| 摘要: |
| 研制了一套适用于企业配电网低压大电流负荷的谐波与无功补偿装备，即HAPF-IVC综合补偿装置。采用高压与低压相结合的谐波治理方式，在变压器10 kV高压侧采用较小容量的高压注入式混合型有源电力滤波系统（HAPF），同时在380 V低压侧投运一组智能型无功补偿装置（IVC）与无源滤波器相配合以实现无功的动态补偿，达到了谐波治理和无功补偿相结合的效果，解决了大电流情况下HAPF容量限制的瓶颈。实验结果表明输入电流畸变率由补偿前的31.1 % 降低到3.9 %，功率因数由补偿前的0.7提高到0.95。 |

| Abstract: |
| An HAPF-IVC（Hybrid Active Power Filter-Intelligent Var Compensator） equipment is developed for enterprise distribution network with low-voltage high-current load，which applies the harmonic control strategy combining high and low voltages. A small-capacity high-voltage injection-type HAPF is applied at 10 kV side of transformer and a group of IVC equipment is employed with passive filter at 380 V side to realize dynamic reactive power compensation，which realizes both harmonic control and reactive Power compensation，and breaks the capacity limitation of HAPF with high-current load. Experimental results show that，the distortion rate of input current is reduced from 31.1 % to 3.9 % and power factor is improved from 0.7 to 0.95. |
