Design and Application of DC Power Management System of Substation

To further improve the operational stability of the substation DC system and realize the lean operation and maintenance, by analyzing the common problems existing in and new requirements of the DC power management, this paper proposes a design scheme for DC power management system. This design scheme is expected to realize the remote intelligent support, avail future extension of the system, realize integrated processing of the equipment management business information of the DC system, and allow mutual communication of the on-site status monitoring information and history record information of the equipment (including defects, inspection and detection test information) so as to jointly provide complete information for daily management and assistant decision-making of the DC system.
