DIAGNOZA DEFECTELOR PRIN ANALIZA DE SEMNALFOLOSIND MODELUL REDRESORULUI

摘要

In this paper are show methods to detect and analyse faults. For diagnose we used the methods basedrnon signals, on analytical models and based on knowledge. By critical analysis of diagnosernapproaching problem we can split up in three categories of knowledge's: factual knowledge, deductivernknowledge, strategy knowledge. To show up the consequences of the faults which may occur duringrnrunning of the three-phases rectifier were issued the two simulation cases: interrupting of onernthyristor and respectively short circuit a thyristor.
