Модульные многоуровневые преобразователи для симметрирования и фильтрации сетевого напряжения в окрестности тяговой подстанции переменного тока

Abstract

Questions of use of a prototype of the active filter executed according to the scheme of the modular multilevel converter (MMS) for balancing and a filtration of voltage on tires of the substation feeding traction substations of the railroad of alternating current are considered. Results of tests of a prototype of the active filter are given. The technique and results of calculation of asymmetry and voltage waveform distortion on tires of 110 kV of PS "Skovorodino" under operation of the active filter on the basis of a MMS is considered.
