Pemodelan Komponen HVDC Dan Analisa Aliran Daya Pada Sistem Terintegrasi AC-DC Dengan Metoda Sequential Approach

Abstract

In a circumstance where two or more power systems are splitted up by the system frequency discrepancy or the geographical reasons become a must, the application of HVDC will be a considerable choice. In this paper, the modeling of DC transmission line components and the power flow analysis in an integrated AC-DC system will be discussed. The DC lines variables applied in the simulation are DC voltage at converter terminal, converter transformer tap ratio, rectifier firing angle, and current flowing in HVDC line. The use of sequential approach method based on fast decouple, allowing us to do the power flow analysis in AC-DC integrated system without an obligation to re-modify the AC power flow algorithm. Flow chart, the test and outcome, where in this method are using IEE test system will be incorporated in this paper.
