Remote Access Gateway to Power Plant Automation Equipment With Cybersecurity Functions (Functionalities, Work Systems)

This article describes a remote access method to substation automation equipped with cybersecurity functions. It describes the creation of remote supervision systems (called also “concentrators”) for protection systems, the changes that have occurred in recent years in their implementation and functions, as well as some innovative features of the new technology developed by the authors. The most important features of the new 3rd generation remote supervision systems have been identified, greatly increasing the security of remote connections to automation systems installed in power plants and the flexibility of their operation.
