摘要
随着大量非线性负荷接入电网,其引起的谐波问题也日渐严重。各国家或组织制定了谐波标准约束非线性用户谐波发射值,保证交流电网的波形质量。如何在电力用户间公平合理地分配允许谐波发射值成为核心的关键问题。通过对比分析IEC 61000-3-6、GB/T 14549与IEEE Std.519中非线性负荷接入高压系统谐波发射水平分配方法,以公平性、一致性与可行性3个原则评估各标准适用性,并通过案例结果对比,评估三者一致性,为谐波国家标准修订提供一些参考。
With a large number of nonlinear loads connected to the power grid,the harmonic problems caused by them are becoming more and more serious.Various countries or organizations have formulated harmonic standards to constrain the harmonic emission values of nonlinear users to ensure the waveform quality of the AC power grid.How to distribute the allowable harmonic emission value fairly and reasonably among power users has become a key issue.By comparing and analyzing the harmonic emission level distribution methods of nonlinear load access to high voltage system in IEC 61000-3-6,GB/T 14549 and IEEE Std.519,the applicability of each standard is evaluated by three principles of fairness,consistency and feasibility,and the consistency of the three is evaluated by comparing the case study results,which can provide some references for the revision of harmonic national standards.
