Introduction
Core changes in standards and technological evolution
| Dimensions | 2008 Edition | 2024 Edition |
|---|---|---|
| Test methods | Mainly static test | Added dynamic whole group test + real-time digital simulation |
| Network security | Not specified | Added GB/T 36572 protection requirements |
| Test cycle | Fixed cycle | Allowed status maintenance adjustment |
| Intelligent station inspection | Not covered | Added SV/GOOSE message inspection |
Analysis of key inspection items
Key points for dynamic test implementation
The new standard requires that the following must be carried out for scenarios such as new stabilization devices and DC control and protection interfaces:
- The real-time digital simulation platform needs to build a complete primary system model
- The action reliability of the fixed value range of 0.95-1.05 times needs to be verified
- The interface test of the new energy control system needs to include power modulation timing verification
Special requirements for smart substations
| Inspection items | Traditional stations | Smart stations |
|---|---|---|
| Sampling test | Analog input | SV message reception test |
| Open-in test | Hard contact test | GOOSE communication interruption check |
| Insulation test | 1000V megohmmeter | ICD model connection needs to be disconnected |
Implementation suggestions
Inspection process optimization
- Factory acceptance stage: give priority to completing Control strategy function joint inspection
- During on-site inspection: use monitoring system sampling comparison to simplify partial inspection
- System transmission test: it is recommended to be carried out simultaneously with primary equipment maintenance
Risk control measures
Special attention should be paid when conducting fiber channel inspection:
- Channel attenuation detection should be carried out in conjunction with annual communication inspection
- Bit error rate threshold should be strictly controlled below 10-8
- Ultra-long channel transmission time can be relaxed to 30ms
