Patent number: 10267185Abstract: A system may include an exhaust conduit configured to route an exhaust gas from an engine to a heat recovery steam generator (HRSG). The system may also include a coolant supply coupled to the exhaust conduit. The coolant supply is configured to supply a coolant to the exhaust conduit. Additionally, the system may include a controller configured to control the coolant supply to control an exhaust temperature of the exhaust gas flowing through the exhaust conduit from the engine to the HRSG, or a steam temperature of steam generated by the HRSG, or a combination thereof. The controller may be configured to control the coolant supply differently in a full load condition relative to a part load condition of the system.Type: GrantFiled: July 30, 2015Date of Patent: April 23, 2019Assignee: General Electric CompanyInventors: Harold Lamar Jordan, Jr., Kevin Wood Wilkes, John Edward Sholes, Yamil Miguel Morales Valvieja, John D Memmer

Patent number: 7853392Abstract: Embodiments of the invention can provide systems and methods for initializing dynamic model states using a Kalman or similar type filter. In one embodiment, a system for controlling a gas turbine engine is provided. The system can include at least one sensor adapted to obtain dynamic-type information about a current state of the engine. The system can also include an engine model adapted to receive information from the sensor, and further adapted to reflect the current state of the engine. Furthermore, the system can include a model filter adapted to initialize the engine model with at least a portion of the dynamic-type information, wherein at least one value based at least in part on the filtered dynamic-type information is input to the engine model to determine an engine control action.Type: GrantFiled: January 26, 2007Date of Patent: December 14, 2010Assignee: General Electric CompanyInventors: Timothy Andrew Healey, Randy S. Rosson, Kevin Wood Wilkes
