Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Modeling thermodynamic processes in systems with powerful electric machines O.V. KRYUKOV Methods for the mathematical description of thermodynamic processes in the insulation of AC motors of the megawatt class are presented. The most useful when choosing a monitoring model for synchronous motors is a functional diagnostic model, in which the input effects of elementary checks are determined in advance by the operating algorithm of the object, and only the compositions of the monitored parameters of the diagnostic object are to be chosen. The results of an analysis of the dynamics of thermodynamic processes in stator windings of machines are obtained. Keywords: description methods, thermodynamic processes, drive electric motors, gas-pumping units. DOI: 10.25791/pribor.09.2018.186 Contacts: E-mail: o.v.kryukov@mail.ru Pp. 09-15.
