Madera a m'mapiri ali ndi mphamvu zambiri zamagetsi chifukwa cha mvula yambiri, malo otsetsereka, komanso kusiyana kwakukulu kwa mapiri. Ubwino wachilengedwewu umawapangitsa kukhala malo abwino kwambiri opangira mphamvu zamagetsi zamagetsi. Komabe, kumanga chomera chamagetsi m'mapiri kumafuna kukonzekera mosamala komanso uinjiniya kuti zitsimikizire kuti zikugwira ntchito bwino, chitetezo, komanso kukhazikika kwa chilengedwe. Kukonzekera bwino kumaphatikizapo masitepe angapo ofunikira, kuyambira kuwunika zinthu mpaka kusankha zida ndi kuyang'anira chilengedwe.
1. Chitani kafukufuku wa madzi
Gawo loyamba pokonzekera malo opangira magetsi a m'mapiri ndikuphunzira za madzi am'deralo. Mainjiniya ayenera kusanthula deta ya nthawi yayitali yamadzi, kuphatikizapo kuyenda kwa mitsinje, kusintha kwa nyengo, kuchuluka kwa kusefukira kwa madzi, ndi chilala. M'madera amapiri, kuyenda kwa madzi kumatha kusintha kwambiri pakati pa nyengo yamvula ndi youma.
Mwa kusonkhanitsa ndi kusanthula deta yamadzi, okonza mapulani amatha kudziwa momwe kapangidwe kake kakuyendera, mphamvu yoyikidwa, komanso kuchuluka kwa magetsi omwe angapangidwe pachaka pafakitale yamagetsi. Chidziwitsochi chimapanga maziko a kapangidwe ka uinjiniya kamene kadzachitika pambuyo pake.
2. Sankhani Malo Oyenera
Kusankha malo ndi chimodzi mwa zinthu zofunika kwambiri pakukula kwa magetsi opangidwa ndi madzi. M'mapiri, okonza mapulani nthawi zambiri amafufuza malo okhala ndi malo akuluakulu achilengedwe (hydraulic head) komanso malo okhazikika a geology.
Malo abwino ayenera kukhala ndi:
Kuyenda bwino kwa madzi chaka chonse
Kusiyana kokwanira kwa kukwera kuti apange mphamvu moyenera
Mapangidwe a miyala yolimba kuti amange bwino
Malo osavuta opezera zomangira ndi zida zoyendera
Malo osankhidwa bwino angachepetse kwambiri ndalama zomangira ndikuwonjezera kudalirika kwa malo opangira magetsi amadzi kwa nthawi yayitali.
3. Dziwani Ndondomeko Yachitukuko
Akasankha malo, mainjiniya ayenera kusankha njira yoyenera kwambiri yopangira magetsi amadzi. M'madera amapiri, njira zodziwika kwambiri zimaphatikizapo:
Machitidwe oyendera mitsinje - Mitengo iyi imagwiritsa ntchito madzi achilengedwe a mtsinje popanda kusunga madzi ambiri kapena osasunga madzi. Sizikhudza chilengedwe kwenikweni ndipo zimagwiritsidwa ntchito kwambiri pa ntchito zazing'ono komanso zapakatikati zamagetsi.
Malo opangira magetsi amadzi okhala ndi mtundu wosiyana - Madzi amachotsedwa mumtsinje kudzera mu ngalande kapena ngalande kupita ku malo opangira magetsi omwe ali pamalo otsika. Kapangidwe kameneka kamagwiritsa ntchito bwino kusiyana kwachilengedwe kwa mitu m'madera amapiri.
Zomera zamtundu wa chimbudzi - Zomerazi zimasunga madzi kumbuyo kwa damu, zomwe zimathandiza kuti madzi aziyenda bwino komanso kuti magetsi aziyenda bwino.
Pakati pa njira zimenezi, njira zosinthira madzi ndizoyenera kwambiri m'madera amapiri chifukwa zimatha kugwira ntchito bwino popanda kufunikira madamu akuluakulu.
