“…Transformers often operate under complex working conditions such as DC bias, high-order harmonics, and over-excitation, Existing research mainly focuses on weakening the effects caused by DC bias from several perspectives, including the grounding method of the neutral point in transformers, as well as the design of windings and iron core structures. In order to address the issue of harmonics, they are mainly eliminated by increasing the number of converter devices and using active or passive filtering [53][54][55][56]. The rational selection of transformer core materials is also an effective method for reducing transformer noise.…”

As an important hub equipment in the power system, the power transformer has increasingly higher requirements for its reliability and safety with the rapid development of the power industry. However, the vibrations and noise generated during its operation not only cause a series of issues such as loose windings, core wear, and fatigue of fasteners, but also lead to anxiety and unease among nearby residents, severely affecting their physical and mental health. Therefore, the generation mechanism and control measures of vibration and noise in power transformers have attracted extensive attention from scholars. The magnetostrictive effect of silicon steel sheets is one of the important factors in the causes of transformer vibration and noise. This paper focuses on the magnetostrictive effect of silicon steel sheets. Firstly, the micro mechanism of magnetostriction is introduced. Secondly, based on current research status, the vibration and noise mechanism caused by magnetostriction are summarized, and the influencing factors, measurement, modeling, and noise reduction methods based on magnetostriction are summarized. Finally, based on the current research status and future development trends, prospects are proposed, aiming to provide references for subsequent research on transformer vibration and noise.

“…In recent years, however, the amount of low and medium power non-linear loads, which are the source of higher harmonics in the grid currents and voltages, has been increased. Therefore, interest in the HAPF operating with lower power loads and reduced passive part has increased [44][45][46][47][48].…”

Control Strategy of 1 kV Hybrid Active Power Filter for Mining Applications

et al. 2021

The paper presents a shunt hybrid active power filter for 1 kV mining applications in configuration with a single-tuned passive filter. The focus is on the method of controlling the filter, with particular emphasis on the influence of network voltage distortion and time delays in control on the effectiveness of harmonic reduction, which is one of the most important aspect of power quality. The low-power loss configuration of a hybrid filter with SiC transistors is shown, as well as the control algorithm which limits the influence of voltage distortion. Theoretical considerations are verified by results obtained from simulations and tests of the hybrid active power filter prototype.
