A New Multilevel Inverter Topology of D-STATCOM to Compensate Reactive and Nonlinear Loads
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2017, Vol 5, Issue 1
Abstract
This work proposes an enhanced hybrid distribution static compensator (D-STATCOM) topology to address some practical issues like power loss, filter size, performance etc. A LCL filter has been utilized at the front end of a voltage source inverter (VSI), which gives better exchanging harmonics elimination while utilizing much littler estimation of an inductor as contrasted and the conventional L channel. A capacitor is utilized in as eries with LCL channel to diminish the dcinterface voltage of the D-STATCOM. This thusly lessens the power rating of the VSI. With lessened dc-connect voltage, the voltage over the shunt capacitor of the LCL filter will be additionally less. It will decrease the power misfortunes in the damping resistor as contrasted and the conventional LCL filter with latent damping. In this way, the proposed DSTATCOM topology will have decreased weight, cost, rating, and size with enhanced proficiency and current pay capacity contrasted and the conventional topology. A deliberate methodology to outline the segments of the inactive filter has been displayed. A multilevel cascaded-H-bridge 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 programming.
