The object of research is current harmonic filters as universal means of improving the electromagnetic compatibility of converting equipment devices with the power supply network.
During the reporting period, research work was performed according to the relevant stage of the work plan for 2024. The scientists developed mathematical models of hybrid filters and modeling new schemes of active, passive and hybrid filters, which determined their impact on the quality of power supply.
In particular, the optimal ratio of contributions to the effect of muting higher current harmonics due to the action of passive and active components of hybrid filters was determined and optimized the parameters of hybrid filters, taking into account their contribution of active and passive parts in the quality of electricity.
It is established that despite the slightly lower quality PF and cos φ, the scheme by type "triangle" has better indicators of the level of harmonic current distortions and less deviation of the active value of the input current from the first harmonic, the compensation of which should be calculated by the active corrector of the current for hybrid configuration. The results are of scientific and practical value, meet international standards and can be used to improve electromagnetic compatibility of converting equipment with an industrial power supply network of limited power. Research in this direction allows to save energy by improving the electromagnetic compatibility of converting equipment with the power supply.
Key words: QUALITY OF ELECTRICAL ENERGY, COEFFICIENT OF CURRENT HARMONICS, PASSIVE FILTER, ACTIVE FILTER, HYBRID FILTER, DISTORTION COMPENSATION.
