| 摘要: |
| 针对串并联电能质量补偿装置联合运行时潜在的谐波交互影响问题，以串联电压型补偿装置DVR、并联电流型补偿装置APF为例，分析延迟效应的非线性因素对电网残余谐波电流的影响。构建基于DVR与APF联合运行的简化等效阻抗模型，分析潜在并联谐振问题，并给出解决方案。针对常态化重要负荷的谐波补偿问题，对比分析单台式、阵列式APF等两类运行模式的特点及适用场合。针对模块化APF阵列运行损耗问题，提出了基于等损耗微增率补偿策略的集中控制模式，并开展了APF阵列的工程应用案例分析。 |

| Abstract: |
| The paper looks at the harmonic interaction between series and parallel power quality conditioner compensation. The voltage power quality conditioner DVR and parallel APF are taken as examples, and an analysis is carried out on the harmonic effect caused by the nonlinear nature of delayed effects. Simplified equivalent impedance models based on DVR and APF are built, potential parallel resonance is analyzed, and several solutions are presented. For the harmonic compensation of normal important loads, the features and suitable occasions of single/array APF are also analyzed and compared. For the operating losses of array APF, a centralized control mode based on the equal loss incremental rate compensation strategy is proposed, and then an engineering study related to array APF is carried out.
