摘要
在分析载波移相正弦脉宽调制(SPWM)与空间矢量脉宽调制(SVPWM)的基础上,提出载波移相SVPWM算法。通过仿真证明了该算法不仅能实现传统载波移相SPWM的调制效果,且具有直流母线电压利用率高、电流调节能力强等特点。搭建了一套静止同步补偿器(STATCOM)样机,将载波移相SVPWM算法运用至其中,给出了控制策略,现场运行结果表明采用该算法的级联STATCOM具备良好的无功补偿与谐波抑制效果。
Based on the analyses of carrier phase-shifted sinusoidal pulse width modulation （SPWM） and space vector pulse width modulation（SVPWM）,the cartier phase-shifted SVPWM is proposed.Simulation result shows compared with the traditional carrier phase-shifted SPWM, the carder phase-shifted SVPWM can not only realize the same effect, but also has a higher DC voltage utilization rate and better current regulation capability.Experimental results indicate the cascaded static synchronous compensator（STATCOM） based on carrier phase-shifted SVPWM has a good compensa- tion of reactive power and harmonics elimination effect.
