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.

Perspectives for the substation digital bays

2000 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.00CH37077), 2002
The evolution of the technology together with further cost optimisation goals lead to the definition of a new generation of architecture for the transmission substation at bay level. The architecture is constrained by various factors such as dependability, substation progressive refurbishment, use of different suppliers, etc.

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 ...

Calibration method for digital energy meters in digital substations

CPEM 2010, 2010
Digital energy meters are used in digital substations to measure electric energy, which receive IEC 61850 digital input. The traditional calibration methods for analog energy meters are not applicable to digital energy meters. In this paper we propose a method to calibrate digital energy meters.

The performance triangle in digital substation architectures

22nd International Conference and Exhibition on Electricity Distribution (CIRED 2013), 2013
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 ...
