  • In order to complete engineering works of the digital substation, Both Data transmission among a variety of IEDs and HMIs, and single line diagram of the substation might be done based on XML documents published in IEC 61850 international standards. This kind of XML based engineering process for the digital substation must be implemented not by manual written work but by the engineering tool using a computer. But most of the engineering tools do not support system based engineering works such as single line diagram of the substation but have only function to set IEDs as single device unit. Accordingly, this paper presents a new design method of the system based engineering description applicable to real IEC 61850 based substation through analyzing the current international standard and its sampled engineering file, and shows implementation of the engineering tool of the digital substation with the result of this study.

  • The IEC 61850 communication standard is used worldwide, and within the country the new substation is built as a digital substation based on IEC 61850 from 2013, after field tests and R&D from 2007. Research on the development of digital substation operating system has been conducted mainly in large domestic companies, so the IED power application equipment for LCP are developed. However, there is still a lack of research in the field of systems that can accommodate all the field devices used for legacy substation and new digital substation. In this paper, we developed the 48VDC input modules and the 125VDC output modules which can construct proposed field information processing modules to IEC 61850 based type, and verified the field applicability from the state monitoring and control operation tests by using IEC 61850 client authentication program and Wireshark.

  • This study identifies the comparison of Technical specification and Characteristics of DC Protection Relay(ETCPU200) used in DC Distribution System in Korea. ETCPU200 has completed Field Test and approved its capability by finding out causes of recent operations through lately developed digital DC protection relay in parallel operation at Maebong-Substation, Sangbong-Substation, Nakseongdae-Substation, Euljirosaga-Substation, Jegi-Substation and Chongyangri T/P area. It also examines additional features for efficient System Analysis and Operations.

  • Korea Electric Power Research Institute has carried out verification of communication conformance on IEC 61850 based IEDs related to power IT project "Development of Prototype for Advanced Substation Automation System based on the Digital Control Technology". Owing to IEC 61850 international standard and digital substation automation system, IED testing process should be changed from the conventional way to the new way described in the paper. This paper describes IED testing procedures based on substation automation system using UML.

  • In this paper, DSPOCS(Digital Switchgear-Panel Operation and Control Solution) is designed, which is the intelligent inference based operation and control solution to obtain the safety and reliability of electric power supply in substation based on IED. DSPOCS is designed as a scheduled monitoring and control task and a real-time alarm inference task, and is interlinked with BRES(Bus Reconfiguration Expert System) in the required case. The intelligent alarm inference task consists of the alarm knowledge generation part and the real-time pattern matching part. The alarm knowledge generation part generates automatically alarm knowledge from DB saves it in alarm knowledge base. On the other hand, the pattern matching part inferences the real-time event by comparing the real-time event information furnished from IEDs of substation with the patterns of the saved alarm knowledge base.; Especially, alarm knowledge base includes the knowledge patterns related with fault alarm, the overload alarm and the diagnosis alarm. In order to design the database independently in substation structure, busbar is represented as a connectivity node which makes the more generalized graph theory possible. Finally, DSPOCS is implemented in MS Visual $C^{++}$, MFC, the effectiveness and accuracy of the design is verified by simulation study to the typical distribution substation.
