Non-linear or unbalanced loads, etc., are the typical causes of asymmetry in the three-phase systems. The typical difficulty that exists in many methods of symmetrisation is the calculation of the adjusted values (regulable parameter). In this paper, we propose a new method to overcome all of the above problems, which includes: introduction of the new dependence of the basic electrical quantities (voltages and currents) on the controllable values of the static compensation devices; the proposed new method of overcoming the asymmetric operation regime in the three-phase systems, in which we aim to reduce the number of compensating devices.
