Abstract
Recently, with the development of the city center around the substation, complaints about noise are increasing. Shunt reactors are a major source of noise in substations. To reduce the noise of the shunt reactor, research on the magnetic circuit and structural design for optimizing the compression distribution are important. In this paper, the magnetic flux distribution and compression distribution of the magnetic element were calculated using a finite element analysis program, and the reduction effect was analyzed by measuring the noise. Introducing a study that improved the distribution of magnetic flux by applying a magnetic flux control panel to the vibration caused by the magnetomotive force generated from the magnetic element, and reduced noise by changing the shape of the compression structure.
