Phase Compensation for Gas Turbine Transient Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Performance analysis of gas turbine engines using steady state data is often inaccurate due to the rarity of truly steady state conditions, leading to less than optimal component design and inaccurate power capability assessments.
Innovation Solution
A method and system for phase compensating transient performance data by applying a transfer function to selected parameters, generating phase compensated data representative of a steady state relationship, using sensors and a processor to collect and process data from a gas turbine engine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If steady state performance data are used for performance analysis, then measurement precision is improved, but availability of data deteriorates because truly steady state conditions are rare in gas turbine engine operation
Solution Approach 1:
The patent transforms transient performance data into steady-state equivalent data by applying phase compensation techniques. This changes the temporal parameter of the data from transient to steady-state characteristics, allowing accurate performance analysis without requiring actual steady-state operating conditions. The transfer function compensates for phase shifts between different engine parameters, effectively converting transient data into forms that represent steady-state relationships.
2Adaptability or versatility
If non-steady state performance data are used, then data availability is improved, but measurement precision deteriorates due to phase shifts between parameters
Solution Approach 1:
The patent introduces a transfer function as an intermediary element that processes transient performance data. This transfer function acts as a mediator that compensates for phase shifts between different engine parameters, allowing non-steady state data to be accurately analyzed. The intermediary processing step transforms the raw transient data into phase-compensated data that reflects true steady-state relationships.
3Adaptability or versatility
If transient performance data are used without compensation, then data availability is improved, but reliability deteriorates due to inaccurate performance analysis
Solution Approach 1:
The patent applies phase compensation as a preliminary action before performing performance analysis. By pre-processing the transient data with appropriate transfer functions to compensate for phase shifts, the system ensures that subsequent performance analysis operates on corrected data. This preliminary compensation step guarantees reliable results while maintaining the ability to use transient data.

AI summary
A system and method of phase compensating transient performance data are provided. Transient performance data are collected for a plurality of parameters, and two of the parameters are selected. A transfer function is applied to the transient performance data for at least one of the selected parameters to thereby generate phase compensated performance data that is representative of a steady state relationship between the selected parameters.
