Yiziphi izindlela zokulungisa zesilawuli sokuvusa amajeneretha?

Imingcele yejeneretha ihlanganisa indlela yokuvusa. Ngakho-ke, enqubweni yokusetshenziswa kwangempela, yiziphi izindlela zokulungisa isilawuli sokuvusa i-generator?

〖1〗Imodi yokusebenza ye-terminal voltage (okuzenzakalelayo) njalo

Lena imodi yokulungiswa okuzenzakalelayo kwe-loop yesistimu ye-generator excitation. Kule modi yokusebenza, umsebenzi oyinhloko wesilawuli se-digital excitation ukugcina i-terminal ye-generator voltage ingashintshi. Ngokuvamile, i-terminal voltage isetshenziswa njengokuguquguquka kwempendulo ukuthola ukulungiswa kwe-PID. Phakathi naleso sikhathi, ukuze kuthuthukiswe izimo zokuzinza kokusebenza kwesistimu yamandla, isilawuli se-digital excitation singasebenzisa futhi imithetho yokulawula eyinkimbinkimbi, njenge-power system stabilizer (PSS) - yini okufanele uyazi mayelana ne-PSS yesistimu yokuvusa? Ukulawula okwengeziwe, isilawuli se-linear optimal excitation (LOEC), isilawuli se-non-linear excitation (NEC), njll.

〖2〗 Imodi yokusebenza ye-excitation yamanje (ngemanuwali).

Ngokuvamile, isilawuli esivusa amadlingozi sinezinhlobo ezimbili zokusebenza: "okuzenzakalelayo" kanye "nemanuwali", futhi isilawuli sokuvusa amadlingozi siyafana. Kumodi yokusebenza yamanje (yemanuwali), isilawuli se-digital excitation isampula yesiginali yokufaka, siyiqhathanise nevelu enikeziwe, bese sithumela isiginali yokulawula esigabeni - iyunithi ye-trigger eshintshashintshayo ngemuva kokusebenza komthetho wokulawula olinganiselwe (ohlangene). Njengoba uhla lokusetha i-voltage yemodi yokusebenza okuzenzakalelayo lunqunyelwe, ngesikhathi sokuhlolwa kwe-generator voltage - boosting ngemva kokufaka iyunithi, ukulungiswa noma ukukhubeka kweyunithi, imodi yezandla ngokuvamile isetshenziselwa ukulungisa ukuvuswa kwejeneretha ukuze kulawulwe i-terminal voltage noma amandla asebenzayo we-generator. Ngale ndlela, ukulungiswa kuzinzile futhi ububanzi bokulungisa bungaba banzi kakhulu.

I-1） Imodi yokusebenza yesistimu enamayunithi amathathu

Uma kuqhathaniswa nemodi yokusebenza lapho kusetshenziswa izilawuli ezimbili njengezipele komunye nomunye, inhloso enkulu yokwamukela isistimu yamayunithi amathathu ukuthuthukisa ukuthembeka nokuphepha kokusebenza kwedivayisi yesilawuli esivusa amadlingozi ngokwandisa ukutshalwa kwezimali kwehadiwe. Imodi yokusebenza kwamayunithi amathathu ingahlukaniswa ngemodi yokusebenza yokulinda yamayunithi amathathu kanye nemodi yokusebenza yokuvota okubili - ngaphandle - kokuthathu.

I-2）Imodi yokusebenza yokulinda yamayunithi amathathu

Isimiso sokusebenza sale modi ukuthi ngaphezu kokushintsha okuzenzakalelayo phakathi kweYunithi A neYunithi B njengezipele zodwa, iyunithi C eyisipele nayo iyaklanywa. Uma kokubili Iyunithi A kanye neyunithi B zehluleka, Iyunithi C ingashintshela ngokuzenzakalelayo ekusebenzeni kwe-inthanethi. Iyunithi C ingaklanywa ukuthi ibe nemisebenzi efanayo neyeyunithi A kanye neyunithi B. Kodwa-ke, ngokuvamile, amathuba okuhluleka kanyekanye kweyunithi A kanye neyunithi B mancane uma kuqhathaniswa. Ukwenza uhlelo lube lula, i-Unit C ingaklanywa ukuthi ibe nemisebenzi elula yokulawula ukuvusa inkanuko, isibonelo, ukuqinisekisa kuphela ukuthi ijeneretha iyaqhubeka nokusebenza kumodi yokusebenza yamanje (ngesandla) eshukumisayo.

I-3）Imodi yokusebenza yokuvota kwababili kwabathathu

Kule modi yokusebenza, womathathu amayunithi asebenza ku-inthanethi. Amasethi amathathu okulawula athola amasiginali wokufaka angaphandle afanayo, futhi isoftware yawo nezakhiwo zehardware ziyafana ngokuphelele. Uma imiphumela yokukhiphayo yamasethi amabili kwamathathu ezilawuli ivumelana, lo mphumela ophumayo uthunyelwa njengokuphumayo kwesilawuli se-digital excitation regulator into elawulwayo engxenyeni yesistimu yokuvusa amadlingozi. Uma amayunithi amabili kwamathathu ehluleka, isilawuli se-digital excitation asikwazi ukusebenza. Ngakho-ke, imodi yokusebenza yokuvota okubili - ngaphandle - kokuthathu ayikuthuthukisi ukwethembeka uma kuqhathaniswa nemodi yokusebenza lapho amayunithi amabili asetshenziswa njengezipele zodwa. Inzuzo yemodi yokuvota emibili - ngaphandle - kokuthathu isekuthuthukisweni kokuphepha kokusebenza kwedivayisi, okungukuthi, ingagwema kangcono ukukhishwa kwamasiginali okulawula ukuvusa amadlingozi, ngaleyo ndlela igweme izenzakalo ezifana nokungahambi kahle - ukuvuthwa nokuphuma - kokulawula kwejeneretha.
