《GB/T 30370-2022火力发电机组一次调频试验及性能验收导则》由TC376（全国电站过程监控及信息标准化技术委员会）归口，主管部门为中国电力企业联合会。
Introduction
Analysis of dynamic changes in standards
| Innovation points | 2013 version | 2022 new version |
|---|---|---|
| Speed inequality | No specific range requirement | 3%-6% clear interval |
| Test load point | 3 benchmark conditions | Add deep peak load condition verification |
| Response indicator | Total response time only | Subdivided into lag + stability dual parameters |
Analysis of key technical parameters
Frequency measurement accuracy: The new version requires ≤0.003Hz. The test needs to give priority to calibrating the DEH system acquisition module
Dynamic response benchmark: Set 12 key assessment nodes, including the step time limit for reaching 75%/90% of the target value
Implementation suggestion module
Test preparation optimization checklist
- The DEH/TCS valve flow characteristics must complete the system confidence verification in advance
- The deep peak regulation mode of the thermal power unit requires a separate test plan
- Add the steam turbine speed regulation system filter parameter verification step
| Disturbance amplitude | Response time(s) | Load deviation control(±%) |
|---|---|---|
| ±0.067Hz | 2.7 | 0.85 |
| ±0.1Hz | 2.9 | 1.12 |
