The invention relates to the field of intelligent power grids. The invention relates to a power grid, in particular to intelligent power grid data distribution. The intelligent digital distribution system comprises an intelligent digital distribution stacking structure formed by a plurality of intelligent digital distributions, each intelligent data distributor is connected with a network management client platform through an Ethernet switch; the intelligent digital configuration works on the main channel by default; at least one standby channel is connected through an electronic switch; whenthe intelligent digital configuration does not receive the instruction, information is transmitted through the main channel, after alarm information of the network management client platform is received, the network management client platform sends a switching instruction to the intelligent digital configuration, after the intelligent digital configuration issues a switching confirmation instruction, the main channel is switched to one standby channel, and the channel switching process is completed. According to the invention, when the main SDH transmission equipment or the optical cable fails, the transmission link can be switched remotely and timely, the failure can be handled timely and effectively, the operation reliability of the 2M core service is greatly improved, and the reliability of the power grid is ensured.
