Abstrak

Kebutuhan tenaga listrik di Indonesia terus meningkat sesuai dengan laju pertumbuhan ekonomi dan industri serta pertambahan penduduk. Energi listrik merupakan bentuk energi yang sangat umum digunakan bagi masyarakat secara luas. Dalam proses penyaluran energi listrik sering terjadi kasus ketidakseimbangan dan ini tidak dapat diabaikan. Ketidakseimbangan terjadi diakibatkan oleh beban yang tidak seimbang, jalur transmisi yang tidak ditransposisi menghasilkan impedansi yang tidak simetris. Oleh karena itu, perlu dilakukan analisis terhadap ketidakseimbangan yang terjadi pada sistem tenaga dengan cara mengembangkan bentuk pemodelan aliran daya tiga fasa yang dikombinasikan dari persamaan Carson Method, Newton Raphson Method dan komponen simetris sebagai suatu metode yang diusulkan dalam skripsi ini. Dari hasil penelitian yang telah dilakukan, perbedaan yang dihasilkan antara metode aliran daya tiga fasa yang diusulkan mendekati output yang dihasilkan pada software komersil pembanding Digsilent PowerFactory 14.0.520, baik pada keadaan beban yang seimbang maupun beban tidak seimbang. Kata kunci : Carson Method, , Newton Raphson Method, Komponen Simetris Ketidakseimbangan. (Electricity needs in Indonesia continues to increase along with the economic and industrial growth and population growth also. Electrical energy is a form of energy which is very commonly used by the community. In the process of distribution of electrical energy sometimes a case of imbalance occurs, and this cannot be ignored. Imbalance occurs due to an unbalanced load, untransposed transmission lines generate non-symmetrical impedance. Therefore, it is necessary to analyze the unbalance that occurs in the power systems by developing a form of three-phase power flow modeling which is combined by the equations of Carson Method, Newton Raphson Method and symmetrical components as a method that is proposed in this paper. From the research that has been done, the result between the three-phase power flow method approach produced output to commercial software Digsilent Power Factory 14.0.520, as a comparison software, both on the state of balanced load or unbalanced load. Keywords: Carson Method, Symmetrical Components, Newton Raphson Method,Unbalanced.)
