Zinthu ndi Zochitika zaMphamvu mita's No-load Behaviour

Pamene mita ya mphamvu ikugwira ntchito, zinthu ziwiri ziyenera kukwaniritsidwa.(1) Sipayenera kukhala pakali pano pamayendedwe apano a mita yamagetsi;(2) mita yamagetsi sayenera kutulutsa mphamvu yoposa imodzi.

Khalidwe lopanda katundu wa mita ya mphamvu lingadziwike kokha ngati zinthu ziwiri zomwe zili pamwambazi zakwaniritsidwa nthawi imodzi.Ngati khalidwe lopanda katundu limayambitsa kupitirira 115% yamagetsi owonetserako, malinga ndi malamulo oyenerera, mita yamagetsi ndi yoyenerera, yomwe siingakhoze kuonedwa 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 ku mita yayikulu 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 kutulutsa mphamvu yopitilira imodzi

Pambuyo poonetsetsa kuti palibe panopa pa dera lamakono la mita ya magetsi, zikhoza kudziwika ngati palibe katundu wamtundu kapena ayi kutengera ngati kuwala kwa pulse kukuwalira kapena ayi.Kutulutsa koyesa kwa mita sikukhala ndi kugunda kumodzi.

Mukatsimikizira kuti palibe katundu, lembani nthawi t(mphindi) ya kugunda kulikonse ndi c(r/kWh) yosalekeza ya mita yamagetsi, ndipo bwezerani 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.

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.
