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 . the present method for automatic identification of an application network topology for a power distribution network control has few calculations and can be executed with high speed , ensures the integrity and reliability of information , and is particularly suitable for distributed intelligent control of the power distribution network . the establishment of the application network topology is distributed to each power distribution network intelligent terminal stu , thus reducing heavy calculation , and is suitable for applications having relatively few embedded system software and hardware resources .
