Before you start
- Document essential functions, operating periods, resources and applicable component limits before work starts.
- Isolate energy sources, verify protective devices and identify work reserved for qualified trades.

Measure wind at the planned site and calculate realistic output
For “Measure wind at the planned site and calculate realistic output”, you check the required values, the limits of each component and the conditions at the installation site. You then record the result, reserve and an independent backup.

Lesson guide
Procedure
Prepare, complete each step and verify the result.
Success criteria
- Target, period and boundary for measure wind at the planned site and calculate realistic output recorded
- Inputs and outputs measured with units
- Sequence and polarity checked against data sheets
Practical task
- Complete “Step 1” and record every value with unit and operating condition.
- Name the stop condition and the safe fallback before continuing.
If conditions change
- Reduce demand or test a smaller isolated system before increasing capacity.
- Use a documented safe fallback when a component, resource or measurement is uncertain.
Detect and correct errors
- A value without unit or operating condition must be measured again and recorded.
- On heat, smell, vibration, leakage or unstable readings: stop, isolate and identify the cause before restart.
Learning objectives
- Measure wind speed for several months at the height of the planned rotor centre.
- Use the power curve for the actual turbine and account for turbulent air, the minimum wind speed needed to start, automatic shutdown and local permits.
- Measure the result and compare it with the permitted limits
What to check
Measure wind speed for several months at the height of the planned rotor centre. Use the power curve for the actual turbine and account for turbulent air, the minimum wind speed needed to start, automatic shutdown and local permits.

Measure wind at the planned site and calculate realistic output
Measure wind speed for several months at the height of the planned rotor centre. Use the power curve for the actual turbine and account for turbulent air, the minimum wind speed needed to start, automatic shutdown and local permits.
REAL SYSTEM VIEW
Mast, guying, clear airflow and service access show the realistic space requirement.
Dependencies and limits
Assess the resource over time at the site, not from one favourable moment. Measure wind speed, flow, head, fuel moisture or irradiation seasonally and apply conservative efficiencies.
Plan in the right order
Check space, sound, setbacks, water rights, emissions, fire load and maintenance access before choosing technology. Small sources often complement a system better than they guarantee supply alone.
Measure, maintain and switch to backup
Define a safe destination for surplus and a plan for shortage. Hybrid control may combine sources only within approved voltage, current and temperature limits.
Worked calculation or decision
Half the wind speed means theoretically one eighth of wind power; rooftop turbulence does not replace a clear mast site.
PROCEDURE
Carry out the lesson step by step
- 01 · Step 1
Measure wind speed for several months at the height of the planned rotor centre.
- 02 · Step 2
Use the power curve for the actual turbine and account for turbulent air, the minimum wind speed needed to start, automatic shutdown and local permits.
- 03 · Check the result
Measure the result, record its unit and operating condition, and compare it with the permitted limit for the component before continuing.
Materials and tools
- Site and seasonal measurement log
- Manufacturer curves or robust yield data
- Permit and setback check
- Maintenance, fire and shutdown plan
Safety and stop conditions
- Build combustion appliances, flues, towers, waterworks and fixed wiring only under local rules with qualified trades.
- Never burn fuel in unsuitable enclosed spaces: carbon-monoxide alarms, make-up air, clearance and approved flues are essential.
Typical mistakes
- Using the headline value for “Measure wind at the planned site and calculate realistic output” without checking its unit and operating condition
- Buying or connecting components before compatibility and protection limits are documented
- Treating nominal capacity, peak output or one favourable measurement as continuously usable supply
- Continuing after heat, smell, vibration, leakage, contamination or unstable readings appears
Final checklist
- Target, period and boundary for measure wind at the planned site and calculate realistic output recorded
- Inputs and outputs measured with units
- Sequence and polarity checked against data sheets
- Losses, temperature, season and reserve included
- Isolation and stop condition tested before full load
- Result, anomalies and next inspection entered in the log
DECISION CHECK
The measured result for “Measure wind at the planned site and calculate realistic output” differs from the planning value and one stop indicator appears. What comes next?
- Average it with the best previous reading
- Stop, isolate the affected path, identify the cause and repeat one controlled step
- Raise the fuse or alarm threshold
Show answer
Correct answer: Stop, isolate the affected path, identify the cause and repeat one controlled step
The worked reference was: Half the wind speed means theoretically one eighth of wind power; rooftop turbulence does not replace a clear mast site. A stop indicator invalidates continued operation until its cause and the relevant limit are resolved.
