Modeling of nonlinear loads in high-voltage network by measured parameters

Abstract

The  paper  presents  an  algorithm  for  modeling nonlinear loads connected to the nodes of  high-voltage network. The algorithm is developed on the basis of measured parameters of harmonic conditions. The high-voltage networks are extended. Many  nonlinear  loads  distributed  across  the  territory  of  the region   are   connected   to   them.   An   analysis   of   measured parameters   of   harmonic   conditions   shows   that   they   vary randomly.  The  algorithm  for  modeling  the  nonlinear  loads  is developed    considering    their    probabilistic    properties.    The algorithm   is   illustrated   with   an   example   of   modeling   the nonlinear loads of a railway traction substation and an aluminum smelter shop that are powered by a 220 kV network.
