A Station Domain Islanding Detection Method Based on Topology Analysis

The communication-based islanding protection in the station domain can quickly realize the islanding detection without detection blind area and no disturbance will be injected into power system. However, the current station domain islanding detection method does not have universal applicability. In this paper, the topology analysis method is introduced into the islanding detection in the station domain. The islanding detection of power systems with different topological structures can be realized by modifying the parameters. The voltage grade of each node of the power system is used to optimize the search path of topology analysis. In addition, the circuit breaker position is checked to enhance the reliability of the islanding detection method.
