【 摘 要 】
According to the requirements of the advanced applications in smart substations, hierarchical topology analysis method based on electrical bays is proposed in this paper. Based on the node connection relationships of each device in the substation, all primary devices can be organized into the hierarchical structure as "transformer (winding) - bus - electrical bay". The typical 3/2 circuit breaker connection and the inner bridge connection are also recognized. On this basis, the identification of the static topology and the judgment of the dynamic connectivity in the main wiring diagram of the substations are realized, which is helpful in the quick search of the devices. The topology analysis method introduced in this paper will effectively support the advanced applications for substations such as fault diagnosis, state estimation, the status analysis of electrical bays and so on.
