Abstract	In this paper, a new approach for detecting realtime matching for controlled islanding based on the correlation coefficient of generators is proposed. In this approach, by online measuring generators rotor angle oscillations, the correlation coefficients between all pairs of generators are evaluated. Based on the evaluated correlation coefficients, coherent groups of generators are identified. Then, using correlation coefficient of coherent groups, splitting indices between coherent groups are evaluated. Following a disturbance, in the case of the risk of splitting coherent groups towards islanding, the values of splitting indices start to increase detecting tendency of coherent groups towards splitting state. The proposed approach is demonstrated on the IEEE 39-bus system with promising results.
