Uchungechunge lwe-HYSVC idivayisi yesihlungi sesinxephezelo samandla asebenzayo anamandla kagesi aphezulu

incazelo yomkhiqizo

Eziyinhloko yilezi:
●Kunokuguquguquka okukhulu kwamandla kagesi kanye nokucwayiza.
● Inani elikhulu lama-harmonics aphezulu akhiqizwa: isithando somlilo se-arc sikagesi silawulwa yi-oda eliphansi njenge-2 ~ 7;isilungisi kanye nemithwalo yokuguqula imvamisa ngokuyinhloko ingu-5, 7. 11, no-13.
●Banga ukungalingani okukhulu kwezigaba ezintathu kugridi yamandla, okuholela ekulandeleni okunegethivu kwamanje.
●Isici samandla aphansi siholela ekulahlekeni kwamandla.

Indlela yokuxazulula ngokuphelele izinkinga ezingenhla ukuthi umsebenzisi kufanele afake i-dynamic var compensator (SVC) enesivinini sokuphendula esisheshayo.I-voltage yegridi, ukuthuthukisa ukusebenza kahle kokukhiqiza, nokunciphisa imiphumela yokucwayiza.Umsebenzi wesinxephezelo sokuhlukaniswa kwesigaba we-svc ungaqeda ukungalingani kwezigaba ezintathu okubangelwa umthwalo ongalingani, futhi idivayisi yokuhlunga ingasusa ama-harmonic e-oda eliphezulu eyingozi futhi ithuthukise ikhwalithi yamandla, futhi ithuthukise isici samandla ngokunikeza amandla asebenzayo e-capacitive ohlelweni.

imodeli yomkhiqizo

Incazelo Yemodeli

I-SVC ihlukaniswe yaba izinhlobo ezimbili: i-SVC emaphakathi kanye ne-SVC esabalalisiwe
I-SVC ephakathi nendawo ngokuvamile ifakwa ebhasini eline-voltage ephezulu esiteshini esingaphansi noma egumbini lokusabalalisa amandla, futhi ugesi wayo ngokuvamile ngu-6kV~35kV.Isinxephezelo esimaphakathi somthwalo waso sonke isitshalo sisetshenziswa eShayina njengamanje.
I-SVC esabalalisiwe ngokuvamile iyasatshalaliswa futhi ifakwe eduze komthwalo womthelela (njengohlangothi lwesibili lwesiguquli esilungisa kabusha), futhi i-voltage yayo iyafana ne-voltage yomthwalo, futhi umthwalo womthelela unxeshezelwa endaweni.Isinxephezelo esisabalalisiwe sinezici zokonga amandla nokunciphisa umthwalo wama-transformer.
Izicelo kanye Nomhlahlandlela Wokukhetha
Lo mkhiqizo usetshenziswa kakhulu ezithandweni zikagesi ze-arc, izigayo eziginqikayo, ama-hoist asemayini, izitimela zikagesi, amapulazi omoya nezinye izikhathi.
● I-voltage ohlangothini lwesibili lwesithando somlilo se-arc kagesi iphansi futhi iyashintshashintsha, futhi i-SVC emaphakathi ngokuvamile isetshenziswa.
●Uma inani lezigayo eziginqikayo kumshini wokugaywa lilincane, ngokuvamile i-SVC esabalalisiwe isetshenziswa, enomphumela omuhle wokonga amandla, i-voltage ezinzile ohlangothini lwesibili lwesiguquli esilungisa izinto, ukusebenza kahle kokukhiqiza okuphezulu, kanye nokutshalwa kwezimali okuncane.
●Uma inani lezigayo eziginqikayo kumshini wokugaywa lilikhulu, i-SVC esabalalisiwe noma i-SVC ephakathi nendawo ingasetshenziswa.I-SVC esabalalisiwe inomphumela omuhle wokonga amandla, i-voltage ezinzile ohlangothini lwesibili lwesiguquli esilungisa kabusha, kanye nokusebenza kahle kokukhiqiza okuphezulu.Ukutshalwa kwezimali okuphezulu okuphakathi kwe-SVC Nakuba umphumela wokonga umbi nakakhulu, kodwa ukutshalwa kwezimali kuncane.
●I-Mine hoist ngokuvamile isebenzisa i-SVC esabalalisiwe kanye nedivayisi yokuhlunga ene-voltage ephezulu.I-SVC esabalalisiwe inxephezela ngokuyinhloko umthwalo womthelela we-hoist, futhi idivayisi yesihlungi se-voltage ephezulu inxephezela eminye imithwalo eguqukayo ezinzile.
●Isistimu yamandla epulazi lomoya ngokuvamile incane, futhi ukwehla kwamandla kagesi kutheminali ye-turbine yomoya kukhulu uma kuqhathaniswa.Kunconywa ukusebenzisa i-SVC esabalalisiwe.

