| Abstract: This paper assesses the transient stability analysis of the expanded 16 machines, 330KV Nigeria Grid System through coherent generators aggregation based on equal acceleration and velocity concept. The technique involves performing the electrical proximity test on the system generators under fault condition to select the study area generators, subjecting these generators to coherency check through inertia and damping indices conditions; and construction of dynamic equivalents representing each pair of coherent generators. The result led to reduction of 16 machines system to 13, thereby simplifying the network complexity and requires minimal computer time as well as memory space. |
