A static synchronous compensator for displacement power factor correction under distorted mains voltage conditions/Statiniu sinchroniniu galios korekcijos kompensatoriu naudojimas esant nestabiliai maitinimo itampai

A STATCOM system is presented in this paper applied for compensation of displacement power factor under distorted mains voltage conditions. The developed STATCOM control system consists of two regulating loops--DC link voltage control loop with antiwindup PI controller and the current control loop with a feed-forward PI controller. The simulation results indicate that the developed control system performs well, ensuring displacement power factor compensation with good transient and steady state performance even under significantly distorted grid voltage conditions.

Aprasoma statinrq sinchroniniu kompensatoriu (STATCOM) sistema, skirta galios korekcijai, kai maitinimo itampa yra nestabili. Sukurta STATCOM valdymo sistema sudaryta is dvieju reguliavimo grandinin. Sumodeliavus siuloma sistema nustatyta, kad tokia valdymo sistema veikia gerai ir uztikrina poslinkio galios koeficiento kompensacija ir esant dideliems maitinimo jtampos svyravimams.
