outage is ranked according to the severity and the severity is taken on the basis of increased
reactive power generation and real power losses. Outage of other lines has no much impact on
the system and therefore they are not given importance.

It can limit the amount of power that can be transmitted in the system and consequently leads to voltage instability and at times it may also result into total voltage collapse.The main objective of this paper is a comparative investigate in enhancement of volatge stability via static synchronous series compensator (SSSC) and static var compensator (SVC) externally controlled by a POD controller. The new designed P.O.D controller is very efficient for voltage stability under transient conditions. This paper discusses and demonstrates the comparision between the SVC with P.O.D controller and SSSC with P.O.D controller,applied to power system for effectively regulating system voltage for different types of faulted condition. One of the major reasons for installing a SVC is to improve dynamic voltage control and thus increase system load ability during transient condition. This work is presented to present the transmission line voltage stability & machine oscillation damping stability by using SVC & SSSC with POD controller & compared their performance to enhance the stability of a power system. Simulation results shows that SVC with POD controller is more effective to enhance the voltage stability and increase transmission capacity in a power system.

The standard FACTS controller for a particular type of problem is also given. The simulation results give the clear observation of how the FACTS devices improve the power quality. The simulation work is done on Static Var Compensator (SVC) and Static Synchronous Series Compensator(SSSC).SVC and SSSC are providing better power quality under variation of source voltage and when the system is suddenly loaded. The thesis includes the simulation results of the SVC and SSSC only. The future work given as the simulation results of the systems for various power quality problems with all remaining FACTS devices. Then it can be very easy to find an exact FACTS device for a particular type of power quality problem. Installations of SSSC and SVC controllers at all suitable locations will naturally improve the voltage stability of a power system. But, keeping in mind, the cost of the controllers and the optimization task, the number of controllers and their sizes are minimized. Taking corrective actions to keep the system voltage secured under all possible line outage contingency will not be economical or it may not be necessary. Therefore, only the most critical line outage contingency is considered. The line
