A modern electrical power system is a complex technical facility, unique in terms of its scale and importance for human life.
The high level of openness and integration of electric power systems, combined with the pervasiveness of IT and internet technologies in daily life, has raised new challenges for the electric power sector. The requirements for these devices, their design and functionality have evolved alongside the electrical power systems they protect, in response to growing consumer and operation demands.
Today’s Protection, Automation and Control System (PACS) is a complex set of interrelated information systems covering all areas of electric power facility operation. The rapid development of computing and communication technologies has changed the protection and automation systems of electric power components.
