1 Sc pe

This p rt of IEC 614 0, whic is a tec nical sp cif i ation, provides a f ramework from whic

time-b sed an prod ction-b sed avaia i ty in icators of a win p wer station can b

derived It u ambig ou ly des rib s how data is categorised an provides examples of how

the data can b u ed to derive avai a i ty in icators

The a pro c is to a ply the terms an defi ition for the a pl ed information models

introd ced in IEC TS 614 0-2 -1 an IEC TS 614 0-2 -2 to a win p wer station

The b sic a pro c is b sed on the as umption that a win p wer station may b model ed

as one 'WTGS' re resentin a complete win p wer station The win p wer station is made

up of al WTGSs, f un tional services an b lan e of plant elements as se n f rom the p int of

common coupl n

It is not the intention of this sp cif i ation to def i e how time-b sed an prod ction-b sed

avai a i ty s al b calc lated Nor is it the intention to f orm the b sis for p wer c rve

p rforman e me s rements – whic is the o jective of IEC 614 0-12 However, the an exes

s ould b regarded as examples an g idel nes f or develo in method f or calc lation of

avai a i ty in icators

This doc ment also in lu es informative an exes with:

• examples of how to exp n the model to more services,

• examples of how to determine the information category f or the win p wer station,

• examples of how to exp n the model to b lan e of plant elements,

• examples of determination of lost prod ction,

• examples of avai a i ty algorithms f or prod ction b sed in icators,

• examples of other avai a i ty in icators,

Determination of the pro er inf ormation category f or the WPS is complex, as the res ltin

category is not simply made up of the minimum, maximum, s m or average of the elements

5 INFORMATION AVAILABLE (WPS)

Def i ition – The category INFORMATION AVAILABLE covers al time p riod , d rin whic

information on the WPS an external con ition is retrieved, log ed an stored man al y or

automaticaly to the extent that at le st one information category can b esta l s ed

It is recog ised that there may b circ mstan es when inf ormation is p rtialy avai a le

Qual f i ation f or INFORMATION AVAILABLE req ires s f f icient information to determine that

criteria f or man atory level 4 category are ac ieved

Inf ormation to determine the man atory inf ormation category can b derived f rom multiple

sources Sources can b

• the information category f rom the in ivid al WTGSs,

• meterin information,

• man al entries

For example the inf ormation category can b determined as INFORMATION AVAILABLE if

data tran mis ion from every sin le WTGS of a WPS is inter upted, as lon as data from a

me s rement s stem sti gives adeq ate information to determine the category of the WPS

This category covers al man atory inf ormation categories as de icted in Fig re 5
