Abstract:
The most common problem in a heavily loaded electrical network is voltage disparity,
due to continuous load variations. The continuous increase in energy demand requires
that a methodology be developed to be able to meet the energy demand. Therefore, such
devices are needed, which can minimize energy loss and voltage drop in the power
supply network. FACTS devices are a valuable option for improving voltage drop and
reactive power in place of capacitors and shunt reactors. This article investigates the
effects of the Static Variation Compensator (SVC) on the voltage stability of a power
system. This paper will discuss and demonstrate how SVC has been successfully applied
to the power system to effectively regulate the system voltage. One of the main reasons
for installing an SVC is to improve dynamic voltage control and thus increase the load
capacity of the system. This article introduces SVC modeling and simulation in
MATLAB / Simulink. In this article, an SVC is used to regulate the voltage in a power
system. When the system voltage is low, the SVC generates reactive power (capacitive
SVC). When the system voltage is high, it absorbs reactive power (inductive SVC). SVC
is rated +100 Mvar capacitive and 50 Mvar inductive. SVC more effectively improves
voltage stability and increases transmission capacity in a power system.
Description:
SVC is the favorite apparatus for dynamic support of reactive power in high voltage
transmission networks. Thanks to its essential ability to control variables on a cycle-by-cycle
basis at high speed, it will counteract the often daring voltage dips that survey along with
network outages. These extremely dynamic actions, wherever the growing procedure of
induction motors (such as those in air preparing divisions and wind turbine generators)
pressures the grid, will require an SVC to maintain grid voltage and protection the grid.
Ability to recover in case of failure. In addition, if the SVC consist of variable absorption
capacity, it will efficiently conquer short-term surges that may perform when clearing the
error. The SVC will ensure that the mains voltage is continuously kept within suitable
restrictions.
