Introduction
Analysis of the core content of the standard
GB/T39627-2020 stipulates the technical requirements for 9 types of devices, including intelligent master control devices and intelligent terminals. Its technical framework presents three major characteristics:
Comparison of key technical requirements
| Device type | Communication interface | Core function | Reference standard |
|---|---|---|---|
| Intelligent master control device | MMS×2+GOOSE×2 | PID adjustment, logic programming | DL/T578 |
| Intelligent terminal | GOOSE×2 | DI/DO/AI/AO acquisition | DL/T5413 |
| Merging unit | SV expandable | Electronic transformer access | DL/T282 |
Key points for standard implementation
Communication protocol implementation case
In the upgrade and renovation of a hydropower station, the intelligent speed regulator adopts the MMS+GOOSE+SV three-network separation architecture:
- MMS protocol transmits slow variables such as guide vane opening (cycle ≥ 100ms)
- GOOSE protocol transmits power-on command and other control instructions (delay <10ms)
- SV protocol transmits machine-side voltage sampling value (sampling rate 4kHz)
Technology evolution analysis
Compared with traditional hydropower plants, this standard highlights three major innovations:
- Networked sampling: allows SV sampling values to be obtained through merging units
- Functional decoupling: concentrates basic functions such as DI/DO on intelligent terminals
- Safety redundancy: key devices need to maintain hard-wired control capabilities in the event of network failure
Test verification requirements
Electromagnetic compatibility test adopts Level 4 severity, among which:
- Electrostatic discharge: ±15kV air discharge
- Surge impact: ±4kV (power line)
- Fast transient: ±4kV (signal line)
