6-35kV Umuvuduko mwinshi Static var Generator

SVG (Static Var Generator) nigikoresho kigezweho cyindishyi zikoresha imbaraga zikoresha ubwikorezi bwo guhindura icyiciro cyumuzunguruko. Nubuhanga bugezweho mubijyanye nindishyi zingufu zamashanyarazi, zizwi kandi nka STATCOM (Static Synchronous Compensator).

Igikoresho cya SVG gifite imbaraga zishyurwa nisosiyete yacu gifite ibyiza mubisubizo byihuta, voltage ihamye ya gride, kugabanya igihombo cya sisitemu, kongera ingufu zogukwirakwiza, kongera ingufu za voltage yinzibacyuho, kugabanya guhuza, no kugabanya ibirenge.

Iterambere rya SVG dinamike igikoresho cyindishyi zingufu zishingiye kumbaraga zikomeye za tekiniki yikigo cyacu, kandi ikoresha byimazeyo tekinoloji yateye imbere hamwe nuburambe bwibikorwa byumusaruro witsinda ryamatsinda munganda zingufu, ukoresha byimazeyo ubushakashatsi bwuzuye, gushushanya, gukora, nubushobozi bwo gupima . Isosiyete yacu ifite amasano ya hafi nubufatanye bwa tekiniki ninzego zubushakashatsi zizwi hamwe n’amasosiyete y’amashanyarazi haba mu gihugu ndetse no ku rwego mpuzamahanga. Twiteguye gufatanya n’abakoresha mu kuzamura ubwiza bw’amashanyarazi hifashishijwe ikoranabuhanga rigezweho n’ibicuruzwa byujuje ubuziranenge, kandi tugira uruhare mu kubungabunga ingufu, kugabanya ibicuruzwa, no kubyaza umusaruro umutekano mu bijyanye n’amashanyarazi, gutanga, no gukoresha.

Unit Ibice bikurura no gukurikirana byateguwe hamwe no gutandukanya ibyiciro byigenga, bifite umuvuduko wihuse nubushobozi bukomeye bwo kurwanya-kwivanga;

Technology Ikorana buhanga ryerekana imbaraga zishingiye kubitekerezo byihuse;

DC Kugenzura impagarike ya DC kuruhande;

Imikorere yuzuye yo kurinda;

Umushoferi wabigenewe wa IGBT yemeza ko IGBT ihagarikwa cyane kandi igashyiraho amakuru yo kugenzura imiterere-nyayo kuri sisitemu yo hejuru yo kugenzura;

Guhuza urunigi rwateguwe hamwe no gusarura ingufu, byemeza ko byizewe cyane;

Igishushanyo mbonera cyimiterere yuruhererekane cyujuje ibisabwa byo kwizerwa cyane kwa sisitemu kandi byoroshye kubungabunga;

※ Gushyira mu mbaho ​​z'umuringa zegeranye zujuje ibisabwa bya IGBT inshuro nyinshi;

Igihe cyo gusubiza kirashobora kugera kuri 5ms.

※ Irashobora gutanga amashanyarazi ahoraho, yoroshye, afite imbaraga, kandi yihuse yingufu zivuye mumashanyarazi kugeza kubushobozi;

Abishoboye gukemura ikibazo cyo kutaringaniza imitwaro;

Source Inkomoko yiki gihe iranga, ibisohoka reaction itagerwaho na voltage ya bisi;

