| 摘要: |
| 新型并联电抗式混合有源电力滤波器（PITHAPF）的耦合变压器两端并联了一个附加电感，它为基波无功电流提供通路，有源部分不承受基波电压，因而更适用于高压系统的动态谐波治理和大容量的无功补偿。从理论上分析了PITHAPF的复合控制策略，定义了负载谐波电流影响因子和电网谐波电压影响因子。仿真结果和实验结果证明了当电网谐波电流的控制参数取负虚数且负载谐波电流的控制参数取1时，PITHAPF具有很好的谐波补偿和谐振抑制特性。 |

| Abstract: |
| PITHAPF（Parallel Inductor Type Hybrid Active Power Filter） has an additional inductor connecting in parallel with its coupling transformer to provide the path for fundamental reactive current. As its active part does not bear the fundamental voltage，PITHAPF is more suitable for the dynamic harmonic suppression of high-voltage system and the large capacity reactive compensation. Its composite control strategy is analyzed，and the influencing factor of load harmonic current and the influencing factor of grid harmonic voltage are defined. The simulative and experimental results confirm that，PITHAPF has excellent performance in harmonic compensation and resonant inhibition when the control parameter of grid-side harmonic current is a negative imaginary number and the control parameter of load-side harmonic current is 1. |
