IED GOOSE Message Subscription via CID Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The IEC 61850 standard for communication networks in power systems does not provide a method for an intelligent electronic device (IED) to specify which GOOSE messages it should receive, nor does it allow for modifying IED capabilities without firmware or software upgrades.
Innovation Solution
A description file and configuration tool are developed to create a section in the IED's CID file indicating which GOOSE messages to receive, and to link logic functions for programmable data binding, enabling dynamic data binding and optimizing file space and execution speed by prioritizing important data bits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the IEC 61850 standard is used for communication networks in power systems, then standardized communication protocols are established, but the standard does not provide a method for IEDs to specify which GOOSE messages they should receive
Solution Approach 1:
The patent applies preliminary action by pre-defining message subscription criteria in the IED configuration. The system预先 establishes subscription rules that automatically determine which GOOSE messages an IED should receive based on message characteristics and device capabilities, eliminating the need for complex post-deployment message selection configuration.
2Adaptability or versatility
If firmware or software upgrades are performed to modify IED capabilities, then functionality is enhanced, but system downtime and cost increase
Solution Approach 1:
The patent applies dynamics by enabling runtime modification of IED capabilities through configuration file updates. The system allows capability enhancements without firmware upgrades by dynamically loading new functionality from updated configuration files, permitting IEDs to adapt their message handling and subscription capabilities during operation without system downtime.
3Loss of information
If all GOOSE messages are processed by an IED, then complete information is available, but file space and execution speed are reduced
Solution Approach 1:
The patent applies the extraction principle by selectively filtering GOOSE messages based on predefined criteria. The system extracts and processes only the relevant subset of messages that match the IED's subscription criteria, removing unnecessary messages from the processing queue. This maintains essential information completeness while significantly improving execution speed by eliminating redundant message handling.
4Adaptability or versatility
If IEDs from different manufacturers are networked together, then system coverage is expanded, but communication protocol compatibility varies
Solution Approach 1:
The patent applies universality by implementing a standardized configuration file format that serves multiple functions across different IED manufacturers. The configuration file structure provides a universal interface for defining message subscriptions, device capabilities, and communication parameters, enabling IEDs from different manufacturers to interoperate reliably through a common configuration standard while maintaining their proprietary functionalities.
