Abstract: This application relates to a method and an apparatus for identifying a topology of a power line low-voltage transformer area. The method may include: A primary node obtains characteristic data, where the characteristic data includes: first characteristic data between any two secondary nodes that have a direct connection relationship in a plurality of secondary nodes in the low-voltage transformer area. The primary node identifies the topology of the low-voltage transformer area based on the characteristic data, where the characteristic data includes at least one of delay data or channel quality data, the delay data is a first delay for transmitting information on a power line between the two nodes that have a direct connection relationship, and the channel quality data is quality of a power line channel between the two nodes that have a direct connection relationship.
