摘　　要：电力系统规划和运行中的谐波评估是电网谐波水平管控的关键。为了预防性地控制谐波电压水平,对于大、中型非线性的电网用户接入电网,在电力系统规划中需要按照相关标准及规定进行谐波评估。对实际运行中,也需要对电网谐波电压和用户谐波发射进行评估。进行本文基于我国谐波标准和相关规定以及我国电网发展的实际情况,结合国外相关研究的发展状况,讨论目前电网发展情况下谐波评估面临的挑战,主要包括为谐波电压限值、责任分配、谐波电流限值、测量评估等问题,为我国谐波标准和评估方法的发展提供参考。Harmonic assessment in power system planning and operation is the key to harmonic management and control.When large and medium non-linear devices access to the grid,harmonic assessment in power system planning are carried out according to harmonic standards and relevant regulations,In order to preventively control the harmonic voltage level.During power system operation,harmonic assessment is also necessary to evaluate the harmonic voltage and emission.In this paper,based on the national harmonic standard and relevant regulations and the development of power system in China,combined with relevant development and research abroad,the challenges of harmonic assessment are discussed,including the limits of harmonic voltage,the responsibility allocation among grid side and users,the limits of harmonic current,evaluation method and measurement method etc.It may provide a good reference for the development of harmonics standard and evaluation methods in China.
