Abstract

The electrical system of electric railcar with the variable voltage variable frequency (VVVE) technology has been equipped with different devices functioning to change the DC-link voltage from the overhead line in undesired conditions. It also transmits energy powered by the motor due to a braking process not able to be transmitted back to the overhead line, and keeps the DC-link voltage stable during the braking process. The inverter functions to change the DC-link voltage into a source of AC 3 phase whose voltage and frequency can be regulated. The voltage and frequency variables produced are used to power four induction motors. The rotation speed of the motor can be set as desired by regulating the voltage and frequency of the AC source. Another function is to transmit back the force generated by the motor during the braking to the overhead line.

Abstract

Sistem static inverter (SIV) pada KRL Holec-BN dengan teknologi VVVF (variable voltage variable freguency), mengubah tegangan input nominal 1.500 VDC menjadi tegangan output 380 VAC, tiga fasa, 50 Hz serta 110 VDC dan 137 VDC. SIV melayani beban berupa sistem kompresor, ventilasi, lampu-lampu penerangan, kontrol drive/pengereman, dll. Beban/pengguna daya listrik yang dilayani oleh SIV bisa saja berhenti beroperasi pada saat terjadi kondisi darurat. Ini membantu sistem/beban tersebut tetap bekerja jika salah satu STV berhenti dan masih beroperasi Jika kedua SIV mengalami gangguan. Seperti disebutkan di depan, KRL Holec-BN mengoperasikan dua unit SIV pada setiap trainset KRL. Frekuensi gangguan dan kerusakan SIV pada KRL Holec-BN termasuk tinggi. Supaya keandalan KRL ini dapat dipertahankan pada level yang dapat diterima, maka langkah perbaikan diperlukan guna mencegah gangguan dan kerusakan terus berlanjut. Keandalan yang tinggi diperlukan agar ketersediaan KRL juga tinggi sehingga mampu memenuhi harapan masyarakat pengguna jasa dalam memperoleh angkutan perkeretaapian yang aman, selamat, nyaman, andal, tepat waktu, dll.
