AB  - Power quality and the dynamic performance of
the distribution system in Pakistan is poor because of
weak and out-of-date system. It is unable to deliver the
required reactive power in case of various system
disturbances. Distribution Static compensator (DSTATCOM)
is an important compensator which is able to
enhance the power quality and dynamic performance of
the distribution system. In order to improve power quality
and dynamics performance of the distribution system
effectively a more robust and optimal control algorithm is
required for D-STATCOM. Hence, in this research work
an improved and optimal control algorithm have been
designed for D-STATCOM. In improved control scheme
SRF theory control is used for the reference current
generation. For the generation of gat pulses for VSC of
D-STATCOM level shifted PWM scheme have been used
because it offers very good performance for reduction of
harmonics distortion. The designed device is implemented
in MATLAB-Simulink and is capable to deliver good
reactive power compensation under various loading
environments such as inductive load, capacitive load and
under abnormal faults conditions.
