Mphamvu yamagetsi yochokera ku madzi ndi mwala wapangodya wa mphamvu zongowonjezwdwa padziko lonse lapansi, zomwe zimapereka magetsi oyera, odalirika, komanso otsika mtengo. Komabe, kudalirika kwake kumalumikizidwa ndi kusintha kumodzi kosasinthasintha: kuyenda kwa madzi. Kumvetsetsa momwe kusintha kwa kayendedwe ka madzi kumakhudzira ndikofunikira kwambiri pakukonza bwino kupanga magetsi, kuonetsetsa kuti gridi yamagetsi ili yokhazikika, komanso kukonzekera tsogolo lolimba komanso lolimba.
Chiyerekezo Choyambira: Mphamvu, Mutu, ndi Kuyenda
Pakati pake, mphamvu zamagetsi zomwe zimachokera ku chomera chamagetsi chamadzi zimayendetsedwa ndi njira yosavuta:
P = η * ρ * g * Q * H
Kumene:
P = Mphamvu Yotulutsa
η = Kuchita Bwino Kwambiri
ρ = Kuchuluka kwa Madzi
g = Kuthamanga kwa Mphamvu yokoka
Q = Kuchuluka kwa madzi (kuchuluka kwa madzi pa sekondi)
H = Mutu (kutalika kwa madzi)
Kuchokera mu equation iyi, n'zoonekeratu kuti Flow Rate (Q) ndi njira yolunjika komanso yolunjika yopangira magetsi. Kusintha kulikonse kwa kuchuluka kwa madzi kufika pa ma turbine kumakhudza mwachangu komanso molingana magetsi opangidwa.
Mavuto Awiri a Kusintha kwa Mafunde
1. Vuto la Kuchepa kwa Madzi
Pamene madzi akuyenda pansi pa mphamvu ya kapangidwe ka chomera, mavuto angapo akuluakulu amabuka:
Kuchepa kwa Mphamvu Yotulutsa ndi Kutaya Ndalama: Uku ndiye kukhudzidwa kwachindunji kwambiri. Kutsika kwa madzi kumatanthauza madzi ochepa ozungulira ma turbine, zomwe zimapangitsa kuti kupanga magetsi kuchepe komanso kutayika kwa ndalama kwa wogwiritsa ntchito.
Kusagwira Ntchito Bwino: Turbine iliyonse imapangidwira "malo abwino kwambiri ogwirira ntchito" pamlingo winawake. Kugwira ntchito pamadzi otsika kwambiri kumakankhira turbine kunja kwa mulingo woyenera uwu, kuchepetsa kugwira ntchito kwake bwino komanso kuwonjezereka kuwonongeka ndi kung'ambika chifukwa cha kutsekeka kwa mpweya (kupanga ndi kugwa kwa thovu la mpweya, zomwe zingawononge masamba a turbine).
Mavuto Okhudzana ndi Kudzipereka kwa Ma Unit: Mu malo opangira magetsi okhala ndi mayunitsi ambiri, kutsika kwa madzi kungapangitse kuti mayunitsi opanga amodzi kapena angapo azizimitsidwe. Kusankha mayunitsi oti azigwira ntchito komanso mphamvu yanji kumakhala vuto lalikulu.
Zoletsa Zachilengedwe ndi Malamulo: Pa nthawi ya chilala, malamulo okhudza zachilengedwe nthawi zambiri amalamula kuti pakhale "madzi ochepa" kuti pakhale thanzi la zachilengedwe. Izi zimachepetsanso madzi omwe alipo kuti pakhale magetsi, zomwe zimapangitsa kuti pakhale mgwirizano pakati pa kupanga mphamvu ndi kusamalira zachilengedwe.
2. Vuto la Kuyenda Kwambiri
Ngakhale zingawoneke ngati madzi ambiri nthawi zonse amakhala abwino, madzi ambiri otuluka m'madzi amakhala ndi mavuto ake:
Kutaya Mphamvu ndi Kutaya Mphamvu: Pamene madzi olowa m'chitsime apitirira mphamvu yake kapena mphamvu yayikulu yotulutsira madzi a ma turbine, ogwiritsa ntchito ayenera "kutaya" madzi ochulukirapo pa damu. Izi zikutanthauza kutayika mwachindunji kwa mphamvu zomwe zikanasinthidwa kukhala magetsi.
