Abstract

Seiring dengan perkembangan dan penggunaan teknologi elektronika daya dan semakin pesat, yang bermanfaat juga untuk penghematan energi listrik. Perkembangan teknologi elektronika daya tersebut juga dimanfaatkan pada teknologi penerangan seperti, lampu hemat energi (LHE) dan light-emitting diode (LED). Namun, LHE dan LED merupakan beban non-linier yang menimbulkan masalah kualitas daya listrik yaitu bentuk gelombang tegangan dan arus yang tidak sinusoidal lagi. Bentuk gelombang yang tidak sinusoidal atau terdistorsi menyebabkan gelombang harmonisa yang mempunyai frekuensi berkelipatan dari frekuensi dasar. Jumlah nilai efektif komponen harmonik dari bentuk gelombang terdistorsi dihitung dalam besaran total harmonic distortion (THD). Pada penelitian ini diperoleh bahwa, nilai THD tegangan yang dihasilkan oleh beban LHE dan LED sama besar yaitu 0,80 % -1,3 %, sedangkan THD arus dihasilkan beban LHE sebesar 68,57% - 78,68 % dan LED sebesar 72,15 % - 86,04 %. Nilai THD arus yang dihasilkan oleh beban LHE dan LED tidak memenuhi dengan standar batas harmonisa arus oleh IEEE Std 519-2014 tentang regulasi batas harmonisa. Kata kunci : Beban Non Linier, Kualitas Daya Listrik, Harmonisa, Total Harmonic Distortion (THD), IEEE Std 519-2014 tentang regulasi batas harmonisa. / Along with the development and use of power electronics technology and rapidly, which is also useful for saving electrical energy. The development of power electronics technology is also used in lighting technology such as energy-saving lamps (LHE) and light-emitting diodes (LED). However, LHE and LED are non-linear loads that cause power quality problems, namely the voltage and current waveforms that are no longer sinusoidal. Waveforms that are not sinusoidal or distorted cause harmonic waves that have frequencies that are multiples of the fundamental frequency. The effective number of harmonic components of the distorted waveform is calculated in terms of the total harmonic distortion (THD). In this study, it was found that the THD value of the voltage generated by the LHE and LED loads was the same, namely 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 meet the current harmonic limit standard by IEEE Std 519-2014 concerning harmonic limit regulation.
