6-35kV High voteji Static var jenereta

SVG (Static Var Generator) ndi chipangizo chamakono cholipirira magetsi chomwe chimagwiritsa ntchito njira yosinthira pawokha. Ndiukadaulo waposachedwa kwambiri pantchito yolipirira mphamvu zogwiritsa ntchito, yomwe imadziwikanso kuti STATCOM (Static Synchronous Compensator).

Chipangizo cha SVG dynamic reactive reactive power compensation chomwe chimapangidwa ndi kampani yathu chili ndi ubwino pakuyankhira liwiro, mphamvu ya gridi yokhazikika, kutayika kwa makina, kuwonjezereka kwa mphamvu yotumizira, kupititsa patsogolo malire amagetsi osakhalitsa, kuchepetsa ma harmonics, ndi kuchepa kwa mapazi.

Kukula kwa SVG dynamic reactive reactive power compensation device kumadalira mphamvu yaukadaulo ya kampani yathu, ndipo imagwiritsa ntchito bwino luso lazopangapanga komanso luso lamakampani opanga magetsi, kugwiritsa ntchito mokwanira kafukufuku, kapangidwe, kupanga, ndi kuyesa luso. . Kampani yathu ili ndi kulumikizana kwapakatikati pamaphunziro ndi mgwirizano waukadaulo ndi mabungwe ofufuza odziwika bwino komanso makampani amagetsi mkati ndi kunja. Ndife okonzeka kugwirira ntchito limodzi ndi ogwiritsa ntchito kupititsa patsogolo mphamvu yamagetsi a gridi yamagetsi ndi luso lamakono ndi zinthu zamtengo wapatali, ndikuthandizira kusunga mphamvu, kuchepetsa kugwiritsa ntchito, ndi kupanga chitetezo m'magulu opangira magetsi, ogulitsa, ndi ogwiritsira ntchito.

※ Magawo oyambitsa ndi kuyang'anira amapangidwa ndi kupatukana kwa gawo lodziyimira pawokha, ndi liwiro lachangu komanso luso loletsa kusokoneza;

※ Tekinoloje yowunikira mphamvu yokhazikika yotengera nthano yamphamvu yanthawi yomweyo;

※ DC mbali voliyumu kuwongolera mphamvu;

※ Ntchito zonse zachitetezo;

Dera lodzipatulira la IGBT loyendetsa galimoto limatsimikizira kudalirika kwa IGBT kutsekedwa kwafupipafupi ndikuyika chidziwitso cha nthawi yeniyeni yowunikira ku machitidwe apamwamba;

※ Maulalo amaketani amapangidwa kuti azidzitengera okha mphamvu, kuonetsetsa kudalirika kwakukulu;

Mapangidwe amtundu wa unyolo amakwaniritsa zofunikira za kudalirika kwakukulu kwa dongosololi ndipo n'zosavuta kusunga;

※ Kugwiritsa ntchito mipiringidzo yamkuwa yopakidwa kumakwaniritsa zofunikira za IGBT zoyambitsa pafupipafupi;

Nthawi yoyankha imatha kufika 5ms.

※ Itha kupereka chiwongola dzanja chopitilira, chosalala, champhamvu, komanso chofulumira kuchokera ku inductive kupita ku capacitive;

※ Kutha kuthetsa vuto la kusalinganika kwa katundu;

※ Makhalidwe omwe alipo, zotulutsa zomwe sizimakhudzidwa ndi magetsi a basi;

※ Osakhudzidwa ndi magawo a impedance

① Dongosolo lopanga mphamvu zamphepo

Kukayikitsa kwa zida zamphepo ndi mawonekedwe ogwiritsira ntchito ma turbines amphepo pawokha kumayambitsa kusinthasintha kwa mphamvu yotulutsa yamagetsi opangira mphepo, zomwe zimadzetsa mavuto monga ma grid olumikizidwa ndi mphamvu yamagetsi, kupatuka kwamagetsi, kusinthasintha kwamagetsi, ndi kuphulika. Kwa minda yayikulu yamphepo yamphepo, zovuta zokhazikika zikadalipo zikalumikizidwa ndi dongosololi, ndipo machitidwe osinthira mphamvu amalipiro amafunikira; Kumbali inayi, kusinthasintha kwamagetsi amagetsi kumathanso kukhudza momwe mafani amagwirira ntchito. Kugwiritsa ntchito zida zolipirira mphamvu zamagetsi za SVG dynamic reactive power m'mafamu amphepo sikungangokwaniritsa zofunikira za mphamvu yamagetsi, kusinthasintha kwamagetsi, komanso kusuntha kwamakina ophatikizira mphamvu yamphepo, komanso kumachepetsa kusokonezeka kwa makina pamagetsi opangira mphepo.

