Wind energy generation systems - Part 26-3: Availability for wind power stations (IEC/TS 61400-26-3:2016)
This part of IEC 61400, which is a technical specification, provides a framework from which
time-based and production-based availability indicators of a wind power station can be
derived. It unambiguously describes how data is categorised and provides examples of how
the data can be used to derive availability indicators.
The approach is to apply the terms and definitions for the applied information models
introduced in IEC TS 61400-26-1 and IEC TS 61400-26-2 to a wind power station.
The basic approach is based on the assumption that a wind power station may be modelled
as one 'WTGS' representing a complete wind power station. The wind power station is made
up of all WTGSs, functional services and balance of plant elements as seen from the point of
common coupling.
It is not the intention of this specification to define how time-based and production-based
availability shall be calculated. Nor is it the intention to form the basis for power curve
performance measurements – which is the objective of IEC 61400-12. However, the annexes
should be regarded as examples and guidelines for developing methods for calculation of
availability indicators.
This document also includes informative annexes with:
• examples of how to expand the model to more services,
• examples of how to determine the information category for the wind power station,
• examples of how to expand the model to balance of plant elements,
• examples of determination of lost production,
• examples of availability algorithms for production based indicators,
• examples of other availability indicators,
• examples of application scenarios.

Sistemi za proizvodnjo energije na veter - 26-3. del: Razpoložljivost vetrnih elektrarn (IEC/TS 61400-26-3:2016)
ICS: 27.180
Ta del standarda IEC 61400, ki je tehnična specifikacija, zagotavlja okvir, iz katerega je mogoče izpeljati indikatorje razpoložljivosti vetrne elektrarne, ki temeljijo na času in proizvodnji. Nedvoumno opisuje, kako so podatki kategorizirani in ponuja primere, kako se lahko podatki uporabijo za pridobivanje kazalnikov razpoložljivosti.
Pristop je uporaba izrazov in definicij za uporabljene informacijske modele, uvedene v standardih IEC TS 61400-26-1 in IEC TS 61400-26-2, pri vetrni elektrarni.
Osnovni pristop temelji na predpostavki, da se lahko vetrna elektrarna oblikuje kot en »sistem za proizvodnjo vetrne turbine«, ki predstavlja popolno vetrno elektrarno. Vetrna elektrarna je sestavljena iz vseh sistemov za proizvodnjo vetrne turbine, funkcionalnih storitev in ravnovesja rastlinskih elementov, kot je razvidno iz skupne priključne točke.
Namen te specifikacije ni opredeliti, kako je treba izračunati razpoložljivost na podlagi časa in proizvodnje. Prav tako ni njen namen, da bi bila podlaga za meritve delovanja krivulje električne energije — kar je cilj standarda IEC 61400-12. Vendar naj bi dodatke obravnavali kot primere in smernice za razvoj metod za izračun indikatorjev razpoložljivosti.
Ta dokument vsebuje tudi informativne dodatke s:
• primeri, kako razširiti model na več storitev,
• primeri, kako določiti kategorijo informacij za vetrno elektrarno,
• primeri, kako razširiti model na ravnovesje rastlinskih elementov,
• primeri ugotavljanja izgubljene proizvodnje,
• primeri algoritmov razpoložljivosti za indikatorje, ki temeljijo na proizvodnji,
• primeri drugih indikatorjev razpoložljivosti,
• primeri scenarijev uporabe.
