PEMODELAN DAN SIMULASI SISTEM PEMBANGKIT TURBIN GAS PLTGU TANJUNG PRIOK
Abstrak: Makalah ini
menyajikan pemodelan dan simulasi sistem pembangkit turbin gas PLTGU Tanjung
Priok. Pemodelan dilakukan dengan pendekatan sistem turbin uap. Model yang
dikembangkan hanya menerima perubahan beban sebagai input pada sistem.Untuk
pengendalian frekuensi sistem dicoba tiga jenis sistem kendali; speed-droopgovernor,
speed-droop governor dengan kendali integral, dan speed-droop governor dengan
dengan kendali integral dan derivatif. Hasil simulasi menunjukkan, saat terjadiperubahan
beban, kendali speed-droop governor dengan kendali integral dan derivatifmampu
mengembalikan frekuensi sistem ke 50 Hz tanpa osilasi . Abstract. This paper
presents the modeling and simulation of the gas turbine generating system of
Tanjung Priok Combined Cycle Power Plant. The gas turbine model isapproximated
using steam turbine systems. The model developed only accepts load changes as
input to the system. Three types of control systems; speed-droop governor, speed-droop
governor with integral control, and speed-droop governor with integral and derivative
control have been tried to control the frequency of the system. The simulationresults
show that, in the presence of load changes, the speed-droop governor with
integraland derivative control is able to bring back the system frequency to 50
Hz withoutoscillation.
