Introduction
Analysis of the core content of the standard
| Configuration tool type | Core functions | Key technical indicators |
|---|---|---|
| System configuration tool | SCD file management, virtual terminal visualization configuration, communication parameter verification | Support SSD file import, automatic generation of CRC check code |
| IED configuration tool | Device-specific configuration, model instantiation, parameter download | Automatically export CID files, and have a mistaken download prevention mechanism |
Detailed explanation of key technical requirements
Communication configuration specifications
The standard strictly limits the range of network parameters:
- GOOSE MAC address: 01-0C-CD-01-00-00~01-0C-CD-01-FF-FF
- SV VLAN-ID range: 000~FFFH (hexadecimal)
- APPID allocation rule: GOOSE (0000~3FFFH) and SV (4000~7FFFH) are independently encoded
Implementation suggestions
- Configuration tool development should follow the template conflict handling mechanism (ignore/replace/rename)
- In engineering applications, it is necessary to focus on checking the consistency of virtual terminal types (DO/DA matching)
- It is recommended to establish a SCD file version traceability system to record the modifier, content and reason
Standard Evolution Analysis
This standard forms a supporting system with GB/T 32890-2016. The main innovations include:
- For the first time, the classification management requirements of configuration tools are clarified
- A CRC verification mechanism for virtual terminals throughout the site is established
- Specification of consistency test cases (74 test scenarios in total)
