The STATCOM is a shunt connected voltage source converter using self-commutating device and can
be effectively used for reactive power control. Its principle of operation is similar to that of a synchronous condenser.
This paper describes the linear modeling of STATCOM along with design of current and voltage controllers. The
designed controllers with variation of DC-link voltage have been applied to the STATCOM and suitable DC-link
voltage has been selected on basis of spike and over shoot of the responses. The values of the passive parameters
decided on basis of selected DC-link voltage are used for the design and fabrication of a STATCOM. All responses
are obtained through MATLAB SIMULINK tool box and presented here for clarity of the control strategy.

IJCERT is peer-reviewed scientific Research journal to endorse conservation. We have not put up a paywall to readers, But running a monthly journal costs is a lot. IJCERT has been changed the publication policy from Free publication to pay because of increasing the maintenance cost and other editorial charges. The understanding and cooperation of the author are highly solicited.we still need support to keep the journal flourishing. If our readers help fund it, our future will be more secure.
