power quality problem is observed as a non standard voltage, current and frequency with results in failure or disturbance in operation of receiving end user machines. Disturbance in utility of networks, sensitive industrial loads and critical commercial operations faces different types of outage and service interruption which effects financial losses. After restructuring of power system and shifting trend towards distributed and dispersed generation, the problem of power quality is going to take newer structure. In developing countries like India, where the variations and fluctuation of power and frequency and many such others determinants of power system which affects power quality of distribution line are themselves a serious problem, It is very indispensable to take positive steps in this direction. The present work is to identify the notable concerns in this area and hence the measures that can improve the power quality of power are recommended. This paper propose the improvement of voltage sags, harmonics distortion and low power factor using Distribution Static Compensator (D-STATCOM). The model build on the principle of voltage source converter (VSC).The D-STATCOM injects a current into the system to appease the voltage sags,to improve harmonics disturbances and low power factor. The simulations were performed using MATLAB SIMULINK .
