We have posted a number of articles on this site regarding the benefits of digital substations, including partial conversions, to increase capacity, reduce space requirements, improve safety and improve substation functionality. We also touched upon the advantages of digital substation components for monitoring, diagnostics and reliability within the substation. The networking opportunities extend from there. As one example, for utilities that have upgraded to include multiple substations/digitalized assets, ABB offers the SDM600 System data manager, a comprehensive software solution for automatic management of service and cyber security relevant data across multiple assets. It provides disturbance record handling, cyber security management and maintenance and service data management.
