“…The security and consistency is enriched in power system with the help of contingency analysis [2]. Contingency analysis is a simulation investigation method which associate various problem in power system, come up with the optimal response under circumstances situation [3]. Fuzzy controller is the effective tool to solve the different types of problem in power system [4].…”

In power systems, voltage stability perform the major role in design and its operation. Major system failures are occur due to voltage variability and breakdown. To meet and compensate the rising power demand of regular usage in modern trends, transmission networks are enormously loaded which create the voltage instability. Contingency analysis is a recognized energy managing tool. It calculate the violation in the transmission line. In this paper a computational controller fuzzy system is suggested to handle the transmission line outage and overload in other branch kind of problems in Power system. The efficiency of power transmission system with fuzzy controller is inveterate by computation of various parameters of transmission bus under different loading situations. For the contingency analysis the transmission power flow several methods have been developed. Fast Decoupled load flow program is the effective method which provides a fast and effective solution to the contingency analysis in the transmission system and also it is incorporate with matrix alteration formula which gives additional advantage for the system.

“…Moreover, the issue of transient voltage stability of dynamic loads such as induction machines is analysed. In the more recent reference [6] the authors use sensitivities to carry out contingency filtering and ranking with respect to voltage dips. Furthermore, the assessment addresses power quality issues and short-term voltage stability.…”

The paper introduces an approach to investigate voltage sags, which are caused by large generator rotor swings following a transient disturbance. Therefore, the method exploits sensitivities derived from the algebraic network equations. These provide information on the impact of a generator on the voltage magnitude at a load bus and the effect of load variation on the generator's power injection. It is shown that these sensitivities give valuable information to identify critical generator-load pairs and locations for applying preventive control measures.
