Abstrac
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.
