| چکیده مقاله: |
| This paper proposes a novel Out-of-Step protection technique based on synchronized phasor measurements and concept of Equal Area Criterion (EAC). In any disturbance, in the control center, generators are clustered into safe and risk groups based on the concept of Boundary of Angle Oscillations. At the same time, a local stability index also is sent to the control center from each generator. The latter is obtained by local phasor measurements based on EAC concept. Generator is known as unstable if it belongs to the risk cluster at the control center and its stability index is lower than one. For each generator, the acceleration area during fault condition is calculated directly using the generator output power and rotor angle measured in real-time. As soon as the fault is cleared, the deceleration area is predicted with the help of post-fault curve estimated by the least square method. The proposed technique is verified on the New-England 39-Bus test network |
