Abstract

Kestabilan sistem tenaga listrik merupakan hal sensitif yang harus di perhatikan. Salah satu jenis kestabilan pada sistem tenaga listrik yaitu kestabilan transien dengan pengamatan kestabilan sudut rotor. Sistem jaringan listrik JAMALI merupakan sistem jaringan listrik multi-machine dengan sistem terinterkoneksi. Dalam melakukan analisis pada sistem multi-machine tersebut diperlukan suatu metode yang lebih sederhana, salah satunya yaitu menggunakan metode Power Flow Tracing (PFT). Hasil dari PFT berupa suatu penyederhanaan sistem multi-machine menjadi sistem Single Machine to Infinite Bus (SMIB). Analisis kestabilan transien dengan sistem SMIB pada tugas akhir ini menggunakan konsep Equal Area Criterion (EAC). Konsep EAC yaitu menentukan sudut kritis rotor dari daya elektrik yang dihasilkan oleh generator. Dari hasi EAC diperoleh nilai sudut kritis dan prediksi waktu pemutusan kritis dengan mengamati beberapa generator. Pada Tugas Akhir ini, dilakukan analisis kestabilan transien akibat gangguan hubung singkat 3 fasa terhadap tanah pada saluran Balaraja-Cikupa. Berdasarkan hasil analisis, dengan menggunakan konsep PFT dengan analisis EAC diperoleh nilai sudut pemutus kritis 94,61010 dengan prediksi time clearing 0,0715 detik. Pada sistem multi-machine dengan nilai 0,07869 detik sistem dalam keadaan stabil kritis, dan untuk waktu pemutus krtis 0,08 detik, sistem tidak stabil. Berdasarkan pada hasil analisis, metode PFT dapat merpresentasikan sistem multi-machine dengan sistem interkoneksi. ================ The stability of the electric power system is a sensitive case. One type of stability in electric power system is transient stability with rotor angle stability observation. JAMALI's electrical grid system is a multi-machine electrical network system with interconnected systems. In analyzing the multi-machine system is needed more simple method, one of them is using Power Flow Tracing method (PFT). The result of PFT is a simplification of multi-machine system into Single Machine to Infinite Bus (SMIB) system. Analysis of transient stability with SMIB system in this final project using Equal Area Criterion (EAC) concept. The EAC concept is to determine the critical angle of the rotor from the electrical power generated by the generator. From EAC results obtained the critical angle value and the prediction of critical clearing time by observing some generators. In this Final Project, the transient stability analysis with case due to the 3 phase fault to ground on Balaraja-Cikupa line. Based on the results of analysis, using the concept of PFT with EAC analysis obtained the value of critical breaker angle 94.61010 with a prediction of 0.0715 seconds clearing time. In a multi-machine system with a value of 0.07869 seconds the system is in a stable critical state, and for a break time of 0.08 seconds crystals, the system is unstable. Based on the results of the analysis, the PFT method can represent a multi-machine system with an interconnect system.
