摘要:

GB/T 14549自颁布实施以来,有效监督了电网中的谐波问题,保证了电能质量。随着新型电力系统的发展,电网中的谐波呈现新特征,GB/T 14549难以完全适应当前电网发展与现代管理需求。针对新型电力系统中的谐波特征,基于GB/T 14549的谐波电流允许值分配方法,分别针对总谐波电流约束指标、供电容量取值方法和叠加方法,给出关键参数的取值方法,通过案例验证其合理性与有效性,有效约束了谐波注入,为谐波国家标准修订提供参考。

Abstract:

Since its promulgation and implementation, GB/T 14549 has effectively regulated the harmonic issues in power grids and ensured the power quality. However, with the development of new power systems, the harmonics in power grids have exhibited new characteristics, making GB/T 14549 hardly fully adaptable to the current needs of power grid development and modern management. Therefore, aiming at the harmonic characteristics in new power systems, and based on allocation method for allowable harmonic current values specified in GB/T 14549, this paper focuses on the constraint index for total harmonic current, the selection method for power supply capacity, and the superposition method, respectively, and proposes the selection methods for key parameters. Its rationality and effectiveness are validated through the case studies, which effectively restricts harmonic injection and provides a reference for the revision of the national harmonic standards.

Key words: GB/T 14549, total harmonic current constraint, power supply capacity, harmonic superposition
