Method and apparatus for generating physical network topology

An apparatus comprising:

• a memory configured to store instructions;
• and
• a processor coupled to the memory, wherein, when executed by the processor, the instructions cause the apparatus to:
• obtain a first data transmission parameter between a first-level node and each node in a first node set, wherein the first data transmission parameter comprises a data transmission distance or a data transmission time, wherein the first-level node is located on a first-level power distribution device in a power distribution grid, wherein the first node set comprises a first node located on a first power distribution device at another level in the power distribution grid other than the first-level power distribution device, and wherein the first node is a first child node of the first-level node;
• determine, from the first node set and based on the first data transmission parameter, a second-level node directly coupled to the first-level node;
• and
• generate a physical network topology of the power distribution grid,
• wherein the physical network topology comprises a first connection relationship between the first-level power distribution device and a second-level power distribution device on which the second-level node is located.

A computer program product comprising computer-executable instructions that are stored on a non-transitory computer-readable storage medium and that, when executed by a processor, cause an apparatus to:

• obtain a first data transmission parameter between a first-level node and each node in a first node set, wherein the first data transmission parameter comprises a data transmission distance or a data transmission time, wherein the first-level node is located on a first-level power distribution device in a power distribution grid, wherein the first node set comprises a first node located on a first power distribution device at another level in the power distribution grid other than the first-level power distribution device, and wherein the first node is a first child node of the first-level node;
• determine, from the first node set and based on the first data transmission parameter, a second-level node directly coupled to the first-level node;
• and
• generate a physical network topology of the power distribution grid,
• wherein the physical network topology comprises a first connection relationship between the first-level power distribution device and a second-level power distribution device on which the second-level node is located.
