Benefits of technology

The patent text describes different embodiments of a gas turbine system, which includes a compressor with inlet guide vanes and variable stator vanes. The system also includes actuators that can adjust the pitch of these vanes. The actuators are driven by electric motors, and a controller is used to control the motors. The actuator system includes a frusto-conical washer and a spring to ensure proper operation. The technical effects of these embodiments include improved efficiency, control, and reliability of gas turbine systems.

Problems solved by technology

Unfortunately, the flow and pressure of the fluids into the compressor or turbine may be unstable or unsuitable for particular operating modes of the gas turbine system.

Embodiment Construction

[0014]One or more specific embodiments of the present invention will be described below. In an effort to provide a concise description of these embodiments, all features of an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.

[0015]When introducing elements of various embodiments of the present invention, the articles “a,”“an,”“the,” and “said” are intended to mean that ther...

Abstract

A gas turbine system includes a compressor. The compressor has a plurality of inlet guide vanes disposed at an inlet of the compressor. Furthermore, the compressor may have at least one unison ring coupled to a plurality of variable stator vanes disposed between the inlet and an outlet of the compressor. The gas turbine system includes a first actuator that may adjust a first pitch of the plurality of inlet guide vanes and a second actuator that may adjust a second pitch of the plurality of variable stator vanes. A first electric motor may drive the first actuator, while a second electric motor may drive the second actuator.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of U.S. patent application Ser. No. 13 / 721,000, entitled “SYSTEM FOR TURBOMACHINE VANE CONTROL” and filed on Dec. 19, 2012, which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The subject matter disclosed herein relates to gas turbines, and more specifically, to systems for controlling operation of the gas turbine.[0003]Gas turbine systems generally include a compressor, a combustor, and a turbine. The compressor compresses air from an air intake, and subsequently directs the compressed air to the combustor. In the combustor, the compressed air received from the compressor is mixed with a fuel and is combusted to create combustion gases. The combustion gases are directed into the turbine. In the turbine, the combustion gases pass across turbine blades of the turbine, thereby driving the turbine blades, and a shaft to which the turbine blades are attached, into rotati...
