Design Of Three-level SVG Based On SVPWM

A three-level structure Static Var Generator (SVG) based on Space-vectorPulse Width Modulation is designed in this paper, The theory of SVG andSVPWM is studied and analyzed deeply.In theory part, through analyzing the controlling principle ofconventional Space-vector PWM and its disadvantages, this dissertationpresents an improved two-level SVPWM method. Combined with three-levelSVG, in this paper, the usage of three-level SVPWM control strategy onSVG is proposed.Three-level SVG based on Space-vector Pulse Width Modulation is givento the overall design process, on the various aspects of detail;The software simulation has been done with SIMPLORER 7.0, and thesimulation results shows that the use of this control method of SVG betterrealize the reactive power compensation purposes;Completed the hardware part of SVG on the whole, given the variousparts of the detailed circuit diagrams; Designed the software part of thewhole, based on TI's TMS320F2812 DSP programming, given a detailedsoftware design flow, and should pay attention to the issues; The variousmodules have conducted experiments and the system tests.
