Introduction
GB/T 19068.1—2017 Standard Overview
GB/T 19068.1—2017 "Small Wind Turbines Part 1: Technical Conditions" is a national standard of the People's Republic of China, which is used to specify the technical requirements of small horizontal axis wind turbines for grid-connected or off-grid applications. This standard applies to small wind turbines with a rotor swept area of no more than $200~\mathrm{m^{2}}$ and a voltage of less than $1000~\mathrm{V}$ for AC or $1500~\mathrm{V}$ for DC.
Background of Standard Formulation and Technological Evolution
This standard is a revision of GB/T 19068.1—2003. The main improvements include:
- Expanded the scope of application
- Adjusted the content of generators
- Introduced the GB/T17646 design grade classification method
- Modified the cut-in wind speed and rated wind speed requirements
Comparison of core technical conditions
| Items | Old version of the standard (GB/T 19068.1—2003) | New version of the standard (GB/T 19068.1—2017) |
|---|---|---|
| Scope of application | Only applicable to off-grid wind turbines | Extended to grid-connected and off-grid applications |
| Cut-in wind speed | Not specified | Not greater than $4.0~\mathrm{m/s}$ |
| Rated wind speed | Not specified | Not greater than $11.0~\mathrm{m/s}$ |
Implementation Suggestions and Precautions
Implementation Suggestions:
- Ensure that the unit model complies with JB/T 7879 requirements
- Select a suitable generator and controller that meet the requirements of GB/T10760.1 and GB/T 34521 respectively
- Perform power characteristic test and durability test in accordance with the standards
Notes:
- Pay attention to the ratio of the maximum operating speed to the rated speed of the unit
- Ensure that the painting, marking and packaging meet the requirements of JB/T5673
- Properly preserve the accompanying documents, including the user manual and technical manual
