    摘要: Provided is a method for determining a filter change schedule for a gas turbine. The method includes determining differential pressure variation across filters and a time elapsed since a last filter change, where the differential pressure variation and the time elapsed are each associated with at least one filter disposed in the gas turbine. The method also includes estimating a future power loss and/or a future fuel consumption caused by the differential pressure variation. Moreover, the method can include determining the filter change schedule based on a cost of the filter change, the time elapsed, a cost of the future power loss, and optionally a cost of the future fuel consumption, a cost of emission variation, and a cost of production loss.
