balancing. A comparison of the currents and voltages in S\({}_{9}\) shows the 10 ms gap (\(\pi\) rad phase shift) between the phase voltage and the current on the same phase, which means that it is a reverse transfer of active powers from the secondary of the transformer from the substation (S\({}_{9}\)) to its primary (S\({}_{10}\)--the higher voltage network), at a unitary power factor. The medium voltage network is therefore seen from the high voltage network as an equivalent balanced source of active power. As a result of the intervention of ABCC, the balancing of the power flow is achieved on the phases, which determines the voltage symmetrization on the medium voltage busbars. The voltage asymmetry disturbance does not propagate to the higher voltage network.