※ Ntabwo yunvikana ibipimo bya sisitemu

System Sisitemu yo kubyara ingufu z'umuyaga

Kutamenya neza umutungo wumuyaga nibiranga imikorere yumuyaga ubwabyo bitera ihindagurika ryimbaraga ziva mumashanyarazi yumuyaga, biganisha kubibazo nka gride itujuje ibyangombwa ihuza amashanyarazi, gutandukana kwa voltage, ihindagurika rya voltage, na flicker. Ku murima munini w’umuyaga, ibibazo byumutekano biracyahari iyo bihujwe na sisitemu, kandi hakenewe uburyo bwo gutanga ingufu zingirakamaro; Kurundi ruhande, ihindagurika muri sisitemu ya voltage nayo irashobora kugira ingaruka kumikorere isanzwe yabafana. Ikoreshwa rya SVG dinamike yingufu zishyurwa mumashanyarazi yumuyaga ntishobora gusa kuzuza ibisabwa byingufu zamashanyarazi, ihindagurika ryumuvuduko, hamwe no guhinduranya amashanyarazi yumuyaga, ariko kandi bigabanya ingaruka ziterwa nihungabana rya sisitemu kuri turbine.

② Indi mitwaro iremereye yinganda nko kuzamura amakara

Indi mitwaro iremereye yinganda nko kuzamura amakara izagira ingaruka zikurikira kuri gride yamashanyarazi mugihe ikora;

(1) Gutera kugabanuka kwa voltage no guhindagurika mumashanyarazi;

(2) Impamvu nke;

(3) Igikoresho cyohereza kizatanga umusaruro mubi wo murwego rwo hejuru.

Kwinjiza ibikoresho bya SVG dinamike reaction yingufu zishobora gukemura neza ibibazo byavuzwe haruguru.

Itanura ryamashanyarazi arc

Nkumutwaro utari umurongo uhujwe na gride ya power, itanura ryamashanyarazi arc rizagira urukurikirane rwingaruka mbi kumashanyarazi, cyane cyane harimo:

.

.

(3) Hariho flicker ikabije;

(4) Impamvu nke.

Gukoresha ibikoresho bya SVG dinamike yingufu zishobora gukemura ibibazo byavuzwe haruguru, kwishyura byihuse amashanyarazi ya bisi ihamye, kuzamura umusaruro, kugabanya ihindagurika rya voltage na flicker, kandi imikorere yindishyi yo gutandukanya icyiciro irashobora gukuraho ubusumbane bwibyiciro bitatu biterwa nitanura rya arc.

Mill Uruganda ruzunguruka

Ingaruka yingufu zituruka kumashanyarazi izagira ingaruka zikurikira kuri gride y'amashanyarazi:

(1) Gutera ihindagurika rya voltage mumashanyarazi, mubihe bikomeye bitera ibikoresho byamashanyarazi gukora nabi no kugabanya umusaruro;

(2) Kugabanya ibintu by'ingufu;

. Gushiraho ibikoresho bya SVG bigenda byishyurwa birashobora gukemura neza ibibazo byavuzwe haruguru, guhagarika ingufu za bisi, gukuraho kwivanga, no kunoza ibintu.

Sub Gusimbuza amashanyarazi (66 / 110kV)

Igikoresho cya SVG gifite imbaraga zo kwishura imbaraga zirashobora kwishura byihuse kandi neza imbaraga zidasanzwe kandi zidasanzwe. Mugihe uhagaritse ingufu za bisi no kunoza ibintu byamashanyarazi, bikemura neza kandi byoroshye gukemura ikibazo cyingufu zisubira inyuma. Mugihe ushyizeho ibikoresho bishya bya SVG dinamike yingufu zamashanyarazi, banki isanzwe ihamye ya capacitor hamwe na thyristor igenzurwa na reaction (TCR) irashobora gukoreshwa neza kugirango igere kubisubizo byiza hamwe nishoramari rito, bibe uburyo bwiza bwo kuzamura ubwiza bwamashanyarazi mukarere amashanyarazi.

Distance Gukwirakwiza amashanyarazi maremare

Kwishyiriraho ibikoresho bya SVG dinamike yibikoresho byindishyi zumuriro hejuru yumuriro mwinshi, imbaraga nyinshi, hamwe nintera ndende yohereza amashanyarazi birashobora kunoza cyane imikorere yo gukwirakwiza no gukwirakwiza sisitemu yamashanyarazi.
