The object of research - energy processes in electrical devices and systems with non-linear elements, processes, compensation inactive components of the current. The aim is to improve the methods for compensating the inactive components in a non-sinusoidal current and voltage unbalance analysis using energoprotsesiv active filter and the power control techniques in the frequency domain and the time domain. Research methods are based on the use of classical electrical theory, the theory of Fourier series; algorithm discrete convolution; small parameter method; trigonometric ratios, differential and integral calculus theory; approximation methods; methods of structural modeling; Mathematical modeling of a personal computer and experimental studies. Theoretical results: further developed methods of calculating the passive filters by using small-parameter method with the implementation of it in the frequency domain using the discrete convolution algorithm, the method of forming the frequency components of electrical quantities and presentation nonlinear parameter as resistance or conductance in the frequency domain, which, unlike by known methods, allows the calculation of the filter parameters on the nonlinear characteristics of the load and the predetermined refractive index sinusoidal voltage curve; first frequency-domain received balance equations constituting the instantaneous power of nonlinear electric circuit with semiconductor converters, and other nonlinear elements providing balance convergence by integrating the components of the instantaneous power on the nonlinear element, even if it is presented as a perfect element lossless that, unlike known It makes the sign of the harmonic components of the active power generated by the frequency components of voltage and current, to determine the direction of flow of a particular harmonic energy; for the first time in the frequency domain, the analytical expressions for the active and reactive power, harmonics and the rms values of the variables constituting the instantaneous power, compensation currents as a function of the higher harmonics and unbalance ratio of currents, which, in contrast to the known, allows to analyze modes of compensation systems in analytical form for improvement objectives and informed choice of their parameters; It was developed a method of compensation inactive components of load currents by determining the energy flow direction of the harmonic components and separation of harmonic voltage induced harmonious distortion of the mains voltage, which, in contrast to the classical, ensures correct operation of the compensation system, allows you to get the best energy performance, reduce the value of reactive power , voltage drop and distortion factor sinusoidal current and voltage curves in a harmonious distortion and unbalance voltage network.
