T Implementation Issues with IEC 61850 Based Substation Automation Systems
نویسنده
چکیده
International Electro-technical Commission (IEC) has developed a new global standard, IEC 61850 for communication systems in power substations. This standard provides interoperability among the all communication devices within the substation. This paper presents basic features of communication systems proposed by IEC 61850, such as functional hierarchy, OSI-7 layer based communication, and process bus. To obtain complete advantages of the standard, it is important to consider all the major issues related to practical implementation. This paper discusses challenges for implementing new communication architecture, such as process bus and station bus. Further, the overall substation functional issues, and planning issues are also explained. Some possible solutions to several major implementation issues are suggested.

متن کاملSafety related, distributed functions in substations and the standard IEC 61850
-In a substation, a lot of distributed, safety related functions have to be performed. IEC 61850 is intended to replace all wires by serial communication. To achieve this goal IEC 61850 has to fulfill hard real-time criteria. Starting from the definition of these criteria the communication methods of IEC 61850 are investigated. The result shows the feasibility of these methods for interlocking ...
متن کاملTechniques for Securing Substation Automation Systems
Most critical infrastructure systems can be modeled as cyber-physical systems whose cyber components control the underlying physical components so as to optimize specified system objectives based on physical properties, physical constraints, and the current and estimated state of the system. Such systems usually require supports for security and performance guarantees: wrongly received or misse...
