Identification of relative location voltage sag source using phase space technique

This paper introduces an alternative method for voltage sag source location based on phase space based disturbance powers. It is done to avoid the wrong and inconclusive detection of conventional disturbance power method proposed in the literature. Unlike in the case of the traditional method, the proposed method first transforms the recorded voltage and current during the sag event to obtain some special features before calculating the new version of disturbance powers. The effectiveness of the proposed method has been verified through simulation. The studies show that the presented method can correctly detect the location of voltage sag source.
