Impact Technologies-Power and Industrial Performance Monitoring

Performance Monitoring

Gas Turbines

For gas turbines Impact provides performance monitoring as part of a comprehensive health assessment approach. This approach includes: Signal Validation, Performance anomaly detection using SignalPro™, Vibration Monitoring, and Troubleshooting. In addition, Impact Technologies has developed technology for gas turbine combustion pattern factor control.

Steam Turbines

For steam turbines, Impact developed the FAST (Flow Analysis for Steam Turbines) software for the Electric Power Research Institute. This software allows a turbine operator to make both technical and economic assessments of proposed modifications.

Active Combustion Pattern Factor Control

Impact Technologies developed and performed application studies for an innovative active combustion pattern factor controller (APFC) for gas turbines. The APFC system determines combustion flame temperatures, validates the values, and integrates an assessment of signal and combustion hardware health to determine how to trim the fuel flow to individual fuel nozzles.

Impact TEchnologies Active Combustion Pattern Factor Control

Key aspects of the system include:

Determination of each flame’s bulk temperature.
Assessment of the reliability of both the flame temperature data and physical combustion hardware health through analysis of features calculated from the high frequency output of the sensor.
Validation of the flame temperature signal using a data-driven approach.
Fusion of sensor ‘health indices’ into the APFC to alter the trim control signal based on the health of each sensor and fuel nozzle/combustor.
Fault-tolerant peak/valley detection and control switching module that selects individual fuel valves to target to reduce the pattern factor, while simultaneously balancing the overall fuel flow so as not to affect the engine output.

PerformanceCheck™ Performance Diagnostic Module

Sensor data can be passed to automated fault detection and diagnostic routines for analyzing engine performance related faults. These routines are based on extensive empirical knowledge of how healthy engines operate under normal test cell conditions (based on engine test cell data and engine models)Any deviation from this "normal" pattern of expected parameters will be detected and further analyzed. Faults resulting from sensor failure modes are promptly isolated by PerformanceCheck™, while more complex faults are identified by advanced fault pattern classification and statistical analysis schemes.

Independent performance diagnostic techniques that examine particular aspects of performance degradation are fused together to obtain the most robust performance diagnosis possible. These independent techniques include a Statistical Fault Classifier and a Kalman filter Single Fault Isolator (Kalman SFI).
