Abstract

Turbin Gas Generator merupakan salah satu power plant yang ada di PT. Petrokimia-Gresik, yang digunakan untuk memenuhi kekurang listrik dari PLN untuk kegiatan di pabrik 1 dan juga perumahan di PT.Petrokimia-Gresik. Oleh karena itu perubahan beban sering terjadi. Untuk menjaga performa dari turbin gas, peralatan dalam sistem turbin gas harus dijaga kondisinya agar dapat bekerja secara optimal. Pada Tugas Akhir ini akan dilakukan perhitungan efisiensi sistem turbin gas terhadap beban operasi di GTG PT. Petrokimia-Gresik. Dari hasil perhitungan didapatkan efisiensi tertinggi pada pembebanan 22,61 MW dengan efisiensi siklus 31,79 % Kata Kunci : Turbin Gas, Efisiensi , variasi beban ============================================================================================== Gas turbine generator is one of the existing power plant in PT. Petrokimia-Gresik, which is used to meet the shortage of electricity from PLN for activites in Factory 1 and housing in PT. Petrokimia-Gresik. Therefore load changes is inevitable. To maintain the performance of gas turbine, equipments in gas turbine system must be kept in a proper condition in order to work optimally. In this final project, the efficiency of gas turbine system to operating load in GTG PT. Petrokimia-Gresik will be calculated. From the calculation results, the highest efficiency which is 31,79% is obtained from the load of 22,61 MW. Keywords: Gas Turbine, Efficiency, load variation
