Applications of IEC 61850 in distribution automation

Distribution Automation (DA) is viewed as an integral component of the Smart Grid paradigm. It facilitates the employment of computer technology and communication infrastructure to advance management and operation of the distribution network from a semi-automated approach towards a fully automated one. SCADA systems, advanced sensors, and electronic controllers are integrated into the DA system in order to achieve the desired performance and reliability at the distribution network. Interoperability of all the components participating in the DA system requires communication standards covering not only the devices in the substation, but all the components from the substation to the point of interface with the end consumers. While the IEC 61850 standard was originally addressing applications and communications within the substation, recent work is undergone for extending it beyond the substation fence. With its object oriented structure, IEC 61850 can provide comprehensive and accurate information models for various components of distribution automation systems, while providing an efficient solution for this naturally multi-vendor environment. This paper provides some concrete examples on how IEC 61850 can be employed in the context of distribution automation applications, and what measures need to be taken to enable it to efficiently respond to some of the emerging technologies in DA systems.
