Abstract

Peningkatan beban-beban nonlinier yang terpasang pada sistem akan menyebabkan terjadinya distorsi harmonisa. Distorsi harmonisa pada bentuk gelombang tegangan dan arus dapat mengakibatkan kondisi tidak normal pada sistem. Pada sistem distribusi 3 phasa sering dijumpai kondisi beban yang tak seimbang. Tegangan takseimbang dapat memunculkan komponen urutan negatif dan urutan nol yang merugikan sistem. Komponen urutan negatif akan mengakibatkan peningkatan panas yang berlebihan, sedangkan komponen urutan nol di samping dapat menyebabkan peningkatan rugi-rugi pada jaringan transmisi juga mengakibatkan gangguan pada sistem proteksi dan masalah interference. Metode urutan digunakan untuk menganalisis harmonisa pada kondisi takseimbang. Analisis harmonisa dilakukan untuk mengevaluasi efek distorsi dari bentuk gelombang arus dan tegangan non-sinusoidal pada sistem daya listrik.

An increase in non-linear loads connected to power system results in harmonic distortion. The presence of harmonic distortions in form of voltage and current waveforms may causes abnormality to the system. Unbalanced load usually occurs in three phase distribution systems. The unbalanced voltage produces negative and zero sequence components of the voltage, which cause adverse influence to the system. The presence of the negative sequence component produces excessive heat, while the presence of the zero sequence component results in an increase in the transmission loss, protection failure and interference problems. This thesis discusses the application of the sequence method in analysing harmonics of an unbalanced condition. Harmonic analysis was used to evaluate the effects of distorted current and voltage waveforms on the electrical power systems.
