چکیده
Abstract. a novel method of fault diagnosis for power electronics rectifier based on PCA-SVM is presented in this paper. First, the features of the fault was extracted by principal component analysis (PCA), an SVM algorithm was introduced to train the SVM for diagnosis. Experimental results presented in this paper show that the diagnostic method has very good diagnostic ability and efficient; and have a good outreach capacity under small-sample. It has the very good practical value and applicable prospect in the solution to fault question for power electronics rectifier.

متن کاملDiagnosis of Different Types of Air-Gap Eccentricity Fault in Switched Reluctance Motors Using Transient Finite Element Method
This paper presents a method for diagnosis of eccentricity fault in a switched-reluctance motor (SRM) during offline and standstill modes. In this method, the fault signature is differential induced voltage (DIV) achieved by injecting diagnostic pulses to the motor windings. It will be demonstrated by means of results that there is a correlation between differential induced voltage and eccentri...

متن کاملRecognition and Location of Power Transformer Turn to Turn Fault by Analysis of Winding Imposed Forces
Turn to turn fault is one of the major internal failures in the power transformers that if it is not quickly detected, can be extended and led to a complete transformer breakdown. So, the diagnosis and location of the turn to turn fault of the power transformer, as one of the most important equipment in the power system, is the main objective of this paper. For this purpose, a detailed model of...
متن کاملA Novel Flux-Based Protection Scheme for Power Transformers
Internal Turn-Turn faults (TTF) are the most common failures in power transformers, which could seriously reduce their life expectancy. Although common protection schemes such as current-baseddifferential protection are able to detect some of the internal faults, some other minor ones (such as TTFs andshort circuit near the neutral point) cannot be detected by such schemes. Likewise, these rela...
