PLANT SIGNAL PROCESSOR WITH ESA TECHNOLOGY

摘要

A plant signal processor with ESA(Electricity Signature Analysis) technology is provided to perform measurement in a remote MCC(Motor Control Center) panel by determining a glitch part only through voltage and current without attaching any device to a motor or a load machine. A plant signal processor with ESA technology performs process control, system analysis, and equipment diagnosis through ESA signal analysis by receiving only AC voltage and current. The plant signal processor performs the steps of: obtaining and inducing three-phase voltage and current for the process control, system analysis, and equipment diagnosis through ESA; determining a glitch line by automatically calculating a revolution speed without a speed meter; automatically modeling a threshold; determining abnormality based on the modeled threshold and estimating an operation period according to an ROC(Rate Of Change) of deterioration; and diagnosing the abnormality and deterioration of a load machine by inducing torque.
