Performance considerations in digital substations

13th International Conference on Development in Power System Protection 2016 (DPSP), 2016
Today's substation automation, protection and control applications use IEC 61850 messaging typically only for control related and relatively static functions like blocking and interlocking schemes. With the introduction of process bus communication in digital substations copper wiring is being replaced by digital communication using IEC 61850.

Principle and Implementation of Substation-Area Backup Protection for Digital Substation

12th IET International Conference on Developments in Power System Protection (DPSP 2014), 2014
To solve the problems related to configuration and principle of backup protection in conventional substations, a new scheme of Substation-area Differential Backup Protection (abbr. SDBP) oriented to intelligent substations is proposed by this paper.

Cyber Security in Digital Substations

2022
Automation systems in modern power facilities can justifiably be viewed as computer systems (IT systems) mainly due to the way information is exchanged through the communication network. In general, all equipment installed in such systems today has several communication interfaces, which allows it to communicate independently to multiple systems and ...

Performance triangle in digital substation architectures

11th IET International Conference on Developments in Power Systems Protection (DPSP 2012), 2012
In the traditional domain of teleprotection signalling, there is a recognised triangle of performance. This triangle depends upon the required speed of communication, the expected dependability of the command, and the security of receipt. These three aspects are interlinked, and the correct balance of each is required in order to offer the traditional ...

Substation Digitization: A True Digital Twin for Substations and How to Get There

"The use of intelligent design software and workflows is fundamentally changing the way utilities design, construct, operate, and maintain substations. Benefits of adopting this technology include improved safety, fewer issues during construction, and increased quality through standardization of designs. A growing number of utilities are exploring the

Estimation of Digital Substation Reliability Indices

2020
The paper deals with the problem of improving the reliability of digital power supply facilities, namely digital substations. The goal of the study is to identify factors of a negative impact on the digital substation reliability indices. Based on the influencing factors analysis, technical measures for increasing reliability indexes are proposed ...
