Audible noise of hybrid AC / DC overhead lines : Comparison of different prediction methods and conductor arrangements

  title={Audible noise of hybrid AC / DC overhead lines : Comparison of different prediction methods and conductor arrangements},
  author={S. Hedtke and Luciano E Zaffanella and Martin Pfeiffer and John Chan and Christian Michael Franck and Justin Bell},
The concept of partial conversion of existing tower phase arrangements to hybrid HVAC/HVDC overhead lines has become an attractive solution to meet the demand for higher power transmission capacity. Due to mutual AC/DC coupling effects, corona phenomena such as audible noise can be affected and have thus to be predicted accurately. In this paper, existing empirical equations are used to predict corona audible noise for several hybrid AC/DC tower geometries and conductor arrangement scenarios…
