“…Harmonisa muncul akibat dari aktivitas komponen switching dari VSD. Aktivitas switching tersebut kemudian menghasilkan frekuensi kelipatan 50 Hz atau kelipatan dari frekuensi fundamental yang masuk ke dalam grid PLN [2][3]. Kondisi ini tentu sangat merugikan karena menyebabkan permasalahan teknis seperti kabel cepat panas karena impedansi kabel yang semakin tinggi, turunnya efisiensi peralatan karena losses pada peralatan yang sangat besar, mengurangi life time peralatan listrik, kesalahan pembacaan alat ukur akibat harmonisa yang ikut terukur ke dalam alat ukur sehingga bukan nilai tegangan atau arus fundamental saja namun termasuk tegangan dan arus gangguan harmonisa serta bahkan kebakaran akibat panas berlebih.…”

RTG (Rubber Tyred Gantry) Crane tends to have harmonic distortions. It is caused by the VSD switching process that converts current from DC to AC, decreasing the power quality and affecting power generation. Disturbance tends to happen on voltage or a current sine wave of the system that contains multiplied frequency from fundamental frequency. It is required to analyze based on the IEEE standard of Std 519-2014 which described that the 20kV bus voltage has a limit value of 3% for VIHD and 5% for VTHD. By using available software, simulation is applied to the RTG Crane electrical system. Harmonic distortion will be discussed by gathering simulation result data in the form of the harmonic spectrum and harmonic wave. harmonic filter to be applied is an Active Filter and Passive Filter that then compared the compatibility to solve the harmonic distortion. The analysis is also applied to Power Factor (PF) value changes before and after filter installation.

Smart Grid System has Harmonics Distortions. Caused when switching inverters convert DC current into AC that lowers power quality and affects power generation system. Interference occurs in sinusoidal wavelengths of voltage or system currents that have frequency multiples of fundamental frequencies. Therefore, analysis is required based on IEEE Std 519-2014 standard which is for 20kV Bus voltage has a limit value of 3% for VIHD and 5% for VTHD, using ETAP software was conducted simulating the condition of the non-grid bus system has a VTHD value of 4.9%, while the on-grid system conditions that have inverters for buses have a VTHD value of 5.81%, and simulations before passive filters are installed in the 5th order (f = 250 Hz) with a VTHD value of 6.33%; VIHD 4.82% after installing passive filter VTHD value 1.88 %; VIHD 0.00 %, while in the 7th order (f=350 Hz) the VTHD value is 6.33%; VIHD3.33 % after installing passive filter VTHD value 1.88%; VIHD 0.00%. The passive filter used is a single tuned passive filter. Change the PF (Power Factor) value before filtering is installed on the distribution bus = 82.9%, after the passive filter installed is 88.1%.
