Wind Farm Wake Loss Calculator
Audit independently matched no-wake/observed generation with unavailable references, negative apparent wake loss preserved; no causal wake attribution or Jensen model. Caller independently establishes units, regime, calibration and applicability; this does not establish design-code compliance, authenticity, operational safety, treatment efficacy or a validated forecast.
Description
A wake-loss fraction compares observed generation with an independently supplied no-wake reference.
A wake-loss fraction compares observed generation with an independently supplied no-wake reference.1
Unassessed reference generation must remain separate from the known comparison. Use this tool to calculate wind Farm Wake Loss from the supplied measurements and assumptions.
When to use Wind Farm Wake Loss Calculator
Use this tool to calculate wind Farm Wake Loss from the supplied measurements and assumptions. Establish the SI units or caller unit basis, load signs, measurement interval, model conditions and independently chosen coefficients or references.
How to use Wind Farm Wake Loss Calculator and understand its results
- Establish the SI units or caller unit basis, load signs, measurement interval, model conditions and independently chosen coefficients or references.
- Enter callerIndependentNoWakeGenerationKwh, observedWakeAffectedGenerationKwh, knownMatchedGenerationFlags, using the field meanings and rules below, then run the tool.
- Read knownMatchedWakeLossFraction, unassessedReferenceGenerationKwh. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerIndependentNoWakeGenerationKwh | Caller independent no wake generation kwh | list of number | Required |
| observedWakeAffectedGenerationKwh | Observed wake affected generation kwh | list of number | Required |
| knownMatchedGenerationFlags | Known matched generation flags; binary 1=known, 0=unknown, in the order described below | list of number | Required |
Enter nonempty aligned nonnegative baseline and observed generation in kWh plus binary known flags. Require positive baseline summed over known rows; loss is one minus known observed sum divided by known baseline sum. Separately sum unassessed baseline generation. Observed generation may exceed baseline, giving negative loss; unknown rows do not enter the known denominator.
wakeLossFraction=1−ΣknownObserved/ΣknownBaseline; unassessedBaseline=ΣunknownBaseline Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| knownMatchedWakeLossFraction | Known Matched Wake Loss Fraction; follow the units, sign, ordering and evidence convention stated above | number |
| unassessedReferenceGenerationKwh | Unassessed Reference Generation Kwh; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
Unassessed reference generation must remain separate from the known comparison. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
