Network Data Integration Framework (supporting IEC61850 and CIM)
Xelas Energy offers a comprehensive set of products, related to the handling of network management information.
- Our IEC 61850 servers (embedded in network devices) enable equipment to communicate in the standardized IEC 61850 protocols.
- Our IEC 61850 Client-systems perform the management functions, and build a comprehensive object representation in their database.
Together, they manage the full 61850-domain: substations and all distributed renewable energy resources (often called DER or DRES)
Within DSOs or TSOs, there are many potential applications and users for this network information.
- Network engineering, operations and maintenance on the operational level
- Asset management, life cycle cost optimization and condition monitoring on the enterprise level.
The Smart Grid Architecture model provides a clear overview model about the complete infrastructure. It defines six “Zones”: process, field, station, operation, enterprise and market . While the IEC 61850 information model provides the standard on process, field and station level, the CIM (IEC 61970 and 61968) information model provides the standard on operations, enterprise and market level.
Information systems on enterprise level were traditionally based on network overview tables. But this no longer is sufficient for smart, dynamically changing grids. These information systems require sets of (life) network information. To support all these network related information needs, cross-departmental solutions are required.
The Xelas mediation/integration framework provides key technology to build this type of network data architecture.
Linking between the 61850 management domain and the CIM based webservices oriented architectures (SOA) requires a set of security sensitive functions, such as data acquisition, control front-end, gateway, proxy, object mapping services and role-based access control.
Integration of NETWORK MANAGEMENT information demands very high availability and flexibility. It also needs special support for network data formats, models and protocols. Its information streams may be very bulky, irregular or extremely time critical.
The Xelas network data mediation/integration framework is network integration technology, dedicated for all these needs. The framework provides a common (one link) enterprise service bus (ESB) solution between OT (61850) and IT (CIM).
Southbound, it interfaces with the IEC-61850 client systems open database. The client provides data acquisition, control front-end and role-based access functions. For non-61850 compliant equipment, other protocol adapters such as 5/101 or OPC, but also SNMP or ASCII are supported.
Within the framework, a two-step mediation process provides translation and mapping.
The adapters for protocol translation are meta-data driven, enabling easy updating in run time.
Logical mediation and message flow is provided via script-based mediation modules. Using rules and scripts here allows for extremely scalable, easy-to-understand and open logic management and – development, all possible without any operational interruptions.
Northbound adapters include full support of HTTP, HTTPS and IEC-61968-100 services, allowing direct connectivity to SOA-based business frameworks.
The Xelas network data integration framework runs completely distributed, enabling optimal scalability, and provides many additional functions, such as central configuration management and comprehensive logging services (important for additional security management).
