“…The IDMT curve was obtained in any one phase according to the IED time of operation with injected increasing values of the fault currents while keeping the other two phase currents undisturbed. The substation rated current, trip current, and increasing values of trip currents injected from the omicron test kit are given in Equations ( 9)- (11).…”

Substations are becoming increasingly reliant on international electrotechnical commission (IEC)-61850-enabled devices. However, device compatibility with these standards does not guarantee interoperability when devices are taken from different manufacturers. If interoperability of multivendor devices can be achieved, then power utilities will be in a position to implement multivendor devices in substations. The study here presents the development and testing of a digital substation test platform that incorporates devices from different manufacturers. The process bus communication and protection operation of the intelligent electronic devices (IEDs) were tested to validate device interoperability. The testbed was tested for two IED process bus communications, generic object-oriented substation event (GOOSE) and sampled measured value (SMV). The GOOSE is travelling between IED to IED with an end-to-end (ETE) delay of 2 ms and the SMV read by the IEDs are the same as the injected real-time substation inputs 220 kV and 1 kA. Three IED protection studies (overcurrent, earth fault, and overvoltage) were performed, and IED response curves were obtained. In addition, data monitoring and client–server communications were studied using installed software tools. The testbed configuration in this study has faced some real-time challenges regarding differences in device edition, device firmware, and ethernet switch due to its multivendor approach. All the mentioned configuration issues were resolved in this study with successful testing and validation of the testbed. The study of this testbed will provide solutions to the problems associated with a multivendor system faced by substation engineers and will help them in opting for multivendor installations. This system can be extended in the future by installing more multivendor devices with complex network topology and a SCADA system.

“…In the substation, the monitoring, control, protection and other automation functions are provided by the Substation Automation System (SAS). The communication network within the substation is divided into three levels: station level, bay level and process level [2]. NCIT and Merging Unit are located on the process level.…”

“…At present, active work is under way to develop and introduce digital substations based on modern micro-processing control and relay modules with digital current and voltage instrument (optical) transformers [1,2,3]. Leading relay protection manufacturers have already successfully developed and launched production of microprocessor relay protection modules adapted to work with digital flows, using process buses according to Standard 61850-9-2LE.…”

“…To ensure utilities accept or embrace the process-bus, it is necessary to prove that the operating performance of protection and control schemes based on 61850-9-2 is equivalent or exceeds that of conventional hardwired schemes. This paper will experimentally assess the feasibility of protecting a feeder using prototype 61850-9-2LE [2] distance and differential relays at the local terminal of the feeder and similar, but conventional hardwired, relays at the remote terminal. Merging Units (MU) and Ethernet Switches from different manufacturers have been integrated into the scheme and issues related to interchangeability and time offsets assessed.…”

Substations are a fundamental part in electrical energy transmission and distribution. The role of a substation is to transfer and transform electrical energy by stepping up or down the voltage. To do this, high voltage switching equipment and power transformers are used, in addition to instrument transformers that supply the status of the primary system to the secondary equipment. Substation Automation Systems are then used to control, protect and monitor the substations. The IEC 61850 standard developed digital substation with most advanced techniques. The IEC 61850 standard define in its sub-clauses IEC 600448 and IEC 61850-9-2 about digital interface, digital communication and Sampled Values transmission over an Ethernet link called Process Bus. Process Bus technology mainly developed in order to reduce the usage of copper wiring at substation control by introducing IEC 61850-9-2 digital interface.

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.
