Abstract
- In this study, shunt compensation using conventional split capacitor‐based distribution static compensator is presented. A new state feedback‐based switching control is proposed to avoid capacitor voltage divergence and to achieve load compensation, simultaneously. Compared with conventional control used for dc‐link voltage regulation, the proposed control reduces the requirement of proportional–integral controllers. The proposed control also nullifies high‐frequency components from the source and neutral current with minimum total harmonic distortion, provides precise dc‐link voltage regulation, thus, minimising the dc power loss. The reference generation for control variables along with the switching control is discussed. To demonstrate the superiority of aforementioned scheme, three‐phase four‐wire distribution system with shunt compensator under steady state as well as transient condition, is considered. To show the simplicity and effectiveness of the proposed control, simulation studies are performed along with the frequency‐response analysis using MATLAB environment. Finally, the detailed simulations using PSCAD/EMTDC and experimental results are provided to validate the efficacy of the proposed control. [ABSTRACT FROM AUTHOR]
