Zvivakwa zveMagetsi eGasi muMasisitimu eMagetsi
Chigayo chemagetsi chinoshandisa gasi (PLTG) imhando yechigayo chemagetsi chinoshandisa simba rinobva mukupiswa kwegasi—kazhinji gasi rechisikigo—kugadzira magetsi. Mumasisitimu emagetsi emazuva ano, maPLTG anoita basa rakakosha nekuti anoshanda zviri nyore, anopindura nekukurumidza kune shanduko mumutoro, uye anogona kutsigira kuvimbika kwesisitimu kana mamwe masosi esimba achichinja-chinja. Munyika dzakawanda, kusanganisira Indonesia, maPLTG chikamu chemusanganiswa wesimba une chinangwa chekusangana nekuwanda kwekuda kwemagetsi uku uchichengetedza kugadzikana kwegrid.
Nheyo yekushanda yeGas Turbine Power Plant
Kazhinji, chigayo chemagetsi chinoshandisa gasi chinoshanda paBrayton cycle. Mhepo inobva mumhepo inokweverwa mukati uye inomanikidzwa necompressor, zvichiwedzera kumanikidzwa kwayo. Mhepo inomanikidzwa inobva yapinda mukamuri rinopisa, uko mafuta egasi anopinzwa uye anopiswa. Gasi rinopisa, rinopisa, rine kumanikidzwa kwakanyanya, rinoyerera nepaturbine yegasi, richitenderedza mashizha eturbine uye richigadzira simba remuchina. Simba iri remuchina rinozosunda jenareta kuti igadzire magetsi.
Chimwe chezvinhu zvikuru zvinoitwa nematurbine egasi kugona kwawo kusvika pakushanda kwenguva pfupi zvichienzaniswa nemaplanti emagetsi anogadzirwa nemhepo (akadai semaplanti emagetsi anofambiswa nemarasha). Izvi zvinoita kuti maturbine egasi akwanise kushandiswa zvakanyanya kana kuti semaplanti emagetsi anotevera mutoro kana paine shanduko dzinokurumidza mukudiwa kwemagetsi.
Basa reGas Turbine Power Plants muSistimu yeMagetsi
Muhurongwa hwemagetsi, majenareta haana basa rekugadzira simba chete asiwo rekuchengetedza kugadzikana kwema frequency, kugadzikana kwevoltage, uye kuvimbika kwemagetsi. Zvivakwa zvemagetsi zvinoshandisa gasi zvinowanzo shandiswa mabasa akakosha, anosanganisira:
1. Jenareta yePeak Load (Peaker)
Nekuda kwekutanga kwayo nekukurumidza, mafekitori emagetsi anoshandisa gasi akanakira kusangana nekuwedzera kwesimba remagetsi panguva dzakati wandei, senge husiku apo kushandiswa kwemagetsi emumba kunowedzera kana kuti kana mabasa emaindasitiri akanyanya.
2. Simba Rinodzokororwa
Majenareta esimba rinodzokororwa akadai semagetsi ezuva nemhepo anogara achichinja-chinja, achivimba nezuva nemhepo. Majenareta esimba rinoshandisa gasi anogona kushanda semajenareta ekutsigira, achikurumidza kuvhura kana simba rinodzokororwa rikadonha, zvichichengetedza kugadzikana kwesystem.
3. Kudzora Mafambiro Enguva uye Kutenderera Kwenguva
Mafambiro emagetsi emagetsi anofanira kuchengetedzwa akaenzana nenhamba yepamusoro (semuenzaniso, 50 Hz). Kana paine nyonganyonga kana shanduko yemutoro kamwe kamwe, chiteshi chemagetsi chinoshandisa gasi chinogona kukwira kana kudzika nekukurumidza kuti chirambe chichienderera mberi.
4. Kuvimbika Kwemasisitimu Uye Kudzoreredza Kukanganiswa
Mamwe mafekitori emagetsi anoshandisa gasi anogona kushandiswa kutanga magetsi nemagetsi matema, izvo zvinoita kuti jenareta itange kushanda pasina magetsi kubva pagrid, zvichiita kuti hurongwa hudzoke nekukurumidza mushure mekudzima magetsi zvachose.
Rudzi rweKugadzika: Simple Gas Turbine uye Combined Cycle Power Plant
Mukuita, zviteshi zvemagetsi zvinoshandisa gasi zvinogona kuuya muzvikamu zviviri zvikuru:
- Chiteshi cheSimple Cycle Gas Turbine Power Plant
Kushandisa turbine nejenareta yegesi chete. Zvakanakira zvinosanganisira dhizaini iri nyore, mari shoma yekudyara, uye mhinduro yekukurumidza yekushanda. Zvisinei, kushanda zvakanaka kunowanzova kwakaderera nekuti kupisa kwemhepo kubva muturbine hakushandiswi.
- Chiteshi chemagetsi cheCombined Cycle Gas and Steam (PLTGU)
Kupisa kwemhepo kunobva mugasi remagetsi kunoshandiswa kudziisa mvura muHeat Recovery Steam Generator (HRSG), ichigadzira utsi hunozofambisa imwe turbine yemhepo. Kugadziriswa uku kunovandudza kushanda zvakanaka nekuti simba rekupisa raimboshandiswa kare rinoshandiswazve kugadzira magetsi. Mumagetsi, macombined cycle power plants (CCPPs) anowanzo shandiswa semajenareta ane mutoro wepakati kusvika pasi nekuda kwekushanda kwawo kwakanyanya.
