摘要
针对非线性负载增多导致的用电系统电能质量问题,以及低压用电系统中的电压波形、电流波形发生严重畸变、谐波组成比例增加的状况,提出一种基于瞬时叠加原理的新型低压用电系统谐波治理装置,设计出主电路和控制电路,并通过实验验证,指出该装置在改善电流波形、降低各次分量谐波和谐波畸变率方面具有优越性能,并具有价格低、体积小、便于安装等特点。
In view of the power quality problems caused by the increase of non-linear load, and the serious distortion of voltage waveforms and current waveforms, and the increase of the proportion of harmonic components in the low-voltage power system, a new type of harmonic control device based on instantaneous superposition principle for the low-voltage power system is proposed. The hardware circuit and control circuit are designed. It is proved by experiments that the device has superior performance in improving current waveforms, reducing harmonics of each component and harmonic distortion rate, and has the characteristics of low price, small volume and easy installation.
