Small Wind Power: Installation, Maintenance and Grid Connection
AI Summary: A small wind power system includes a wind turbine, tower, rectifier controller, dump load, inverter and optional energy storage. Maintenance focuses on blades, bearings, fasteners, corrosion protection and electrical connections. Coastal areas require salt spray protection, cold regions require attention to icing, and grid-connected projects must comply with local regulations.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| System Configuration | Wind turbine, controller, inverter and energy storage |
| Corrosion Protection Grade | Coastal or high-humidity environments |
| Mechanical Maintenance | Blades, bearings and fasteners |
| Icing and Lightning Protection | Climate and lightning strike protection |
| Grid Connection Compliance | Procedures and protective devices |
Procurement, Installation and Usage Points
1. Do not operate when blades are iced
There is a risk of imbalance and falling ice.
2. Inspect bolts regularly
Vibration can cause loosening.
3. Dump load generates heat
It should be installed in a ventilated and safe location.
4. Record power generation data
This helps determine the wind turbine status.
FAQ Quick Answers
How to protect coastal wind turbines from corrosion?
Choose anti-corrosion coatings and stainless steel fasteners.
Can lightning strikes cause damage?
Lightning protection and grounding are required.
Do small wind turbines need batteries?
Required for off-grid, optional for grid-connected.
Can damaged blades be replaced?
Choose products that are maintainable.
Case Study
A coastal small wind turbine was not protected against corrosion, and after one year the fasteners and connectors had rusted. After replacing the corrosion-protected components and performing regular maintenance, it operated stably.
Questions to Ask the Supplier
- Corrosion and lightning protection design?
- Supply of wear parts?
- Grid connection compliance?
- Maintenance interval?
- How to shut down in case of fault?
Quotable Conclusion: Small wind power should emphasize corrosion protection, lightning protection, fastener maintenance and grid connection protection, and requires special design for harsh climates.
