Ubuchwepheshe Bamuva Ezinhlelweni Zokulawula Ukushisa Komhlaba
Amandla e-geothermal abonakala kakhulu njengensika yokuguquka kwamandla ngenxa yekhono lawo lokuhlinzeka ngogesi ozinzile nokushisa (umthwalo wesisekelo), ukukhishwa okuphansi kakhulu, kanye nokuphepha okuphezulu kokunikezwa. Kodwa-ke, leli khono alinakwandiswa ngaphandle kohlelo lokulawula oluthembekile. Ngokungafani nezitshalo zamandla ezivamile, izinhlelo ze-geothermal zibhekene nezinselele ezihlukile: uketshezi lokukhiqiza oluqothulayo, izinga lokushisa elibi kakhulu kanye nezimo zokucindezela, ingozi yokukhula (imvula yamaminerali), kanye nokuguquguquka okuyinkimbinkimbi kwedamu. Ngakho-ke, eminyakeni yamuva nje, ukusungula izinto ezintsha kubuchwepheshe bokulawula i-geothermal kuthuthuke ngokushesha—kusukela ezinzwaneni ezihlakaniphile kanye nama-algorithms okwenza ngcono kuya ekuhlanganisweni kwedijithali okusekelwe kubuhlakani bokwenziwa.
1. Ukwenziwa kwedijithali kanye nokwakhiwa kokulawula kwesimanje: kusukela ku-SCADA kuya ku-"smart geothermal"
Ngokomlando, izikhungo eziningi ze-geothermal ziye zathembela ku-SCADA (Ukulawula Ukuphatha Nokuthola Idatha) kanye ne-PLC/DCS (Uhlelo Lokulawula Oluhlelekile/Uhlelo Lokulawula Olusatshalaliswayo) ukuze kuqashwe futhi kulawulwe inqubo. Ubuchwepheshe obusha abuthathi indawo yalesi sisekelo, kodwa kunalokho bandisa amakhono aso ngokusebenzisa izakhiwo ezivulekile, ezihlanganisiwe, nezicebile ngedatha.
Umkhuba osanda kuvela "i-smart geothermal," uhlelo lokulawula olungagcini nje ngokuqapha izinguquko zenqubo (ingcindezi, izinga lokushisa, izinga lokugeleza) kodwa futhi luhlanganisa idatha yokugcina, i-chemistry yoketshezi, ukusebenza kwe-turbine, ngisho nokubikezela ukuphazamiseka. Umphumela uba ukwenza izinqumo okusheshayo nokuqhutshwa ukuhlaziya. Ngaphezu kwalokho, opharetha abaningi bahambisa i-analytical computing baye kuma-edge computing—amadivayisi ekhompyutha endawo ensimini—ukuze basheshise izimpendulo zokulawula futhi banciphise ukuthembela ekuxhumaneni kwenethiwekhi okungazinzile.
2. Inzwa yesizukulwane esisha: ukuqina okukhulu, ukuqina futhi kuhlakaniphe kakhulu
Izinhlelo zokulawula ezithuthukisiwe zincike kwikhwalithi yedatha. Ezindaweni ezishisayo, izinzwa zibhekana namazinga okushisa aphezulu, ukucindezela okuphezulu, ukudlidliza, kanye nokuchayeka ku-H₂S nezinye izinto ezibolayo. Ubuchwepheshe bamuva buhlinzeka ngezinzwa ezikwazi ukumelana nezimo ezimbi kakhulu futhi ezinembe kakhudlwana.
Ezinye izinto ezintsha eziphawulekayo zifaka phakathi izinzwa zomgodi ongaphansi (ngaphakathi komthombo) ezinezinto eziqinile kanye nokuvala, kanye nokuzwa kwe-fiber optic ukuqapha amazinga okushisa njalo emthonjeni (ukuzwa kokushisa okusabalalisiwe/i-DTS). Kukhona futhi nokuzwa kwe-acoustic okusabalalisiwe (i-DAS), okusebenzisa i-fiber optics ukufunda ukudlidliza noma izimpawu ze-acoustic, okuvumela opharetha ukuthi babone izinguquko zokugeleza, ukuvuza, noma umsebenzi we-micro-seismic kusenesikhathi. Ngale datha enesinqumo esiphezulu, amasu okulawula angenziwa aqonde kakhulu futhi aphendule.
