Structure, algorithm and hardware implementation of an automatic system for minimizing current and voltage waveform distortion in electric networks of mining-and-processing and metallurgical facilities have been developed. The system permits to provide continuous automatic control and analysis of electrical energy quality indices, as well as rational control of energy consumption mode, without functionality loss and distortion of results.
