Title:
電気機械システムの状態を監視する方法及び装置
Document Type and Number:
Japanese Patent JP5932022
Kind Code:
B2
Abstract:
The present invention is concerned with a method, an apparatus and a computer program for monitoring the condition of electromechanical systems in which electrical rotating machinery is used and in which at least one electrical signal is measured during an operation of the electromechanical system. The inventive method comprising the steps of measuring current and/or voltage signals of an electromechanical system, measuring an angular position of a rotating shaft of interest of the electromechanical systems or estimating the value of discrete angular position of a rotating shaft of interest of the electromechanical system, synchronizing the current and/or voltage signals to the scaled angular displacement of the rotating shaft, dividing the synchronous electrical signals into intervals corresponding to each completed rotation of the rotating shaft, averaging a number of intervals of synchronous electrical signals to obtain an average synchronous electrical signal, extracting characteristic data of the magnitude from the values of the average synchronous electrical signal, comparing the extracted characteristic data of the magnitude with a threshold which is given as a limit and indicating an alarm to the user when the limit is exceed.
