ABSTRAK

Penggunaan capacitor bank dalam upaya meningkatkan faktor daya dalam masalah power quality memiliki beberapa masalah yang harus diperhatikan. Switching capacitor bank saat energization dapat menyebabkan lonjakan transien yang berhubungan dengan tegangan dan arus transien. Tugas akhir ini membahas mengenai simulasi dan analisa tegangan lebih transien akibat adanya switching capacitor bank yang terjadi pada PT. Asahimas Flat Glass Tbk. Unit A1 A2 dengan menggunakan software MATLAB Simulink 7.8. Pengaruh keadaan transient saat switching capasitor bank dapat memberikan dampak yang merugikan baik untuk peralatan maupun sistem secara keseluruhan. Penggunaan Synchronous Closing Breaker sebagai salah satu solusi untuk mengatasi masalah ini. Dengan menggunakan Synchronous Closing Breaker dapat mengurangi tegangan lebih pada keadaan transient dan meredam osilasi yang terjadi. Berdasarkan hasil simulasi nilai tegangan transien yang dihasilkan pada bus 3kV mencapai 2.83 pu dan penggunaan metode Synchronous Closing Breaker dapat mereduksi tegangan transien tersebut hingga 1.52 pu dan mengurangi osilasi transien yang dihasilkan. Selain itu juga dapat mengurangi arus transien.


ABSTRACT

The using of capacitor bank to improve power factor in power quality has few problem to attention. During energization in capacitor bank switching will generate surge transient related with voltage and current transient. This final project considering about simulation and analyze transient overvoltage due to capacitor bank switching that happened at PT. Asahimas Flat Glass Tbk. Unit A1 A2 using MATLAB Simulink 7.8. The transient state impact while switching capacitor occur can damage to instrument and overall system. The using synchronous closing breaker as one solution overcome this problem. By using synchronous Closing Breaker can reduce transient overvoltage. From the result of the simulation shows transient overvoltage on load bus generated 2.83 pu and synchronous closing breaker method can reduce voltage until 1.52 pu and also can reduce transient current and transient oscillation generated.
