Abstract
In modern power systems, a mixture of alternating and direct current is increasingly used for generation, transmission, distribution and consumption. Various types of electrical energy conversion devices, such as rectifiers, inverters and DC converters are used. Their effect on the dynamic characteristics of the power system also tends to become more complicated, not only leading to problems such as harmonic pollution and harmonic resonance in power systems, introduce harmonics and resonance into the power system and cause secondary hazards such as low operating efficiency and deterioration of the operational characteristics of electrical equipment. Based on these problems, an induction filtration solution based on induction filtering transformers is proposed to improve the quality of electricity on the side of the substation network, and the technical characteristics of the induction filtering transformer are analyzed. In this article, the basic principles of inductive filtration technology are analyzed, the inductive filtration distribution transformer structure is designed, the circuit of the inductive filtration distribution transformer and filtration system in the distribution network is established, and the parameters of the transformer and filtration system are determined. By creating a mathematical model and a circuit model of an inductive filter transformer, the principle of harmonic suppression of an inductive filter distribution transformer is analyzed. The theory and method of regulation and filtration of electrical induction have deeply revealed the electromagnetic potential of power transformers. In combination with power electronic devices, this not only effectively implements two-way power quality management in the power system and among users, but also provides a win-win situation in the interests of both energy operators and electricity consumers. This also theoretically reduces the converter performance to achieve efficient and inexpensive filtration.
