Introduction
Background of Standard Revision and Technology Evolution
This revision is based on the current status of secondary equipment technology development of smart substations, focusing on solving the three major problems found in the implementation of the 2016 version of the standard: unclear functional positioning, lack of data layer processing, and scattered visual display. The new version of the standard deletes non-core content such as status assessment, and adds protection action analysis and operation inspection function modules.
Core architecture and functional specifications
| Functional modules | 2016 version | 202X version |
|---|---|---|
| Operation monitoring | Basic status monitoring | Add Secondary virtual circuit physical connection visualization |
| Intelligent diagnosis | Performance indicator evaluation | Focus on fault recording and action logic analysis |
| Data upload | Not hierarchical | Clearly define the three-level architecture of process layer-station control layer-master station |
Key technical requirements
Virtual circuit visualization case
Taking the process layer switch as an example, the new standard requires the following:
- Display of virtual terminal connection relationships parsed by SCD files
- Mapping relationship between physical ports and logical links
- Real-time alarm positioning of abnormal communication
Implementation suggestions
It is recommended to advance in three stages:
- Phase I: Complete basic information access of protection devices
- Phase II: Realize secondary circuit topology reconstruction
- Phase III: Establish an intelligent diagnosis knowledge base
Special attention should be paid to the coordinated implementation with DL/T 860, GB/T 32901 and other standards.
