In terms of grid operation, for scenarios where new energy and conventional power sources share transmission channels with limited capacity: due to the high uncertainty of new energy output, conventional units need to be frequently adjusted to prevent the shared channel from exceeding limits; the power flow in new energy export channels is complex and variable, reducing the controllability of grid power flow dispatching. To meet the actual on-site ring-closing application requirements, the novel dry-type voltage regulating and phase-shifting transformer for distribution network enables ring-closing transfer supply under extreme conditions with large amplitude and phase differences.

The novel dry-type voltage regulating and phase-shifting transformer for distribution network combines controllable voltage regulation technology and phase-shifting technology, enabling flexible voltage regulation and phase adjustment in power systems. It is beneficial for improving the stability and flexibility of the power system and is suitable for various scenarios requiring precise control of voltage and phase.

Product Features:

1.Ring-closing Transfer Supply: By adjusting the output voltage vector of the phase-shifting transformer, approximate same-power-source ring-closing is achieved, reducing risks caused by ring-closing power flow changes.
