Mafotokozedwe Akatundu

Pakalipano, gawo lamagetsi limayika kufunikira kwakukulu pakupulumutsa mphamvu ndi kuchepetsa kutaya.Kuyambira pakuwongolera mphamvu zamagetsi ndi mphamvu zogwiritsa ntchito, ndalama zambiri zayikidwa kuti zikhazikitse mapulogalamu ambiri owongolera mphamvu zamagetsi.VQC, chosinthira chapampopi chodzaza, banki yamphamvu yolipirira shunt capacitor ndi zida zina, mawonekedwe amagetsi asinthidwa bwino.Komabe, chifukwa chakubwerera m'mbuyo kwa njira zosinthira mphamvu ndi zovuta monga kuchulukira kwamagetsi, kuchulukirachulukira, komanso nthawi yayitali yamoyo pakugwira ntchito kwa ma capacitors, pulogalamu yamagetsi ndi yogwira ntchito yoyang'anira mphamvu sizingagwire ntchito yake, ndipo sizingasungire nthawi zonse zizindikiro zomwe zimafunikira mphamvu yamagetsi ndi magetsi. zotakataka mphamvu.Zopindulitsa zachuma ndi zamakono sizingatheke, ndipo kuthekera kwa zipangizo sikungagwiritsidwe ntchito mokwanira.

Poyang'ana kumbuyo kwa voteji ndi njira zosinthira mphamvu zamagetsi, kampani yathu yapanga mtundu watsopano wamagetsi ocheperako komanso kachipangizo kamene kamasinthira mphamvu pazida zotengera matekinoloje atsopano kunyumba ndi kunja.Mphamvu yotulutsa imasinthidwa ndikusintha voteji pamalekezero onse a capacitor, yomwe imathetsa mavuto a overvoltage ndi inrush pano pakugwira ntchito kwa capacitor, ndikusintha kusintha kwa hysteresis kukhala kusintha kwanthawi yeniyeni.Magetsi a substation ndi reactive power automatic adjustment athanso kusintha chokhazikika cha parallel capacitor kukhala chida cholipirira mphamvu chosinthika.Kuchulukitsidwa ndi kugwiritsa ntchito zida izi kumatha kusintha bwino kasamalidwe ka voteji ndi mphamvu yogwira ntchito, yomwe imatha kuchepetsa kutayika kwa gridi yamagetsi, kuwongolera mphamvu yamagetsi, kukonza magwiridwe antchito otetezeka a zida, kuonjezera phindu lazachuma lamakampani opanga magetsi. , ndi kupititsa patsogolo mphamvu zamagetsi popanda kumanga nyumba zatsopano zamagetsi.Thandizani kuthetsa vuto la kuchepa kwa magetsi m'nyumba.

kuchuluka kwa ntchito

Zogulitsazo ndizofunikira kwambiri pamagawo onse okhala ndi magetsi a 6KV ~ 220KV, ndipo zimayikidwa pa mabasi a 6KV/10KV/35KV a malowo.Zogulitsa zimagwiritsidwa ntchito kwambiri pamakina amagetsi, zitsulo, malasha, petrochemical ndi mafakitale ena kuti apititse patsogolo mphamvu yamagetsi, kuwonjezera mphamvu yamagetsi, ndikuchepetsa kutayika kwa mzere.

Chipangizo mfundo
Magetsi ndi zotakasika mphamvu zodziwikiratu chida chosinthira chapansi panthaka utenga kugwirizana kokhazikika kwa ma capacitor popanda gulu, ndipo mphamvu yamalipiro ya capacitor imasinthidwa ndikusintha voteji kumapeto onse a capacitor.Malinga ndi mfundo ya Q = 2πfCU2, voliyumu ndi mtengo wa C wa capacitor zimakhalabe zosasinthika, ndipo magetsi pamapeto onse a capacitor amasinthidwa.Kutulutsa kwa mphamvu zotakataka.
Mphamvu zake zotulutsa zimatha kusintha kulondola ndi kuya kwa kayendetsedwe ka magetsi pa (100% ~ 25%) x Q, ndiko kuti, kusintha kulondola ndi kuya kwa ma capacitors kungasinthidwe.
Chithunzi 1 ndi chithunzi cha block cha mfundo yogwirira ntchito ya chipangizocho:

