Volkov V. Improving the management of power active filter for industrial distribution networks

The thesis addressed an important scientific task consists in improving the automatic control of power active filter (SAF) in three-phase industrial distribution networks (XPS) study of the use of SAF to reduce network power losses and energy parameters that take into account the efficiency of compensation for non-active power generated by industrial loads. The mathematical and simulation (computer) model of electro-complex, which includes: RES, SAF, and various three-phase industrial loads (linear and nonlinear, active and active-reactive, balanced or unbalanced, including - automated electric AC and DC). Improved predictive control relay for the circuit in parallel SAF is characterized by at high speed and precision control network phase currents (SFT) reduced number of applications of sensors and a simplification of a prediction of the functional as well - an effective neutral current compensation network and minimizing switching frequency of power switches AFB with steady-state conditions. Carried out researches on the simulation model and the experimental sample SAF determine the energy parameters describing the efficiency of compensation for non-active capacity and reducing network power losses when using SAF with the proposed automatic control. The obtained analytical expressions allow to quantify the reduction in network power losses in the three-wire and four-RES by implementation of the balancing of SFT by SAF.
