Automating the Diagnosis of Occurrences in Power Plants Using Data from DFR and Sequence of Events: an Expert System Based Methodology

Analisa Disturbance Fault Recorder ( DFR ) Sebagai Alat Perekam Anomali Pada Gardu Induk Rangkas Baru

“…Tujuan dari sistem analisis otomatis akan mengubah data menjadi pengetahuan [25]. Mengotomatiskan analisis kejadian di pembangkit listrik menggunakan Digital Fault Recorders (DFR) sebagai fitur masukan, catatan osilografi [26] Dipenelitian ini penerapan DFR akan dianalisa pada UPT Cilegon ULTG RANGKAS. Pembangkit UPT Cilegon membawahi tidak kurang dari 30 unit gardu induk tegangan tinggi dan ekstra tinggi (GI/GITET) dengan kapasitas trafo terpasang mencapai 3810 / 895,5 MVA serta 1.568 tower penghantar transmisi dengan panjang jaringan mencapai 858,92 km sirkit.…”

Using disturbance records to automate the diagnosis of faults and operational procedures in power generators

“…Feature extraction is the processes used to obtain characteristics, such as current amplitude. The objective of this paper is to present a scheme for such tasks that takes into account specific aspects related to power generators, such as slow voltage variations and disturbances recorded due to normal operational procedures [6].…”

Expert Systems for Human, Materials and Automation

“…Although this investigation is usually performed off line, it has become common in case of severe contingencies to contact the DFR specialist to ask for his advice before returning the generator to operation. Thus the importance to perform the analysis as quickly as possible (Moreto et al, 2009). The excess of data that needs to be analyzed every day is a problem faced in most analysis centers.…”
