Abstract
A method for determining efficiency of an installed steam turbine includes estimating, at a first plurality of times, a first mean value and a first variance of at least one performance variable of the steam turbine utilizing a set of station sensors. The method further includes estimating, at a second plurality of times including times encompassing at least some of the first plurality of times, a second mean value and a second variance of the at least one performance variable utilizing a different set of sensors, wherein the different set of sensors includes precision sensors. A mapping function is determined between the first mean values and the second mean values using the first mean values, the first variances, the second mean values, and the second variances.