3. Ukulawula ukubikezela okusekelwe kumodeli (i-MPC) kokwenza ngcono umkhiqizo kanye nokuzinza
Enye yezindlela ezibalulekile zokulawula inqubo yesimanje yi-Model Predictive Control (MPC). Ngokungafani nokulawula kwe-PID okuvamile, okusabela emaphutheni amanje, i-MPC ibikezela ukuziphatha kwesistimu yesikhathi esizayo ngokusebenzisa amamodeli enqubo. Ezimweni ze-geothermal, i-MPC ingasetshenziswa uku:
- Kuqinisa ingcindezi yekhanda lomusi lapho ukukhiqizwa komthombo kushintshashintsha
– Lungiselela ukwabelana ngomthwalo phakathi kwemithombo yokukhiqiza ukuze kulondolozwe ukusebenza kwe-turbine futhi kuvinjelwe ukuwohloka kwedamu.
– Ukulawula ukujova ukuze kungabangela ukushesha okukhulu kokushisa (ukwehla kwezinga lokushisa ngenxa yamanzi okujova abuyela ngokushesha kakhulu endaweni yokukhiqiza)
Nge-MPC, opharetha bangagwema imisebenzi "yokulungisa ngokweqile" evame ukubangela ukunyakaza, ngenkathi bekhulisa amandla ngaphandle kokubeka engcupheni impilo yesikhathi eside yedamu.
4. Ubuhlakani bokwenziwa kanye nokufunda komshini: kusukela ekutholakaleni kwe-anomaly kuya ekwenzeni ngcono izinhloso eziningi
I-AI kanye nokufunda komshini (i-ML) kuya ngokuya kusetshenziswa njengezendlalelo zokuhlaziya phezu kwezinhlelo zokulawula. Izinhlelo zokusebenza zifaka:
1. Ukutholwa kwe-anomaly yesikhathi sangempela: I-ML ifunda amaphethini okusebenza ajwayelekile futhi inikeza ama-alamu uma kukhona ukuphambuka okuncane okungaba yizinkinga ezinkulu, isibonelo izinkomba zokukala, ukwehla kokusebenza kahle kokuhlukanisa, noma ukuwohloka kwephampu.
2. Ukubikezela ukwehluleka (ukulungiswa kokubikezela): Ngedatha yokudlidliza, izinga lokushisa lamabhere, ugesi wemoto, kanye nomlando wokusebenza, amamodeli e-ML angabikezela ukuthi izingxenye ezibalulekile zidinga ukuhlolwa noma ukushintshwa nini.
3. Ukuthuthukisa ukusebenza: Ama-algorithms okuthuthukisa asekelwe ku-AI angalinganisa imigomo eminingi ngasikhathi sinye—isibonelo, ukukhishwa kwamandla okuphezulu, ukusetshenziswa okuncane kwezinambuzane, imikhawulo yokukhishwa kwe-H₂S, kanye nesikhathi sokuphila kwemishini.
Imiphumela engokoqobo ukunciphisa isikhathi sokungasebenzi, ukonga izindleko zokulungisa, kanye nokwanda kwezici zamandla ezitshalo.
5. I-Digital twin: ikhophi ebonakalayo yokulingisa okuphephile, ukuqeqeshwa, kanye nezinqumo.
I-digital twin iyikhophi yedijithali yempahla ebonakalayo (kahle, ipayipi, isihlukanisi, i-turbine, uhlelo lokupholisa) oluvuselelwa njalo ngedatha yokusebenza. Ku-geothermal, ama-digital twin asetshenziselwa ukulingisa izimo ezingaphephile noma ezibizayo ukuzihlola ngqo, njengokushintsha kwesu lokujova, ukwengezwa kwemithombo emisha, noma impendulo yesistimu ekuphazamisekeni kwenethiwekhi.
Ngaphezu kokwenza ngcono, amawele edijithali nawo ayasiza ekuqeqeshweni kwabaqhubi: angafunda ukuphatha izimo ezingavamile ngaphandle kokufaka imishini engozini. Njengoba izikhungo ze-geothermal ziya ngokuya ziba nzima, amawele edijithali asiza ukuhlanganisa amaqembu okusebenza kwezindawo zokugcina amanzi, ukukhiqiza, kanye nezitshalo "ngolimi" olulodwa, oluqhutshwa yimodeli kanye nedatha.
