EVALUATION OF ELECTROMECHANICAL COMPLEX PARAMETERS BY ENERGY METHOD

Energy conversion processes are complicated by the presence of nonlinear processes elements and therefore worsens the quality of the transformed energy, electromechanical equipment wears out faster, losses increase have been shown. Therefore, for the effective use and management of energy processes relevant is the determination of estimates of energy processes in electrical circuits by means of parameter identification of nonlinearities significantly affect the energy conversion processes in the system. The proposed identification method is based on the instantaneous power concept. It is known that even with sinusoidal supply voltage and the presence of nonlinear elements the current in circuit is non-sinusoidal. Using instantaneous power apparatus allows us to get quantitative assessment of energy processes components at each harmonic and form a system with a sufficient number of equations for determining the unknown parameters of both linear and nonlinear energy systems.
