Isifinyezo
Uhlelo lombusi luyisici esibalulekile ekukhiqizweni kwamandla kagesi ngamanzi, olunesibopho sokulawula isivinini se-turbine kanye nokukhishwa kwamandla asebenzayo ngokuphendula izinguquko zemvamisa yegridi kanye nemiyalo yokuthumela. Ukuvela kokubusa okuvela ku-mechanical-hydraulic kuya ku-microprocessor-based governors kumele igxathu eliyisisekelo lobuchwepheshe, okuthuthukisa ukunemba, ukuthembeka, kanye nokusebenza. Lesi sihloko sihlola ukwakheka, ubuchwepheshe obuyinhloko, ukusebenza, kanye nezinzuzo zokubusa kwesimanje okusekelwe ku-microprocessor (okubusa kwedijithali) ekusetshenzisweni kwamandla kagesi ngamanzi.
1. Isingeniso
Umsebenzi oyinhloko wombusi wamandla kagesi asebenzisa amanzi ukugcina ukulingana okuzinzile phakathi kwamandla kagesi aqhuba i-turbine-generator kanye namandla kagesi adingwa yigridi. Noma yikuphi ukungalingani kubangela ukuphambuka kwesivinini. Ababusi bendabuko bamandla kagesi asebenzisa ama-flyball kanye nezinhlelo ze-lever eziyinkimbinkimbi ukuze bathole futhi baphendule. Ukufika kwama-microprocessors kuguqule lezi zinhlelo zaba abalawuli bedijithali abayinkimbinkimbi, okuvumela ama-algorithms okulawula athuthukile, ukuhlanganiswa okungenamthungo nezinhlelo zokulawula izitshalo, kanye nokusebenza okunamandla okuphezulu.
2. Ukwakhiwa Kwesistimu
Uhlelo olujwayelekile lwe-governor olusekelwe ku-microprocessor luqukethe izendlalelo ezintathu eziyinhloko:
Isendlalelo Sokulawula: I-core iyisilawuli se-logic esinokwethenjelwa kakhulu (i-PLC) noma isilawuli sedijithali esizinikele. Sisebenzisa ama-algorithms okulawula, sicubungula okokufaka, futhi sibala amasignali okukhipha. Izilawuli ezingafuneki (ngokuvamile ekucushweni okulindile okushisayo) ziyindinganiso yezitshalo ezibalulekile ukuqinisekisa ukusebenza okungaphazanyiswa.
Isendlalelo Sokulinganisa Nokufaka: Lokhu kufaka phakathi izinzwa zamapharamitha ayisihluthulelo: isivinini se-turbine (esilinganiswa ngama-probe amagnetic noma ama-frequency), i-guide vane noma indawo yenaliti (ngama-transducers esikhundla), ukuphuma kwamandla, kanye nemvamisa yegridi. Iphinde ithole ama-setpoints avela ekulawulweni kwesitshalo noma kumqhubi wegridi.
Isendlalelo Sokusebenza Kwe-Electro-Hydraulic: Isignali yokulawula yedijithali ebaliwe iguqulwa ibe yisignali ye-analog futhi ikhuliswe yi-converter ye-electro-hydraulic (ngokuvamile i-servo noma i-valve elinganayo). Le valve ilawula ngokunembile ukugeleza kukawoyela we-hydraulic kuya ku-actuator eyodwa noma ngaphezulu (ama-cylinder e-servo) ahambisa ngokomzimba ama-vane okuqondisa e-turbine, ama-runner blades (kuma-turbine e-Kaplan), noma inaliti (kuma-turbine e-Pelton).
3. Ubuchwepheshe Bokulawula Okuyinhloko
Ubuhlakani bombusi wedijithali busezindleleni zakhe zokulawula ezisetshenziswa yisoftware.
Ukulawulwa kwe-PID: I-algorithm ye-Proportional-Integral-Derivative isalokhu iyitshe lesisekelo. I-microprocessor ivumela ukulungiswa okuzimele, okunembile, kanye nokuguquguquka kwamapharamitha e-P, I, kanye ne-D ezindleleni zokusebenza ezahlukene (isb., ukuqalisa, igridi ehlukanisiwe, uxhumano olukhulu lwegridi).
Amasu Okulawula Okuthuthukisiwe: Ababusi banamuhla bavame ukufaka amasu ayinkimbinkimbi kakhulu:
Ukulawula Okuguquguqukayo/Okungaguquki: Kulungisa amapharamitha ngokuzenzakalelayo ezicini ze-turbine ezingezona eziqondile ngaphansi kwezimo zekhanda nokugeleza ezishintshashintshayo.
Ukulawulwa Kwempendulo Yesifundazwe: Kuthuthukisa ukuzinza kanye nokusabela kwezinhlelo ze-hydraulic eziyinkimbinkimbi ezinezitokisi ezinde.
