Qhov kev thov nce ntxiv rau hluav taws xob hluav taws xob los txhawb nqa kev loj hlob thoob ntiaj teb yuav tsum muaj kev nqis peev hnyav hauv kev tsim hluav taws xob.Txawm li cas los xij, ntxiv rau txoj kev npaj nruab nrab thiab ntev ntev, cov kev nqis peev no tso siab rau cov peev txheej ntuj, uas yog
ua depleted vim yog kev ntxhov siab tas li rau ib puag ncig.Qhov zoo tshaj plaws lub tswv yim, yog li ntawd, kom tswj tau lub zog ntawm lub sij hawm luv luv yog kom tsis txhob nkim sij hawm thiab nce zog efficiency.Fais motors ua lub luag haujlwm tseem ceeb hauv lub tswv yim no;los ntawm ib ncig ntawm 40%
ntawm lub ntiaj teb no lub zog xav tau yog kwv yees muaj feem xyuam rau kev siv hluav taws xob lub cev muaj zog.
Raws li qhov tshwm sim ntawm qhov xav tau los txo qis kev siv hluav taws xob thiab cov pa roj carbon dioxide emissions, ntau lub tseem fwv thoob ntiaj teb tau tsim cov kev cai hauv zos, tseem hu ua MEPS (Cov Qauv Ntsuas Hluav Taws Xob Tsawg) rau ntau hom khoom siv,
suav nrog cov tshuab hluav taws xob.
Txawm hais tias cov kev cai tshwj xeeb ntawm MEPS no txawv me ntsis ntawm cov teb chaws, kev ua raws li cov qauv hauv cheeb tsam xws li ABNT,IEC,MG-1, uas txhais cov qib efficiency thiab kev xeem txoj hauv kev los txiav txim cov kev ua tau zoo, tso cai rau ib tug standardization ntawm lub ntsiab lus txhais, kev ntsuas thiab luam tawm hom ntawv rau efficiency cov ntaub ntawv ntawm lub cev muaj zog manufacturers, simplifying qhov tseeb motors xaiv.
lub zog efficiency ntawm peb-theem motors uas tsis yog nres motors, Ex eb nce kev ruaj ntseg motors, los yog lwm yam
Lub cev muaj zog tiv thaiv tawg, nrog rau cov zis tawm sib npaug lossis siab dua 75 kW thiab sib npaug lossis qis dua 200 kW, nrog
2, 4, lossis 6 ncej, yuav tsum sib haum rau yam tsawg kawg nkausIE 4qib efficiency tau teev tseg hauv Table 3.
Txhawm rau txiav txim siab qhov ua tau zoo ntawm 50 Hz motors nrog cov ntsuas hluav taws xob tso tawm PN ntawm 0,12 thiab 200 kW tsis tau muab rau hauv Cov Lus 1, 2 thiab 3, cov qauv hauv qab no yuav tsum siv:
ηn = A* [log1o(Pv/1kW)]3 + BX [log10(PN/1kW)]2 + C* log10(PN/1kW)+ D.
A, B, C thiab D yog interpolation coefficients yuav tsum tau txiav txim raws li cov lus 4 thiab 5.
