Over recent years increasing demand for high quality, reliable electrical power and increasing number of distorting loads leads to an increased awareness of power quality. The Power Quality disturbances arises when the decided standard limit of voltage, current and frequency for safe operation is exceeded. This leads to suffering of utility distribution system from service interruption, outages and false operation or failure of end user equipment which results in financial loses. Hence it has

Many compensating devices has been put forward by researchers and power engineers to curb this problem of power quality issues. Of recent developments, the involvement of D-STATCOM, a Voltage Source Converter has been instrumental. This paper puts forward the development of such a D-STATCOM in a power distribution network. The development of the controller, the advantages of installation of the compensating device with respect to voltage profile management, power quality has been discussed. The simulation of the proposed controller has been done in MATLAB Simulink and its performance based on various aspects has been done.
