Jenareta nemota zvinozivikanwa semhando mbiri dzakasiyana dzemidziyo yemakanika. Imwe ndeyekushandura imwe simba kuita simba remagetsi kuti igadzire magetsi, nepo mota ichishandura simba remagetsi kuita simba remakanika kuti rikwezve zvimwe zvinhu. Zvisinei, zviviri izvi hazvigone kuiswa uye kutsiviwa. Mamwe marudzi emajenareta nemota anogona kuchinjana mushure mekugadzirwa nekugadzirisa. Zvisinei, kana paine chikanganiso, jenareta inoshandurwawo kuita mashandiro emota, inova dziviriro yekumashure pasi pesimba rekumashure rejenareta ratinoda kutaura nezvaro nhasi.
Chii chinonzi simba rekudzosera shure?
Sezvatinoziva tese, simba rejenareta rinofanira kufamba kubva kudivi rejenareta kuenda kudivi resisitimu. Zvisinei, nekuda kwechimwe chikonzero, kana turbine ikarasikirwa nesimba remota uye switch yekubuda kwejenareta ikatadza kudonha, simba resisitimu rinochinja kubva kujenareta kuenda kusisitimu, kureva kuti, jenareta inochinja kuenda kumota iri kushanda. Panguva ino, jenareta inotora simba rinoshanda kubva kusisitimu, iro rinonzi reverse power.
Kukuvadza kwesimba rekudzosera shure
Dziviriro yemagetsi emagetsi emagetsi emagetsi emagetsi emagetsi ndeyekuti kana vharuvhu huru yemagetsi emagetsi emagetsi emagetsi yakavharwa nekuda kwechimwe chikonzero uye simba rekutanga rarasika, jenareta inoshanduka kuita mota yekufambisa turbine yemagetsi emagetsi kuti itenderere. Kutenderera nekukurumidza kwebanga remagetsi emagetsi emagetsi emagetsi emagetsi pasina turbine kunokonzera kukweshana kwemhepo, kunyanya pabanga rekupedzisira, zvinogona kukonzera kupisa zvakanyanya uye kutungamira mutsaona yekukuvara kwebanga remagetsi emagetsi emagetsi.
Saka, dziviriro yesimba rekudzokera shure idziviriro yeturbine yemhepo isina simba remhepo.
Dziviriro yejenareta yakarongwa yekudzosera simba
Kudzivirira simba remagetsi kubva pakudzokera shure kwejenareta kunonyanya kudzivirira jenareta kuti isangoerekana yagumburwa neswitch yekubuda kwejenareta pasi pemutoro wakati uye vharuvhu huru ye throttle ye turbine ye steam haina kuvharwa zvizere. Muchiitiko ichi, unit ye turbine ye steam inowanzo mhanyisa zvakanyanya uye kutomhanyisa. Kuti idzivirire mamiriro aya, kune dzimwe dziviriro dzisina kukanganisa kwe short-circuit, mushure mekunge chiratidzo che action chatumirwa, inotanga yashanda pakuvhara vharuvhu huru ye steam ye turbine ye steam. Mushure mekunge simba re * * * re generator rashanda, rinoumbwa uye vharuvhu ine chiratidzo chekuvhara vharuvhu huru ye steam, kugadzira chirongwa chekudzivirira simba re reverse mushure menguva pfupi, uye chiito chinoshanda pakumira kwakazara.
Musiyano uripo pakati pekudzivirira simba rekudzokera shure nekudzivirira simba rekudzokera shure kwechirongwa
Dziviriro yesimba rekudzokera shure ndeyekudzivirira jenareta kuti isashanduke kuita mota mushure mesimba rekudzokera shure, zvichikonzera turbine yemhepo kutenderera uye zvichikonzera kukuvara kweturbine yemhepo. Pakupedzisira, ndinotya kuti chinhu chikuru chinofambisa simba chichafambiswa nesystem kana chisina simba!
Chirongwa ichi chekudzivirira simba rekudzokera shure ndechekudzivirira kumhanya zvakanyanya kwe turbine kunokonzerwa nevharuvhu huru ye throttle isina kuvharwa zvizere mushure mekunge generator unit yangoerekana yabviswa, saka simba rekudzokera shure rinoshandiswa kudzivirira. Pakupedzisira, ndinotya kuti simba rakawandisa re prime mover richatungamira kumhanya zvakanyanya kweyuniti.
Saka, kutaura chokwadi, dziviriro yesimba rekudzokera shure rudzi rwedziviriro yejenareta, asi inonyanya kudzivirira turbine yemhepo. Dziviriro yesimba rekudzokera shure yepurogiramu haisi dziviriro, asi maitiro ekuita akagadzirirwa kuita kuti purogiramu iwire, inozivikanwawo sekuti purogiramu iwire, iyo inowanzo shandiswa kune shutdown mode.
Chinokosha ndechekuti chero bedzi simba rekudzokera shure richisvika pamutengo wakaiswa, richagumburwa. Pamusoro pekusvika pamutengo wakaiswa, simba rekudzokera shure rechirongwa rinodawo kuti vharuvhu huru ye throttle ye steam turbine ivharwe. Saka, simba rekudzokera shure rinofanira kudzivirirwa panguva yekubatanidza grid panguva yekutanga kweyuniti.
Aya ndiwo mabasa ekudzivirira jenareta kuseri uye tsananguro yesimba remagetsi rinodzoserwa kuseri. Kune jenareta yemagetsi emhepo iri kushanda negrid yakabatana, inoshanda semota inochinjana mushure mekunge vharuvhu huru yemagetsi emhepo yavharwa: inotora simba rinoshanda uye inodhonza turbine yemhepo kuti itenderere, izvo zvinogona kutumira simba remagetsi kuhurongwa. Sezvo vharuvhu huru yemagetsi emhepo yavharwa, banga remuswe weturbine yemhepo ine kukweshana nemhepo yakasara kuti igadzire kurasikirwa kwekuputika, uko kunokuvadzwa nekupisa zvakanyanya panguva yekushanda kwenguva refu. Panguva ino, dziviriro yekumashure inogona kudzivirira turbine yemhepo kubva mukukuvadzwa.
