Abstract
Class of identification problems continuously expanded mainly due to the increasing needs because of growth of features and class of solved technical and technological problems. The Problem of Identification this is the definition of the parameters a wide variety of electrical electromechanical systems. With regard to an electromechanical device that is a definition of electromechanical and electromagnetic parameters of electrical machines. Every year appears more than two hundred works devoted the mentioned scientific and technical task. The range of methods of the parameters identification of electrical equipment is extremely wide, from the simplest, based on elementary ideas about physical processes and equivalent circuits to complex, based on complex mathematical models of devices and systems. The analysis shows that the greatest interest of researchers cause different versions of frequency methods, particularly those where the notions of the processes supported by models of energy processes mainly in the frequency domain. Such studies are devoted to sufficiently large list of the results of studies carried out at the Kremenchuk Mykhailo Ostrohradskyi National University. The peculiarity of this work is that with sufficient wide range of use of frequency representations in solving specific problems (different frequency power supply of the motor windings, poly-harmonic voltage, pseudo polyharmonics supply, the use of pseudo sources of AC voltage, etc.) are using an original promising energy method, which is based on the use of energy balance equations components of the instantaneous power consumption of power supply and elements of the equivalent circuit of the electric machine, which takes into account any physical phenomena. Energy balance method applies to equivalent circuits of machines of alternating and direct current of any complexity. The importance and the prospect the method under consideration that it applies not only for the identification of electric circuits, but tools and machines with other energy conversion principles with linear and nonlinear characteristics.
