Okokuqala, kudingeka sinciphise umkhawulo wengxoxo ukuze sigweme ukwenze kube nge-Interise. I-generator okuxoxwe ngayo lapha ibhekisela ku-generator engenasisekelo, isigaba esithathu esivumelanayo se-ac ac, lapha kuphela ngokuthi "generator".
Lolu hlobo lwe-generator luqukethe okungenani izingxenye ezintathu eziphambili, ezizoshiwo engxoxweni elandelayo:
I-Main Generator, ihlukaniswe isitayela esikhulu kanye ne-main rotor; I-rotor eyinhloko ihlinzeka ngamandla kazibuthe, futhi i-Stator eyinhloko ikhiqiza ugesi ukuhlinzeka umthwalo; I-Excenget, ihlukaniswe isitaki esijabulisayo ne-rotor; I-Exteriter Stor inikeza amandla kazibuthe, i-rotor yakha ugesi, nangemva kokulungiswa ngumdlalo ojikelezayo, inikezela amandla ku-rotor eyinhloko; I-automatic voltage Regulator (AVR) ithola ukukhishwa kwamandla akhiqizwayo we-main generator, ilawula okwamanje kwe-coil ethokozisayo ye-stator, futhi ifinyelela inhloso yokuqinisa ivola lokukhipha lesitabane esikhulu.
Incazelo ye-AVR Voltage Stingilization Work
Inhloso yokusebenza ye-AVR ukugcina amandla akhiqizayo okukhipha amandla, eyaziwa ngokuthi "iVoltage Stabilizer".
Ukusebenza kwayo ukukhulisa i-stator yamanje ye-exgiter lapho okukhishwayo kwe-generator kuphansi kunenani elisethiwe, elilingana nokwandisa i-voltage enkulu ye-rotor, ebangela ukuba kube nenani eliphambili le-rotor, Ngokuphambene nalokho, yehlisa i-exparitation yamanje futhi uvumele i-voltage yehle; Uma ukukhishwa kwe-volurtage kwe-generator kulingana nenani elisethiwe, i-AVR igcina okukhona okukhona ngaphandle kokulungiswa.
Ngaphezu kwalokho, ngokusho kobudlelwano besigaba phakathi kwamanje nogesi, imithwalo ye-AC ingahlukaniswa izigaba ezintathu:
Umthwalo wokuthula, lapho okwenziwa khona kwalesi sigaba namavolo asetshenziswa kuwo; Umthwalo ongahambi kahle, isigaba se-lags yamanje ngemuva kwamandla kagesi; Umthwalo we-capacitive, isigaba sawo samanje singaphambi kwamandla kagesi. Ukuqhathanisa izici ezintathu zomthwalo kusisiza ukuthi siqonde kangcono imithwalo ye-capacitive.
Ngemithwalo yokumelana, okukhudlwana komthwalo, kukhudlwana kwe-exparital yamanje edingekayo ku-rotor eyinhloko (ukuze aqinise amavolutela okukhishwa kwe-generator).
Engxoxweni elandelayo, sizosebenzisa i-exparitation yamanje edingekayo yemithwalo yokumelana njengesethenjwa, okusho ukuthi ukuthi kukhulu kubhekiselwa enkulu; Sikubiza ngokuthi sincane kunalokho.
Lapho umthwalo we-generator uyamangaza, i-rotor eyinhloko izodinga indawo yokuxoxa enkulu ukuze i-generator ilondoloze i-voltage ekhipha amandla.
Umthwalo we-capacitive
Lapho i-generator ihlangana nomthwalo we-capacitive, i-expacticution yamanje edingekayo yi-rotor eyinhloko incane, okusho ukuthi ukuthokozela okukhona manje kufanele kuncishiswe ukuze kuqinise i-voltator ye-generator.
Kungani lokhu kwenzeka?
Kufanele sisakhumbule ukuthi amanje emthwalweni we-capacitive angaphambi kwamandla kagesi, futhi le mvudula ehamba phambili (egeleza i-stator eyinhloko) izokhipha i-stror enkulu) izokhiqiza okwamanje ku-catoror enkulu, eyenzeke ukuthi ifakwe kahle nge-experation yamanje, ithuthukise amandla kazibuthe we-rotor eyinhloko. Ngakho-ke okwamanje okuvela kwi-exgiter kumele kwehliswe ukuze kugcinwe i-voltage esetshenzisiwe ye-generator.
Okukhulu umthwalo we-capacitive, okuncane okuphumayo kwe-exciter; Lapho umthwalo we-capacitive ukhuphuka ngezinga elithile, umphumela we-exgiter kumele ancishiswe abe ngu-zero. Ukukhishwa kwe-Excenget kungu-zero, okuwumkhawulo we-generator; Okwamanje, iVoltage ekhiqizwayo ye-generator ngeke ibe izinzile, futhi lolu hlobo lokuhlinzekwa kwamandla alufanelekile. Lo mkhawulo waziwa nangokuthi 'ngaphansi komkhawulo wokuvusa'.
I-generator ingamukela kuphela umthamo womthwalo olinganiselwe; (Vele, ku-generator ecacisiwe, kukhona nemikhawulo ngosayizi wemithwalo yokumelana noma ebabazekayo.)
Uma iphrojekthi ihlushwa imithwalo ye-capacitive, kungenzeka ukuthi ukhethe ukuyisebenzisa imithombo yamandla ye-IT nge-capacitance encane ye-Kilowatt ngayinye, noma usebenzise ama-inductivation. Ungavumeli i-generator isethwe ukuthi isebenze eduze kwendawo "ngaphansi kwe-Exciation Limit".
