“…Time synchronization menjadi isu pada digital substation (Topolsky et al, 2018(Topolsky et al, , 2019 terutama pada komunikasi menggunakan SV, karena SV ini menggantikan data analog arus tegangan dari CT/PT konvensional. Adanya waktu yang tidak sikron, atau adanya delay pada frame SV bisa menyebabkan IED bekerja tidak sebagaimana mestinya (malfunction) (Serebryannikov et al, 2019) differential, busbar protection), yang menggunakan algoritma membandingkan nilai arus dari beberapa sumber.…”

“…Interface antara switchyard dan peralatan kontrol/proteksi dilakukan melalui jaringan ethernet, kabel fiber optic, menggantikan kabel tembaga yang digunakan pada gardu induk konvensional. Tegangan, arus dan sinyal digital dikirim oleh protokol komunikasi IEC 61850 berupa sampled value dan GOOSE (Bhardwaj et al, 2014;Pruthvi et al, 2013;Szela et al, 2018;Topolsky et al, 2018Topolsky et al, , 2019Wester et al, 2015). Current transformer (CT) dan voltage transformer (VT) konvensional atau Conventional Instrument Transformer (CIT) serta peralatan switchyard lainnya didigitalisasi menggunakan merging unit (MU) dan swithgear control unit (SCU).…”

Perkembangan pemanfaatan teknologi informasi dalam sektor ketenagalistrikan mendorong perkembangan teknologi gardu induk konvensional ke arah Digital substation. Sebagai pertimbangan sebelum diimplementasikan di PT PLN (Persero), maka dilakukan kajian literatur terkait standar, protokol komunikasi, network redundancy, time synchronization, serta kelebihan dan isu pada teknologi tersebut seperti yang disajikan pada makalah ini; selain itu, diskusi dengan pabrikan Digital substation yang ada di Indonesia juga dilakukan untuk memperkaya studi literatur yang dilakukan. Teknologi Digital substation mengacu pada standar IEC 61850, dapat dilengkapi dengan network redundancy berupa parallel redudancy protocol (PRP) atau high-availability seamless redudancy (HSR), serta precission time protocol (PTP) untuk kebutuhan sinkronisasi waktunya. Digital substation memiliki banyak kelebihan diantaranya yaitu kebutuhan copper wire yang rendah, transportasi dan space yang lebih sedikit, instalasi peralatan sekunder lebih singkat, penghematan biaya (instalasi, operasi, dan pemeliharaan), pemadaman lebih singkat, peningkatan keamanan dan utilisasi aset. Sedangkan isu yang ada pada Digital substation diantaranya maturity, interoperability, reliability, time synchronisation, network configuration dan bandwith management, cyber security, mixed mode, backward compatibility, suhu dan kelembaban. Selain itu, masih terdapat permasalahan pada substation automation system (SAS) yang sudah terpasang dalam rangka menuju teknologi Digital substation, namun belum tertangani dengan baik. Maturity level dari teknologi Digital substation menjadi bahan pertimbangan dalam penerapan teknologi tersebut di sistem ketenagalistrikan.

Background Information Detection in Substations Based on Anomaly Detection

et al. 2019

The substations are important parts of modern electrical grids. In this sense, it is necessary to detect the anomaly and problems in it. In this paper, we study on the information detection in substations based on traditional anomaly detection algorithms. The data flow from the background information is represented by feature vectors. And those from the historical data are used to build the background references. Afterward, the feature vector of the input data flow is examined using the anomaly detection algorithm. Based on the results, the anomaly in the background information in the substations can be found and located. Then, some high-precision identification algorithms can be further employed to recognition the type of the problems. In this way, the problems occurred in the substations can be found and solved in time.

Research and Application of One-key Sequence Control Technology for Substations

The substations are important parts of modern electrical grids. In this sense, it is necessary to enhance the management efficiency and robustness of the substations. The one-key sequence control technology system could simultaneously control several subsystems and make use of their functions to automatically operate the substations. In this study, three subsystems, i.e., monitoring subsystems, error analysis subsystem, and decision support subsystem are designed in the one-key sequence control technology system. All the background information from the substations is monitored, checked, detected to find the potential threats. The decision support subsystem provides suggestive ways to handle these problems. Therefore, through the reasonable use of the one-key sequence control technology, the overall effectiveness and efficiency of the substations can be enhanced. With the development of artificial intelligence technologies, the one-key sequence control technology system can be further improved with more powerful functions.
