摘要： Embodiments of the disclosure can relate to quantification of gas turbine inlet filter blockage. In one embodiment, a method can include receiving data associated with an inlet flow conditioning system associated with a turbine in a power plant. The method may further include determining an inlet flow associated with the turbine, based at least in part on operational data from the turbine. The method may further include determining an effective area of the inlet flow conditioning system, based at least in part on the inlet flow associated with the turbine. The method can further include determining a fouling rate of the inlet flow conditioning system, based at least in part on a difference between the effective area of the inlet flow conditioning system and a corresponding effective area of the inlet flow conditioning system determined at a prior operation. The method may further include identifying a corrective recommendation for the inlet flow conditioning system, based at least in part on the fouling rate and a performance target of the turbine.

摘要： A system includes a power generation system and a controller. The controller includes processors that receive a first set of inputs. The processors also generate a first set of modeled outputs system based on a model of the power generation system and the first set of inputs. The processors further receive a first set of measured outputs corresponding to the first set of modeled outputs. The processors determine a first correction factor based on the first set of modeled outputs and the first set of measured outputs. The first correction factor includes differences between the first set of modeled outputs and the first set of measured outputs. The processors also generate a second set of modeled outputs based on the model, a second set of inputs, and the first correction factor. The processors further control an operation of the power generation system based on the second set of modeled outputs.

摘要： A method includes instructing a purge valve of a gas turbine system to open, thereby purging a fuel circuit by filling the fuel circuit with purge gas, wherein the fuel circuit initially contains fuel. The method also includes generating a model of the gas turbine system that simulates a modeled output based on a model input corresponding to a measured input. The method further includes receiving a measured output of the gas turbine system. The method also includes adjusting the model input such that the modeled output more closely matches the measured output when the measured output is not approximately equal to the modeled output. The method further includes instructing the purge valve to open during a subsequent purge operation and a gas control valve to open more fully or at least partially close during the subsequent purge operation based at least in part on adjusting the model input

摘要： A system may include a memory storing a turbomachinery degradation model configured to model degradation of a turbine system over time. Further, the system may include a controller communicatively coupled to the memory, which derives a turbomachinery wash timing based on at least one input signal from the turbine system and the turbomachinery degradation model. The turbomachinery degradation model may derive a desired wash point by estimating a modeled power of the turbine system, a modeled heat rate of the turbine system, or both. Furthermore, the controller may use the desired wash point to determine a time for washing components of the turbine system.

摘要： A system includes a controller coupled to an inlet bleed heat system of a compressor. The controller is configured to detect an icing condition of an inlet portion of the compressor by determining a current compressor efficiency value of the compressor, a current compressor flow value of the compressor, or any combination thereof, comparing the current compressor efficiency value to a compressor efficiency model of the compressor, the current compressor flow value to a compressor flow model of the compressor, or any combination thereof, and providing an icing indication to the inlet bleed heat system if a first difference between the current compressor efficiency value and the compressor efficiency model is greater than a first threshold, a second difference between the current compressor flow value and the compressor flow model is greater than a second threshold, or any combination thereof.

摘要： A system includes a power generation system and controllers that control operations of the power generation system. The controllers include processors that receive multiple values associated with operating parameters of the power generation system, and determine a degradation cost function that quantifies a degradation cost based on the values. The processors further receive an operation cost that includes a fixed financial cost of performing an operation on the power generation system, and determine an operation cost function that quantifies the operation cost. The processors further determine a total cost function of the power generation system based on the degradation cost function and the operation cost function, and determine times to perform the operation on the power generation system based on the total cost function. The processors further send an alert to perform the operation of the power generation system at the times.

摘要： A method includes instructing a gas control valve of a gas turbine system to open, thereby prefilling a fuel circuit of the gas turbine system with fuel, wherein the fuel circuit is initially filled with purge gas. The method also includes generating a model of the gas turbine system that simulates a modeled output of the gas turbine system based on a model input corresponding to a measured input to the gas turbine system. The method further includes receiving a measured output of the gas turbine system. The method also includes adjusting the model input such that the modeled output more closely matches the measured output when the measured output is not approximately equal to the modeled output. The method further includes instructing the gas control valve to open to prefill the fuel circuit during a subsequent prefill operation based at least in part on adjusting the model input.

摘要： A system includes a power generation system and a controller that controls the power generation system. The controller includes a processor that generates a model of the power generation system that estimates a value for a first parameter of the power generation system. The processor also receives a measured value of the first parameter. The processor further adjusts a correction factor of the model such that the estimated value of the first parameter output by the model is approximately equal to the measured value of the first parameter. The processor also generates a transfer function that represents the correction factor as a function of a second parameter of the power generation system. The processor further displays the transfer function along with one or more previously generated transfer functions to quantify degradation of the power generation system.
