Abstract

PT Indonesia Chemical Alumina ("PT ICA") mengumumkan penunjukan konsorsium WIKA Group sebagai kandidat pertama kontraktor Engineering, Procurement and Construction (EPC) proyek Chemical Grade Alumina (CGA) Tayan. PT ICA merupakan perusahaan patungan antara ANTAM (IDX-ANTM; ASX-ATM), Showa Denko K.K. dan Marubeni Corporation dari Jepang. Sebagai perusahaan yang memproduksi 300.000 ton CGA per tahun. yang akan mengalami pengembangan sistem, tentu memerlukan analisa stabilitas transient supaya dapat menjaga kelangsungan plant yang akan dikembangkan sehingga dapat terus beroperasi tanpa terkendala gangguan pada sistem kelistrikan, agar selalu stabil pada saat produksi sebab apabila proses produksi terganggu oleh suplai listrik yang tidak setabil. Tugas akhir ini menganalisa kestabilan transien dan mekanisme pelepasan beban yang terdapat pada PT Indonesia Chemical Alumina ("PT ICA") sehingga dapat diperoleh keandalan dan kontinuitas yang layak. Pada tugas akhir ini analisis yang dilakukan meliputi kestabilan transien dan mekanisme pelepasan beban akibat generator outage(off), Short Circuit dan Motor Starting. Hasil simulasi menujukan bahwa lepasnya 1 generator ketika 1 generator ON memerlukan Load Shedding. Dalam kasus hubung singkat di salah satu bus, tegangan sistem turun hingga mencapai kondisi terendah sehingga diperlukan pengisolasian gangguan melalui pembukaan CB pada sumber gangguan selain itu kasus motor starting masih diperbolehkan pada saat 2 Generator ON ======================================================================================================== PT Indonesia Chemical Alumina ("PT ICA") announces the appointment of a consortium of WIKA Group as the first candidate Engineering, Procurement and Construction (EPC) projects Chemical Grade Alumina (CGA) project. PT ICA is a joint venture between ANTAM (IDX-ANTM; ASX-ATM), Showa Denko KK and Marubeni Corporation of Japan. As a company that produces 300,000 tons per year CGA. which will experience the development of the system, would require transient stability analysis in order to sustain the plant to be developed so that it can continue to operate without disruption constrained the electrical system, so that always stable at the time of production because if the production process is interrupted by a power supply that does not setabil it will undergo loss very large. The final task is to analyze the stability and transient load release mechanisms on PT Indonesia Chemical Alumina ("PT ICA") so as to obtain the reliability and continuity it deserves. In this final analysis was conducted on the stability of the transient and load release mechanisms due to a generator outage (off), Short Circuit and Motor Starting. Addressing the simulation results that the loss of one generator when one generator ON requires Load Shedding. In the case of short circuit in one of the buses, the system voltage drops until it reaches its lowest condition requiring isolation of interference through the opening of the CB on the source of interference other than that the case was still May the Motor strating at the time of 2 Generator ON