4. Sankhani Zida Zoyenera Zopangira Turbine
Kusankha turbine yoyenera ndikofunikira kuti pakhale kugwira ntchito bwino komanso kodalirika. Mtundu wa turbine umadalira makamaka mutu womwe ulipo komanso madzi omwe akuyenda.
Ma turbine a Pelton amagwiritsidwa ntchito kwambiri m'mapulojekiti amphamvu amadzi okhala ndi mapiri okwera kwambiri omwe ali ndi mphamvu zochepa zoyendera madzi.
Ma turbine a Francis ndi oyenera kugwiritsa ntchito mphamvu yapakati komanso yapakati.
Ma turbine a Kaplan kapena ma tubular nthawi zambiri amagwiritsidwa ntchito pamalo otsika.
Kusankha bwino turbine kumatsimikizira kuti mphamvu yosinthira mphamvu imagwira ntchito bwino kwambiri komanso kuti igwire ntchito bwino kwa nthawi yayitali.
5. Kupanga Kapangidwe ka Ma Hydropower Key
Dongosolo lonse lamagetsi amadzi m'mapiri nthawi zambiri limakhala ndi zinthu zingapo zofunika:
Kapangidwe ka chakudya cholowa
Beseni lochotsamo matope kapena thanki lokhazikitsira
Njira yotumizira madzi (njira, mapaipi, kapena ngalande)
Tanki ya Forebay kapena thanki yoyendera
Penstock
Makina opangira magetsi ndi jenereta
Njira ya Tailrace
Chigawo chilichonse chiyenera kupangidwa mosamala kuti chithandize kuyenda bwino kwa madzi, kuchepetsa kutayika kwa mphamvu, komanso kuti chizigwira ntchito bwino.
6. Konzani Zomanga ndi Mayendedwe
Madera a m'mapiri nthawi zambiri amakhala ndi mavuto okhudzana ndi kayendetsedwe ka zinthu. Misewu, milatho, ndi zomangamanga kwakanthawi zingafunike kumangidwa ntchito isanayambe. Zipangizo zolemera monga ma turbine, ma jenereta, ndi ma transformer ziyenera kunyamulidwa mosamala kupita kumalo akutali a ntchito.
Kukonzekera bwino ntchito yomanga kungachepetse kuchedwa kwa ntchito ndikuwongolera ndalama zonse.
7. Ganizirani za Kuteteza Chilengedwe
Kuteteza chilengedwe ndi gawo lofunika kwambiri pa chitukuko chamakono cha magetsi opangidwa ndi madzi. Okonza mapulani ayenera kuwunika momwe polojekitiyi ingakhudzire zachilengedwe ndi madera am'deralo.
Njira zazikulu zotetezera chilengedwe zingaphatikizepo izi:
Kusunga kayendedwe ka zachilengedwe mumtsinje
Kuteteza zamoyo zam'madzi ndi njira zosamukira nsomba
Kulamulira kutayikira kwa nthaka ndi kukokoloka kwa nthaka
Kuchepetsa kuwonongeka kwa zomera panthawi yomanga
Mwa kuphatikiza zinthu zokhudzana ndi chilengedwe mu njira yopangira mapulani, mapulojekiti amagetsi opangidwa ndi madzi amatha kukwaniritsa chitukuko chokhazikika.
Kukonzekera malo opangira magetsi pogwiritsa ntchito madzi m'mapiri kumafuna njira yokwanira yomwe imaphatikizapo kusanthula kwa madzi, kapangidwe ka uinjiniya, kusankha zida, ndi kuteteza chilengedwe. Ngati akukonzekera bwino ndikukhazikitsidwa, mapulojekiti opangira magetsi pogwiritsa ntchito madzi m'mapiri amatha kupereka mphamvu yodalirika yongowonjezedwanso, kuthandizira chitukuko cha zachuma m'deralo, komanso kuthandizira pakuyesetsa padziko lonse kuchepetsa mpweya woipa wa carbon.
