1.1
Prosedur penelitian
Prosedur dalam melakukan penelitian terdiri dalam beberapa langkah, yaitu
langkah pertama melakukan studi literatur dari berbagai sumber terpercaya seperti
jurnal internasional, data teknis perusahaan, laporan teknik perusahaan, dll.
Langkah kedua yaitu setelah mendapatkan data yang cukup mengenai PLTP
Kamojang maka selanjutnya membuat desain SCADA virtual PLTP Kamojang
dari flow diagram yang telah ada di PT. Indonesia Power UBP Kamojang dengan
menggunakan software Wonderware Intouch 10.0. Langkah ketiga, memberikan
tagname kepada masing-masing object di desain SCADA tersebut. Langkah
keempat yaitu membuat animation link pada setiap object agar ketika di run time
akan terlihat hidup sepertii dengan keadaan real dilapangan.
Setelah membuat animation link, langkah kelima membuat sript real time
trend yang menampilkan grafik secara real time. Kemudian langkah keenam
membuat historical trend yang menampilkan grafik peristiwa yang terjadi di masa
lampau dalam waktu tertentu. Langkah ketujuh membuat alarm system yang akan
menunjukan indikasi adanya perubahan keadaan yang tidak aman pada sistem.
Langkah kedelapan membuat security system. Security system bertujuan untuk
menjaga sistem dari kesalahan kerja operator yang tidak sesuai dengan set point
system yang telah dibuat. Langkah selanjutnya yaitu melakukan uji coba pada
system mulai dari historical trend, real time trend, alarm system dan security
system apakah bekerja sesuai yang diinginkan atau tidak. Apabila ada fungsi yang
tidak berkerja, maka kembali ke langkah ketiga yaitu memberi tagname dan
mengikuti langkah selanjutnya hingga sistem bekerja sesuai yang dinginkan.
