Power System Severity Analysis under Generator Outage Condition

S. Ravindra, V. C. Veera Reddy, S. Sivanagaraju

Now a day because of the continuous increase in power demand on a power system increases the importance of the power system severity analysis for secured operation. The contingency in a power system may be because of the outage of transmission lines or the generators. Out of which, generator outage condition is the most critical one. In this paper, the power system severity is analyzed under generator outage condition. The most sensitive generator(s) in a given system is identified using generator shift factors. The complete methodology of the proposed methodology to analyze the power system severity in terms of transmission line loadings and bus voltage magnitudes is analyzed on standard IEEE-14 bus test system with supporting numerical and graphical results.
