Abstract: A method of estimating a remaining life of a valve is disclosed, comprising steps of collecting valve actuation force data; calculating an average value of the valve actuation force data in at least one of a plurality of actuation cycles; estimating a remaining life of the valve using a model based on the calculated average values of the valve actuation force data obtained from the at least some of the plurality of cycles and a valve actuation force limit. A valve controller (20, 21) of estimating a remaining life of a valve is also disclosed.

Abstract: A flutter control system for a turbine includes a processor. The processor is configured to detect blade flutter of a turbine. The blade flutter indicates that blades of the turbine are in a deflected position different from a nominal operating position. The processor is configured to control operational parameters of the turbine that reduce or eliminate the blade flutter to improve the reliability and efficiency of the turbine.
