摘要准确有效地测量交流侧谐波电压是确保高压直流输电系统安全运行和验证交流侧滤波器设计有效性的重要依据。首先提出一种基于交流侧滤波器的高压直流输电系统谐波电压的测量方法,通过测量流过交流侧滤波器的电流并进行谐波分解,结合滤波器已知的阻抗-频率特性即可准确方便地计算得到交流侧的谐波电压。着重分析滤波器参数失谐时对谐波电压测量结果的影响,针对双调谐滤波器推导了谐波电压测量误差与元件参数失谐度关系的理论表达式,分析失谐程度对各次谐波电压测量的影响,进行谐波电压测量误差相对滤波器元件参数灵敏度的分析,最后通过仿真计算和物理实验验证所提出方法和分析结论的正确性和有效性。

Abstract：Measurement accuracy of AC harmonic voltage is important to ensure the operation safty of high voltage DC (HVDC) system and to validate the effectiveness of the AC filter design. This paper proposes a novel method to measure the harmonic voltage on AC side of HVDC system. The principle is measuring the current of the AC filter, and calculating the harmonic voltage on AC side according to the harmonic analysis from the measured current and the given impendence-frequency characteristic of the filter. The effects of AC filter component detuning on the measurement of harmonic voltage are studied in detail. The theoretical expressions for a double-tuning AC filter are deduced, to describe the relationship between the measurement error of harmonic voltage and the detuning degree of the filter parameters. The influence of detuning degree on the measurement of individual harmonic voltage is also analyzed. The relative sensitivities of the harmonic voltage measurement error to the filter component parameters are studied. Finally, the proposed method is verified by the simulation and lab test.
