Advanced PMU-Based Applications

  • Adaptive Out-of-Step Protection (AOOSP) provides fast detection of transient instability based on angle difference and quick determination of forced-generator tripping to secure transient stability

  • Real-Time Voltage Stability Margin (RTVSM) offers a scalar magnitude measuring the proximity of the power systems to the voltage collapse point, thus improving the visibility of load margins through aggregated local loads

  • Advanced Overload Protection Scheme (AOLPS) incorporates several key features such as overload protection based on dynamic line rating, conductor temperature calculation, and adaptive load shedding scheme