Impendulo Evela Kabili kanye Neyamandla: Isetshenziselwa ukuthuthukisa ukudambisa ngesikhathi sokwenqatshwa komthwalo kanye nemicimbi yesikhashana.
4. Imisebenzi Eyinhloko
Ngale komthethonqubo wejubane oyisisekelo, abaphathi bedijithali banikeza imisebenzi ephelele:
Ukuphathwa Kwemodi Yokusebenza: Ukushintshana okungenamthungo phakathi koLawulo Lwesivinini (kumagridi ahlukanisiwe noma ukuqalisa), Ukulawulwa Kwamandla (kokuthunyelwa okuxhunywe kugridi), kanye nokulawulwa kwezinga lamanzi/ukugeleza (kokunisela noma izinhlelo zokusebenzisa umfula).
Uchungechunge Lokuqalisa Nokuvala: Uchungechunge oluzenzakalelayo oluphelele, oluhlelekayo lokusheshisa, ukuvumelanisa, kanye nokuma kwe-turbine okubushelelezi nokuphephile.
Ukuvikelwa Nokuxilonga: Ukuzihlola okuqhubekayo, ukubhala amaphutha, kanye nezimpendulo zokuvikela (isb., ukuvalwa kwesango okusheshayo lapho kutholakala isivinini esikhulu, ukubuyela emuva eziteshini zokusekelayo).
Ukuxhumana Nokuhlanganiswa: Ukusekelwa kwezinqubo ezijwayelekile zezimboni (IEC 61850, Modbus, PROFIBUS) kwenza kube lula ukuhlanganiswa ohlelweni lwe-SCADA (Supervisory Control and Data Acquisition) lwesitshalo kanye nenethiwekhi yokulawula igridi ebanzi.
Ukuthuthukiswa Kokusebenza: Izici ezifana ne-Dead Zone Compensation yokungqubuzana komshini kanye nokulungiswa kwe-Nonlinear Gain kuthuthukisa ikhwalithi yokulawula kulo lonke uhla lokusebenza.
5. Izinzuzo ngaphezu kwezinhlelo zendabuko
Izinzuzo zababusi abasekelwe kuma-microprocessor zikhulu kakhulu:
Ukunemba Okuphezulu Nokuzinza: Ukucubungula kwedijithali kususa ukukhukhuleka kanye nebhendi efile ehlotshaniswa nokuxhumana kwemishini, okuvumela ukulawulwa kwemvamisa okunembe kakhulu (± 0.1% noma ngaphezulu).
Ukuzivumelanisa nezimo Nokuzivumelanisa Nezimo: Amasu okulawula kanye namapharamitha aguqulwa kalula ngesofthiwe ngaphandle kwezinguquko zehadiwe, okuvumela ukwenziwa ngcono kwezimo ezithile zesayithi.
Ukwethenjelwa Okuthuthukisiwe: Ukuncipha kokuguguleka kwemishini, ukuxilongwa okuphelele, kanye nokwakheka okungafuneki kwandisa kakhulu isikhathi esimaphakathi phakathi kokwehluleka (i-MTBF).
Ukusebenza Okuthuthukisiwe: Ivumela ukulandelana kokulawula okuyinkimbinkimbi, izinsizakalo zegridi ezihambisanayo (njengokuphendula okusheshayo kwemvamisa), kanye nokufakwa kwedatha kokuhlaziywa kokusebenza.
Ubulula Bokulungisa Nokuhlola: Ukuxilongwa kwephutha kwenziwa lula, futhi izindlela zokulingisa zivumela ukuhlolwa okuphelele ngaphandle kokusebenzisa i-turbine yangempela.
6. Isiphetho
I-governor esekelwe kuma-microprocessor iyisisombululo esiqondile sokulawulwa kwamandla kagesi anamuhla. Ishintshe kusukela ekubeni yi-regulator elula yaba yi-node yokulawula ehlakaniphile, enethiwekhi ebalulekile ekusebenzeni kahle kwezitshalo, ukuzinza kwegridi, kanye nokuhlinzekwa kwezinsizakalo ezibalulekile zegridi. Njengoba ukungena kwamandla avuselelekayo kukhula, impendulo esheshayo, enembile, neguquguqukayo yababusi bedijithali izoba yinto ebaluleke kakhulu ekugcineni ukungabi namandla kwesistimu yamandla kanye nokuzinza kwemvamisa. Intuthuko yesikhathi esizayo cishe izogxila ekuvikelekeni kwe-cyber okuthuthukisiwe, ukuhlanganiswa okujulile namawele edijithali esitshalo sonke, kanye nama-algorithms okulawula okubikezela athuthukisiwe aqhutshwa yi-AI.
