6-35kV High voltage Static var Jenareta

SVG (Static Var Jenareta) chishandiso chemazuva ano chekugadzirisa magetsi chinoshandisa chega chega chekuchinja dunhu. Ndiyo ichangoburwa tekinoroji mumunda we reactive simba muripo, inozivikanwawo se STATCOM (Static Synchronous Compensator).

Iyo SVG dynamic reactive reactive power compensation mudziyo inogadzirwa nekambani yedu ine zvakanakira mukupindura kumhanya, yakagadzikana grid voltage, yakaderedzwa system kurasikirwa, yakawedzera simba rekutapurirana, yakagadziridzwa inopfuudza voltage muganho, yakaderedzwa harmonics, uye yakaderedzwa tsoka.

Kuvandudzwa kweSVG dynamic reactive power compensation device kunoenderana nesimba rakasimba rekambani yedu, uye rinoshandisa zvizere tekinoroji yepamusoro uye ruzivo rwekugadzira zvakanakira kambani yeboka muindasitiri yemagetsi, ichishandisa zvizere tsvakiridzo, dhizaini, kugadzira, uye kugona kuyedza. . Kambani yedu ine hukama hwepedyo hwedzidzo uye kubatana kwehunyanzvi nemasangano ane mukurumbira ekutsvagisa uye makambani emagetsi mukati nekunze. Isu takagadzirira kushanda pamwe chete nevashandisi kuvandudza kunaka kwemagetsi emagetsi emagetsi nehunyanzvi hwepamusoro uye zvigadzirwa zvemhando yepamusoro, uye kubatsira mukuchengetedza simba, kuderedza kushandiswa, uye kugadzirwa kwekuchengetedza mumagetsi ekugadzira, kupa, uye mashandisirwo.

※ Iwo anokonzeresa uye ekutarisa mayuniti akagadzirwa ane yakazvimirira chikamu kupatsanurwa, nekukurumidza kushanda kumhanya uye yakasimba yekudzivirira-kukanganisa kugona;

※ Reactive simba rekuona tekinoroji yakavakirwa pakare reactive simba dzidziso;

※ DC side voltage balance control;

※ Zadzisa kuchengetedza mabasa;

Iyo yakatsaurirwa IGBT mutyairi wedunhu inovimbisa kuvimbika kweIGBT yakakwira-frequency disconnection uye kurodha chaiyo-nguva mamiriro ekutarisa ruzivo kune yepamusoro monitoring system;

※ Iwo macheni zvinongedzo akagadzirwa nekuzvikohwa simba, kuve nechokwadi chekuvimbika kwakanyanya;

Iyo modular dhizaini yeketani chimiro inosangana nezvinodiwa zvekuvimbika kwakanyanya kweiyo system uye iri nyore kuchengetedza;

※ Kushandiswa kwemabhawa emhangura akaturikidzana kunosangana nezvinodiwa zveIGBT yakakwirira-frequency trigger;

Nguva yekupindura inogona kusvika 5ms.

※ Inogona kupa inoenderera, yakatsetseka, ine simba, uye inokurumidza reactive simba muripo kubva inductive to capacitive;

※ Kugona kugadzirisa dambudziko rekusaenzana kwemutoro;

※ Yazvino sosi maitiro, inobuda reactive ikozvino isina kukanganiswa nebhazi voltage;

※ Haina hanya kune system impedance paramita

① Mhepo yekugadzira magetsi system

Kusavimbika kwezviwanikwa zvemhepo uye maitiro ekushanda ematurbine emhepo pachawo anokonzera kushanduka kwesimba rinobuda rematurbine emhepo, zvichitungamira kumatambudziko akaita senge isina kukwana grid yakabatana simba chinhu, kutsauka kwevoltage, voltage fluctuation, uye flicker. Kumapurazi makuru emhepo, nyaya dzekugadzikana dzichiripo kana dzakabatana nehurongwa, uye dhizaini yemagetsi ekubhadhara masisitimu inodiwa; Kune rimwe divi, kuchinjika musystem voltage kunogona zvakare kuve nemhedzisiro pane yakajairika kushanda kwe fan. Kushandiswa kweSVG dynamic reactive power compensation devices mumapurazi emhepo hakugone chete kuzadzisa zvinodikanwa zvesimba factor, voltage fluctuation, uye flicker yemhepo yekubatanidza magetsi masisitimu, asi zvakare kuderedza kukanganiswa kwesystem kuvhiringika kwemhepo.

