Seti yejenareta kazhinji ine injini, jenareta, yakazara kudzora sisitimu, oiri redunhu system, uye simba rekugovera sisitimu.Chikamu chesimba chejenareta chakaiswa muhutano hwekukurukurirana - injini ye dizeli kana gasi turbine injini - inonyanya kufanana nepamusoro-kudzvinyirira uye kuderera-kuderedza zvikamu;Kugadziriswa uye huwandu hwemafuta eiyo oiri system inonyanya kuenderana nesimba, saka hapana mutsauko wakakosha pakati peakakwira uye yakaderera kudzvanywa mayuniti, saka hapana mutsauko mune zvinodiwa zvekupinda kwemhepo uye exhaust masisitimu emayuniti anopa kutonhora.Misiyano yeparameter uye kuita pakati pe-high-voltage generator seti uye yakaderera-voltage generator seti inonyanya kuratidzwa muchikamu chejenareta uye chikamu chekugovera system.
1. Kusiyana kwehuwandu uye uremu
Maseti emagetsi ejenareta anoshandisa majenareta akakwira-voltage, uye kuwedzera kwevoltage level kunoita kuti zvavanoda zvekudzivirira zvikwire.Saizvozvo, vhoriyamu uye uremu hwechikamu chejenareta zvakakura pane izvo zvepasi-voltage units.Naizvozvo, huremu hwemuviri wese uye huremu hwe10kV generator set yakakura zvishoma pane iyo yepasi-voltage unit.Hapana mutsauko wakakosha pakuonekwa kunze kwechikamu chejenareta.
2. Kusiyana kwemaitiro ekugadzirisa pasi
Nzira dzisina kwazvakarerekera dzemajenareta seti dzakasiyana.Iyo 380V unit winding ine nyeredzi yakabatana.Kazhinji, iyo yakaderera-voltage system inzvimbo isina kwayakarerekera yakananga pasi system, saka nyeredzi yakabatana isina kwayakarerekera poindi yejenareta inoiswa kuti ibviswe uye inogona kudzika yakananga painodiwa.10kV sisitimu idiki yazvino yepasi system, uye iyo isina kwayakarerekera poindi kazhinji haina kudzika kana kudzika pasi kuburikidza nepasi kuramba.Naizvozvo, zvichienzaniswa neakadzika-voltage mayuniti, 10kV mayunitsi anoda kuwedzerwa kweasina kwaakarerekera point yekugovera michina yakadai seyekudzivirira makabati uye contactor makabati.
3. Kusiyana kwekudzivirira nzira
High voltage jenareta seti kazhinji inoda kuisirwa ikozvino kukurumidza kuzorora kudzivirira, kuchengetedzwa kwekuremerwa, kuchengetedzwa kwepasi, etc. Kana kunzwisiswa kwezvino kukurumidza kuvharwa kwekudzivirira kusingaite zvinodiwa, longitudinal differential protection inogona kuiswa.
Kana kukanganisa kwepasi kuchiitika mukushanda kwe-high-voltage generator set, inokonzera njodzi huru yekuchengetedza kuvashandi nemidziyo, saka zvakakosha kuisa kuchengetedzwa kwekukanganisa kwepasi.
Iyo isina kwayakarerekera poindi yejenereta yakavakirwa kuburikidza neanopikisa.Kana imwe-chikamu chepasi chikanganiso chikaitika, chikanganiso chirikuyerera nepanzvimbo isina kwayakarerekera chinogona kuwonekwa, uye kudonha kana kuvharika kudzivirira kunogona kuwanikwa kuburikidza nerelay kuchengetedza.Iyo isina kwayakarerekera poindi yejenereta yakadzikwa kuburikidza neanopikisa, iyo inogona kudzikamisa kukanganisa ikozvino mukati meiyo inobvumirwa kukuvadza curve yejenareta, uye jenareta inogona kushanda nekukanganisa.Kuburikidza nekuramba kwepasi, kukanganisa kwepasi kunogona kunyatsowonekwa uye zviito zvekudzivirira relay zvinogona kufambiswa.Zvichienzaniswa ne-low-voltage units, high-voltage generator seti inoda kuwedzerwa kwezvakarerekera pfungwa yekuparadzira michina yakadai semakabati ekupikisa uye contactor makabati.
Kana zvichidikanwa, kudzivirira kwakasiyana kunofanirwa kuiswa kune yakakwira-voltage generator seti.
Ipa matatu-chikamu ikozvino mutsauko kudzivirirwa pane stator mhepo yejenareta.Nekuisa matransformer azvino pamaterminal maviri anobuda ega yega coil mujenareta, mutsauko uripo pakati peinouya neinobuda materminals ekoiri inoyerwa kuti uone mamiriro ekudzivirira kwecoil.Kana kupfupika kwedunhu kana kudzika kunoitika mune chero maviri kana matatu nhanho, kukanganisa ikozvino kunogona kuonekwa mune ese matransformer, nekudaro kutyaira kudzivirira.
4. Kusiyana kwetambo dzekubuda
Pasi peyero imwechete yesimba, iyo yekubuda tambo dhayamita yeakakwira-voltage mayuniti idiki zvakanyanya pane iyo yakaderera-voltage mauniti, saka iyo nzvimbo yekugara inodiwa kune yekubuda nzira yakadzikira.
5. Kusiyana muUnit Control Systems
Iyo unit control system ye low-voltage units inogona kazhinji kubatanidzwa kune rimwe divi rejenareta chikamu pamushini wechina, nepo ma-high-voltage mauniti kazhinji anoda yakazvimirira unit control bhokisi kuti arongwe zvakaparadzana neyuniti nekuda kwekukanganisa kwezviratidzo.
6. Kusiyana kwezvinodiwa zvekuchengetedza
Zvinodiwa zvekuchengetedza kweakakwira-voltage jenareta mayunitsi muzvikamu zvakasiyana senge oiri yedunhu system uye mhepo yekupinda uye exhaust system yakaenzana neiyo yakaderera-voltage mayunitsi, asi kugovera kwesimba kwemayuniti ndeye yakakwira-voltage system, uye vashandi vekuchengetedza. inoda kuve yakashongedzerwa ne high-voltage work permits.
