I-Microprocessor Based Excitation System
Uhlelo lwe-excitation luhlinzeka ngokuyinhloko kuma-rotor windings we-hydro-generator ukuze kusungulwe insimu kazibuthe. Umsinga oqondile uvame ukusetshenziselwa ukwakha insimu kazibuthe.
Imisebenzi esemqoka yesistimu ye-excitation inamaphuzu angu-5:
1. Nikeza amandla e-excitation ye-synchronous generator futhi ulungise i-excitation current;
2. Ukuhlinzeka ngesasasa eliphoqelelwe ukuze kuthuthukiswe ukuzinza kwesistimu yamandla;
3. Ijeneretha iphoqeleka ukuthi ikhiphe uzibuthe ukuze ibeke umkhawulo ku-voltage ngaphezulu;
4. Isesimweni sokuncisha injabulo lapho kwenzeka isifunda esifushane;
5. Amandla asebenzayo ejeneretha anikezwa ngenkathi amayunithi amaningi esebenza.
Umkhiqizo Isingeniso
Izici eziyinhloko zesistimu ye-excitation
1. Isakhiwo esishumekiwe esijwayelekile;
2. Izigaba ezi-3 zebhuloho elilawulwa ngokugcwele;
3. Indlela yokulawula yokuzivumelanisa nezimo;
4. Ngamandla amakhulu, ingaklanywa ngamabhuloho amabili noma amabhuloho amaningi;
5. I-coefficient yokulinganisa yamanje yamabhuloho amaningi > 0.95;
6. Ukuboniswa okuqondile (isikrini sokuthinta singokuzithandela);
7. Ikhono elikhulu lokushayela umfutho;
8. Qedela umsebenzi wokuzihlola;
9. Qedela umsebenzi wokuvikela umkhawulo;
10. Ukunikezwa kwamandla okubili okuthembekile.
