Abstract: The present invention relates to a method for automatic identification of an application network topology for power distribution network control which belongs to the field of electric power automation. The method comprises the following steps: 1. statically configuring attributes of a switch; 2. determining, by a power distribution network intelligent terminal STU, whether a query trigger condition is satisfied; 3. sending, by an inquirer, a query command to initiate the query into an application network topology; 4. replying to the query command; 5. receiving the query command; 6. checking the integrity of the switch attribute information; and 7. forming an application network topology.
