Synchronized Phasor Measurements in Digital Substations

2020 13th International Conference "Management of large-scale system development" (MLSD), 2020
We consider the symmetric components method on the direct, return, and zero sequences for the definition of short circuit currents. We present methods and algorithms of synchronized phasor measurements and their application on digital substations.

Network segregation in the digital substation

13th International Conference on Development in Power System Protection 2016 (DPSP), 2016
The substation is undergoing a great transformation, from hardwired operation technology to flexible information and communication technology. The great benefits of such transformation come with challenges, one of which is cyber security. Network segmentation and segregation, discussed in this paper, is one of the many layers of security that should be

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.

Modelling and Simulation of Digital Substation Automation for Inter-Substation Line Protection

2018 20th National Power Systems Conference (NPSC), 2018
Power systems have grown to become complex energy networks, they consist mainly of substations connected by transmission lines. These lines are key components of the networks and need to be protected to ensure the integrity and reliability of the system.

Tutorial on Networking for Digital Substations

2019 72nd Conference for Protective Relay Engineers (CPRE), 2019
A digital substation is one where all analog interfaces, such as current and voltage measurement, equipment status and alarms, and equipment control points are converted to digitized data directly at their source. This digital data, published using techniques described in the IEC 61850 standard, is then shared with other devices in the substation, and ...

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.

DIGITALIZATION OF HV SUBSTATIONS – VIRTUALIZATION CONCEPTS

Zbornik radova : UPRAVLJANJE I TELEKOMUNIKACIJE U EES
The concept of virtualization represents the very basics of the IEC 61850 standard, defined more than two decades ago and made official with the publication of the first edition of the Standard in 2003. The modularity of logical functions, the possibility of allocating protection and control functionalities through the appropriate display of the ...
