ABSTRAK

Penyebaran harmonisa dalam suatu sistem distribusi tenaga listrik dapat menimbulkan rugi-rugi dalam penyaluran energi listrik dan juga menyebabkan kerusakan pada peralatan listrik. Salah satu penyebab munculnya distorsi harmonisa dalam sistem distribusi adalah beban nonlinier. Dengan meninjau akibat yang ditimbulkan dari penyebaran harmonisa maka diperlukan suatu metode untuk memodelkan sistem distribusi dan menganalisa penyebaran harmonisa dalam sistem sistem distribusi sehingga besar dan lokasi harmonisa dapat diketahui. Metode forward-backward adalah salah satu metode yang dapat digunakan untuk melakukan studi aliran daya harmonisa dalam sistem distribusi khususnya sistem distribusi radial. Metode ini memanfaatkan vektor dalam bentuk matrik untuk mengetahui aliran arus injeksi dalam saluran distribusi dan juga matrik dari impedansi saluran yang digunakan untuk perhitungan tegangan harmonisa di tiap bus. Metode forward-backward dapat digunakan untuk studi aliran daya harmonisa sistem distribusi satu fasa tiga fasa seimbang dan tiga fasa tak seimbang. Dari hasil pengujian sistem distribusi 20 bus tiga fasa tak seimbang dengan software ETAP sebagai pembanding didapatkan nilai error untuk fasa A sebesar 770 untuk fasa B sebesar 572 dan untuk fasa C sebesar 511.


ABSTRACT

As harmonics distortion propagate trough the distribution system it would result in losses increases and possible cause equipment loss of life. The use of nonlinear loads in distribution system is one cause harmonics distortion. Reviewing the effects caused by harmonics distortion then harmonic analysis methods are used to investigate the harmonics propagation in the distribution system. One of the methods that can be used to calculate the harmonics value is forward-backward method the backward sweep is used to build the relationship between branch currents and bus current injections and the forward sweep can use to calculate bus voltage. This method can be used to calculate the harmonics value in single phase and multiphase radial distribution system. From the test system for 20 bus unbalance radial distribution system this method has error value 7.70 for phase A 5.72 for phase B and 6.11 for phase C.
