SYSTEM AND METHOD FOR GAS TURBINE POWER AUGMENTATION
First Claim
1. A gas turbine power augmentation system comprising:
- a chiller, the chiller operable to chill a coolant flow using energy from a heat source;
a controller operably connected to the chiller and configured to regulate operation of the chiller in relation to at least one environmental condition, wherein regulating operation of the chiller comprises operating the chiller to chill the coolant flow when the environmental condition is at a first environmental condition level and not operating the chiller to chill the coolant flow when the environmental condition is at a second environmental condition level;
a heat exchanger in fluid communication with the chiller and configured to allow the coolant flow to pass through the heat exchanger; and
a gas turbine inlet air flow, wherein the air flow is directed through the heat exchanger before entering a gas turbine inlet, allowing the air flow to interact with the coolant flow, thereby cooling the air flow.

Abstract
A gas turbine power augmentation system and method are provided. The system includes a chiller, a controller, a heat exchanger, and a gas turbine inlet air flow. The chiller may be operable to chill a coolant flow using energy from a heat source. The controller may be operably connected to the chiller and configured to regulate operation of the chiller in relation to at least one environmental condition. The heat exchanger may be in fluid communication with the chiller and configured to allow the coolant flow to pass through the heat exchanger. The gas turbine inlet air flow may be directed through the heat exchanger before entering a gas turbine inlet, allowing the air flow to interact with the coolant flow, thereby cooling the air flow.

11. A gas turbine power augmentation system comprising:
-
an absorption chiller, the absorption chiller operable to chill a coolant flow using energy from a heat source; a direct-contact heat exchanger, the direct-contact heat exchanger in fluid communication with the absorption chiller and configured to allow the coolant flow to pass through the direct-contact heat exchanger; a controller operably connected to the absorption chiller, the controller configured to monitor the ambient relative humidity of air upstream of the direct-contact heat exchanger, to operate the absorption chiller to chill the coolant flow when the ambient relative humidity is at or above a fixed ambient relative humidity level, and to not operate the absorption chiller to chill the coolant flow when the ambient relative humidity is below the fixed ambient relative humidity level; and a gas turbine inlet air flow, wherein the air flow is directed through the heat exchanger before entering a gas turbine inlet, allowing the air flow to interact with the coolant flow, thereby cooling the air flow, wherein the air flow is cooled primarily through sensible cooling when the ambient relative humidity is at or above the fixed ambient relative humidity level and cooled primarily through latent cooling when the ambient relative humidity is below the fixed ambient relative humidity level. - View Dependent Claims (12, 13)

14. A method for augmenting gas turbine power comprising:
-
measuring at least one environmental condition; regulating operation of a chiller in relation to the at least one environmental condition, wherein operation of the chiller chills a coolant flow using energy from a heat source, and wherein regulating operation of the chiller comprises operating the chiller to chill the coolant flow when the environmental condition is at a first environmental condition level and not operating the chiller to chill the coolant flow when the environmental condition is at a second environmental condition level; and communicating the coolant flow through a heat exchanger, wherein the heat exchanger is configured to allow a gas turbine inlet air flow passing through the heat exchanger to interact with the coolant flow, thereby cooling the air flow before the air flow enters a gas turbine inlet. - View Dependent Claims (15, 16, 17, 18, 19, 20)
