SYSTEMS AND METHODS FOR IMPROVED ACCURACY

摘要

Systems and methods for determining turbine engine system stability encompass measuring or otherwise determining values of performance parameters, storing a data set of such values in memory, generating a stability indicator, and displaying the stability indicator on an operator interface. The stability indicator is generated by a processor operating in data communication with the computer memory, utilizing customized software algorithms to remove high frequency components, apply an adaptive filter to adjust selected parameters according to a target value of a selected target parameter, and apply a stochastic filters to estimate true values of the selected parameters, based on the remaining variation.

1. A method for determining turbine engine system stability, the method comprising:
determining values of performance parameters for a turbine engine system, the performance parameters including independent parameters and dependent parameters forming a data set generated over a selected data acquisition period; storing the data set in computer memory; with a computer processor in communication with the computer memory:
removing high frequency components from the determined values of the performance parameters;applying an adaptive filter to adjust the determined values of the dependent parameters according to a target value of a selected independent parameter, wherein the adaptive filter is corrected based on prior determined values of the performance parameters;applying a stochastic filter to reduce noise in each of the determined values;estimating true values of the dependent parameters, based on a remaining variation in the determined values; andgenerating a stability indicator for the turbine engine system, based on variation in the estimated true values of the dependent parameters; and displaying the stability indicator on an operator interface in communication with the computer processor.
