Embodiment Construction

[0050] The exemplary methods and systems described herein provide a control system that enables maintenance of operating parameters, such as temperature, within a turbine engine. The control system includes at least one sensor positioned within the turbine engine and configured to detect at least one first operating parameter therein. A controller is coupled to the sensor. The controller is configured to receive at least one second operating parameter of the turbine engine. Additionally, the controller is configured to control flow of fluid to the rotor assembly within the turbine engine such that at least one of the first operating parameter and the second operating parameter is less than at least one threshold. By controlling fluid flow directed to the rotor assembly, operating parameters within the turbine engine may be maintained below thresholds. For example, temperature levels may be at appropriate levels such that heat-related damage to components within the rotor ass...

Abstract

A control system is provided. The control system includes at least one sensor (204) that is positioned within a turbine engine and is configured to detect at least one first operating parameter therein. A controller (214) is coupled to the sensor. The controller (214) is configured to receive at least one second operating parameter of the turbine engine. Moreover, the controller (214) is configured to control a flow of a fluid to a rotor assembly within the turbine engine such that at least one of the first operating parameter and the second operating parameter is less than at least one threshold value.

Description

technical field [0001] The field of the invention relates generally to power generation systems, and more particularly, to control systems and methods for use in controlling the operation of power generation systems. Background technique [0002] At least some known power generation systems include a turbine engine, such as a gas turbine engine, having a rotor assembly. At least some known rotor assemblies include a rotor shaft, at least one rotor disk coupled to the rotor shaft, and a plurality of circumferentially spaced blades or buckets coupled to each rotor disk. Each blade or bucket includes an airfoil extending radially outward from the platform toward the casing. [0003] During operation of at least some known gas turbine engines, a compressor compresses air that is mixed with fuel and directed to a combustor. The mixture is then ignited, producing hot combustion gases that are then directed to the turbine. The turbine extracts energy from the combustion gases fo...
