Patent number: 11286864Abstract: Disclosed are systems and methods for active inlet turbine control. The systems and methods may include receiving a plurality of signals, determining a temperature gradient across an inlet of a gas turbine engine, and transmitting an activation signal to a modulating valve. Each of the plurality of signals may correspond to a temperature measured by one of a plurality of sensors located proximate the inlet of the gas turbine engine. The temperature gradient across the inlet of the gas turbine engine may be determined based on the plurality of signals. The activation signal may be operative to open or close the modulating valve based on the temperature gradient.Type: GrantFiled: July 8, 2020Date of Patent: March 29, 2022Assignee: Mitsubishi Power Americas, Inc.Inventor: Lisa Batsch-Smith

Patent number: 11070064Abstract: A method (110) of controlling an imbalance response in a power plant comprising first and second gas turbine engines and a steam turbine driven by steam generated by exhaust from the first and second gas turbine engines can comprise operating the first gas turbine engine at a first power output (116A), operating the second gas turbine engine at a second power output (116B), monitoring load demand from a power grid operating at a steady state condition (114), detecting a load imbalance on the power grid (120) that causes a deviation from the steady state condition, and adjusting the first power output and the second power output incongruently (128) during the imbalance response to change the first power output and the second power output to match the deviation from the steady state condition depending on contemporaneous efficiency states of the first and second gas turbine engines.Type: GrantFiled: December 8, 2017Date of Patent: July 20, 2021Assignees: Mitsubishi Power Americas, Inc., Mitsubishi Power, Ltd.Inventor: Lisa Batsch-Smith
