Гармонічні складові напруги та струму в магістральних мережах

Abstract

The mathematical model of AODCTN-333000/750/330 autotransformer has been presented in the paper. Electric and magnetic systems of autotransformer are simulated. There has been conducted the research of harmonic composition of voltage and current on the simulation model of network with one 750 kV transmission power line. Total harmonic distortion (THD) of current and voltage in one 750 kV transmission line for geomagnetic currents 50...200 A in neutral conductors of autotransformers have been determined at active and active-inductive load.
