Design of an Improved Star Configuration Based Statcom with H – Bridge Concept

Abstract

The main aim of this paper is to design a STATCOM which has the capability of compensating the fault and to overcome the conduction losses faced by the conventional STATCOM with traditional H-Bridge structure the future control procedures bestow themselves not only to the current loop control but also to the DC capacitor voltage control. With concerns to the current loop control, a nonlinear controller established on the passivity-based control (PBC) theory is used in this cascaded STATCOM. The capacitor voltage control, overall voltage control will control by embracing a proportional resonant controller. Clustered balancing mechanism will achieve by shifting the modulation wave vertically which can be easily executable in a field-programmable gate array. An artificial fault will be injected for a limited time period duration. Real and reactive power will be maintained for the compensated voltage and current. This work carried by using MATLAB /SIMULINK simulation tool.
