Implementation of Voltage Stability System in Distribution Network by using D-STATCOM

This project work presents a proposed D-STATCOM system, Which is implemented in the distribution network. In the present scenario, the customer or consumer should be supplied with a quality power. The power quality issues like voltage sag, swell, lightning surges etc, can be reduced by using several advanced techniques. Among all these power quality issues voltage sag is considered and has been compensated in this project work by using D-STATCOM. The major advantage of D-STATCOM is that instead of installing the compensating device in the transmission and distribution line, the D-STATCOM unit is implemented at the consumers premises to maintain stable voltage for the connected electrical equipment’s and also to provide safe operation of the electrical equipment’s by extending their life time. The software ie., implemented by using MATLAB Simulink and the results are also verified experimentally by a hardware unit
