Özet:

 

This paper studies the impact of load increase and a power system stabilizer   (PSS) on the stability delay margin of a single-machine-infinite-bus system   including an automatic voltage regulator. An analytical method is proposed   to determine the stability delay margin of the excitation control system.   The proposed method first eliminates transcendental terms in the   characteristic equation of the excitation system without making any   approximation and transforms the transcendental characteristic equation into   a regular polynomial. The key result of the elimination process is that the   real roots of the new polynomial correspond to the imaginary roots of the   transcendental characteristic equation. With the help of the new polynomial,   it is also possible to determine the delay dependency of system stability   and the root tendency with respect to the time delay. Delay margins are   computed for various loading conditions and PSS gains. It is observed that   the delay margin generally decreases as the PSS gain and load demand   increase, resulting in a less stable system.
