Substation automation systems in review
IEEE Computer Applications in Power, 1998Screen-based substation automation projects are becoming increasingly common. Computerized substation automation systems have been installed for at least 5 years. In response to a number of issues, such as the safety of operational staff that operates a diverse range of equipment, operational efficiencies, and space savings, many electric utilities ...

Advanced networks for distributed measurement in substation automation systems
2013 IEEE International Workshop on Applied Measurements for Power Systems (AMPS), 2013The adoption of IEC 61850 in the deployment of Substation Automation System opens new scenarios to system design. The presence of a communication infrastructure connecting Intelligent Electronic Device (IED), sensors and protections may suggest the development of distribute measurement devices, where the sampling of the physical quantities and the ...

Evaluation of Time Gateways for Synchronization of Substation Automation Systems
IEEE Transactions on Instrumentation and Measurement, 2012The International Electrotechnical Commission (IEC) 61850 standard is widely used in substation automation system (SAS), even if some aspects related to the network-based time synchronization are still under investigation. The latest version of the IEC 61850 standard introduces IEEE 1588 Precision Time Protocol (PTP) for distributing time in the ...

Integrating recovery strategies into a primary substation automation system
2003 International Conference on Dependable Systems and Networks, 2003. Proceedings., 2004The DepAuDE architecture provides middleware to integrate fault tolerance support into distributed embedded automation applications. It allows error recovery to be expressed in terms of recovery strategies, i.e., lightweight code fragments separated from the application code. At run time, the middleware orchestrates their execution.
