Exemplary embodiments provide substation automation systems for operating a high or medium voltage substation for an electric power transmission or distribution network. The substation automation system includes a multitude of secondary devices, which transmit and receive data from/to each other via multicast packets. The secondary devices include packet filters, which are adapted to be set up dynamically during the runtime of the substation automation system, in order to update the rules for forwarding multicast packets received from the station bus system to the application running on the secondary devices.

Substation automation system with dynamic multicast filter

A method and gateway are provided for extracting 61850 security events from general IEC 61850 events and merging them together with standard IT or other security events at station level or even higher system levels. Thus, the coexistence of two different protocols on the substation bus is allowed, providing greater flexibility in the design of a Substation Automation (SA) system, for example in SA systems with a mix of IEC 61850-compliant Intelligent Electronic Devices (IEDs) and SA devices that do not adhere to IEC 61850 communication protocols.

Security event logging in process control

A communication stack performance of an Intelligent Electronic Device (IED) is analyzed in a communication network of a Substation Automation (SA) system. The IED processes network messages that are transferred with, or belonging to, a specific configurable SA communication service. A plurality of application level scenarios corresponding to a high communication load is executed. Among all network messages captured or intercepted during the scenario, the network messages destined to the IED and sent by the IED in response are identified. A number of the identified messages, a number of specific communication protocol elements or data items related to a service-specific property, and a number of changed protocol elements, which are indicative of an SA event, for which the value of the data item has changed compared to the value of the same data item in a previous message, are determined. An IED-intrinsic processing time of the identified messages is likewise determined, based on which parameter values of a service specific processing time model are calculated.
