Abstract

This paper presents the investigation of harmonic currents of a power system associated with a static Var compensator for grid-connected induction generators under condition of low wind speed. The static Var compensator uses fixed capacitor and thyristor controlled reactor. The investigation of reactive power compensation for 2.2 kW, 220/380 V, 8.5/5.2A, Δ/Y, 4 P, induction generator has been performed under low wind speed and constant power factor at 0.9. The obtained results can be guidelines for harmonic mitigation of reactive power compensation for grid-connected induction generators inside a nation.
