Integrating substation automation
IEEE Spectrum, 1997Even though automation and remote control of electric power substations began as long ago as the early 1960s, the integration of intelligent electronic devices is still far from complete, especially in North America. The principal obstacle to greater interoperability is the plethora of incompatible hardware interfaces and protocols.

AI automates substation control
IEEE Computer Applications in Power, 2002The control of a substation is a very complex task due to the great number of related problems and, therefore, the decision variables that can influence the substation performance. Under such circumstances, the use of learning control systems can be very useful.

Network Security for Substation Automation Systems
2001The protection of critical infrastructure against electronic and communication network based attacks becomes more and more important. This work investigates the threat of network-based attacks on substations, the nodes of the electric power grid. Three fundamental types of attacks are derived and a secure communication protocol is proposed to counter ...

Substation automation technologies and advantages
IEEE Computer Applications in Power, 2001Automated substations can provide the information needed to maintain uninterrupted power to the customer at a lower maintenance cost. Substation automation is the integration of smart electrical equipment (e.g., circuit breakers, transformers, relays, etc.) that has the ability to monitor their functionality.

Communication redundancy for substation automation
2011 64th Annual Conference for Protective Relay Engineers, 2011Redundancy is one of the key requirements placed on power systems, it is particularly important for critical protection and substation automation applications. Redundant systems eliminate single points of failure and improve overall system availability, security and dependability. As Ethernet communication is becoming more and more common in protection

The budget approach to substation automation
IEE Half-Day Colloquium on Methods of Substation Automation, 1996The deregulated market increases the need for communication between the control centre and the substations. New systems (outage management, fault location, maintenance etc.) also need on-line information from the network about actual loading, equipment status, faults etc.

Substation automation: Matlab and OPC driven substation monitoring system
2016 International Conference on Microelectronics, Computing and Communications (MicroCom), 2016Power utilities, as a standard, adopt Supervisory Control and Data Acquisition (SCADA) systems for efficient power system operation, maintenance and development. The automation systems (viz. SCADA) need flexibility in design and its maintenance, for utilities to leverage maximum benefit apart from possibilities of being vendor locked.
