Kupanga Mphamvu ya Mafunde mu Mphamvu Yongowonjezedwanso
Mphamvu zongowonjezedwanso ndi chinthu chofunikira kwambiri pothana ndi mavuto a kusintha kwa nyengo, kufunikira kwa magetsi ambiri, komanso kuchepa kwa mafuta opangidwa ndi zinthu zakale. Makambirano okhudza mphamvu zongowonjezedwanso nthawi zambiri amayang'ana kwambiri mphamvu ya dzuwa, mphepo, madzi, ndi kutentha kwa dziko. Komabe, gwero limodzi la mphamvu lili ndi kuthekera kwakukulu, makamaka kwa dziko lozungulira ngati Indonesia: mphamvu ya mafunde a m'nyanja. Zomera Zamagetsi a Mafunde (PLTGL) zimagwiritsa ntchito kayendedwe ka mafunde a m'nyanja kuti ziwasinthe kukhala mphamvu zamagetsi kuti anthu ndi mafakitale azigwiritsa ntchito. Nkhaniyi ikufotokoza za lingaliro, ukadaulo, ubwino, zovuta, ndi chiyembekezo cha PLTGL m'malo opangira mphamvu zongowonjezedwanso.
Mphamvu ya Mafunde a Nyanja
Mafunde a m'nyanja amapangidwa ndi kusamutsa mphamvu kuchokera ku mphepo kupita pamwamba pa nyanja. Mphepo ikakhala yamphamvu komanso ikakhala yayitali, mphamvu ya mafunde imapangidwanso kwambiri. Mphamvu ya mafunde ili ndi ubwino kuposa magwero ena obwezerezedwanso chifukwa chakuti ndi yokhazikika komanso yodziwikiratu kuposa mphepo kapena kuwala kwa dzuwa nthawi iliyonse. M'madera ambiri a m'mphepete mwa nyanja ndi nyanja yotseguka, mafunde amatha kupezeka pafupifupi chaka chonse ndi mphamvu yayikulu.
Indonesia, yokhala ndi gombe lalikulu komanso malo ake pakati pa nyanja za Indian ndi Pacific, ili ndi kuthekera kwakukulu kwa mphamvu ya mafunde. Madera akum'mwera kwa Java, Bali, Nusa Tenggara, ndi madera ena a Maluku ndi Papua amadziwika ndi mafunde amphamvu, makamaka nthawi zina za mphepo. Ngati itayendetsedwa bwino, mphamvu ya mafunde ingathandize kuyika magetsi m'madera a m'mphepete mwa nyanja ndi zilumba zazing'ono zomwe pakali pano zimadalira dizilo.
Momwe Zomera Zamagetsi Zamagetsi Zimagwirira Ntchito
Mfundo yaikulu ya chomera chamagetsi chamagetsi chogwiritsa ntchito mpweya (PLTGL) ndikusintha mphamvu yamakina ya mafunde kukhala mphamvu yamagetsi. Mafunde amapanga mayendedwe obwerera ndi kubwerera, mmwamba ndi pansi, kapena kusintha kwa kuthamanga kwa madzi. Kenako mayendedwe amenewa amagwiritsidwa ntchito kuyendetsa makina monga ma turbine, ma pistoni, kapena majenereta olunjika. Magetsi omwe amatuluka amalunjika ku makina osinthira mphamvu, kukhazikika, kenako amagawidwa ku gridi yamagetsi ya m'mphepete mwa nyanja kapena kugwiritsidwa ntchito kwanuko.
Kawirikawiri, makina opangira magetsi oyendetsedwa ndi gasi (PLTGL) amakhala ndi zigawo zikuluzikulu zingapo: makina ogwiritsira ntchito mphamvu (converter), makina otumizira magetsi omwe amasintha kayendedwe kukhala mphamvu yozungulira/kuzungulira, jenereta, ndi zida zoziziritsira magetsi, komanso zingwe zam'madzi kuti zitumize magetsi kumtunda. Kugwira ntchito kwa makina opangira magetsi kumadalira kwambiri kapangidwe ka zida, momwe mafunde amayendera, kuya kwa madzi, ndi njira zogwirira ntchito ndi kukonza.
