A Hybrid Multilevel Inverter DSTATCOM Topology to Compensate Reactive Power for Nonlinear Loads

Duggirala Ajay Kumar, M Ramesh


This task proposes an enhanced cross breed conveyance static compensator (D-STATCOM) topology to address some viable issues, for example, control rating, channel estimate, pay execution, and power misfortune. A LCL channel has been utilized at the front end of a voltage source inverter (VSI), which gives better exchanging sounds disposal while utilizing considerably littler estimation of an inductor as contrasted and the conventional L channel. A capacitor is utilized as a part of arrangement with a LCL channel to diminish the dc-connect voltage of the D-STATCOM. This thusly diminishes the power rating of the VSI. With lessened dc-interface voltage, the voltage over the shunt capacitor of the LCL channel will be likewise less. It will decrease the power misfortunes in the damping resistor as contrasted and the conventional LCL channel with uninvolved damping. Accordingly, the proposed DSTATCOM topology will have decreased weight, cost, rating, and size with enhanced effectiveness and current remuneration capacity contrasted and the conventional topology. An orderly strategy to outline the parts of the inactive channel has been introduced. A multilevel fell H-connect is executed in the VSI task of a D-STATCOM topology. The viability of the proposed DSTATCOM topology over customary topologies is approved through MATLAB/SIMULINK programming.