② Zvimwe zvinorema zvemaindasitiri senge marasha emugodhi hoist

Zvimwe zvinorema zvemaindasitiri senge marasha emugodhi hoist zvichave nezvinokonzeresa pane gidhi remagetsi panguva yekushanda;

(1) Kukonzera kudonha kwevoltage uye kushanduka mugedhi remagetsi;

(2) Low power factor;

(3) Chishandiso chekutumira chinoburitsa chinokuvadza chepamusoro-soro harmonics.

Kuisa SVG ine simba reactive simba rekubhadhara mudziyo unogona kunyatsogadzirisa matambudziko ari pamusoro.

③ Magetsi arc choto

Senge isiri-mutsara mutoro wakabatanidzwa kune gidhi remagetsi, magetsi arc furnaces achave nenhevedzano yeakaipa mhedzisiro pane yemagetsi grid, kunyanya kusanganisira:

(1) Kukonzera kusaenzana kwakakomba kwechikamu chetatu mugetsi remagetsi, zvichikonzera kutevedzana kwakashata ikozvino;

(2) Gadzira ma-harmonics epamusoro-soro, pakati pawo pane kugarisana kwakafanana kwe2 uye 4th kunyange harmonics uye 3rd, 5th, 7th odd harmonics, izvo zvinotungamirira kuvhiringidza kwemagetsi kunowedzera kuoma;

(3) Pane yakanyanya voltage flicker;

(4) Low power factor.

Iko kushandiswa kweSVG dynamic reactive power compensation device kunogona kugadzirisa matambudziko ari pamusoro, kukurumidza kutsiva kugadzikana kwebhazi voltage, kunatsiridza kugadzirwa, kuderedza kushanduka kwemagetsi uye flicker, uye chikamu chekuparadzanisa muripo webasa chinogona kubvisa matatu-chikamu kusaenzana kunokonzerwa nechoto chearc.

④ Chigayo

Iyo reactive simba simba rinogadzirwa nechigayo rinotenderedza richava neanotevera maitiro pane yemagetsi grid:

(1) Kukonzera kushanduka kwemagetsi mugedhi remagetsi, muzviitiko zvakakomba zvichikonzera kuti michina yemagetsi ishaye basa uye kuderedza kushanda zvakanaka kwekugadzira;

(2) Power factor kuderedzwa;

(3) Chishandiso chekutumira chemutoro chinoburitsa zvinokuvadza zvakakwirira-odha harmonics, izvo zvinokonzeresa kukanganisa kwakakomba kwegidhi voltage. Kuisa SVG dynamic reactive simba rekubhadhara mudziyo unogona kunyatsogadzirisa matambudziko ari pamusoro, kudzikamisa bhazi voltage, kubvisa harmonic kupindira, uye kunatsiridza simba chinhu.

⑤ Chiteshi chemagetsi (66/110kV)

Iyo SVG ine simba reactive simba rekubhadhara mudziyo unogona kukurumidza uye nemazvo kutsiva capacitive uye inductive reactive simba. Ichiri kudzikamisa bhazi voltage uye kuvandudza simba chinhu, inonyatso uye zviri nyore kugadzirisa dambudziko re reactive simba backflow. Pakuisa mudziyo mutsva weSVG dynamic reactive power compensation, iripo fixed capacitor bank uye thyristor controlled reactor (TCR) inogona kushandiswa zvizere kuwana mibairo yakanaka nekudyara kushoma, ichiva nzira inoshanda kwazvo yekuvandudza kunaka kwemagetsi edunhu. magetsi grid.

⑥ kureba kureba simba kutapurirana

Kuiswa kweSVG dynamic reactive power compensation devices pahigh-voltage, high-power, uye kure-kure-kure ekufambisa magetsi mitsara inogona kuvandudza zvakanyanya kutapurirana uye kugovera kushanda kwesimba remagetsi.
