FIELD: transport. ^ SUBSTANCE: invention relates to complex consisting of drives (1) and drives electric supply from three-phase alternating current mains (2). The complex comprises input unit (4) connecting drives with mains and drives control system (3). Input unit (4) contains converter (5) which is made capable to transform three-phase alternating current into high-voltage direct current and which is connected with bidirectional power line (6); charger/discharger (9) connecting accumulator (10) with power line. In the power line (6), at least one protective circuit-breaker (7), communication interface (8) and at least one of the drives is installed. The interface is linked with central unit (13) connected with control system to exchange signals in power line with communication interface (100) of at least one of drives. Each drive includes reversing motor (101) connected with communication interface to supply power and execute control via this interface. ^ EFFECT: simplification of integrating drives and their power supply system complex architecture. ^ 9 cl, 3 dwg |
