Abstract
The article deals with the problem of development and implementation of current and voltage curve correction systems in networks of mining and oil and gas processing enterprises using active filters based on IGBT transistors. The estimation of existing schemes of connection of active filters is given, their advantages and disadvantages are emphasized, the basic principles and features of their work are considered. The structure and control algorithm of the sequential active filter providing predictable compensation of harmonic components are given. The relations for its realization using the method of symmetric components and the theory of rotating coordinate systems are obtained.