Mabhenefiti ePLTG
Zvivakwa zvemagetsi zvinoshandisa gasi zvine zvakanakira zvakawanda zvinoita kuti zvive zvine hungwaru muhurongwa hwemagetsi, zvinosanganisira:
1. Mhinduro Yekukurumidza Yekushanda
Nguva yekutanga nekukurumidza uye kugona kushandura magetsi zvinoita kuti mafekitori emagetsi anoshandisa gasi ave akavimbika kune zvinodiwa nesystem flexible.
2. Kubuda Kwemhepo Kushoma Pane Marasha
Zvichienzaniswa nemagetsi anoshandiswa nemarasha, kupisa gasi kunoburitsa CO₂ shoma uye tunhu tunosvibisa. Izvi zvinotsigira kuedza kuderedza kusvibiswa, kunyangwe zvichiri mafuta ekare.
3. Nzvimbo Diki Yenzvimbo
Zvivakwa zvematurbine egasi zvinowanzoda ivhu shoma pane zvimwe zvirimwa zvine simba rakaenzana.
4. Yakakodzera Masisitimu Emagetsi Anochinja
Nekuwedzera kwekupinda kwesimba rinogona kushandiswazve, kudiwa kwekugadzira simba rinochinjika kuri kuwedzera. Zvivakwa zvemagetsi zvinoshandisa gasi (PLTG) zvinogona kushanda se "bhiriji" rekuchinja kwesimba ukuwo matekinoroji ekuchengetedza simba (akadai semabhatiri makuru) achizodhura zvishoma.
Matambudziko Nekuganhurirwa
Kunyangwe iine mabhenefiti akawanda, PLTG inosanganawo nematambudziko akati wandei:
1. Kuvimba neKuwanikwa kweGasi
Kushanda kwezviteshi zvemagetsi zvinoshandisa gasi (PLTG) kunoenderana zvikuru nekuwanikwa uye kuvimbika kwezvivakwa zvegasi (mapaipi, LNG, uye nzvimbo dzekugadzirisa gasi). Kukanganiswa kwemagetsi kunogona kukanganisa kugadzirwa kwemagetsi zvakananga.
2. Kuchinja-chinja kwemitengo yemafuta
Mitengo yepeturu inogona kuchinja-chinja zvichienderana nemisika yemagetsi yepasi rose, zvichiita kuti mitengo yekugadzira magetsi isagadzikane kana pasina zvibvumirano zvakasimba zvekupa magetsi kwenguva refu.
3. Kushanda Nesimba Repasi Rekutenderera
Zvivakwa zvemagetsi zvinoshandisa gasi zviri nyore zvinowanzoshanda zvishoma pane zvivakwa zvemagetsi zvinoshandisa mavhiri akabatana. Kana zvikashandiswa nguva dzose semutoro wekutanga, mitengo yemafuta pa kWh inogona kukwira.
4. Matambudziko eMethane Emission muSupply Chain
Kunyangwe gasi richitsva rakachena kupfuura marasha, kudonha kwemethane mukugadzirwa nekuparadzirwa kwegasi kunogona kuwedzera kukanganisa nharaunda nekuti methane igesi ine simba rinopisa greenhouse.
Kubatanidzwa kweGas Turbine Power Plant neMashandiro eSistimu yeMagetsi
Mukushanda kwemagetsi, vanofambisa magetsi vanoongorora hupfumi nehunyanzvi pavanenge vachisarudza kuti ndeapi mayuniti anogadzira magetsi anofanira kushanda. Kuronga mayuniti anogadzira magetsi (kuzvipira kweyuniti uye kutumira magetsi) kunofunga nezvemitengo yemafuta, miganhu yekukwira, nguva yekutanga, miganhu yekushanda, uye zvinodiwa zvekuchengetedza. Zviteshi zvemagetsi zvinofambiswa negasi zvinowanzoiswa kuti zvitsigire nzvimbo dzine mitoro inochinja nekukurumidza, simba rinogona kushandiswazve, kana senzira yekuchengetedza kana mamwe mayuniti anogadzira magetsi akadzimwa.
Pamusoro pezvo, mafekitori emagetsi anoshandiswa negasi anofanirawo kuzadzisa mitemo yegrid code, kusanganisira kugona kudzora voltage kuburikidza nejenareta excitation system, kugona kutsungirira kusagadzikana kwevoltage kwechinguva (fault ride-through), uye kupindura kushanduko kwema frequency.
Tarisiro Yeramangwana Yezviteshi Zvemagetsi Egasi
Zvichienderera mberi, mafekitori emagetsi anoshandisa gasi (PLTG) anotarisirwa kuramba akakosha, kunyanya semajenareta anochinjika kuti awedzere simba rinogona kushandiswazve. Zvisinei, mirayiridzo yemutemo wesimba netekinoroji iri kukurudzirawo mafekitori emagetsi anoshandisa gasi kuti ave nemhepo shoma, semuenzaniso kuburikidza nekuwedzera kushanda zvakanaka kwemafekitori emagetsi akabatana (CCS), kushandiswa kwetekinoroji yekubata kabhoni (CCS) pachiyero, uye kushandiswa kwehydrogen blending mumaturbine egasi anoenderana.
Nehurongwa hwakakodzera—kubva pakusimbisa zvivakwa zvegasi, kuwedzera kushanda zvakanaka, kusvika pakugadzirisa kuburitswa kwemhepo—zvigadziko zvemagetsi zvinoshandisa gasi zvinogona kuva chinhu chakakosha muhurongwa hwemagetsi hwakavimbika uye hwakachena, ukuwo zvichibatanidza shanduko kuenda kuhurongwa hwemagetsi hunochengetedza nguva.
-
Kana muchida, ndinogona kugadzirisa chinyorwa ichi kuita shanduro yedzidzo (ine zvirevo uye data rekushanda zvakanaka/kuburitsa utsi), kana shanduro iri nyore yebasa rechikoro.
