INTRODUCTION

The IEC 614 0-2 series defines information models an inf ormation ex han e models f or

monitorin an control of win p wer plants The model n a pro c (f or inf ormation models

an information ex han e models) of IEC 614 0-2 -2 an IEC 614 0-2 -3 u es a stract

definition of clas es an services s c that the sp cification are in e en ent of sp cif i

commu ication protocol stac s, implementation , an o eratin s stems The ma pin of

these a stract def i ition to sp cific commu ication prof iles is def i ed in IEC 614 0-2 -4

This doc ment def i es an inf ormation model for con ition monitorin inf ormation an explain

how to u e the existin definition of IEC 614 0-2 -2 as wel as the req ired exten ion in

order to des rib an ex han e information related to con ition monitorin of win turbines

The models of con ition monitorin inf ormation defined in this doc ment may re resent

information provided by sen ors or by calc lation

In the context of this doc ment, con ition monitorin me n a proces with the purp se of

o servin comp nents or stru tures of a win turbine or win p wer plant for a p riod of time

in order to evaluate the state of the comp nents or stru tures an an c an es to it, in order

to detect e rly in ication of imp n in f ai ures With the o jective to b a le to monitor

comp nents an stru tures recorded u der a proximately the same con ition , this doc ment

introd ces the o erational state bin con e t The o erational state bin con e t is

multidimen ional in order to f it the purp se of sortin complex o erational con ition into

comp ra le circ mstan es

Con ition monitorin is most f req ently u ed as a predictive or con ition-b sed maintenan e

tec niq e (CBM) However, there are other predictive maintenan e tec niq es that can also

b u ed, in lu in the u e of the h man sen es (lo k, l sten, fe l, smel) or mac ine

p r orman e monitorin tec niq es These could b con idered to b p rt of the con ition

monitorin

Con ition monitoring te hnique

Con ition monitorin tec niq es that generate information to b model ed in lu e, but are not

l mited to, me s red or proces ed values s c as:

a) vibration me s rements an analy is;

b) oi de ris me s rement an analy is;

c) temp rature me s rement and analy is;

d) strain gau e me s rement an analy is;

e) acou tic me s rement an analy is

Comp nents an stru tures can b monitored by u in automatic me s rement retrieval or

via a man al proces

Con ition monitoring d vic s

The con ition monitorin fu ction may b located in dif ferent ph sical devices Some

inf ormation may b exp sed by a turbine control er device (TCD) whi e other information may

b exp sed by an ad itional con ition monitorin device (CMD) Variou actors may req est

to ex han e data values located in the TCD an /or CMD A SCADA device may req est data

values f om a TCD an /or CMD; a CMD may req est data values fom a TCD The information

ex han e b twe n an actor an a device in a win p wer plant req ires the u e of

5.1 Ov rview

The primary o jective of con ition monitorin is to detect s mptoms of a p tential f aiure of a

win turbine comp nent b fore it le d to fu ctional fai ure res ltin in seriou damage or

destru tion of the win turbine

In con ition monitorin s stems, predef i ed trig ers are a pl ed to initiate a seq en e of

events, f or example is uin an alarm to the local SCADA s stem or sen in a mes age to a

monitorin centre in order to prevent further damage on comp nents or stru tures In general,

s c mes ages can b u ed by a con ition monitorin s p rvision fu ction to generate

actiona le information whic can b u ed by a service organization to cre te work orders an

initiate action Fig re 2 i u trates the information flow of a s stem u in con ition monitorin

to p rf orm con ition b sed maintenan e

Con ition monitorin is mainly as ociated with the fol owin kin s of information

a) Time wavef orm record (samples) of a sp cific time interval to b ex han ed either

directly or as proces ed values for analy is (e.g ac eleration, p sition detection, sp ed,

stres detection)

b) Statu inf ormation an me s rements (s n hronized with the waveform record )

re resentin the turbine o eration con ition

c) Res lts of time waveform record analy is of vibration data (s alar values, ar ay values,

statistical values, historical (statistical) values, cou ters an statu information)

d) Res lts of, for example, oi de ris analy is

The con ition monitorin information can b des rib d by sp cified data atributes, trig er

o tion an data o jects of the fol owin common data clas es:

• con ition monitorin me s rement (CMM);

• me s rement value (MV);

• s alar value ar ay (SVA);

• complex me s rement value (CMV);

• complex me s rement value ar ay (CMVA);

• con ition monitorin bin (CMB);

• alarm (ALM)

The purp se of this doc ment is to model con ition monitorin information by u in the

inf ormation model n a pro c as des rib d in 6.2.2 of IEC 614 0-2 -1:2 0 an by

exten in the inf ormation model as sp cified in Clau e 5 of IEC 614 0-2 -2:2 15 with an

ad itional logical node WCON for model n information sp cif i to con ition monitorin of

win p wer plants

As the WCON clas is model ed u in the a pro c of IEC 614 0-2 -1 an IEC 614 0-2 -2,

the information ex han e models as sp cif ied in IEC 614 0-2 -3 an the ma pin to

5.4 Operational state bin conc pt

5.4.1 Ge eral

In order to des rib the en ironment f or a set of con ition monitorin me s rements, the

o erational state bin con e t has b en develo ed A wind turbine o erates in prin iple over a

wide ran e of win sp ed cau in a large variety of lo d on the mec anical stru tures An

ada tive monitorin tec niq e is often a pl ed to sec re a hig er degre of rel a i ty an

re e ta i ty of me s rements u ed to detect develo in faults in the f ul o eratin ran e,

th s red cin the ris of trig erin false alarms In order to ada t to the varyin o eratin

con ition , data can b stored ac ordin to several o erational states in multiple dimen ion

The b sic prin iple of con ition monitorin is to o serve the evolution of sp cif i me s red

varia les by comp rin new me s rements with previou me s rements The ef fect of

c an es in o erational con ition can b l mited by comp rin information b lon in only to

the same o erational state bin

5.4.2 Ex mple of how to u e a tiv p wer a a operational state

Active p wer levels are u ed f or the ada tive monitorin tec niq e rather than the win sp ed

as the vibration level me s red an the stres on the turbine comp nents are fou d to b

closely related to the active p wer prod ction of the turbine By u in the active p wer level

as me s rement trig er, it is also en ured that vibration me s rements are recorded only

when a win turbine is prod cin active p wer

An example of vibration data f rom the generator Drive En (DE) whic are in ivid al y

comp red to trig er lmits for five dif ferent “active p wer bin ” with in ivid al alarm trig er

levels is given in Fig re 4
