The invention relates to a communication method and device for a power line low-voltage transformer area, and the method comprises the steps: a first root node receives an access network request message of a target slave node, and the access network request message comprises the identity information of the target slave node; the first root node determines whether the target slave node accesses the low-voltage transformer area where the first root node is located according to the identity information of the target slave node; wherein the target slave node comprises a slave node corresponding to the first root node and a slave node corresponding to the second root node. In the application, the slave node corresponding to the first root node and the slave node corresponding to the second root node in the low-voltage transformer area are configured into one topology network in the communication link layer of the low-voltage transformer area, so that the communication performance of the low-voltage transformer are
