Abstract

Presents an engineering model of adaptive system of automatic stabilization of the power factor Cos φ = 1 as the condition of resonance at the frequency of power supply with parallel compensation of reactive power of electric drive of centrifuges battery of capacitors. The resonance in the power circuit corresponds to an extremum (minimum) of total current was taken as the goal of the algorithm automatic search. The operation of the adaptive control system in conjunction with a structural dynamic model of the object of optimization is presented modeling in terms of a Simulink (MATLAB). It is shown that in the process of automatic stabilization Cos φ = 1 excluded “overcompensation” in the local electric power network, including when disconnect blocs of the centrifuges. The adaptive control system is insensitive to additive errors of the sensor current I, can be realized general technical means and applied in general power networks.
