| dc.description | Kereta Rel Listrik (KRL) merupakan kereta yang yang bergerak
berdasarkan sistem eletrifikasi. Sistem elektrifasi pada KRL mengalirkan energi
listrik ke lokomotif kereta dan beberapa unit gerbong lainnya sehingga kereta
tersebut dapat berjalan. Energi listrik dapat berupa sumber AC maupun DC.
Terdapat dua sistem kelistrikan yang mendukung kinerja dari KRL, yaitu sistem
propulsi dan sistem auxiliary. Sistem propulsi merupakan sistem penggerak
sementara sistem auxiliary merupakan sistem yang menangani beban kelistrikan
pada KRL.
Pada penelitian kali ini, membahas tentang rugi-rugi sistem propulsi pada
KRL LAA Listrik DC, Motor Traksi AC. Sistem propulsi tersebut terdiri dari
beberapa komponen yaitu pantograf, circuit breaker, tapis kapasitor, inverter
VVVF IGBT dan motor traksi AC. Masing-masing komponen memilki rugi-rugi
yang berbeda sehingga menghasilkan efisiensi yang berbeda.
Terdapat lima kondisi pengujian tegangan input motor traksi AC yaitu
160,5V, 321V, 493,9V, 635V dan 645V. Dengan menghitung menggunakan
persamaan, dari kelima kondisi pengujian tersebut dapat diketahui bahwa sistem
propulsi memiliki rugi-rugi terendah dengan efisiensi tertinggi pada tegangan
input motor traksi AC 635V, dimana diperoleh besarnya rugi-rugi inverter VVVF
IGBT sebesar 41,996kW dengan efisiensi 90,67% dan besarnya rugi-rugi motor
traksi AC sebesar 18,219kW dengan efisiensi 91,45%. | en_US |
| dc.description.abstract | Electric Railway (KRL) is a train that is based on eletrification system.
The electrification system in the KRL supplies electrical energy to the train
locomotive and several other carriage units, so the train can run. Electrical
energy can be either AC or DC source. There are two electrical systems to
support the performance of KRL, propulsion system and auxiliary system. The
propulsion system is a driving system and than the auxiliary system is the system
that handles the electrical load on KRL.
In this research, discuss about the loss of propulsion system on KRL LAA
Electric DC, AC Traction Motor. The propulsion system consists of several
components, such as pantograph, circuit breaker, capacitor filter, IGBT VVVF
inverters and AC traction motors. The component has different losses and
different efficiencies.
There are five test conditions for AC traction voltage inputs of 160.5V,
321V, 493.9V, 635V and 645V. By calculating using equations, from the five test
conditions it can be seen that the propulsion system has the lowest power loss
with the highest efficiency at the input voltage of AC 635V traction motors, which
obtained the power loss of inverter VVVF IGBT 41.996kW with the efficiency
90.67% and the power loss of AC traction motor 18.219kW with the efficiency
91.45%. | en_US |
