Review of digital substation equipment and technical specification in Indonesia

Abstract

Digital substation concept improves substations in advance by enhancing the equipment at station level, bay level, and process level. This enhancement of substation requires changes of equipment at those levels. The design needs to meet each equipment’s compatibility with the others. However, some manufacturers of the digital substation in Indonesia provide different specifications for the equipment at the same level. This condition causes challenges of implementation design of the digital substation in existing substations. To enhance existing substations including conventional substation and modern substation, the digital substation specification and equipment are reviewed. The reviews are based on digital substation standards including communication protocol, network redundancy, and time synchronization. After the specification study, the provided equipment in Indonesia are compared based on their technical specification. The technical specifications are compared at station level, bay level and process level based on provided equipment in Indonesia. The compatibility study is analyzed by using provided equipment, following with the implementation study in Indonesia. This paper provides reviews of the technical specification gap of existing substations compared to the digital substation. Finally, the consideration of choosing technical specifications also provided when implementing the digital substation in Indonesia.

Plans for upgrading existing conventional 150 kV substations into digital substations in Sulawesi - Indonesia, accompanied by financial studies

“…While the passive redundancy type only has one active link, and one other link is in standby mode. The redundancy protocols commonly used are Rapid Spanning Tree Protocol (RSTP), High Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP) [3], as presented in Figure 6.…”

“…The Indonesian government has signed the Paris Agreement to the United Nations Framework Convention on Climate Change (UNFCCC) on December 21st, 2015, in New York, United States, which is a climate change framework convention organized by the United Nations (UN) [1] [2]. Indonesia's commitment through the Nationally Determined Contribution (NDC) document in November 2016 is to set a target for reducing greenhouse gas (GHG) emissions by 29% (own ability) or 41% (with international assistance) by 2030 and renewable energy mix target by 23% in 2025 [3], which is until 2020 the renewable energy mix level has only reached 14.9% (based on IESR 2021). Figure 1 shows the condition.…”

Study on Potential Utilization of New Renewable Energy to Support the Electricity System in Warudoyong Area

“…The trilemma of energy in energy security, equity (energy equity), and environmental sustainability must all be considered while planning the electric power system [8]. Primary energy management [9], infrastructure [10]- [12] and operations [13], and the ability to satisfy current and future needs [14], [15] are all aspects of energy security. It is, of course, critical to pay attention to electricity assets in order for them to continue to function optimally [16]- [19].…”

Analyzing the Potential for Utilization of New Renewable Energy to Support the Electricity System in the Cianjur Regency Region

“…In planning the electric power system, it must also accommodate the trilemma of energy in the form of energy security, equity (energy equity), and environmental sustainability. Energy security includes primary energy management [9], reliability of infrastructure [10]- [12] and operations [13], and the ability to meet current and future needs [14], [15]. Of course, it is important to pay attention to electricity assets so that they can continue to operate optimally [16]- [19].…”