Imingcele Yezobuchwepheshe

Izici zedivayisi
●Ibhange lokuhlunga lilungisiwe, ngakho-ke akusadingeki ukuthi lishintshe ngokuzenzakalelayo ngokuvumelana noshintsho lomthwalo, ngakho ukuthembeka kwalo kukhule kakhulu.
● Landela ngokuzenzakalelayo amapharamitha wesistimu ngokwezinguquko zokulayisha, shintsha ngokuzenzakalelayo i-engeli yokuqalisa ye-TCR, ngaleyo ndlela uguqule amandla okukhiphayo e-TCR.
● Ngokusebenzisa ubuchwepheshe bedijithali be-DSP ethuthukisiwe, isivinini sokusebenza singu-<10ms;ukunemba kokulawula kungu-±0.1 degree.<>
●I-SVC ephakathi nendawo isebenzisa ubuchwepheshe obuthuthukisiwe be-photoelectric trigger, okwenza ukuhlukaniswa kukagesi kagesi aphezulu naphansi futhi ithuthukise ikhono lokunqanda ukuphazamiseka.Ubuchwepheshe bokuvikela i-thyristor BOD bamukelwa ukuvikela ngokushesha nangempumelelo i-thyristor.Ubuchwepheshe bokupholisa amanzi obuhlanzekile busetshenziselwa ukupholisa ngokushesha iqembu le-valve futhi kuqinisekiswe ukusebenza okuthembekile nokusebenza kahle kwe-thyristor.
● Ama-thyristors e-SVC asabalalisiwe awadingi ukuxhunywa ochungechungeni noma ngokuhambisana, futhi ukwethembeka kwawo kuthuthukiswa kakhulu.
I-TCR+FC static low-voltage dynamic reactive power compensation device (SVC) ikakhulukazi yakhiwe izingxenye ezintathu, isihlungi se-FC, i-TCR thyristor control circuit kanye nesistimu yokuvikela yokulawula.Isihlungi se-FC sisetshenziselwa ukuhlinzeka ngesinxephezelo samandla asebenzayo kanye nokuhlunga kwe-harmonic, futhi i-TCR thyristor control reactor isetshenziselwa ukulinganisa amandla asebenzayo e-inductive akhiqizwa ukushintshashintsha komthwalo ohlelweni.Ngokulungisa i-engeli yokudubula ye-thyristor, yamanje egeleza ku-reactor ilawulwa ukuze kuzuzwe injongo yokulawula amandla asebenzayo.Idivayisi ye-SVC ishintsha amandla asebenzayo (amandla asebenzayo e-inductive) we-reactor ngokuya ngokushintsha kwamandla asebenzayo Qn womthwalo, okungukuthi, kungakhathaliseki ukuthi amandla asebenzayo omthwalo ashintsha kanjani, isamba sakho kokubili kufanele sibe njalo. okungaguquki, okulingana nebhange le-capacitor Inani lamandla asebenzayo e-capacitive athunyelwe ngaphandle lenza amandla asebenzayo ama-Q athathwe kugridi engaguquki noma u-0, futhi ekugcineni igcina isici samandla egridi enanini elimisiwe, futhi i-voltage icishe ingabi namandla. liyashintshashintsha, ukuze kufezwe inhloso yesinxephezelo samandla asebenzayo.Cindezela ukuguquguquka kwamandla kagesi wesistimu kanye nokucwayiza okubangelwa ukushintshashintsha komthwalo
Ijika lokushaja, i-Qr iyijika lamandla asebenzayo elimuncwa i-reactor ku-SVC.Umfanekiso 2 ungaphansi kwe-CR+FC static
Umdwebo wohlelo lwe-dynamic var compensator (SVC).

Amanye amapharamitha

Imibandela Yokusebenzisa
● Ukuphakama kwendawo yokufaka nokusebenza ngokuvamile akweqi ku-1000m, futhi uhlobo lwe-plateau luyadingeka uma ludlula u-1000m, okufanele lucaciswe lapho ku-oda.
●Izinga lokushisa elizungezile lendawo yokufaka nokusebenza akufanele lidlule -5°C~+40°C ekufakweni kwangaphakathi kanye -30°C~+40°C ekufakweni kwangaphandle.
●Akukho ukudlidliza komshini okunzima, akukho gesi nesitimu esiyingozi, akukho uthuli oluqhumayo noma oluqhumayo endaweni yokufaka nokusebenza.

Ubukhulu

Ukwesekwa kwezobuchwepheshe kanye nesevisi
●Isilinganiso somthwalo
Kuhlanganisa nenani lesizukulwane samanje se-harmonic semithwalo ehlukahlukene engaqondile, izinga lokuhlanekezela le-waveform ye-sinusoidal yevolthi yebhasi yokuphakela amandla, i-harmonics yangemuva yesistimu yamandla, ukushintshashintsha kwamandla kagesi kanye nokucwayiza okubangelwa umthelela wamandla asebenzayo, njll.
