Patent number: 9605559Abstract: A system may include a memory storing a turbomachinery degradation model configured to model degradation of a turbine system over time. Further, the system may include a controller communicatively coupled to the memory, which derives a turbomachinery wash timing based on at least one input signal from the turbine system and the turbomachinery degradation model. The turbomachinery degradation model may derive a desired wash point by estimating a modeled power of the turbine system, a modeled heat rate of the turbine system, or both. Furthermore, the controller may use the desired wash point to determine a time for washing components of the turbine system.Type: GrantFiled: February 2, 2015Date of Patent: March 28, 2017Assignee: General Electric CompanyInventors: Alan Meier Truesdale, David Spencer Ewens, Sidharth Abrol

Patent number: 8813472Abstract: A system includes a controller configured to control a semi-closed power cycle system. The controller is configured to receive at least one of a first signal indicative of an oxygen concentration within a first gas flow through a primary compressor, a second signal indicative of power output by the semi-closed power cycle system, a third signal indicative of a temperature of a second gas flow through a turbine, and a fourth signal indicative of a mass flow balance within the semi-closed power cycle system. The controller is also configured to adjust at least one of the first gas flow through the primary compressor, a fuel flow into a combustor, a fraction of the first gas flow extracted from the primary compressor, and an air flow through a feed compressor based on the at least one of the first signal, the second signal, the third signal, and the fourth signal.Type: GrantFiled: October 21, 2010Date of Patent: August 26, 2014Assignee: General Electric CompanyInventors: James Anthony West, Alan Meier Truesdale

Publication number: 20100287948Abstract: Control of gas turbine speed and acceleration during unloaded rotation may limit stresses on components and facilitate timely operational performance. Operation of a torque converter driving a gas turbine shaft from a starter motor provides control over acceleration and speed of the gas turbine shaft. Hydraulic coupling between the input and output of the torque converter is adjusted by draining and refilling the working fluid in a body of the torque converter to control acceleration and speed of the rotor shaft during a first speed range. Vane positioning within the torque converter may be alternated between discrete speed settings to control acceleration and speed of the rotor shaft during a second speed range. A turbine control system with an acceleration schedule may provide control signals for these functions.Type: ApplicationFiled: May 10, 2010Publication date: November 18, 2010Inventors: Sam David Draper, Douglas Edward Dean, Alan Meier Truesdale, Joseph Michael Harvey
