Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for integrating switching station automation devices according to the IEC61850 standard with industry automation field buses, such as MODBUS, require manual configuration due to the lack of field bus information in SCL files, hindering automated DTM generation and seamless integration.
Innovation Solution
A method that modifies the SCL technical manual file by incorporating mapping information for communication and functional parameters of the industry automation field bus, allowing the generation of a DTM component with encapsulated data and functions, which can be configured using FDT/DTM technology to map IEC61850 parameters onto field bus parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual configuration is used to integrate IEC61850 devices with industry automation field buses, then integration flexibility is maintained, but integration time and complexity increase significantly
Solution Approach 1:
The patent applies preliminary action by embedding field bus mapping information directly into the SCL configuration files during device documentation phase. This allows the mapping relationships between IEC61850 data objects and field bus parameters to be predefined and automatically processed, eliminating the need for time-consuming manual configuration during actual device integration while maintaining flexibility through the structured XML-based SCL format
2Productivity
If automated DTM generation from SCL files is implemented, then integration efficiency improves, but field bus information must be incorporated into SCL files increasing file complexity
Solution Approach 1:
The patent applies the nested doll principle by embedding field bus mapping information within existing SCL file structures using XML namespaces and custom elements. The field bus parameters are nested inside standard IEC61850 data object definitions, allowing automated DTM generation tools to extract both IEC61850 and field bus information from the same SCL file without creating separate complex configuration files
Solution Approach 2:
The patent introduces an intermediary layer in the form of standardized XML elements and namespaces that bridge IEC61850 data objects and industry field bus parameters. This intermediary structure allows automated tools to map between the two protocols systematically, enabling efficient DTM generation while maintaining manageable file complexity through structured intermediate representations
3Adaptability or versatility
If FDT/DTM technology is used to operate IEC61850 devices on field buses, then communication versatility is enhanced, but device configuration complexity increases due to manual setup requirements
Solution Approach 1:
The patent applies self-service by enabling automated DTM generation tools to automatically create FDT/DTM configuration files from SCL files containing embedded field bus mapping information. The system performs self-configuration by extracting device parameters, data objects, and mapping relationships from the SCL file and automatically generating the corresponding FDT/DTM configuration, eliminating manual setup complexity while maintaining the communication versatility of FDT/DTM technology
