Introduction
Analysis of the core content of the standard
This standard specifies the full-process technical requirements for ground testing of the transmission chain performance of variable speed constant frequency wind turbine generator sets, covering 7 categories and 14 key tests, mainly including:
- Basic mechanical performance test (dynamic balance, inertia, etc.)
- Electrical characteristics verification (voltage distortion, grid adaptability)
- System dynamic response test (damping, semi-physical simulation)
- Extreme working condition verification (overspeed, overload)
Comparison of key technical requirements
| Test items | Accuracy requirements | Equipment specifications | Evaluation standards |
|---|---|---|---|
| Torque ripple | ＜1% of rated value | 0.5-level dynamometer | GB/T9239.1 |
| Vibration test | 0.2mm/s | 200Hz response frequency | GB/T35854 |
| Grid adaptability | THD＜3% | Class A electrical measuring instrument | GB/T36994 |
Detailed explanation of typical test methods
7.5 Key points for the implementation of overspeed test
The test requires the use of The inverter drives the generator to 1.2 times the rated speed for 2 minutes:
- Gearbox models shall evaluate vibration according to GB/T35854
- Direct drive models shall refer to GB/T25389.1 standard
- Focus on checking spindle deformation and bearing damage
Standard implementation recommendations
Laboratory construction requirements
- The flatness of the basic platform must reach GB/T22095-2008 Level 3
- Drive system torque control accuracy ≤1%
- Equipped with dual circuits for emergency stop (GB/T5226.1)
Test process optimization
It is recommended to perform the test items in the following order:
