Umenzi weJenereyitha uxelela ngengozi yeSigaba sokuSebenza

Iseti yejenereyitha ye-Diesel: nge-injini, i-generator kunye nokwakheka kwenkqubo yokulawula, ebizwa ngokuba yisethi ye-generator. Iseti yejenereyitha yedizili luhlobo lwezixhobo zamandla ezithatha i-injini ye-diesel njenge-prime mover kunye ne-synchronous generator ukuvelisa umbane.Sisixhobo sokuvelisa amandla esinesiqalo esikhawulezayo, ukusebenza ngokufanelekileyo kunye nokugcinwa, utyalo-mali oluncinci kunye nokuguquguquka okunamandla kokusingqongileyo.

Xa i-generator iqhuba ngokuqhelekileyo, inika amandla asebenzayo kunye ne-reactive kwi-system, kwaye i-stator yangoku ibeka emva kwe-terminal voltage nge-Angle.Lo mbuso ubizwa ngokuba yi-post-operation.Xa i-excitation yangoku iyancipha ngokuthe ngcembe, i-generator iyatshintsha ukusuka ekunikezeni amandla asebenzayo ukufunxa amandla asebenzayo avela kwisistim, kunye ne-stator yangoku itshintsha ukusuka kwi-lagging ukuya kwi-voltage ye-terminal ye-generator nge-Angle.Lo mbuso ubizwa ngokuba yinkqubo yesigaba esikhokelayo.Xa ijeneretha ye-synchronous isebenza kwangaphambili, i-excitation current iyancipha kakhulu, kwaye i-Eq enokubakho ye-generator iyancipha ngokufanelekileyo.Ukusuka kwi-P-power Angle relation, xa amandla asebenzayo ehlala, i-Angle yamandla iya kunyuka ngokuhambelanayo, umlinganiselo wamandla onke wesinyathelo uya kuncipha ngokuhambelanayo, kwaye ukuzinza kwe-static ye-generator kuya kuncipha.Umda wayo wokuzinza uhambelana nomlinganiselo wesiphaluka omfutshane we-generator, ukusabela kwangaphandle, ukusebenza kwe-automatic excitation regulator kunye nokuba ifakwe ekusebenzeni.

Xa kuthelekiswa nokusebenza kamva, ukuvuza kwe-flux ekupheleni kwe-stator ijenereyitha ukwanda komsebenzi ophezulu.Ingakumbi umthwalo womgca wejenereyitha omkhulu uphezulu, isiphelo sokuvuza kwemagnethi kukhulu ekusebenzeni okuqhelekileyo, isiphelo soxinzelelo olungundoqo lubhekiselele kubushushu bokwanda kwesihlanganisi, kwangethuba umsebenzi wesigaba sokuvuza kwemagnethi ukonyuka, ukunyuka kwamaqondo obushushu kuyenziwa ngamandla.Ngethuba lokusebenza kwesigaba esikhokelayo, i-voltage terminal ye-generator iyancipha, kwaye i-voltage encedisayo iyancipha ngokufanelekileyo.Ukuba idlula i-10%, iya kuchaphazela ukusebenza kwamandla ancedisayo.

Ke ngoko, ubunzulu bokusebenza bejeneretha ehambelanayo kufuneka bugqitywe ngovavanyo.Oko kukuthi, mangakanani amandla asebenzayo anokuthi afunwe ukugcina uzinzo lwe-static kunye nolwexeshana lwenkqubo, kwaye ukunyuka kwamaqondo okushisa kwecandelo ngalinye akudluli umda wokuhlangabezana neemfuno zombane.

Iingozi ezibangelwa kukusebenza kwesigaba ngumenzi wejenereyitha:

1. Ukwandisa umthwalo osebenzayo wejeneretha kuya kwenza i-generator ingazinzi, eya kubangela lula ukusebenza okungazinzanga kwejeneretha kunye nokubakho kweengozi ze-oscillation system.

2. Qhubeka nokunciphisa i-excitation current ye-generator kunye nokwandisa ubunzulu besigaba esiphezulu se-generator, esinokukhokelela ekulahlekelweni kwesenzo sokukhusela i-excitation ye-generator okanye ukusebenza okungazinzanga kwejeneretha.

3. Xa i-generator isebenza kwangaphambili, i-stator yangoku iyanda kwaye ukushisa kwe-stator kwanda;Xa i-generator isebenza kwisigaba sangaphambili, izinga lokuvuza kwe-flux ye-stator end yanda, okwenza ubushushu bokugqibela bube bunzulu kakhulu, kwaye ubushushu be-coil ye-stator ye-generator iya kuqhubeka nokunyuka.

4. Xa i-generator isebenza phambi kwesigaba, i-voltage ye-generator outlet iyancitshiswa, ukwenzela ukuba i-voltage yebhasi ye-6KV iyancipha.Amandla ombane aphezulu anokhuseleko lwangaphantsi kwamandla ombane aya kuhamba;Kuzo zonke izixhobo zombane ezisebenzayo, i-voltage yebhasi iyancipha kwaye ukunyuka kwangoku, kubangela ukuba izixhobo zifudumale.Ukusebenza kwexesha elide kunokonakalisa ukugquma kwesixhobo.