Mitundu ya Ukadaulo wa PLTGL
Ukadaulo wa mafunde a m'nyanja ukupita patsogolo mofulumira ndipo uli ndi mitundu yosiyanasiyana. Mitundu ina yodziwika bwino ndi iyi:
1. Chokolera Mfundo
Chida ichi nthawi zambiri chimakhala ngati choyandama chomwe chimayenda mmwamba ndi pansi chikutsatira mafunde. Kuyenda koyima kwa choyandama kumasinthidwa kukhala magetsi kudzera mu jenereta kapena makina olumikizirana Ubwino wake ndi kapangidwe kake kofanana ndi kamene kali ndi kuthekera koyikidwa mochuluka ngati "famu ya mafunde."
2. Mzati wa Madzi Ozungulira (OWC)
Ukadaulo wa OWC umagwiritsa ntchito mpweya womwe uli m'chipinda cholumikizidwa ndi nyanja. Mafunde akalowa, madzi amakwera, kukanikiza mpweya ndikuukakamiza kudutsa mu turbine. Mafunde akachepa, mpweya umabwerera mkati ndi kudzera mu turbine. Ma turbine omwe amagwiritsidwa ntchito nthawi zambiri amakhala ma turbine apadera (monga ma Wells turbine) omwe amatha kuzungulira mbali ziwiri.
3. Chochepetsera
Ichi ndi chipangizo chachitali chomwe chimayikidwa motsatira njira ya mafunde. Mafundewa amachititsa kuti chipangizocho chizigwedezeka pamalo ena, kenako kayendedwe kake kamasanduka mphamvu kudzera mu dongosolo la hydraulic ndi jenereta. Lingaliro ili ndi loyenera mafunde otseguka a nyanja okhala ndi mphamvu zambiri.
4. Chipangizo Chowonjezera Mphamvu
Dongosololi limagwiritsa ntchito mafunde "kuthira" madzi m'chitsime chapamwamba, mofanana ndi mfundo ya mini-dam. Madzi osonkhanitsidwawo amabwerera kudzera mu turbine yamadzi kuti apange magetsi. Ubwino wake ndi mphamvu yokhazikika yotulutsa madzi chifukwa cha chitsimecho, koma chimafuna kapangidwe kake kakang'ono.
Ukadaulo uliwonse uli ndi ubwino ndi zofooka zake. Kusankha zida kuyenera kusinthidwa kuti kugwirizane ndi mawonekedwe a mafunde am'deralo, zofunikira pa mphamvu, kuya ndi mawonekedwe a pansi pa nyanja, komanso ndalama zomangira.
Ubwino wa Magetsi Ogwiritsa Ntchito Gasi Pakusintha kwa Mphamvu
Malo opangira magetsi pogwiritsa ntchito gasi (PLTGL) amapereka maubwino angapo. Choyamba, ndi gwero la mphamvu loyera ndipo silitulutsa mpweya woipa wa carbon panthawi yogwira ntchito. Chachiwiri, mphamvu ya mafunde imatha kuwonjezera mphamvu ya dzuwa ndi mphepo yomwe imagwira ntchito nthawi ndi nthawi. M'malo ena, mafunde amatha kukhala okhazikika usiku kapena nthawi ya mitambo, zomwe zimathandiza kukhazikika kwa mphamvu yongowonjezwdwanso.
Chachitatu, malo opangira magetsi pogwiritsa ntchito gasi (PLTGL) angathandize kuti zilumba zazing'ono zizikhala ndi mphamvu zokha. Zilumba zambiri zakutali zimadalirabe majenereta a dizilo okwera mtengo komanso oipitsa, omwe amafunikira mafuta osakhazikika. Ndi PLTGL, magetsi amatha kupangidwa pafupi ndi momwe amagwiritsidwira ntchito. Chachinayi, chitukuko cha makampani opanga magetsi pogwiritsa ntchito gasi chimatsegulanso mwayi wofufuza, kupanga zatsopano pazaukadaulo wapamadzi, ndi ntchito zatsopano pa ntchito zomanga, ntchito, ndi kukonza.
Zovuta ndi Zopinga pa Chitukuko
Ngakhale kuti malo opangira magetsi opangidwa ndi gasi (PLTGL) akukumana ndi mavuto akuluakulu. Chimodzi mwa zinthu zomwe zimawononga ndalama zambiri. Malo okhala m'nyanja ndi owononga, osinthasintha, komanso oopsa kwambiri. Zipangizo ziyenera kupirira mphepo yamkuntho, mafunde akuluakulu, ndi biofouling (kulumikizana kwa zamoyo zam'madzi), zomwe zingawononge magwiridwe antchito. Kuphatikiza apo, ntchito ndi kukonza zinthu m'nyanja ndizovuta komanso zodula kuposa malo opangira magetsi am'nyanja.