6. Ukulawulwa kwamakhemikhali okuzenzakalelayo kanye nokunciphisa ukukala/ukugqwala
Izinkinga zokukhula (i-silica, i-calcite, noma amanye amaminerali) kanye nokugqwala kuyizimbangela zokwehla okukhulu kokusebenza. Ubuchwepheshe bamuva buthuthukisa izinhlelo zokulawula amakhemikhali ngokuthi:
– Ukuqapha amakhemikhali ku-inthanethi (i-pH, ukuhanjiswa kwamandla, i-ORP, okuqukethwe kwe-ion ethile)
- Ukulinganisa ngokuzenzakalelayo kwamakhemikhali okuvimbela ukukala, ukuvimbela ukugqwala, noma ukulungiswa kwe-pH
- Ukulinganisa ubungozi obuhlanganisa izinga lokushisa, ingcindezi, kanye nokwakheka koketshezi ukuze kubikezelwe izindawo zokubeka
Ngokulawulwa kwamakhemikhali okuhlakaniphile, abaqhubi banganciphisa imvamisa yokuhlanza, bandise impilo yamapayipi kanye ne-heat exchanger, futhi balondoloze ukudluliselwa kokushisa okuhle kakhulu.
7. Ukuhlanganiswa nezinhlelo zikagesi kanye nokuguquguquka kokusebenza
Nakuba amandla okushisa komhlaba aziwa ngokuzinza kwawo, igridi yesimanje idinga ukuguquguquka okukhulu. Ubuchwepheshe bamuva bokulawula buvumela izitshalo ezishisayo ukuba ziphendule ezinguqukweni zomthwalo, ukuhlanganiswa kweminye imithombo yamandla avuselelekayo (ilanga/umoya), kanye nesidingo sezinsizakalo ezihambisanayo (isb., ukulawulwa kwemvamisa).
Izilawuli ze-turbine, i-steam valve, kanye nesistimu ye-condenser manje sezihlanganiswa kakhulu nezimpawu ezivela kugridi. Ngamasu okulawula afanele, izitshalo zamandla zingagcina ukusebenza kahle ngenkathi zinciphisa ingozi yokucindezeleka kokushisa emishinini okubangelwa ukushintsha komthwalo okusheshayo.
8. Ukuphepha kwe-inthanethi (ukuphepha kwe-OT) njengengxenye yokuklama kokulawula
Njengoba ukuxhumana kanye nokusetshenziswa kwamafu/onqenqemeni kukhuphuka, izingozi zokuphepha kwe-inthanethi ezinhlelweni zobuchwepheshe bokusebenza (i-OT) nazo ziyanda. Ngakho-ke, ubuchwepheshe bamuva ekulawulweni kwe-geothermal abugxili nje ekusebenzeni kahle kodwa futhi bucabangela:
- Ukuhlukaniswa kwenethiwekhi phakathi kwe-IT ne-OT
– Ukuqapha ukungalingani kwethrafikhi yenethiwekhi yezimboni
- Ukuphathwa kwe-patch kanye nokufinyelela okusekelwe ezindimeni
- Ukuhlola umkhondo wezinguquko kumapharamitha okulawula abalulekile
Ukuphepha kwe-inthanethi okuqinile kubalulekile ukuvimbela ukuzenzekela kanye nokusetshenziswa kwedijithali ekuvuleni izikhala ezingathinta ukuphepha kanye nokuqhubeka kokusebenza.
Isiphetho
Ubuchwepheshe bamuva ezinhlelweni zokulawula ukushisa komhlaba buqhubekela phambili ekusetshenzisweni kwedijithali okukhulu, ukubikezela, kanye nokuhlanganiswa. Izinzwa zesizukulwane esilandelayo, i-MPC, i-AI/ML, amawele edijithali, kanye nokulawula kwamakhemikhali okuzenzakalelayo kuvumela abaqhubi ukwandisa ukukhiqizwa kwamandla ngenkathi begcina impilo yesitoreji kanye nokuphila kwesikhathi sempahla. Kuhlanganiswe nokuhlanganiswa ezidingweni zegridi kanye nokuphepha kwe-cyber okuthuthukisiwe, izinhlelo zokulawula ukushisa komhlaba zanamuhla azisezona nje "zokuphatha ama-valve namaphampu," kodwa kunalokho ziyizikhungo zobuhlakani ezisebenzayo ezixhumanisa idatha, amamodeli, kanye nezinqumo. Kusukela phambili, izitshalo ze-geothermal ezincintisana kakhulu kuzoba yilezo ezihlanganisa lezi zindlela zokulawula nemisebenzi yasensimini ehlelekile - zifinyelela ukusebenza kahle okuphezulu, isikhathi esincane sokungasebenzi, kanye nokusimama kwesikhathi eside.
