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


L.I. Kovernikova, Luong Van Chung




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.
