Abstract
The objective of this paper is to determine
the improvement in transient stability of IEEE 9Bus
system using STATIC VAR compensator. SVC is one of
the FACTS devices which can make the power supply
more efficient and reliable. Power systems are
continuously subjected to various types of disturbances
which in turn cause the problem of losing stability.
Transient stability is one of the most important stability
of the power system. The loss of Transient stability is
due to varies disturbances like faults, sudden change in
loads and tripping off the lines after fault or heavy loss
of loads. Power systems are Operating nearer to their
stability limits due to economic and environment
reasons. In under damped Power systems disturbances
lead power system into unstable state. So, the tools for
mitigating such a sensitive problem have an important
significance. Static VAR Compensator (SVC) can
control reactive power and therefore it is used to
improve transient stability as well as the voltage
profile. The proposed work includes IEEE 9-Bus Test
system incorporated with SVC controller using
Mipower Software. The simulation shows how the
oscillations are damped out with SVC controller.
