- Description
- Abstract: The identification or localisation of distortion sources in power systems should consist of an important milestone towards the achievement of quality electricity supply. However, one of the major impediments to this task remains the non-existence of a unifying technique or method due among others to the versatile characteristics of most harmonic-polluting loads. In this paper, the distribution of active harmonic powers for the fifth, the seventh, the eleventh and the thirteenth harmonic frequency, between two controlled converters connected to the same bus system, is analysed on the basis of the converter’s modes of operation (Rectification or Inversion). The power network under investigation is simulated on the digsilent 14.1 computer program which favourably supports harmonic load flow studies. The harmonic active power trends produced, when converters are either switched in similar or different modes of operation, indicate that the distribution of harmonic active powers is randomly based and therefore independent of the converter operating modes.