Malire a Kapangidwe ka Turbine: Turbine iliyonse ili ndi liwiro lalikulu la kuyenda lomwe ingathe kuligwira bwino. Kupitirira malire amenewa kungayambitse kupsinjika kwa makina, kugwedezeka, komanso kuwonongeka kwa wothamanga ndi zigawo zina.
Mavuto Okhudza Kutaya Madzi: Zinthu zomwe zimatuluka m'madzi nthawi zambiri zimakhala ndi matope ndi zinyalala zambiri. Izi zingayambitse kusweka kwa zinthu zomwe zili pansi pa madzi ndi kutsekeka kwa zotchingira madzi, zomwe zimafuna kukonza ndi kuyeretsa kokwera mtengo.
Kusinthana ndi Njira Yoyendera Yosinthasintha
Makampani opanga magetsi pogwiritsa ntchito madzi amagwiritsa ntchito njira zingapo kuti achepetse zotsatira za kusintha kwa kayendedwe ka madzi:
Madziwe ndi Madamu: Yankho lalikulu ndi kusunga madzi. Madziwe amagwira ntchito ngati batire, amasunga madzi ambiri nthawi yamvula ndikutulutsa madzi osungidwa kuti apange nthawi yamvula. Izi zimathandiza kuti zinthu zisinthe mwachilengedwe ndikutsimikizira kuti pali magetsi odalirika.
Ukadaulo Wapamwamba wa Turbine: Kupanga ma turbine osinthika, monga Kaplan (wa mutu wotsika) ndi Francis (wa mutu wapakati-wautali), kumathandiza kuti magwiridwe antchito azisungidwa pamitundu yosiyanasiyana ya kayendedwe ka madzi. Ma turbine a Turgo (monga tafotokozera mu funso lanu lapitalo) amadziwikanso chifukwa cha magwiridwe antchito awo abwino pansi pa mikhalidwe yosinthasintha ya kayendedwe ka madzi.
Kusanthula ndi Kuneneratu za Kuneneratu: Pogwiritsa ntchito deta ya nyengo ndi zitsanzo zamadzi, ogwira ntchito amatha kulosera za kulowa kwa madzi molondola kwambiri. Izi zimathandiza kuti pakhale kasamalidwe kabwino ka madzi osungira madzi, kusankha nthawi yosungira madzi komanso nthawi yopangira madzi ambiri poyembekezera zochitika zamtsogolo zomwe zingachitike chifukwa cha kuchuluka kwa madzi kapena kuchepa kwa madzi.
Makina Ogwetsa Madzi: Makina angapo opangira magetsi pamtsinje womwewo amatha kugwiritsidwa ntchito mogwirizana. Kutulutsidwa kolamulidwa kuchokera ku chomera chakumtunda kumakhala komwe kumalowera chomera chakumunsi, zomwe zimachepetsa kusiyana kwakukulu kwa madzi pa dongosolo lonse.
Chinthu Chokhudza Kusintha kwa Nyengo
Kusintha kwa nyengo kukuwonjezera vuto la kusiyana kwa madzi. Madera ambiri akukumana ndi mavuto aakulu komanso obwerezabwereza a madzi: chilala cha nthawi yayitali komanso mvula yambiri. Izi zimapangitsa kuti deta yakale ya madzi, yomwe madamu ambiri adapangidwira, ikhale yosadalirika. Chifukwa chake, kukonzekera kwamakono kwamagetsi opangidwa ndi madzi kuyenera kuphatikiza kupirira nyengo, kupanga ndikugwiritsa ntchito zomera kuti zikhale ndi tsogolo losatsimikizika kwambiri la madzi.
Mapeto
Kusintha kwa kayendedwe ka madzi si nkhani yongoganizira chabe koma ndi nkhani yaikulu yokhudza kupanga magetsi pogwiritsa ntchito madzi. Kuyambira pa sayansi yoyambira yopanga magetsi mpaka pa zisankho zovuta zokhudzana ndi ntchito ndi chilengedwe, kuchuluka kwa madzi omwe akuyenda kudzera mufakitale kumatanthauza momwe imagwirira ntchito, zachuma, komanso kukhazikika kwake. Pogwiritsa ntchito ukadaulo wanzeru, kulosera kwapamwamba, komanso kapangidwe kosinthasintha, gawo la magetsi pogwiritsa ntchito madzi likhoza kupitiliza kuyenda m'njira zosiyanasiyana, ndikusunga gawo lake lofunikira mu gridi yamagetsi yoyera komanso yokhazikika.
