SYSTEM AND METHOD FOR MONITORING AN ELECTRICAL PATTERN AND PATTERN TRENDS IN ELECTRICALLY DRIVEN SYSTEMS

摘要

A system obtains respective measurements of relevant electrical parameters of a motor during operational stages including a start-up stage, a transition stage, a steady-state stage, idle stage, or a shutdown stage of the motor driven system driven by the motor. Based on the respective measurements, the monitoring system then determines respective electrical patterns corresponding to the operational stages. Next, the monitoring system compares the respective electrical patterns corresponding to the operational stages with respective baseline electrical patterns modeled for the operational stages to yield a comparison. Then, the monitoring system determines a status of the motor driven system based on a comparison between baseline and observed operating parameters. Trend pattern monitoring is used to eliminate storing massive volumes of trend data by capturing and characterizing the important moments when data values change in a significant manner.
