A New Approach of Failure Warning and Monitoring Control System of Auxiliary Power Unit

This paper presents the study of a defect warning and control system. The developed system has the following functions: (a) detect possible defects in advance by controlling gas turbine compressors (GTC), (b) warn the user, and (c) ensure necessary intervention to prevent the defect from happening or growing is made.

The defect warning and control system is a product with a predicting maintenance approach. It measures the vibration, oil pressure, exhaust exit heat and engine speed parameters via sensors during the performance of the gas turbine compressors. It also monitors the action and warns the user in case of danger. If the evaluated parameters reach critical values which may cause a defect, the system detects this in advance and prevents unexpected defects. The application of this system has verified and demonstrated that its designed functions have been achieved successfully.
