Embodiment Construction

[0016] The exemplary methods and systems described herein provide a control system capable of maintaining / maintaining operating parameters such as temperature within a turbine engine. The control system includes at least one sensor disposed within the turbine engine, wherein the sensor is configured to detect at least one first operating parameter within the turbine engine. A controller is connected to the sensor, and the controller is configured to receive at least one second operating parameter of the turbine engine. The controller is also configured to control fluid flow to the rotor assembly within the turbine engine such that the fluid is substantially evenly distributed within the rotor assembly and at least one of the first operating parameter and the second operating parameter is less than at least one threshold. By controlling fluid flow delivered to the rotor assembly, operating parameters within the turbine engine may be maintained below thresholds. For example, te...

Abstract

A control system (160) is provided. The control system includes at least one sensor positioned within a turbine engine (102), wherein the sensor is configured to detect at least one first operating parameter within the turbine engine. A controller is coupled to the sensor and the controller is configured to receive at least one second operating parameter of the turbine engine. The controller is also configured to control a flow of a fluid to a rotor assembly (132) within the turbine engine such that the fluid is distributed substantially uniformly within the rotor assembly and 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 present 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 turbine engines, such as gas turbine engines, that include rotor assemblies. 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 paddles coupled to each rotor disk. Each blade or paddle includes an airfoil radially outward from the platform towards the casing. [0003] During operation of at least some known gas turbine engines, a compressor compresses air that is mixed with fuel and delivered to a combustor. The mixture is then ignited to generate hot combustion gases, which are then sent to a turbine. Turbines extract energy from the combustion gases to power compresso...
