Zinthu ndi Zochitika zaMphamvu mitas' No-load Behavior

Pamene mita ya mphamvu ikugwira ntchito, zinthu ziwiri ziyenera kukwaniritsidwa.(1) Sipayenera kukhala pompopompo mu koyilo yapano ya mita yamagetsi;(2) mbale ya aluminiyamu ya mita yamagetsi iyenera kusinthasintha mosalekeza kupitilira bwalo lathunthu.

Khalidwe lopanda katundu wa mita ya mphamvu lingadziwike kokha ngati zinthu ziwiri zomwe zili pamwambazi zakwaniritsidwa nthawi imodzi.Ngati khalidwe losanyamula katundu limachitika mopitirira 80% ~ 110% voliyumu yovotera, malinga ndi malamulo oyenerera, mita yamagetsi ndiyoyenerera, yomwe singatengedwe ngati khalidwe lopanda katundu;koma zikafika kwa ogwiritsa ntchito, monga kubwezeredwa kwa magetsi kumakhudzidwa, mwachiwonekere kuyenera kuonedwa ngati khalidwe lopanda katundu m'malo mwachizolowezi.

Kuti apange chigamulo cholondola, kusanthula kumapangidwa motsatira zomwe zili pamwambapa:

I. Palibe mphamvu mumayendedwe apano a mita yamagetsi

Choyamba, wogwiritsa ntchito sagwiritsa ntchito kuunikira, mafani, TV ndi zipangizo zina zapakhomo, zomwe sizikutanthauza kuti palibe panopa mu dera lamakono la mita yamagetsi.Zifukwa zake ndi izi:

1. Kutuluka mkati

Chifukwa cha kuwonongeka, kuwonongeka kwa mawaya amkati ndi zifukwa zina, kulumikizidwa kwa magetsi kumachitika pansi ndipo kutayikira kwa madzi kungapangitse mita kugwira ntchito nthawi yotseka.Izi sizikugwirizana ndi chikhalidwe (1), choncho siziyenera kutengedwa ngati khalidwe lopanda katundu.

2. Tengani mita yamagetsi yaying'ono yolumikizidwa kumbuyo kwa mita ya master monga chitsanzo.Chowotcha padenga popanda tsamba chimayatsidwa molakwika m'nyengo yozizira.Ngakhale kuti palibe kugwiritsiridwa ntchito kwamagetsi kodziwikiratu popanda phokoso ndi kuwala, mita yamagetsi yakhala ikugwira ntchito ndi katundu, ndipo ndithudi siingakhoze kuonedwa ngati khalidwe lopanda katundu.

Chifukwa chake, kuti muwone ngati mita yamphamvu yamagetsi yokha ikusokonekera osagwira ntchito, chosinthira chachikulu pamagetsi amagetsi amagetsi chiyenera kulumikizidwa, ndipo mzere wagawo kumapeto kwa chosinthira chachikulu uyenera kulumikizidwa nthawi zina. .

II.Meta yamagetsi sayenera kusinthasintha mosalekeza

Pambuyo kuonetsetsa kuti palibe panopa m'dera panopa wa mita magetsi, zikhoza kudziwa ngati palibe katundu khalidwe kapena ayi zochokera chakuti ngati mbale mita mosalekeza atembenuza.

Kuweruza mozungulira mosalekeza ndikuwunika pawindo ngati mbale ya mita imazungulira kawiri.Mukatsimikizira kuti simukunyamula katundu, lembani nthawi t(mphindi) ya kasinthasintha kulikonse komanso c(r/kWh) ya mita yamagetsi, ndikubweza mtengo wamagetsi motsatira njira iyi:

Magetsi obwezeredwa: △A=(24-T) ×60×D/Ct

Mu chilinganizo, T amatanthauza nthawi yogwiritsira ntchito magetsi tsiku ndi tsiku;

D amatanthauza kuchuluka kwa masiku a mita yamagetsi osanyamula katundu.

Ngati mayendedwe opanda katundu akugwirizana ndi njira yozungulira ya mita yamagetsi, magetsi ayenera kubwezeredwa;ngati njirayo ndi yosiyana, magetsi ayenera kuwonjezeredwa.

III.Zochitika zina zamakhalidwe osanyamula mita yamagetsi:

1. Koyilo yamakono ndi yochepa-yozungulira chifukwa cha kuchulukirachulukira ndi zifukwa zina, ndipo voteji yogwira ntchito maginito imakhudzidwa ndi izi, zomwe zimagawanika m'magawo awiri a flux mu malo osiyanasiyana ndi nthawi yosiyana, zomwe zimapangitsa kuti palibe katundu wogwira ntchito.

2. Magawo atatu ogwiritsira ntchito watt-hour mita samayikidwa molingana ndi ndondomeko yomwe yatchulidwa.Kawirikawiri, mita ya magawo atatu iyenera kukhazikitsidwa motsatira ndondomeko yabwino kapena ndondomeko yofunikira.Ngati kuyika kwenikweni sikunachitike molingana ndi zofunikira, ma mita ena amphamvu omwe amasokonekera kwambiri ndi ma elekitiromu nthawi zina samachita zinthu zolemetsa, koma amatha kuchotsedwa pambuyo pokonza magawo.

Mwachidule, pamene khalidwe lopanda katundu likuchitika, sikoyenera kuyang'ana momwe mita yamagetsi ikuyendera yokha, komanso nthawi zina kuyang'ana mawaya ndi zipangizo zina za metering.
