Modeling Intelligent Control Switch IEC 61850 Based Substation Automation Communication

Abstract

Abstract:With the advent of the new information technologies, the power communication service object is continuously enhanced by the modernization level of the switches architecture designed in the substation automation environment. In the futuristic plan, the communication network not only provides a transmission line between devices, but also takes into account the reliability and efficiency of the power system communication network. Many protocols are used for the provision of faster and more robust communication among control centers, Remote Terminal Units (RTUs) and Intelligent Electronic Devices (IEDs). These protocols support the exchange of a wide range of possible common data that is organized by a DATA-SET, such as in synchronized circuit breaker switching, distance protection and overcurrent protection. However, these protocols do not give the expected performance with standard switches architectures due to the remarkable traffic in power system communication. To address this issue, this paper modelled a substation automation switch based on the packet forwarder technique based on Generic Object Oriented Substation Event (GOOSE) protocol with different architectures of substation automation switches based International Electrotechnical Commission (IEC) 61850 standard. Finally, the simulations results found that the architecture of the four-switch system showed a significant performance, as compared with other architectures.

Vulnerability and Impact Analysis of the IEC 61850 GOOSE Protocol in the Smart Grid

“…These communication standards differ from one another in a number of factors, including protocol profile, communication medium (serial, Ethernet, WAN), mode of communication (client-server, peer-to-peer, publish-subscribe, unicast, multicast), communication bandwidth, multi-vendor inter-operability, support for security, etc. [ 10 , 14 , 31 , 32 ]. When moving from the older communication standard to the latest one, several communication criteria are improved, such as communication bandwidth, baud rate, scalability, support for several analog/digital devices, multi-vendor inter-operability, support for security, etc.…”

“…For SAS, IEC 61850 [ 9 , 10 , 11 , 12 , 13 , 14 ] has become the preferred communication standard because of its improved functionality and several communication requirements including scalability, high bandwidth, multi-vendor interoperability, and security support [ 4 , 6 , 11 , 22 ], which also motivated us to further assess the security vulnerabilities of IEC 61850-based protocols.…”

“…To ensure the protection of the smart grid Substation Automation System (SAS) and for reliable message transfer, various communication protocols are being used, which include Modbus/Modbus Plus, Distributed Network Protocol 3 (DNP3), IEC 60870, IEC 61850, and IEEE C37.118. Owing to its provision for security, high scalability, multi-vendor interoperability, and support for various Input/Output (I/O) devices, IEC 61850 [ 9 , 10 , 11 , 12 , 13 , 14 ] has become the de facto standard for substation communication within the smart grid. The Generic Object Oriented Substation Events (GOOSE) is one of the key communication protocols defined in IEC 61850, which provides a reliable and fast transmission of data and commands between intelligent devices within a substation and between substations.…”

Networked Closed-Loop Model for Smart On-Site Maintenance of Substation Equipment Using Mobile Networks

“…In order to break the limits on the physical location of space and simplify the system connection, based on the development of network and control technologies, Networked Control Systems (NCS) have been broadly applied in modern industry to address these problems [8][9][10][11].…”

AC Ship Microgrids: Control and Power Management Optimization

“…Minimize the mismatch between generation and load and to serve as many higher priority loads as possible in operational real time Maintaining reliable and secure communications is important for the operation of ship microgrids, especially with decentralized power management and control. Moreover, the communication between devices is time-critical and thus associated algorithms should be able to minimize delay and reduce computational complexity [86]. These requirements are very similar to those of the terrestrial microgrids and thus the communication methods developed for terrestrial microgrids can be extended for ship microgrids as well.…”
