Abstract
With the popularization of distributed new energy and the promotion of green and low-carbon energy transformation to achieve carbon peak and carbon neutrality goals, a large number of new elements such as photovoltaics, electric vehicle charging facilities, and energy storage equipment are integrated into the distribution network substation, which will generate multiple harmonics in the substation area. For the high proportion of zero sequence harmonics in the transmission line, magnetic flux compensation zero sequence filters can effectively filter out and improve the harmonic environment. However, the adaptability of zero sequence filters may vary under various working conditions, and may even cause damage to the line or equipment. This article mainly analyses the principle of magnetic flux compensation and builds a filtering circuit model using MATLAB/SIMULINK, Analyzing the filtering effect of zero sequence filters under standard operating conditions and three-phase imbalance can be used as a basis for optimizing the parameters of zero sequence filters, which has great value and significance for the design of zero sequence filters.
