摘要随着智能电网的发展和新能源并网发电容量的扩大,电网中电力电子装置的数量不断增加,使得电网谐波呈现出宽频域特征。谐波频域范围的扩大使得远距离高压输电线路中的分布电容对谐波问题的影响愈加明显。本文首先建立考虑分布电容影响的宽频域输电线路模型,在此基础上对谐波谐振劣化问题的内在机理进行研究。通过对实际线路的理论分析和实测结果比较,验证了本文所提谐振劣化分析方法的正确性。结合理论分析和实证结果,对国标（GB）和国际电工委员会（IEC）标准进行比较,发现现有标准无法完全涵盖具有新特点的谐波问题,本文可为标准优化提供理论参考依据。

Abstract：With the development of smart grid and new energy generation, the number of power electronic devices in power grid is constantly increasing, which makes the harmonic characteristics of power grid become wide-band. The harmonics will be boosted by the distribution capacitance in long distance HV transmission lines, and lead to a serious harmonic problem. In this paper, a wide-band frequency transmission line model considering the influence of distributed capacitance is established, and the internal mechanism of harmonic resonance degradation is studied. Through theoretical analysis and measurement for an actual line, the correctness of the resonance deterioration analysis method which proposed in this paper is verified. A comparative study is made between the GB and the international electrotechnical commission (IEC) standard. It is found that the existing standards cannot fully cover the harmonic problems with new characteristics. This paper can provide a theoretical reference for standard optimization.

Key words： Power quality wide-band frequency harmonics harmonic resonance harmonic standard
