中文摘要:

供电网公共连接点处主谐波源的定位,是对谐波污染采取合理抑制措施的重要前提。本文从非正弦条件下功率的分解方法出发,提出一种基于谐波畸变功率的主谐波源定位新方法,实现了适用于IEEE Std. 1459-2010标准的主谐波源定位。通过比较同一系统供电线性与非线性负荷情况下视在功率分量与瞬时功率分量的对应关系,证明了谐波畸变功率对于主谐波源定位的有效性。多种情况下的仿真分析和实侧验证结果证明了本文方法的正确性和合理性。

英文摘要:

The detection of harmonic sources on the point of common coupling (PCC) is the important premise of responsibility proration and harmonic elimination. In this paper,a method of nonlinear load detection based on harmonic distortion power is proposed, which is applicable for the IEEE Std. 1459-2010 standard. By comparing the corresponding relationship between the instantaneous power components and apparent power components of linear and nonlinear load cases, the effectiveness of the proposed method is proved. Multiple cases of simulation analysis and measurement results prove the validity and rationality of this method.
