Abstract This thesis introduces a new study about the produced harmonic resonance overvoltage (HRO) during the energization of the main power transformers in grid-connected wind farms. The thesis studies some affecting factors on the produced HRO. It investigates the effect of the lengths of the overhead transmission lines (OHTLs) and the unloaded on-line transformer on the HRO. In addition, it investigates the effect of the wind farm feeders, connected to the secondary side of the on-line transformers, on the HRO |
