Title: METHODS AND SYSTEMS FOR OPTIMIZING FILTER CHANGE INTERVAL
Abstract:
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 (304), 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 (306). 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 (308).
