| 摘 要： | 为提高有源滤波器的电流跟踪性能,针对传统空间矢量脉宽调制(SVPWM)电流跟踪算法的不足,提出了一种用于并联有源滤波器的SVPWM电流跟踪算法的优化方法。该跟踪算法利用三相相间误差电流的正负来判断空间指令电压矢量所在的区域。与传统SVPWM电流跟踪算法相比,省略了三相电网电压的检测环节,即省略了判断空间指令电压矢量所在区域的复杂运算,从而简化了硬件电路,同时也简化了算法。针对以三相不可控整流阻感负载为谐波源的电路模型,分别采用传统SVPWM电流跟踪算法和所设计的SVPWM电流跟踪算法作为有源滤波器的电流控制方法,进行了滤除谐波电流的实验。

| Abstract: | In order to improve the performance of current tracking algorithm of traditional space vector pulse width modulation(SVPWM),an optimized method for shunt active power filter(APF) is proposed.The optimized current tracking algorithm uses the phase-to-phase current error to decide the district of space instruction voltage vector.Compared with the traditional current tracking algorithm,detection of three-phase network voltage and the complex calculation for deciding the scope of space instruction voltage vector are not needed.This significantly simplifies hardware circuit and its related algorithm design.The two algorithms for current tracking in an APF are validated through a simulation experiment with a circuit model that contains a three-phase uncontrollable rectification RL load. |
