Routine Inspection of Wind Power Systems: Key Points to Ensure Safe Operation

Regular routine inspections of residential small wind power systems are crucial for preventing malfunctions, ensuring safety, and maintaining optimal power generation performance. Spending just a few minutes observing from the outside in, and from easy to difficult points, can help identify potential problems early.

**First Key Point:** Visual Inspection of Appearance and Environment

**Observe Operating Status:** From a safe distance, observe whether the turbine blades rotate smoothly and at a constant speed, without any abnormal swaying, violent vibration, or obvious imbalance. Listen for normal operating sounds, and any harsh friction, impact, or other unusual noises.

**Inspect Blades and Structure:** Check the blade surface for visible cracks, damage, or icing (in winter). Check the tower and all connecting bolts and cables (if any) for tightness, rust, or signs of loosening.

**Clean the Surrounding Environment:** Ensure that the area around the turbine, especially within the blade rotation range, is free of tree branches, power lines, kite strings, or other debris that could interfere with or entangle it.

**Second Key Point:** Inspect the Tower Base and Electrical Box

Tower Foundation Condition: Check the connection between the wind turbine tower and the foundation for stability, and inspect the concrete foundation for cracks or severe weathering.

Electrical Box Condition: Check the ground control box/inverter enclosure for integrity, lockability, and signs of animal bites or water ingress. Check the indicator lights or displays on the enclosure for normal operation and any fault alarm codes.

Third Key Point: Focus on Data and Performance

Monitor Power Generation Data: If the system is equipped with monitoring equipment (such as a mobile app or display meter), regularly check daily/weekly power generation data. A sustained and unreasonable decrease in power generation at similar wind speeds may indicate reduced system efficiency.

Observe Abnormal Behaviors: Pay attention to any abnormalities in household appliances caused by unstable voltage, or whether the system frequently starts and stops without warning.

Fourth Key Point: Special Inspections Before and After Special Weather Conditions

Before and After Strong Winds, Thunderstorms, or Typhoons: More thorough inspections are necessary, focusing on structural robustness and any damage.

After a severe winter: Check for ice buildup or damage and ensure electrical connections are dry.

After a long period of no wind: During the initial startup, briefly observe whether operation is smooth.

Safety First Principle:

Climbing the tower or touching rotating parts while the turbine is running is strictly prohibited.

All visual inspections should be conducted from a safe distance.

If any obvious structural damage (such as blade cracks, tower bending), abnormal noises, continuous alarms, or a complete shutdown is found, immediately disconnect the system power supply (if safe to do so) and contact professional service personnel. Do not attempt to disassemble or repair the turbine yourself.

Developing a habit of regular inspections is like giving your wind power system a "health checkup," ensuring its long-term safe and efficient service at minimal cost.
