Pakadali pano, ma jenereta a dizilo amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndipo ndi zida zamagetsi zomwe amakonda popereka mphamvu zosunga zobwezeretsera ngati magetsi azimitsidwa mwadzidzidzi kapena kugwiritsa ntchito magetsi tsiku lililonse ndi mabizinesi.Majenereta a dizilo amagwiritsidwanso ntchito kwambiri kumadera akumidzi kapena kumunda.Chifukwa chake, musanagule jenereta ya dizilo, kuti muwonetsetse kuti jeneretayo imatha kupereka magetsi abwino kwambiri, ndikofunikira kumvetsetsa bwino za kilowatts (kW), kilovolt amperes (kVA), ndi mphamvu (PF) The kusiyana pakati pawo ndikofunikira:
Kilowatt (kW) amagwiritsidwa ntchito kuyeza magetsi enieni operekedwa ndi ma jenereta, omwe amagwiritsidwa ntchito mwachindunji ndi zipangizo zamagetsi ndi zipangizo zanyumba.
Yezerani mphamvu yowoneka mu kilovolt amperes (kVA).Izi zikuphatikiza mphamvu yogwira ntchito (kW), komanso reactive power (kVAR) yogwiritsidwa ntchito ndi zida monga ma mota ndi ma transformer.Mphamvu yogwira ntchito siidyedwa, koma imazungulira pakati pa gwero la mphamvu ndi katundu.
Mphamvu yamagetsi ndi chiŵerengero cha mphamvu yogwira ntchito ku mphamvu yowonekera.Ngati nyumbayo imagwiritsa ntchito 900kW ndi 1000kVA, mphamvu yamagetsi ndi 0.90 kapena 90%.
Nambala ya jenereta ya dizilo idavotera kW, kVA, ndi PF.Kuti muwonetsetse kuti mutha kusankha jenereta yoyenera kwambiri ya dizilo, lingaliro labwino kwambiri ndikufunsa katswiri wamagetsi kuti adziwe kukula kwa setiyo.
Kuchuluka kwa kilowatt kutulutsa kwa jenereta kumatsimikiziridwa ndi injini ya dizilo yomwe imayendetsa.Mwachitsanzo, taganizirani jenereta yoyendetsedwa ndi injini ya dizilo ya 1000 ndiyamphamvu yokhala ndi mphamvu ya 95%:
1000 ndiyamphamvu ndi yofanana ndi 745.7 kilowatts, yomwe ndi mphamvu ya shaft yoperekedwa kwa jenereta.
Mwachangu 95%, pazipita linanena bungwe mphamvu 708.4kW
Komano, pazipita kilovolt ampere zimadalira voteji oveteredwa ndi panopa wa jenereta.Pali njira ziwiri zowonjezeretsa jenereta:
Ngati katundu wolumikizidwa ndi jenereta ukuposa kilowatts oveteredwa, idzadzaza injini.
Kumbali ina, ngati katunduyo aposa kVA oveteredwa, adzadzaza mafunde a jenereta.
Ndikofunika kukumbukira izi, chifukwa ngakhale katundu wa kilowatts ali pansi pa mtengo wovotera, jenereta ikhoza kudzaza mu kilovolt amperes.
Ngati nyumbayo imadya 1000kW ndi 1100kVA, mphamvu yamagetsi idzawonjezeka kufika 91%, koma sichidzapitirira mphamvu ya jenereta.
Komano, ngati jenereta imagwira ntchito pa 1100kW ndi 1250kVA, mphamvu yamagetsi imangowonjezera mpaka 88%, koma injini ya dizilo imadzaza.
Majenereta a dizilo amathanso kudzaza ndi kVA yokha.Ngati zida zikugwira ntchito pa 950kW ndi 1300kVA (73% PF), ngakhale injini ya dizilo itakhala yosadzaza, ma windings adzakhalabe odzaza.
Mwachidule, ma jenereta a dizilo amatha kupitilira mphamvu zawo zovoteledwa popanda vuto lililonse, bola ngati kW ndi kVA zikukhalabe pansi pamitengo yawo.Sitikulimbikitsidwa kugwira ntchito pansi pa PF yomwe idavotera, chifukwa magwiridwe antchito a jenereta ndi otsika.Pomaliza, kupitilira muyeso wa kW kapena ma kVA kungawononge zida.
Momwe Mphamvu Zotsogola ndi Zotsalira Zimakhudzira Majenereta a Dizilo
Ngati kukana kokha kumalumikizidwa ndi jenereta ndi voteji ndipo zapano zikuyezedwa, mawonekedwe awo a AC amafanana akawonetsedwa pa chida cha digito.Zizindikiro ziwiri zimasinthana pakati pa zabwino ndi zoipa, koma zimadutsa 0V ndi 0A nthawi imodzi.Mwa kuyankhula kwina, magetsi ndi magetsi ali mu gawo.
Pankhaniyi, mphamvu ya katunduyo ndi 1.0 kapena 100%.Komabe, mphamvu yamagetsi yamagetsi ambiri m'nyumba si 100%, zomwe zikutanthauza kuti magetsi awo ndi apano azithetsana:
Ngati nsonga ya AC voteji imatsogolera pachimake chapano, katunduyo amakhala ndi mphamvu yotsalira.Katundu wokhala ndi khalidweli amatchedwa inductive loads, yomwe imaphatikizapo ma motors amagetsi ndi ma transformer.
Kumbali ina, ngati pakali pano amatsogolera voteji, katundu ali ndi kutsogolera mphamvu factor.Katundu wokhala ndi izi amatchedwa capacitive load, yomwe imaphatikizapo mabatire, mabanki a capacitor, ndi zida zina zamagetsi.
Nyumba zambiri zimakhala ndi zolemetsa zambiri kuposa zonyamula capacitive.Izi zikutanthauza kuti mphamvu yonse yamagetsi nthawi zambiri imakhala yotsalira, ndipo seti ya jenereta ya dizilo imapangidwa makamaka pamtundu woterewu.Komabe, ngati nyumbayo ili ndi katundu wambiri wa capacitive, mwiniwakeyo ayenera kusamala chifukwa magetsi a jenereta adzakhala osakhazikika pamene mphamvu yamagetsi ikupita patsogolo.Izi zidzayambitsa chitetezo chodziwikiratu, kuchotsa chipangizocho kuchokera mnyumbamo.
