Abstract

Charger baterai dapat menurunkan power factor (PF) karena menimbulkan peningkatan tegangan dan arus harmonik. Baterai EV yang habis juga dapat ditukarkan dengan baterai penuh di EV Battery Swap Station. Battery Swap Station memiliki 10 slot baterai yang digunakan untuk mengisi daya baterai dengan kapasitas 72 V 20 Ah secara bersamaan. Penurunan power factor pada EV Battery Swap Station mencapai 0,66, yang masih berada di bawah standar PLN, yaitu 0,85. Penyebab penurunan power factor disebabkan oleh penggunaan charger baterai yang memiliki gelombang non-sinusoidal sehingga dapat meningkatkan harmonik pada gelombang arus. Peningkatan harmonik juga menyebabkan distorsi bentuk gelombang tegangan. Batas nilai Individual Harmonic Distortion (IHD) dan Total Harmonic Distortion (THD) diatur dalam standar IEEE 519-2014. Pengujian pada EV Battery Swap Station dengan 5 charger baterai menimbulkan nilai IHDi dan THDi yang tidak sesuai dengan standar IEEE 519-2014, yaitu IHDi pada orde ke-3, 5, 7, dan 11\. Maka dari itu, diperlukan upaya untuk meningkatkan power factor agar sesuai dengan standar PLN menggunakan capacitor bank dan single tuned passive filter. Pada Tugas Akhir ini akan dirancang implementasi single tuned passive filter dan capacitor bank sebagai upaya perbaikan dan mempertahankan PF mendekati satu (unity) untuk memaksimalkan penggunaan listrik serta meningkatkan PQ pada EV Battery Charging Station. EV Battery Charging Station yang digunakan berupa sistem pengisian daya hanya untuk 1 charger baterai yang langsung terhubung ke baterai EV dengan kapasitas 72 V 20 Ah. Pengujian dilakukan dengan menggunakan beban 1 charger EV battery dengan kapasitas baterai kendaraan listrik sebesar 72 V 20 Ah dan 12 V 20 Ah, baik dengan maupun tanpa penggunaan capacitor bank dan single tuned passive filter. Hasil pengujian menunjukkan bahwa nilai power factor turun dari 0,96 menjadi 0,03 pada pengujian dengan baterai berkapasitas 12 V 20 Ah, sedangkan pada pengujian dengan baterai berkapasitas 72 V 20 Ah, nilai power factor turun dari 0,85 menjadi 0,03 yang disebabkan oleh peningkatan daya reaktif pada sistem.

EV Battery Charging Station has non-linear electronic equipment, namely a battery charger, that can reduce the power factor (PF) because it causes an increase in voltage and harmonic current. A depleted EV battery can be exchanged for a fully charged battery at an EV Battery Swap Station. The Battery Swap Station has ten battery slots that can be used simultaneously to charge 72 V 20 Ah batteries. The power factor at the EV Battery Swap Station decreased to 0.66, which is below the PLN standard of 0.85. The decrease in power factor is caused by the use of a battery charger with a non-sinusoidal waveform, which can increase harmonics in the current waveform. The increase in harmonics also causes distortion of the voltage waveform. The limits for Individual Harmonic Distortion (IHD) and Total Harmonic Distortion (THD) are set by the IEEE 519-2014 standard. Tests on the EV Battery Swap Station with five battery chargers resulted in IHDi and THDi values that did not comply with the IEEE 519-2014 standard, namely IHDi at the 3rd, 5th, 7th, and 11th orders. Therefore, corrective measures are needed to increase the power factor to comply with PLN standards by using a capacitor bank and a single-tuned passive filter. In this final project, the implementation of a single-tuned passive filter and capacitor bank will be designed as an effort to improve and maintain the PF close to one (unity) to maximize electricity utilization and improve PQ at the EV Battery Charging Station. The EV Battery Charging Station used in this study is a charging system for a single battery charger that is directly connected to an EV battery with a capacity of 72 V 20 Ah. The test was conducted using a single EV battery charger with electric vehicle battery capacities of 72 V 20 Ah and 12 V 20 Ah, both with and without the use of a capacitor bank and a single-tuned passive filter. The results showed that the power factor decreased from 0.96 to 0.03 in the test with a 12 V 20 Ah battery, while in the test with a 72 V 20 Ah battery, the power factor decreased from 0.85 to 0.03 due to an increase in the system's reactive power.
