A METHOD OF FILTERING FOR HARMONICS WITH VARIABLE FREQUENCY IN THE LOW VOLTAGE POWER SYSTEM

  • Lê Việt Cường, Doãn Thanh Bình, Nguyễn Tùng Linh

Abstract

Today, as the industrial load grows rapidly, electrical devices are non-linear loads that use many power elements, resulting in high frequency harmonics on the distribution grid, affecting quality. electricity and equipment. The use of harmonic filters is the solution that is widely applied in many cases due to its many economic and technical advantages. Therefore, the study of harmonic filters to improve power quality is a requirement. In this paper, the authors propose a method of passive filtering for harmonics with variable resonance frequency based on the load configuration. This harmonic filter with variable frequency based on the load both meets the efficiency of filtering harmonics in the power system and has a very competitive price because of fewer reactors design.
