Power System Study
Generation &Transmission system operators, as well as the scientific community, pay attention to the power system stability and safety. On the present, questions of the power system stability and safety are high actual. It is necessary to find out such preventive measures to avoid severe contingencies in the power system operation, e.g. blackout.
The study of electromagnetic and electromechanical transients is a mature field that plays an important role in the design of modern power systems. There is an effort to find some power system stability margin of which we could say “how stable the power system is” in given condition. Sophisticated models, complex solution techniques, and powerful simulation tools have been developed to perform studies that are of supreme importance in the design and validation of modern power systems. The stability of a system refers to the ability of a system to return back to its steady state without losing synchronism when subjected to a disturbance. Usually, power system stability is categorized into Steady State, Transient and Dynamic Stability.
