Abstract
Pada Perusahaan PT. Vale Indonesia, ada 3 (tiga) lokasi pembangkit listrik tenaga air yang berada pada satu daerah aliran sungai. Adapun sumber air berasal dari tiga danau yang ada di sekitar wilayah operasional. Pembangkit listrik tenaga air (PLTA) memiliki peran utama untuk menghasilkan Nikel. Oleh karenanya pembangkit listrik tenaga air harus memiliki kehandalan yang tinggi dan umur peralatan yang panjang. Sehingga pemeriksaan secara berkala diperlukan. Makalah ini membahas tentang hasil studi mengenai strategi mengoperasikan dam PLTA dalam rangka untuk mengoptimalkan pengaturan air saat pelaksanaan preventive maintenance, dengan mempertimbangkan permintaan daya listrik pada Furnace peleburan Nikel dan daya pendukung. Linier program dipergunakan sebagai sebuah metode untuk melakukan optimasi. Dari hasil optimasi diperoleh keuntunggan daya listrik yang dihasilkan adalah 24120 MWh dengan flow rate air sebesar 24149.07 m3/detik untuk operasi PLTA tahun 2015.
================================================================================================
PT. Vale Indonesia has three hydropower plants (called PLTA). They have three dams cascaded in one river. The water sources from three lakes at around company operational area. The hydropower plants are main supporting units for Nickel production. Thus the hydropower plants must be have high performance and long live time. Here the preventive maintenance is needed. This paper discusses about study result of dam operating strategy of the hydropower plants in order to optimal water management during preventive maintenance period, by considering of power demand at the smelting furnace and the auxiliary power. Linear programming is used as an optimization method. It is proved that the electric energy of 24120 MWhours be obtained through water flow rate of 24149.07 m3/seconds, for 2015’s operation.
