HYSVC mndandanda wapamwamba voteji zotakataka zotakasika mphamvu zolipira fyuluta chipangizo

Mafotokozedwe Akatundu

Yaikulu ndi:
● Pali kusinthasintha kwakukulu kwa magetsi komanso kusinthasintha.
● Chiwerengero chachikulu cha ma harmonics apamwamba amapangidwa: ng'anjo yamagetsi yamagetsi imayang'aniridwa ndi malamulo otsika monga 2 ~ 7;katundu wokonzanso ndi kutembenuka pafupipafupi amakhala makamaka 5, 7. 11, ndi 13.
●Kuchititsa kuti magawo atatu asamayende bwino mu gridi yamagetsi, zomwe zimapangitsa kuti pakhale kusanja bwino.
● Kuchepa kwa mphamvu kumapangitsa kuti magetsi awonongeke.

Njira yothetsera mavuto omwe ali pamwambawa ndi yakuti wogwiritsa ntchito ayenera kukhazikitsa dynamic var compensator (SVC) ndi liwiro lachangu.Mphamvu yamagetsi ya gridi, kuwongolera magwiridwe antchito, ndikuchepetsa zotsatira za flicker.Ntchito yogawaniza gawo la svc imatha kuthetsa kusalinganika kwa magawo atatu chifukwa cha katundu wosagwirizana, ndipo chipangizo chojambulira chimatha kuthetseratu ma harmonics owopsa komanso kuwongolera mphamvu yamagetsi, ndikuwongolera mphamvu yamagetsi popereka mphamvu yogwira ntchito ya capacitive ku dongosolo.

SVC imagawidwa m'mitundu iwiri: SVC yapakati ndi SVC yogawidwa
SVC yapakati nthawi zambiri imayikidwa pa basi yothamanga kwambiri m'chipinda chocheperako kapena chipinda chogawa magetsi, ndipo voteji yake nthawi zambiri imakhala 6kV ~ 35kV.Malipiro apakati pa katundu wa mbewu yonse amagwiritsidwa ntchito pano ku China.
SVC yogawidwa nthawi zambiri imagawidwa ndikuyikidwa pafupi ndi katundu wokhudzidwa (monga mbali yachiwiri ya transformer rectifier), ndipo mphamvu yake imakhala yofanana ndi mphamvu yamagetsi, ndipo mphamvu zake zimalipidwa kwanuko.Malipiro ogawidwa ali ndi makhalidwe opulumutsa mphamvu ndi kuchepetsa katundu wa ma transformer.
Mapulogalamu ndi Kusankha Guide
Izi zimagwiritsidwa ntchito makamaka mu ng'anjo zamagetsi zamagetsi, mphero zogubuduza, ma hoist amigodi, ma locomotives amagetsi, minda yamphepo ndi zina.
● Magetsi kumbali yachiwiri ya ng'anjo yamagetsi yamagetsi ndi yotsika komanso yosinthika, ndipo SVC yapakati imagwiritsidwa ntchito nthawi zambiri.
● Pamene kuchuluka kwa mphero mu mphero yogudubuza ndi yaying'ono, SVC yogawidwa imagwiritsidwa ntchito, yomwe imakhala ndi mphamvu yabwino yopulumutsira mphamvu, mphamvu yokhazikika pambali yachiwiri ya thiransifoma yokonzanso, kupanga kwambiri, ndi ndalama zochepa.
● Pamene chiwerengero cha mphero zogudubuza ndi zazikulu, SVC yogawidwa kapena SVC yapakati ingagwiritsidwe ntchito.SVC yogawidwa imakhala ndi mphamvu yabwino yopulumutsira mphamvu, magetsi okhazikika kumbali yachiwiri ya chosinthira chosinthira, komanso kupanga bwino kwambiri.High ndalama centralized SVC Ngakhale mphamvu zopulumutsa mphamvu ndi pang'ono kuipa, koma ndalama ndi zochepa.
●Mine hoist nthawi zambiri imagwiritsa ntchito makina a SVC komanso makina osefera othamanga kwambiri.SVC yogawidwa makamaka imalipiritsa zomwe zimakhudzidwa ndi chokwezera, ndipo chipangizo chojambulira champhamvu kwambiri chimalipira katundu wokhazikika wokhazikika.
● Dongosolo la magetsi la famu yamphepo nthawi zambiri limakhala laling'ono, ndipo kutsika kwa magetsi pagawo la turbine yamphepo kumakhala kwakukulu.Ndikofunikira kugwiritsa ntchito SVC yogawidwa.

