Lost Production Contractual Turbine

This is a lost production signal, where the potential/theoretical energy is determined using the turbine’s availability contracts. Only if a status occurs, with a category that according to the turbine’s contract should be unavailable, Lost Production Contractual will be allocated to that status.

Technology

Wind

Remarks

Energy export is used as a fallback if there are no power values.

The contract is configured to use either the normal Lost production calculation or the GE Lost production calculation.

Three different signals for the normal Lost production are available for service, global, and custom contracts. They are called Lost Production (Contractual), Lost Production (Contractual Global), and Lost Production (Contractual Custom).

Equation

Normal Lost Production Calculation

Turbine.svg

Where:

ELP, contract+

is the Lost Production Contractual, clamped to the positive part. We have one signal per contract type: ELP, contract, service, ELP, contract, global, and ELP, contract, custom.

ATC

is the Time-based contractual availability.

Epotential+

is the actual production, clamped to the positive part.

Eactual+

is the Energy with fallback Energy or Power with fallback, clamped to the positive part.

Pcp, contract

is the Cascading potential power Contractual Cascading Potential Power - Wind. The Lost Production signal for each contract type uses the Cascading potential power Contractual for that type, that is, PCP, contract, service, PCP, contract, global, or PCP, contract, custom.

T

is the device resolution in hours.

GE Lost Production Calculation

Where:

ELP, GE

is the Lost production contractual GE. We have one signal per contract type: ELP, contract, service, ELP, contract, global , and ELP, contract, custom.

Eref

is Reference energy

ATC, site

is Site availability

ATC

is Contractual Time-based availability Time-based Contractual Avail.

ATC, i

is Contractual Time-based availability for primary reference turbine i

n

is the number of primary references for this turbine

T

is the device resolution in hours

Ee

is Energy Export

Ee, i

is Energy Export for primary reference turbine i

Pcp, contract

is Cascading Potential Power Contractual Cascading Potential Power - Wind. The Lost Production signal for each contract type uses the Cascading potential power Contractual for that type, that is, PCP, contract, service , PCP, contract, global, or PCP, contract, custom.
