| 摘 要： | 针对传统三相abc坐标系控制无法清除系统耦合量的扰动,建立了基于三电平SVPWM的无谐波检测环节解耦控制系统.通过对电网电压不平衡时上述无谐被检测有源电力滤波器解耦系统如何控制进行了研究,提出电网电压不平衡时系统控制方案.仿真试验表明,该无谐波检测解耦控制系统动态跟踪速度快、补偿效果好,不受负载突变影响,且当电网电压不平衡时依然能够保证有很好的谐波电流补偿性能.

| Abstract: | The traditional three-phase abc coordinate can not eliminate the disturbance of system coupling amount.Based on it,the dq axis decoupling control system based on three-level SVPWM was establied,and how to control the proposed non-harmonic detection APF decoupling system when the grid voltage is unbalanced was studied,and the system control program was presented.The simulation results show that the non-harmonic detection decoupling control system has high dynamic tracking speed,good compensation effect,without the influence of load mutations,and still has good harmonic compensation performance when the grid voltage is unbalanced. |
