controller is configured to control the first valve, the second valve, and the third valve.
