Abstract : As demand of quality and reliability of
electric power is continuously increasing, Power
Quality has now become a important aspect in the
current power scenario. Power quality determines
quality and ability of electric power available at the
consumer end. Maintaining voltage, frequency and
phase to desired level allows electrical systems to
provide quality and reliability of power without
considerable loss of performance or life. poor power
quality can be caused due to failure of loads and
sudden switching of heavy electrical loads in the
network, which mainly result in voltage sag and
swell , disturbances in loads may also results in
voltage fluctuation. However voltage flicker and
interruptions are the most common problem which
effects power quality.
Voltage fluctuation is considered one of the most
important power quality disturbances due to its
greater frequency of occurrence as compared with
other power quality problem. This problem can be
compensated to greater extend by using Flexible AC
Transmission Systems (FACTS) like STATCOM,
UPFC , DVR etc. Out of which STATCOM also
known as a "static synchronous condenser"
("STATCON"), gives better performance than SVC.
It is based on a power electronics voltage-source
converter VSC it can supply or absorb reactive power
to the electrical network. If it is connected to a source
of power it can also provide active power. If this stat
com is used in distribution network it can be called as
D-Stat com (Distribution Static Compensator). D-
STATCOM is a shunt device which is generally used
to solve power quality problems in distribution
systems by injecting current. It is used to improve
power factor, maintain constant distribution voltage
and eliminate harmonics in a distribution network.
In addition to this a case study is planned taking the
parameter of industrial load. This work describes the
working of STATCOM to provides voltage support to
sensitive loads and will be simulated by using
MATLAB/SIMULINK. The control approach
presented will be able to compensate for any type of
voltage sags and swells
