Model-Plant Performance Matching from the Limited Number of Measured Quantities for Gas Power Generator
The matching technique of model-plant performance data can be used to solve several problems,such as fault diagnosis,the model calibration and deterioration estimation etc.In present paper,model-plant performance matching from the limited number of measured quantities is proposed.A gas power generator is modeling in simulating environments to constitute a benchmark case.Assumed the health factors are constant at adjacent zone of operating points,several discrete points are selected to compensate the number of measured quantities.Depending on the interrelated equations between measured residuals and health factors,the nonlinear Least Square is used to optimize the object value of components health factors.Several sets of simulated deterioration and fault data are naturalized as the testing case,the better matching of model-plant is obtained from the simulating results.
