A method of controlling the renewable energy absorbed by a hybrid power train for driving a load, and in particular compressors for a liquefied natural gas (LNG) plant is disclosed. The method comprises an analysis of the health status of part and of the whole hybrid power plant that drive the load. A power plant is also disclosed, operated by the controlling method.

Method of controlling the renewable energy use in an LNG train

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.

Methods and systems for optimizing filter change interval

A method for predicting the residual useful life of an air filter arrangement is described. The method includes the following steps: providing a plurality of predetermined reference degradation curves; measuring a degradation parameter of the filter arrangement; and estimating the residual useful life of the filter arrangement by comparing the predetermined reference degradation curves and an actual degradation curve defined by measured values of the degradation parameter.

System and method for controlling a stuck nozzle system installed between first and second turbines connected in series to a compressor. The method includes determining whether the nozzle system is stuck; instructing the first turbine to increase a minimum speed reference when the nozzle system is stuck; verifying whether the nozzle system continues to be stuck; instructing the compressor to increase an inlet bleed heat (IBH) flow from a current value to a maximum value when the nozzle system is stuck; verifying whether the nozzle system continues to be stuck; and instructing the compressor to increase an inlet guide vanes (IGV) angle from a current value to a maximum value when the nozzle system is stuck.
