HYSVC yakatevedzana yakakwira voltage dynamic reactive simba muripo wefirita mudziyo

rondedzero yechigadzirwa

Iwo makuru ndeaya:
●Kune kushanduka kwemagetsi kwakakomba uye flicker.
● Nhamba yakawanda yepamusoro-soro harmonics inogadzirwa: magetsi arc furnace inotungamirirwa nemirairo yakaderera yakadai se2 ~ 7;iyo inogadzirisa uye inoshandura mitoro yakawanda ndeye 5, 7. 11, uye 13.
● Kukonzera zvakakomba zvitatu-chikamu kusaenzana mumagetsi emagetsi, zvichiita kuti pave nenhevedzano yakaipa ikozvino.
● Simba shoma rinoita kuti simba ripere.

Nzira yekugadzirisa zvachose matambudziko ari pamusoro ndeyekuti mushandisi anofanira kuisa dynamic var compensator (SVC) ine kukurumidza kupindura.Grid voltage, kuvandudza kushanda zvakanaka kwekugadzira, uye kuderedza mhedzisiro yeflicker.Iyo chikamu-kuparadzanisa muripo webasa re svc inogona kubvisa iyo-nhatu-chikamu kusaenzana kunokonzerwa nekusagadzikana mutoro, uye iyo sefa mudziyo inogona kubvisa inokuvadza yakakwirira-yakarongeka harmonics uye kuvandudza simba remhando, uye kuvandudza simba chinhu nekupa capacitive reactive simba kune system.

chigadzirwa muenzaniso

Tsanangudzo Yemuenzaniso

SVC yakakamurwa kuita mhando mbiri: yepakati SVC uye yakagoverwa SVC
Iyo centralized SVC inowanzoiswa pa high-voltage bhazi mu substation kana simba rekugovera kamuri, uye simba rayo rinowanzo 6kV ~ 35kV.Muripo wepakati wekuremerwa kwechirimwa chose unoshandiswa muChina.
Distributed SVC inowanzo kugoverwa uye kuiswa padivi peinduru inorema (seyechipiri divi reinogadzirisa transformer), uye magetsi ayo akafanana nevoltage yekuremerwa, uye mutoro wekukanganisa unobhadharwa munharaunda.Distributed compensation ine maitiro ekuchengetedza simba uye kuderedza mutoro we transformers.
Zvishandiso uye Sarudzo Yekutungamira
Ichi chigadzirwa chinonyanya kushandiswa mumagetsi arc furnaces, rolling mill, mine hoist, magetsi locomotives, mapurazi emhepo uye zvimwe zviitiko.
● Mhepo iri padivi rechipiri remagetsi arc furnace yakaderera uye inoshanduka, uye SVC yepakati inowanzoshandiswa.
● Kana nhamba yezvigayo muguyo iri diki, yakagoverwa SVC inowanzo shandiswa, iyo ine simba rakanaka rekuchengetedza simba, kugadzikana kwemagetsi padivi rechipiri re rectifier transformer, kugadzirwa kwakanyanya, uye kushomeka kwekudyara.
● Kana nhamba yezvigayo muchigayo yakakura, yakagoverwa SVC kana centralized SVC inogona kushandiswa.Distributed SVC ine yakanaka-yekuchengetedza simba mhedzisiro, yakagadzikana voltage padivi rechipiri reiyo inoshandura transformer, uye yakakwirira kugadzirwa.Yakakwira mari yepakati SVC Kunyangwe simba rekuchengetedza simba rakanyanya kuipa, asi mari yacho ishoma.
●Mine hoist inowanzotora yakagoverwa SVC pamwe nepamusoro-voltage kusefa mudziyo.Iyo SVC yakagovaniswa inonyanya kubhadhara kukanganiswa kweiyo hoist, uye yakakwira-voltage sefa mudziyo inotsiva iyo yakasara yakagadzikana mitoro ine simba.
●Sitimu yemagetsi yepurazi remhepo kazhinji idiki, uye kudonha kwemagetsi pachiteshi cheturbine yakakura.Inokurudzirwa kushandisa SVC yakagoverwa.

Device Features
● Bhangi resefa rakagadziriswa, saka harichadi kushandura otomatiki maererano nekuchinja kwemutoro, saka kuvimbika kwayo kunowedzera zvakanyanya.
● Otomatiki tarisa maparamendi ehurongwa maererano nekuchinja kwemutoro, otomatiki shandura iyo trigger angle yeTCR, nekudaro ichichinja kubuda kwesimba reTCR.
● Kushandisa tekinoroji yedhijitari yeDSP, kumhanya kwekushanda kuri <10ms;kurongeka kwekutonga kuri ± 0.1 dhigirii.<>
●Centralized SVC inotora teknolojia yepamusoro ye photoelectric trigger teknolojia, iyo inoita yakakwirira uye yakaderera magetsi kuparadzaniswa kwemagetsi uye inovandudza kupesana-kukanganisa kukwanisa.Iyo BOD thyristor kuchengetedza tekinoroji inogamuchirwa nekukurumidza uye zvinobudirira kuchengetedza thyristor.Iyo yakakwirira-yakachena mvura inotonhorera tekinoroji inoshandiswa kukurumidza kutonhora boka revhavha uye kuvimbisa kushanda kwakavimbika uye kugona kwe thyristor.
● Yakagoverwa SVC thyristors haifaniri kubatanidzwa mumutsara kana mukufanana, uye kuvimbika kwavo kunovandudzwa zvikuru.
TCR + FC static low-voltage dynamic reactive power compensation device (SVC) inonyanya kuumbwa nezvikamu zvitatu, FC filter, TCR thyristor control circuit uye control protection system.Iyo FC sefa inoshandiswa kupa capacitive reactive simba muripo uye harmonic kusefa, uye TCR thyristor control reactor inoshandiswa kuenzanisa inductive reactive simba rinogadzirwa nekuremerwa kushanduka muhurongwa.Nekugadzirisa iyo yekupfura angle ye thyristor, ikozvino inoyerera kuburikidza nereactor inodzorwa kuti iwane chinangwa chekutonga reactive simba.Iyo SVC mudziyo inoshandura iyo reactive simba (inductive reactive simba) reiyo reactor zvichienderana nekushandurwa kweiyo reactive simba Qn yemutoro, kureva kuti, zvisinei kuti simba rekuita remutoro rinoshanduka sei, huwandu hwezviviri hunofanirwa kugara huripo. nguva dzose, iyo yakaenzana nebhangi capacitor Kukosha kweiyo capacitive reactive simba inotumirwa kunze inoita kuti reactive simba Qs inotorwa kubva kune grid nguva dzose kana 0, uye pakupedzisira inochengetedza simba regridhi pamutengo wakaiswa, uye magetsi haakwanisi. inochinja, kuitira kuti uwane chinangwa chekugadzirisa simba rekubhadhara.Suppress system voltage fluctuation uye flicker inokonzerwa nekuyerera kwemutoro
