An algorithm for on-line identification of faulty components in 110kV urban power network is presented. Considering the particular characteristics of automation equipment in urban power systems, the topological correlation method is adopted in this algorithm. First, the topological configuration is formed by use of real-time switching information and the outage area is quickly searched out. Then the faulty components are determined by protection action information and the determined result is checked by on-line telemetering and telecommunication information, thus, the real-time fault diagnosis of urban network is implemented quickly and effectively. This algorithm is fast, reliable and versatile for 110 kV network. With this algorithm, the faulty components, the miss operation and the mal-operation of circuit breakers as well as the faults occurred in 10 kV lines can be identified and diagnosed quickly and correctly, therefore, the need of on-line operation of control center for middle and small scale urban network is met.
