Decomposition of instantaneous power at constant and alternating orthogonal components can be defined as a measure of instantaneous power signals with different quality and physical characteristics and to create an acceptable system of quality indicators energy processes. Energy balance equation for each component of the instantaneous power is basis of the general characteristics of energy processes. Investigated the universal approximation of the original components of the apparatus of power mode using the trigonometric series. A method for the analysis of instantaneous power energy processes can be used in DC and AC currents in the static and transient modes with periodic and aperiodic signals for different environments. This allows us to obtain indicators of the energy regime in different environments, to ensure the adequacy of the results in the chain of energy conversion of complex electromechanical systems. First proposed energy approach to the assessment of control electromechanical systems using the instantaneous power. It is established that the energy controllability characterizes the quality of energy transformation processes in the system, reflects a manifestation of the nonlinear properties of the object. The measure of the quality of energy processes in the system is the effective power. The mathematical apparatus for determining the power loss for all of the power channel of the electromechanical power conversion industry. Proved that decomposition of the instantaneous power signal into orthogonal components reflect the actual energy state of electromechanical systems. It is shown that the formation of the balance equations for individual components of the instantaneous power is the basis for evaluating the energy of control of electromechanical systems. For the first time developed a method for the determination of electromagnetic parameters of induction motors based on the balance equations for the components of instantaneous power. Improved accuracy is achieved by forming a system of equations separately for identification constant, canonical and noncanonical components. Was further developed an approach to the determination of electromagnetic parameters of induction motors with acquired defects or damage. Choosing an appropriate equivalent circuit is based on the analysis of currents, voltages, instantaneous power and harmonic content. Determination of the parameters is done by solving the system of balance equations for the components of the identity of the instantaneous power. For the first time developed a method for diagnosis of defects and evaluation of the technical condition of induction motors with an analysis of the frequency spectrum and the integral characteristics of the consumption of blood pressure three-phase power, which is formalized in the form of logical rules for the determination of defects and damage.