② Katundu wina wolemetsa wamafakitale monga zonyamula migodi ya malasha

Zinthu zina zolemetsa zamakampani monga ma hoist a migodi ya malasha zidzakhala ndi zotsatirazi pa gridi yamagetsi panthawi yogwira ntchito;

(1) Kupangitsa kutsika kwamagetsi ndi kusinthasintha kwa gridi yamagetsi;

(2) Mphamvu yochepa;

(3) Chipangizo chotumizira chidzatulutsa ma harmonics owopsa.

Kuyika SVG dynamic reactive reactive power compensation device kumatha kuthetsa bwino mavutowa.

③ Ng'anjo yamagetsi yamagetsi

Monga katundu wopanda mzere wolumikizidwa ndi gridi yamagetsi, ng'anjo zamagetsi zamagetsi zimakhala ndi zovuta zingapo pagulu lamagetsi, makamaka kuphatikiza:

(1) Kuyambitsa kusalinganika kwakukulu kwa magawo atatu mu gridi yamagetsi, zomwe zimapangitsa kuti pakhale kusanja bwino;

(2) Kupanga ma harmonics apamwamba, pakati pawo pali kugwirizana wamba wa 2 ndi 4 ngakhale harmonics ndi 3, 5, 7 wosamvetseka harmonics, zomwe zimachititsa kuti voteji kupotoza kukhala zovuta;

(3) Pali kwambiri voteji flicker;

(4) Mphamvu zochepa.

Kugwiritsa ntchito SVG dynamic reactive reactive power compensation device kumatha kuthetsa mavuto omwe ali pamwambawa, kulipira mwachangu mabasi okhazikika, kukonza zokolola, kuchepetsa kusinthasintha kwamagetsi ndi kuphulika, ndipo ntchito yolipirira magawo olekanitsa imatha kuthetsa kusalinganika kwa magawo atatu chifukwa cha ng'anjo ya arc.

④ Mphero yozungulira

Mphamvu yamagetsi yopangidwa ndi mphero imakhala ndi zotsatirazi pa gridi yamagetsi:

(1) Kupangitsa kusinthasintha kwamagetsi mu gridi yamagetsi, muzovuta kwambiri zomwe zimapangitsa kuti zida zamagetsi zisagwire bwino ntchito ndikuchepetsa kupanga;

(2) Kuchepetsa mphamvu;

(3) Chipangizo chotumizira katunducho chidzapanga ma harmonics owopsa, omwe angayambitse kusokoneza kwakukulu kwa magetsi. Kuyika SVG dynamic reactive reactive power compensation device kumatha kuthetsa mavuto omwe ali pamwambawa, kukhazikika mphamvu ya basi, kuthetsa kusokoneza kwa harmonic, ndikuwongolera mphamvu yamagetsi.

⑤ Poyimitsa magetsi (66/110kV)

Chipangizo cha SVG dynamic reactive power compensation chitha kubweza mwachangu komanso molondola mphamvu ya capacitive komanso inductive reactive. Ngakhale kukhazikika kwamagetsi amabasi ndikuwongolera mphamvu yamagetsi, kumathetsa bwino vuto la kubwezeredwa kwamphamvu kwamphamvu. Mukakhazikitsa chipangizo chatsopano cha SVG dynamic reactive power compensation, banki yomwe ilipo yokhazikika ya capacitor ndi thyristor controlled reactor (TCR) ingagwiritsidwe ntchito mokwanira kuti mupeze zotsatira zabwino ndi ndalama zochepa, kukhala njira yabwino kwambiri yopititsira patsogolo mphamvu zamagetsi m'madera. grid yamagetsi.

⑥ Kutumiza mphamvu mtunda wautali

Kuyika kwa SVG dynamic reactive reactive power compensation devices pa high-voltage, high-power, ndi mizere yotumizira mphamvu yakutali imatha kupititsa patsogolo ntchito yotumizira ndi kugawa kwamagetsi.
