ANALYSIS OF THE HIGHEST HARMONIC COMPONENT AND SIMULATION OF A TRANSFORMER WITH A MAGNETIZATION CURVE IN NETWORKS WITH AN ISOLATED NEUTRAL WITH A SINGLE-PHASE SHORT CIRCUIT
Keywords:
Matlab, research, higher harmonic components, zero sequenceAbstract
The article presents the process of modeling the mode of operation of the distribution electric network 6(10)-35 kV with isolated neutral at single-phase short circuits to the ground. Particular attention is paid to the possibility of analyzing the highest harmonic components of the zero sequence in power lines in supertransition and steady-state single-phase short circuit mode. For this purpose, a model of power transformers with higher voltages of 6, 10 and 35 kV was compiled, taking into account the saturation characteristics of the steel core. Modeling of the electric network was carried out in the Matlab software complex. The influence of network configuration, line length in overhead lines was studied.
