Abstract

Seiring dengan perkembangan dan penggunaan teknologi elektronika daya yang semakin pesat, serta bermanfaat 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 menghasilkan 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 standar IEEE Std 519-2014 tentang regulasi batas harmonisa. Penggunaan lampu jenis LHE dan LED secara bersamaan akan mengurangi nilai THD arus yang dihasilkan sebesar 3% hingga 9%. Kata kunci : Beban Non Linier, Kualitas Daya Listrik, Harmonisa, Total Harmonic Distortion (THD), IEEE Std 519-2014 tentang regulasi batas harmonisa/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%. Keywords : Non-linier load, Electrical Power Quality, Harmonics, Total Harmonic Distortion (THD), IEEE Std 519-2014 concerning regulation of harmonic distortion limits
