In this paper an actual problem – the controlling of voltage regime in distributed circuit of mineral raw industry with the help of for power transformers. Particular attention spare for in- vention of automatic controlling block for equipment of voltage control under the power using theory of fuzzy logic. There are the results of mathematics and computer modeling.
In this paper an actual problem – the reduction of line current harmonic is discussed with the example of fuzzy controlled APF design. This is the most perspective decision that make possible to reduce line current harmonic and to correct factor of sinusoidal view of line of voltage. Results of testing are corroborate the efficiency of APF.
