Various communication protocols are used within a typical industrial facility including Modbus RTU, DeviceNet and Profibus. These protocols used over the years have been in a Master-Slave configuration. Intelligent Electronic Devices (IEDs) are slaves to single or multiple masters with one-way communication with the IED acting as a data/controlled node to the master device. Control is implement...

IEC61850 communication standard for digital substation automation creates a new way to think about conventional protection scheme and configuration of substation. The presence of communication link in process bus makes a revolutionary change for future digital substation. This paper discusses briefly about process bus architecture and presents a new approach of thinking in busbar structure to m...

In order to adapt to the construction needs of the smart grid, smart substation need to solve the problem of protocol conversion between the conventional non-standardized condition monitoring equipment and the standardized monitoring system. This paper proposed a realization method of conversion method between Modbus and IEC61850. Object-oriented technology is used for information model on Modb...

In this paper, we study the use of a waveguide for IEC61850 communication using 802.11a radio. In particular the communication latency is analyzed. The latency of the system will depend on the traffic load and, thus, several test cases with different load are analyzed. In the paper we also describe a pilot installation commissioned at LyondellBasell Industries. The installed switchgear equipmen...

This book offers a compact guide to IEC61850 systems, including wide-area implementation, as it has been applied real substations worldwide.

In this paper, we propose an efficient and secure Authentication Protocol for Power systems (APP). The security analysis shows that APP is secure and resilient to various kinds of attacks. The numerical analysis and simulation results shows that APP is more efficient than TLS, a public-key based authentication protocol recommended by IEC61850.

During the last years utilities have been facing a strong trend towards new technologies and standards. The most significant task is to fundamentally transform the capabilities and bring new solutions that support better power quality supply. Standardization solution IEC 61850 in terms of protection, monitoring and control functions is a promising solution that provides a great impact on substa...

Today’s Substation Automation Systems (SAS) are formed by diverse microprocessor-based devices that carry out several operations such as metering, monitoring, protection and actuation. Standards, such as IEC61850, aim at providing abstract component-based solutions that improve scalability and ease the replacement of the devices. This paper discusses the different types of communication traffic...
