 In the work, the approaches, circuit topology solutions and control algorithms to increase the efficiency of a hybrid compensator of inactive power based on a power active filter and an adjustable battery of capacitors are proposed: proposed methods of a choice of capacitances of stages of the capacitor bank; developed a mathematical model that includes processes occurring in the electrical network, electrical load consuming non-sinusoidal currents, and processes in a hybrid compensator; with the help of mathematical modeling, the theoretical substantiation of possibility of application of the offered approaches to control of the hybrid compensator is proved. The task of compensation of the reactive component of the mains current is realized, the possibility of reducing the harmonic distortion of the mains current is provided. Тhe effect of neutral grounding on the parameters of the zero sequence of the medium voltage electrical network is analyzed. Тhe results are presented of the study of modes of operation of crane wound rotor induction motors, simulated operation with damaged winding(s), performed a synthesis of the structure and developed an algorithm for early diagnosis of wound rotor induction motors. The object of research - methods and approaches to increase the energy efficiency of induction electric drive and means of compensation for nonactive power, in particular, parallel and hybrid active power filters. The purpose of the work is to develop new and improve existing technical means and control methods to increase the energy efficiency of nonactive power compensation means, to diagnose the condition of crane induction motors. Research methods – in the work, a mathematical apparatus for analysis and synthesis of automatic continuous- and discrete-time control systems is used; theory of linear and nonlinear electric circuits; direct and inverse Fourier transform; mathematical apparatus for digital signal processing.
