| 摘 要： | IEEE Std.1547规定并网逆变器需要具备孤岛运行的能力以维持负载电压稳定。分析了比例积分控制、比例谐振控制和比例复数积分控制3种线性电压控制策略从系统跟随特性、抗扰特性以及系统主导极点分布对3种电压控制方案的稳态特性和动态特性进行了对比,并在Matlab/Simulink中进行了仿真研究。最后在TMS320F2812数字信号处理器数字化控制平台上验证了理论分析的正确性。

| Abstract: | It is specified in IEEE Std.1547 that the grid-connected inverters have to possess the ability of islanded operation to make the load voltage stable.Three kinds of linear voltage control strategies,i.e.,the proportional-integral(PI) control,the proportional-resonant(PR) control and proportional complex integral(PCI) control,are analyzed.The steady state performances and transient performances of the three voltage control strategies are comprehensively compared in system following characteristics,the disturb... |
