Kokubili amandla kagesi kanye namandla ashisayo kumele abe ne-exciter. I-exciter ngokuvamile ixhunywe ku-shaft enkulu efanayo nejeneretha. Lapho i-shaft enkulu izungeza ngaphansi kwe-drive ye-prime mover, ngesikhathi esifanayo ishayela i-generator kanye ne-exciter ukuze ijikeleze. I-exciter iyijeneretha ye-DC ekhipha amandla e-DC, athunyelwa kukhoyili ye-rotor ngendandatho eshelelayo ye-rotor ye-generator ukuze ikhiqize insimu kazibuthe ku-rotor, ngaleyo ndlela ikhiqize amandla akhangwe ku-stator ye-generator. I-exciter yesethi enkulu yejeneretha ithathelwa indawo yi-self-shunt AC excitation system, iningi lazo elisebenzisa i-voltage ye-generator outlet ukuze idlulise uguquko oluvusa amadlingozi, idlule emshinini wokulungisa ibe wamanje oqondile, bese ithumela owamanje ngendandatho yesiliphu ye-generator rotor. ku-rotor ye-generator. Uma lolu hlobo lwesistimu lusetshenziswa, ukuvuswa kokuqala kwejeneretha kufanele kwenziwe isikhathi ngasinye lapho ivuliwe, okuwukwengeza isasasa lokuqala kujeneretha ukuze kusungulwe i-voltage yokuqala ye-generator.
Injabulo ye-exciter yakudala incike ekuzinzeni kwayo, okungenza i-exciter ikhiqize ugesi, kodwa amandla mancane kakhulu futhi i-voltage ibuthakathaka kakhulu, kodwa lokhu okwamanje okubuthakathaka kudlula ikhoyili ye-exciter ye-exciter ukuqinisa ukuqina. umphumela. Le nsimu kazibuthe eqinisiwe iyaqhubeka nokwenza i-exciter ikhiqize ugesi, okungamandla angaphezu kwamandla kazibuthe asele, bese iphinda lokhu ngokuphindaphindiwe, i-voltage ekhishwa yi-exciter ingaba phezulu nangaphezulu, okusho ukuthi, ugesi okhishwa yi-exciter ungowokuqala ngokwawo. Isetshenziselwa ukusungula ikhono layo, futhi inikeze kuphela ukuvuswa kwejeneretha lapho i-voltage ethile ephezulu ifinyelelwa. Isistimu ye-excitation yamasethi amakhulu ejeneretha yesimanje isebenzisa isistimu yokuvusa i-microcomputer, futhi ukuvuswa kwayo kwasekuqaleni kunikezwa ukunikezwa kwamandla okuqala okuvusa amandla, okuhlinzekwa yigridi yamandla noma ukunikezwa kwamandla kwe-DC kwesikhungo sikagesi.