Magawo aukadaulo

Zipangizo Zamakono
● Banki ya fyuluta imakhazikitsidwa, kotero sichifunikanso kusinthana molingana ndi kusintha kwa katundu, kotero kudalirika kwake kumawonjezeka kwambiri.
● Londolerani magawo a dongosolo molingana ndi kusintha kwa katundu, sinthani njira yoyambira ya TCR, potero mumasintha mphamvu ya TCR.
● Pogwiritsa ntchito luso lamakono la digito la DSP, liwiro la ntchito ndi <10ms;kulondola kowongolera ndi ± 0.1 digiri.<>
● Centralized SVC imagwiritsa ntchito luso lapamwamba la photoelectric trigger, lomwe limapangitsa kuti magetsi azikhala otsika komanso otsika kwambiri komanso amathandiza kuti asasokonezedwe.Tekinoloje yachitetezo cha BOD thyristor imatengedwa kuti iteteze mwachangu komanso moyenera thyristor.Ukadaulo wozizira kwambiri wamadzi ozizira umagwiritsidwa ntchito kuziziritsa mwachangu gulu la valavu ndikuwonetsetsa kuti ntchito yodalirika ndi yodalirika ya thyristor.
● Ma thyristors a SVC ogawidwa safunikira kulumikizidwa mndandanda kapena mofanana, ndipo kudalirika kwawo kumakhala bwino kwambiri.
TCR + FC static low-voltage dynamic reactive power compensation device (SVC) imakhala ndi magawo atatu, fyuluta ya FC, TCR thyristor control circuit ndi control system.Fyuluta ya FC imagwiritsidwa ntchito popereka chipukuta misozi champhamvu komanso kusefa kwamtundu wa harmonic, ndipo chowongolera cha TCR thyristor control reactor chimagwiritsidwa ntchito kulinganiza mphamvu yochititsa chidwi yopangidwa ndi kusinthasintha kwa katundu mudongosolo.Ndi kusintha kuwombera ngodya ya thyristor, panopa akuyenda riyakitala amalamulidwa kukwaniritsa cholinga kulamulira zotakasika mphamvu.Chipangizo cha SVC chimasintha mphamvu yogwira ntchito (inductive reactive power) ya riyakitala malinga ndi kusintha kwa mphamvu yogwira ntchito Qn ya katunduyo, ndiye kuti, ziribe kanthu momwe mphamvu yowonongeka ya katunduyo isinthira, chiwerengero cha ziwirizi chiyenera kukhala nthawi zonse. nthawi zonse, yomwe ili yofanana ndi banki ya capacitor Mtengo wa mphamvu ya capacitive reactive yomwe imatumizidwa imapangitsa kuti mphamvu zowonongeka za Qs zitengedwe kuchokera ku gridi nthawi zonse kapena 0, ndipo pamapeto pake zimasunga mphamvu ya gululi pamtengo wokhazikitsidwa, ndipo voteji imakhala yovuta kwambiri. zimasinthasintha, kuti akwaniritse cholinga cha chipukuta misozi champhamvu.Tsimikizirani kusinthasintha kwamagetsi ndi kusuntha komwe kumachitika chifukwa cha kusinthasintha kwa katundu
Charge curve, Qr ndiye njira yokhotakhota yamagetsi yomwe imatengedwa ndi riyakitala mu SVC.Chithunzi 2 ndi chotsika cha CR + FC static
Chithunzi chojambula cha dynamic var compensator (SVC).
