Abstract

Abstract. Along with the rapid development of power electronics technology which is also useful for saving electrical energy. This technology is also used in lighting such as energy saving lamps (LHE) and light-emitting diode (LED). However, LHE and LED are non-linear loads that cause electrical power quality problems, namely producing voltage and current waveforms that are no longer sinusoidal or distorted waveforms. Distorted waves cause harmonic waves which have a frequency multiple of the fundamental frequency. The sum of the effective values of the harmonic components of the distorted waveform is calculated in terms of total harmonic distortion (THD). This study found that the THD value of the voltage generated by the LHE and LED loads was equal is 0.80% -1.3%, while the current THD generated by the LHE load was 68.57% - 78.68% and the LED was 72, 15% - 86.04%. The current THD value generated by the LHE and LED loads does not fulfil the IEEE Std 519-2014 harmornic distortion limits. The use of LHE and LED lamps simultaneously will reduce the resulting current THD value by 3% to 9%.

测量节能灯（LHE）和发光二极管（LED）的总谐波失真（THD）

摘要。随着电力电子技术的飞速发展，电力电子技术在节约电能方面也发挥着重要作用。这项技术也用于照明，如节能灯(LHE)和发光二极管(LED)。然而，LHE和LED是非线性负载，会导致电能质量问题，即产生不再是正弦或畸变波形的电压和电流波形。畸变波产生的谐波的频率是基频的几倍。畸变波形中各谐波分量有效值的总和用总谐波失真(THD)来计算。本研究发现LHE与LED负载产生的电压THD值相等，为0.80% -1.3%，而LHE负载产生的电流THD值为68.57% - 78.68%，LED产生的电流THD值为72,15% - 86.04%。LHE和LED负载产生的当前THD值不符合IEEE标准519-2014谐波失真限制。同时使用LHE和LED灯将使产生的电流THD值降低3%至9%。
