Modeling an IEC61850 based substation automation system
2011 Annual IEEE India Conference, 2011This paper describes the development of an IEC 61850 based substation automation system (SAS) architecture. IEC 61850 is a standard for the design of electrical SAS. It defines the communication between IEDs in the substation and the related system requirements.

An Intrusion Detection System for IEC61850 Automated Substations
IEEE Transactions on Power Delivery, 2010This paper proposes the use of an intrusion detection system (IDS) tailored to counter the threats to an IEC61850-automated substation based upon simulated attacks on intelligent electronic devices (IEDs). Intrusion detection (ID) is the process of detecting a malicious attacker. It is an effective and mature security mechanism.
