This paper proposes a new inter area angle stability prediction algorithm. This algorithm does not require any prior knowledge of system state as it operates directly from measurements drawn from SPMUs. The proposed predictor foresees the system stability state before elapsing the first swing i.e. assessing system stability in advance. Applying the Synchronized Phasor Measurement Units (SPMUs) for the power systems, inter-area stability can be predicted in a proper time. Since the need for real-time Out-Of-Stability (OOS) algorithms becomes a very important issue in the modern power system networks. So that, the objective of this paper is producing an algorithm for Fast Stability Detection (FSD) before elapsing the first swing period using enhanced equal area criteria in time domain. For the above objective a comprehensive analysis with various faults are performed in a single machine infinite bus test system.
