Optimization of the structure of filter-compensating devices in networks with powerful non-linear power consumers based on fuzzy logic

<span lang="EN-US">The article presents a solution to the problem of optimizing structure filter-compensating devices (FCD) when installed in high-voltage mine networks with powerful nonlinear electrical receivers. The urgency choosing rational FCD. design and installation location FCD is presented. main technical means compensation higher harmonics currents voltages receivers are considered. Analysis different types passive filters (PF) their frequency properties showed that choice specific PF refers multi-criteria optimization problem. methods variant construction based on use fuzzy sets proposed justified. To this end, calculation parameters characteristics equivalent systems "filter-external network" type for four possible combinations performed. optimal two resonant tuned 11<sup>th</sup> 13<sup>th</sup> harmonics, second-order broadband compensate starting from 23<sup>rd</sup> above. analysis simulation results effective harmonic voltages.</span>
