A New Hybrid Topology of D-STATCOM for Power Quality Improvement
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2016, Vol 4, Issue 11
Abstract
This work proposes an enhanced new breed conveyance static compensator (D-STATCOM) topology to address some down to earth issues, for example, power rating, filter size, performance of compensation, and power misfortune. A LCL channel has been utilized at the front end of a voltage source inverter (VSI), which gives better exchanging music end while utilizing much 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-interface voltage of the D-STATCOM. This thusly diminishes the power rating of the VSI. With decreased dc-connect voltage, the voltage over the shunt capacitor of the LCL channel will be likewise less. It will diminish the power misfortunes in the damping resistor as contrasted and the customary LCL channel with uninvolved damping. Accordingly, the proposed DSTATCOM topology will have lessened weight, cost, rating, and size with enhanced proficiency and current remuneration capacity contrasted and the customary topology. A deliberate system to outline the segments of the uninvolved channel has been displayed. A multilevel fell Hbridge is executed in the VSI operation of a D-STATCOM topology. The viability of the proposed DSTATCOM topology over customary topologies is approved through MATLAB/SIMULINK software.
