The modernization of interconnected power systems requires a shift from local protection schemes to synchronized Wide-Area Monitoring, Protection, and Control (WAMPAC) frameworks. This paper proposes a novel architecture for realtime Transient Stability Assessment (TSA) and coordinated emergency control using synchrophasor data provided by Phasor Measurement Units (PMUs). We introduce an adaptive Transient Stability Index (TSI) based on the synchronized energy function method, which enables the detection of impending instability within cycles of fault clearance. Furthermore, a hierarchical emergency control strategy—combining Generator Tripping (GT) and Under-Frequency Load Shedding (UFLS)—is implemented to prevent large-scale blackouts. The architecture accounts for communication latencies and data packet loss, ensuring robustness in realistic Wide-Area Network (WAN) environments. Validated on the IEEE 68-bus New England/New York test system, the results demonstrate that the proposed WAMPAC scheme achieves a 98.5% accuracy in stability prediction with a control response time under 150 ms.
