Machine Condition Monitoring and Fault Diagnosis Using Spectral Analysis Techniques
There is need to continuously monitor the conditions of complex, expensive and process-critical machinery in order to detect its incipient breakdown as well as to ensure its high performance and operating safety. Depending on the application, several techniques are available for monitoring the condition of a machine. Vibration monitoring of rotating machinery is considered in this paper so as d...
متن کاملInduction Machine On-line Condition Monitoring and Fault Diagnosis – a Survey
Induction machines play a pivotal role in industry and there is a strong demand for their reliable and safe operation. They are generally reliable but eventually do wear out. Faults and failures of induction machines can lead to excessive downtimes and generate large losses in terms of maintenance and lost revenues, and this motivates the examination of on-line condition monitoring. On-line con...
متن کاملAdvanced Algorithms for Wind Turbine Condition Monitoring and Fault Diagnosis
The work undertaken in this research focuses on advanced condition monitoring and fault detection methods for wind turbines (WTs). Fourier Transform (FFT) and Short Time Fourier transform (STFT) algorithms are proposed to effectively extract fault signatures in generator current signals (GCS) for WT fault diagnosis. With this aim, a WT model has been implemented in the MATLAB/Simulink environme...
متن کاملWind Turbine Condition Monitoring and Fault Diagnosis using Wavelet Transforms
Some large wind turbines use a synchronous generator directly-coupled to the turbine. This paper considers condition monitoring and diagnosis of mechanical and electrical faults in such a variable speed machine. The application of wavelet transforms is investigated because of the disadvantages of conventional spectral techniques in processing instantaneous turbine signals. In this paper a new c...
متن کاملCondition Monitoring of Fault Diagnosis under Lubrication Condition in Ball Bearing using Infrared Thermography
In this paper, the novel approach for the rotating machine as diagnosis method in detecting the faults during its operation was proposed based upon the infrared thermograph technique. As experimental works, by performing the test of operation at several lubrication conditions for the ball bearing applied in the rotating machine which there has been used broadly, diagnosis evaluation and fault a...
