ElectricalAutomation自动化装置与设备AutomationDevices＆Equipments《电气自动化》2023年第45卷第1期基于三相维也纳整流器的变基本空间矢量控制王冬冬，孙玉坤(南京工程学院电力工程学院，江苏南京211167)摘要:针对采用定基本空间矢量－空间矢量脉宽调制控制的三相维也纳(Vienna)整流器在抑制直流侧电压波动方面存在缺陷的问题，提出一种变基本空间矢量－空间矢量脉宽调制(variablebasicspacevector-spacevectorpulsewidthmodulation，VBSV-SVP-WM)控制。将直流侧实时电压反馈回控制电路，构成VBSV-SVPWM控制，使得系统对于直流侧电压波动有着更好的响应性能。在MATLAB/Simulink中搭建仿真模型，验证所述理论的正确性。试验结果表明，采用VBSV-SVPWM控制策略的三相Vi-enna整流器有着良好的运行性能，对直流侧电压波动有着更强的抑制能力。关键词:三相维也纳整流器;变基本空间矢量;空间矢量脉宽调制;电压反馈;电压波动抑制DOI:10．3969/j．issn．1000－3886．2023．01．026［中图分类号］TM461［文献标志码］A［文章编号］1000－3886(2023)01－0089－04VariableBasicSpaceVectorControlBasedonThree-phaseViennaＲectifierWangDongdong，SunYukun(SchoolofElectricalPowerEngineering，NanjingInstituteofTechnology，NanjingJiangsu211167，China)Abstract:Aimingatthedefectsofthree-phaseViennarectifiercontrolledbyfixedbasicspacevectorspacer-spacevectorpulsewidthmodulationinsuppressingDCsidevoltagefluctuation，avariablebasicspacevector-spacevectorpulsewidthmodulation(VBSV-SVPWM)controlwasproposed．Thereal-timevoltageontheDCsidewasfedbacktothecontrolcircuittoformVBSV-SVPWMcontrol，whichmadethesystemhadbetterresponseperformancetothevoltagefluctuationontheDCside．ThesimulationmodelwasbuiltinMATLAB/Simulinktoverifythecorrectnessofthetheory．Theexperimentalresultsshowthatthethree-phaseViennarectifierwithVBSV-SVPWMcontrolstrategyhasgoodoperationperformanceandstrongersuppressionabilitytoDCsidevoltagefluctuation．Keywords:three-phaseViennarectifier;variablebasicspacevector(VBSV);spacevectorpulsewidthmodulation(SVPWM);voltagefeedback;voltagefluctuationsuppression定稿日期:2021－11－28基金项目:国家自然科学基金项目(51877101)0引言三相维也纳(Vienna)整流器作为一种主流三电平...
