Key Management Points for the Operation and Maintenance of Hybrid Wind and Solar Power Systems

Key Management Points for the Operation and Maintenance of Hybrid Wind and Solar Power Systems

The long-term reliable operation and efficient output of hybrid wind and solar power systems depend on systematic daily management and regular maintenance. Establishing clear management points and strictly implementing them is crucial to ensuring system safety and investment value.

I. Daily Operation Monitoring Key Points

Focus on observation and recording, and develop good habits.

Data Monitoring: Check the controller or monitoring platform daily, paying attention to "real-time power generation" (distinguishing between photovoltaic and wind power contributions), "battery charge/voltage," "daily cumulative power generation," and any fault alarms.

Sensory Inspection:

Look: Observe whether there is any obvious dirt on the surface of the solar panels; whether the wind turbine blades are intact and rotating smoothly (without violent shaking).

Listen: Pay attention to whether the wind turbine is operating normally, and whether there are any new abnormal friction or impact sounds.

Simple Recording: Record the system status before and after abnormal weather (such as strong winds, dust storms) in a logbook, as well as any minor anomalies.

II. Regular Preventive Maintenance Key Points

Execute according to plan to prevent failures.

Cleaning:

Solar panels: Clean every 1-3 months, depending on the environment, to remove dust, bird droppings, etc., which can significantly improve power generation efficiency. Perform cleaning in the early morning or evening.

Wind turbine: Check and remove foreign objects (such as moss, insect carcasses) from the blades to maintain their aerodynamic shape.

Mechanical Fastening and Inspection:

Quarterly/After strong wind seasons: Conduct a comprehensive inspection and tighten all connecting parts of the solar panel brackets, wind turbine towers, guy wires, foundation bolts, etc.

Inspect blades and structure: Regularly (e.g., every six months) use binoculars or other tools to check the wind turbine blades for cracks or damage; check the tower for corrosion or tilting.

Electrical System Inspection:

Check that all cables and terminals are secure and free from aging, damage, or animal gnawing marks.

Check that the lightning protection and grounding devices are reliably connected.

Keep battery terminals clean and securely connected, and ensure that their installation environment is ventilated and dry.

III. Seasonal and Special Maintenance

Responding to adverse weather:

Before strong winds/typhoons: Confirm that the wind turbine's automatic or manual typhoon protection function is working properly.

After the rainy season: Focus on inspecting the lightning protection system. After heavy snowfall: promptly remove snow accumulated on solar panels; wait for ice on wind turbine blades to naturally melt before inspection.

Battery maintenance (especially lead-acid batteries):

Regularly check electrolyte levels (for open-cell batteries) and terminal corrosion, keeping them clean.

Avoid prolonged over-discharge or overcharging of batteries.

IV. Performance Analysis and Fault Prediction Management

Data analysis: Compare power generation data monthly or quarterly. Under similar weather conditions, a continuous and unreasonable decrease in power generation should be considered a signal for troubleshooting potential problems.

Establish maintenance records:  Detailed records of each maintenance date, content, replaced parts, and problems found are valuable resources for fault diagnosis and predictive maintenance.

Define safety boundaries: All operations involving climbing towers, opening nacelles, or contacting high-voltage electrical components must be performed by professional personnel. User's daily management should be limited to ground-level visual inspection and data monitoring.

Summary: Systematized Management, Preventive Maintenance

Effective operation and maintenance management hinges on systematizing "daily monitoring, regular maintenance, data analysis, and safety regulations." The goal is to shift from "repair after failure" to "preventive maintenance." Through careful and continuous care, you can maximize system safety, extend equipment lifespan, and ensure it always operates at near-design efficiency, thus ensuring a long-term and stable return on your green investment. Remember, safety is paramount, and prevention is key to efficiency.
