This work focuses on the design and implementation of a D-STATCOM (Distributed Static Compensator) to mitigate current harmonics in non-linear systems. These harmonics, which are integral multiples of the supply frequency, cause issues such as increased heat generation, reduced power factor, voltage distortion, and decreased system reliability. A novel Class Topper Algorithm is implemented for real-time estimation and control of the current harmonics. This optimization algorithm regulates the DC link capacitor voltage fed to the inverter in the D-STATCOM, minimizing harmonics in the source current and improving system performance compared to traditional methods. This proposed algorithm dynamically adjusts control parameters to maintain a constant DC link voltage, leading to reduced harmonics and enhanced power quality. The proposed system is simulated in MATLAB platform, and different PI controller parameters are analysed to achieve various levels of Total Harmonic Distortion (THD %), ensuring compliance with IEEE519-2014 standards. The effectiveness of the proposed D-STATCOM, utilizing the Class Topper Algorithm, is evaluated based on its ability to minimize THD % in the source current while maintaining a stable DC link voltage. This approach significantly improves power system efficiency and reliability.

摘要

This work focuses on the design and implementation of a D-STATCOM (Distributed Static Compensator) to mitigate current harmonics in non-linear systems. These harmonics, which are integral multiples of the supply frequency, cause issues such as increased heat generation, reduced power factor, voltage distortion, and decreased system reliability. A novel Class Topper Algorithm is implemented for real-time estimation and control of the current harmonics. This optimization algorithm regulates the DC link capacitor voltage fed to the inverter in the D-STATCOM, minimizing harmonics in the source current and improving system performance compared to traditional methods. This proposed algorithm dynamically adjusts control parameters to maintain a constant DC link voltage, leading to reduced harmonics and enhanced power quality. The proposed system is simulated in MATLAB platform, and different PI controller parameters are analysed to achieve various levels of Total Harmonic Distortion (THD %), ensuring compliance with IEEE519-2014 standards. The effectiveness of the proposed D-STATCOM, utilizing the Class Topper Algorithm, is evaluated based on its ability to minimize THD % in the source current while maintaining a stable DC link voltage. This approach significantly improves power system efficiency and reliability.
