VSD umum digunakan sebagai penggerak motor listrik untuk pompa, kompresor atau blower yang banyak digunakan dalam berbagai proses di industri farmasi. Namun perlu diperhatikan bahwa penggunaan VSD dapat membawa dampak buruk terhadap sistem daya listrik di industri bersangkutan. Salah satunya adalah permasalahan kualitas daya berupa munculnya harmonisa pada sistem daya listrik. Berdasarkan data pengukuran lapangan, harmonisa arus pada sistem distribusi daya listrik untuk unit AHU dari sebuah industri farmasi yang dipilih sebagai objek studi masih berada di bawah standar IEEE 519-1992. Nilai total harmonic distortion arus (THDi) yang terukur mencapai kisaran 40% – 50% dengan harmonisa ke-5, ke-7 dan ke-11 merupakan orde-orde harmonisa yang dominan. Simulasi dengan perangkat lunak ETAP menunjukkan nilai THDi sebesar 44,15% dengan spektrum yang mirip dengan data pengukuran lapangan. Perbedaan antara nilai THDi yang berdasarkan pengukuran lapangan dan simulasi mencapai kisaran 3% saja. Hasil simulasi dapat memverifikasi hasil pengukuran lapangan.","PeriodicalId":201799,"journal":{"name":"Jurnal Teknik Energi","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128448731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salah satu upaya untuk untuk mengurangi biaya produksi tanpa mempengaruhi hasil atau kualitas produksi adalah dengan memanfaatkan gas buang yang dihasilkan dari proses yang terdapat di pabrik baja terpadu. Salah satu gas buang yang dihasilkan adalah blast furnace gas (BFG) yang dihasilkan dari proses di Blast Furnace Plant. Salah satu cara untuk menurunkan konsumsi energi Listrik Khususnya di Blast furnace plant adalah dengan diaplikasikannya Top-gas Recovery Turbine (TRT). TRT merupakan suatu sistem yang dapat membangkitkan energi listrik dengan memanfaatkan gas buang yang dihasilkan dari bagian atas (top) Blast furnace yang dialirkan melalui Gas cleaning plant untuk selanjutnya memutarkan turbin-generator. Dengan adanya sistem TRT ini, BFG dapat dimanfaatkan secara maksimal dan dapat menambah pasokan listrik sehingga bisa mengurangi biaya energi listrik. Berdasarkan hasil perhitungan kapasitas terpasang TRT adalah sebesar 18 MW. Energi listrik yang dihasilkan adalah sebesar 117.121,5 MWh. Estimasi jumlah penghematan biaya listrik adalah sebesar 120,12 milyar/tahun. Dengan adanya TRT pengurangan emisi CO2 dalam satu tahun adalah sebesar 84,064 ton- CO2.","PeriodicalId":201799,"journal":{"name":"Jurnal Teknik Energi","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124943005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