Kapangidwe kachipangizo

Chipangizo chowongolera ma voliyumu chimapangidwa makamaka ndi magawo atatu, omwe ndi chowongolera ma voltage, ma capacitor onse ndi gulu lowongolera magetsi ndi magetsi.Chithunzi 2 ndiye chojambula choyambirira cha chipangizochi:

Voltage regulator: Wowongolera amalumikiza capacitor ku busbar, ndikusintha voteji ya capacitor pansi pamalingaliro owonetsetsa kukhazikika kwa voliyumu ya basi, kuti atsimikizire kuti mphamvu yotulutsa ya capacitor ikukwaniritsa zofunikira za dongosolo.Voltage ndi reactive power control panel: Malinga ndi zomwe zikulowetsa panopa ndi ma siginecha amagetsi, chigamulo chapampopi chimachitidwa, ndipo malamulo amaperekedwa kuti asinthe matepi akuluakulu a thiransifoma pagawo laling'ono kuti asinthe voteji kuti atsimikizire kuthamanga kwamagetsi a basi.Sinthani mphamvu yotulutsa mphamvu yamagetsi owongolera kuti musinthe mphamvu yotulutsa mphamvu ya capacitor.Ndipo ili ndi mawonekedwe ofananirako ndi ntchito zazizindikiro.Capacitive reactive mphamvu gwero la capacitor wathunthu seti.

Ubwino wa chipangizocho

a.Poyerekeza ndi mtundu wosinthira, gulu limodzi lokha la mabanki a capacitor limatha kulumikizidwa mosadukiza kuti lizindikire liwiro lachisanu ndi chinayi, ndipo kulondola kwa chipukuta misozi ndikwambiri, komwe kumatha kukwaniritsa zofunikira zakusintha kwamphamvu kwadongosolo;
b.Chowongolera chodzivulaza chodzivulaza chokha chimatengedwa kuti chiwongolere kupanikizika, liwiro losintha limakhala lachangu, kusintha kwanthawi yeniyeni kumatha kuchitika, ndipo chipukuta misozi ndi chodabwitsa;
c.Ikhoza kutsekedwa pamagetsi otsika, omwe amachepetsa kwambiri kutseka kwa inrush panopa ndipo amachepetsa mphamvu pa dongosolo ndi capacitors;
d.Poyerekeza ndi kusintha, akhoza kuonetsetsa kuti capacitor ukugwira ntchito pansi pa voteji oveteredwa kwa nthawi yaitali, popanda kusintha overvoltage ndi kukwera mavuto panopa, amene kwambiri kutalikitsa moyo utumiki capacitor;
e.Chipangizocho chili ndi makina apamwamba kwambiri, ntchito zotetezera kwathunthu, kulankhulana kwa digito ndi ntchito zosamalira kutali, ndipo zimatha kukwaniritsa zosowa zosayang'aniridwa ndi zosamalira;
f.Kutayika kowonjezera kumakhala kochepa, 2% yokha ya mphamvu ya capacitor.Pafupifupi gawo limodzi mwa magawo khumi a kutayika kwa SVC;
9. Ma capacitors safunikira kusinthidwa m'magulu, zomwe zimachepetsa zida monga kusintha masinthidwe ndikuphimba malo, ndikusunga ndalama zogulira zomangamanga;
h.Chipangizocho sichimapanga ma harmonics ndipo sichidzayambitsa kuipitsidwa kwa harmonic ku dongosolo;
ndi.Pakakhala riyakitala yotsatizana, kuchuluka kwa giya lililonse kumatha kutsimikiziridwa kukhala kosasintha;
