What are the benefits of using IEC 61850 for real-time automation functions?
The results of an Australian project shows the capabilities of an IEC 61850 based SCADA solution that supports the integration of real-time automation functions into their platform based on the use of IEC 61131 logic programming and IEC 61850 as a means of communication for distributed automation functions.
The performance of simple Centralised Remedial Action Scheme (CRAS) implemented on a SCADA system has been evaluated and compared to the legacy methods to determine if the performance, security, reliability, scalability/flexibility and cost are justified considering the additional complexity of an integrated system. Experimental results show that the system delivers significant benefits including improved system reliability through reduced device count, improved safety with configurable operator interfaces, mobility services and remote diagnostic capabilities, and reduced engineering costs by providing a unified engineering environment that allows simple and seamless configuration based on the use of open standards.
Gaining an understanding of the capabilities of today’s real-time automation products and IEC 61850, along with new distributed automation and control functions will provide decision makers with the confidence to adopt more capable digital platforms and implement a smarter grid.
The additional complexity introduced with those highly integrated systems is justified. However, digital technology products will require organisations to develop specialised skills-sets, work processes and procedures to ensure a successful transition to new solutions and architectures.
