Transient Stability of an Isolated Radial Power Network with Varied Load Division

The transient stability of an isolated radial power system is investigated, by the help of an available digital computer program. The load is kept constant but its division is varied among the three load components, namely, synchronous motors, induction motors, and static load. Performance diagrams of the rotating units are shown for both stable and unstable system operations and a stability limit curve is presented in a triangular co-ordinate system correlating the load components. Finally, the results are analyzed.
