Abstract

Notice of Retraction-----------------------------------------------------------------------After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IAES's Publication Principles.We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.The presenting author of this paper has the option to appeal this decision by contacting ijeei.iaes@gmail.com.-----------------------------------------------------------------------Industrial Static Var Generator (SVG) is typically applied at or near the load center to mitigate voltage fluctuation, flicker, phase unbalance, non-sine distortion or other load-related disturbance. Special attention is paid to the influence of grid harmonic on SVG current, the harmonic grid voltage causes not only the AC current distortion but also the DC voltage fluctuation. The harmonic voltage decomposition algorithm and DC voltage control are also introduced. All these analyses can guide the practical applications. The simulation results verify the feasibility and effectiveness of the present control strategy and analyses.

Abstract

In order to make the electronic design contest and reform of experiment teaching to support and promote each other and improve students' practical and innovative ability, the paper analyzed the requirements on the students' ability of comprehensive knowledge application and practice by NUEDC, and the deficiencies of the depth and scope of electronic information professional practice curriculum. Use the issues-based, project-based and case-based engineering education philosophy and teaching methods as orientation. The way of practice teaching reform and the effect of the reform from six aspects are also discussed: the construction of hierarchy practice teaching system, the seminar and the optimizing of teaching content, the engineering teaching method, the experimental teaching environment and full control of network-assisted teaching platform. DOI: http://dx.doi.org/10.11591/telkomnika.v11i8.3144

Abstract

Industrial Static Var Generator (SVG) is typically applied at or near the load center to mitigate voltage fluctuation, flicker, phase unbalance, non-sine distortion or other load-related disturbance. Special attention is paid to the influence of grid voltage quality on SVG current, the non-sine distortion and unbalance of grid voltage causes not only the AC current distortion and unbalance but also the DC voltage fluctuation. In order to let the inverter voltage contain the fundamental negative sequence and harmonic component corresponding to the grid voltage, a new dual-loop control scheme is proposed to suppress the influence in this paper. The harmonic and negative sequence voltage decomposition algorithm and DC voltage control are also introduced. All these analyses can guide the practical applications. The simulation results verify the feasibility and effectiveness of the present control strategy and analyses.
