ANALISIS KONTINGENSI SISTEM TENAGA LISTRIK DENGAN MENGGUNAKAN POWER WORLD SIMULATOR (Aplikasi SUTT 150 kV SumBagTeng)

Abstract

Power system deterministic Contingency analysis represent a power system security analysis by making simulation breaking of line transmission, generating unit and power transformator at one particular the power system, and also see resulted influenced. In this research analyse power system deterministic contingency by using Newton-Raphson load flow method, to analyse normal situation or change of load flow effect of contingency, made as data a power of electric system. So with analyse different comparison of voltage with tolerance 5%, hence got by PI value is 1.28281257185155e-020 until 2. Calculation PI value and Newton-Rapshon load flow to the condition of early and to each every contingency constructively Matlab software. For the simulation of electric power system contingency, used by Simulator Power World. Moment happened release of transmission line at Ombilin bus with Salak bus hence power awakened by PLTU Ombilin channelled to transmission is to Indarung bus, Batu Sangkar and Kiliran Jao equal to 92 MW and experience of system peak load equal to 441.11 MW. So also to the condition shedding of other transmission. To the condition of shedding of generating unit, seen at case shedding of PLTA Maninjau generator, load for the PLTA of Maninjau in taking over by PLTA Singkarak and power supply can equal to 7.5 MVR. Power System application is middle shares sumatera.
