Abstract
Control strategy of shunt active filter based on forming the network current vector proportional to the instantaneous phase voltage vector with partial decrease of zero-sequence component that gives advantages of power losses in the four-wire cables is proposed. The optimal coefficient of decrease is determined by the ratio of specific active resistance values of the phase and neutral conductors, i.e. for each brand of four-wire power cable of three-phase network is its optimal coefficient of decrease of zerosequence component that provides a minimum of active power losses. Comparison of control strategies in value of instantaneous reactive power consumed by the three-phase source was performed. References 9, figures 5.
