低压成套无功补偿装置抑制谐波或滤波功能验证试验研究

Experimental Study on Verification of Harmonic Suppression or Filtering Function of Low-voltage Complete Set Reactive Power Compensation Device

非线性负载的大量使用使电压电流波形产生了畸变,也使电力系统的谐波污染进一步加重。现阶段,一些低压成套无功补偿装置都加入了谐波的治理设备,抑制谐波或滤波功能验证试验是谐波治理设备的一项重要试验。本文通过分析国家标准中对谐波限值及抑制谐波或滤波功能验证试验的相关要求,讨论研究了相关的试验和方法。

As the large use of nonlinear loads,the voltage and current waveforms are distorted,and the harmonic pollution of power system is further aggravated.At present,some low-voltage reactive power compensation devices have added to the harmonic control equipment and the verification test of harmonic suppression or filtering function is an important test of the harmonic control equipment.This paper studies the relevant tests and methods by analyzing the related requirements of harmonic limit and verification test of harmonic suppression or filtering function according to the national standards.