Vuto lina ndi kuphatikizidwa mu gridi yamagetsi. Malo ambiri okhala ndi mafunde amphamvu ali kutali ndi malo olowetsa katundu ndipo mwina sakhala ndi zomangamanga zokwanira za netiweki. Ma waya apansi pa nyanja, malo osungiramo zinthu, ndi machitidwe odalirika oyendetsera magetsi amafunika. Malinga ndi malamulo, chitukuko m'madera a m'mphepete mwa nyanja ndi m'nyanja chimafunanso mgwirizano pakati pa magawo osiyanasiyana, kuphatikizapo omwe akukhudza usodzi, zombo zonyamula katundu, kusungirako zinthu, ndi kukonzekera malo a m'nyanja.
Zotsatira za chilengedwe ziyenera kuganiziridwa mozama. Ngakhale kuti ndi zoyera kuposa mafuta oyeretsera, magetsi opangidwa ndi gasi (PLTGL) amatha kukhudza malo okhala m'nyanja, njira zosungiramo madzi m'deralo, kapena njira zosamukira za mitundu ina ya zamoyo. Chifukwa chake, maphunziro owunikira momwe chilengedwe chimakhudzira (EIA), kuyang'anira zachilengedwe, komanso kapangidwe kosamalira chilengedwe ndizofunikira kwambiri kuti zigwiritsidwe ntchito.
Ziyembekezo za Malo Opangira Magetsi Ogwiritsa Ntchito Gasi ku Indonesia
Indonesia ili ndi zinthu zambiri zopangira magetsi opangidwa ndi gasi (PLTGL): gombe lalitali, madera ambiri okhala ndi mafunde okwanira, komanso kufunikira kwa magetsi ndi mphamvu zoyera kukukulirakulira. Chitukuko chingayambe kudzera mu mapulojekiti ang'onoang'ono mpaka apakati m'malo ofunikira kwambiri, monga gombe la kum'mwera kwa Java kapena zilumba zazing'ono zomwe zimadalirabe dizilo. Njira imeneyi imathandiza kuyesa kudalirika kwa ukadaulo, kukhazikitsa miyezo yachitetezo, ndikumanga mphamvu za anthu am'deralo.
Mgwirizano pakati pa boma, mayunivesite, mabungwe ofufuza, ndi mafakitale ndi wofunikira. Boma limagwira ntchito yopereka malamulo omveka bwino, njira zolimbikitsira, komanso thandizo loyamba la ndalama. Magawo a maphunziro ndi kafukufuku amatha kupanga mapangidwe oyenerana ndi mawonekedwe a madzi aku Indonesia, kuphatikiza zipangizo zosagwira dzimbiri ndi makina otetezeka omangira. Makampani amatha kufulumizitsa kupanga, kukhazikitsa, ndi kugulitsa.
Mtsogolomu, PLTGL ikhozanso kuphatikizidwa ndi magetsi ena, monga dzuwa ndi mabatire, kupanga njira yosakanikirana kuti iwonjezere kudalirika kwa magetsi. Kuphatikiza apo, magetsi a mafunde angagwiritsidwe ntchito pazinthu zapadera monga kuchotsa mchere m'madzi a m'nyanja, kupanga haidrojeni wobiriwira, kapena madoko othandizira ndi malo ogwirira ntchito m'mphepete mwa nyanja.
Mapeto
Kupanga mphamvu zamagetsi pogwiritsa ntchito mafunde ndi njira yokongola kwambiri yowonjezerera mphamvu, makamaka kwa mayiko a m'nyanja. Pogwiritsa ntchito mphamvu zambiri zamagetsi pogwiritsa ntchito mafunde, zomera zamagetsi pogwiritsa ntchito mafunde (PLTGL) zingathandize kuchepetsa kudalira mafuta ochokera ku zinthu zakale, kuchepetsa mpweya woipa, komanso kulimbitsa mphamvu zodziyimira pawokha m'madera a m'mphepete mwa nyanja ndi zilumba zakutali. Komabe, chitukuko chawo chimafuna ndalama zambiri, ukadaulo wokhazikika panyanja, malamulo othandizira, komanso kuwunika bwino zachilengedwe. Ngati zigwiritsidwa ntchito pang'onopang'ono komanso mogwirizana, zomera zamagetsi pogwiritsa ntchito mafunde zimatha kukhala gawo lofunika kwambiri la tsogolo la mphamvu zoyera ku Indonesia.
