rondedzero yechigadzirwa

Parizvino, chikamu chemagetsi chinoisa kukosha kukuru pakuchengetedza simba uye kuderedza kurasikirwa.Kutanga kubva mukutonga kwemagetsi uye reactive simba, mari yakawanda yakaiswa mukugadzira yakawanda yemagetsi uye reactive simba rekutonga software.VQC, on-load tap changer, Reactive simba muripo shunt capacitor bank uye zvimwe zvishandiso, iyo voltage mhando yakagadziridzwa zvinobudirira.Nekudaro, nekuda kwekudzokera kumashure kwemaitiro ekugadzirisa simba ekugadzirisa uye matambudziko akadai sekuwandisa, overcurrent, uye hupenyu mukushanda kwema capacitors, iyo voltage uye reactive simba manejimendi software haigone kuita basa rayo rakakodzera, uye haigone kugara ichichengetedza inodiwa zviratidzo zvemagetsi uye magetsi. reactive simba.Izvo zvakakodzerwa zvehupfumi uye zvehunyanzvi zvinobatsira hazvigone kuwanikwa, uye kugona kwemidziyo haigone kushandiswa zvizere.

Tiine tarisiro yekudzokera kumashure kwevoltige uye reactive magetsi ekugadzirisa nzira, kambani yedu yakagadzira mhando nyowani ye substation voltage uye reactive magetsi otomatiki gadziriso mudziyo pahwaro hwekutora zvakanyanya matekinoroji matsva kumba nekune dzimwe nyika.Iyo inobuda simba inoshandurwa nekugadzirisa voltage kumagumo ese e capacitor, iyo inogadzirisa matambudziko e overvoltage uye inrush ikozvino mukushanda kwecapacitor, uye inoshandura hysteresis kugadziridzwa kune chaiyo-nguva kugadzirisa.Iyo substation voltage uye reactive simba otomatiki gadziriso mudziyo unogona zvakare kushandura yakagadziriswa parallel capacitor kuita inogadziriswa inductive reactive simba rekubhadhara mudziyo.Kuzivikanwa uye kushandiswa kwechishandiso ichi kunogona kunyatso kuvandudza danho rekutonga remagetsi uye reactive simba, iro rinogona kuderedza zvakanyanya kurasikirwa kwegetsi remagetsi, kuvandudza kunaka kwesimba, kuvandudza mashandiro akachengeteka emidziyo, kuwedzera mabhenefiti ehupfumi emabhizinesi ekupa magetsi. , uye kuvandudza simba rekupa simba pasina kuvaka magetsi matsva.Batsirawo pakugadzirisa mamiriro ezvinhu ekushomeka kwemagetsi mudzimba.

chiyero chekushandisa

Zvigadzirwa zvinonyanya kukodzera mazinga ese ezviteshi zvine voltage mazinga e6KV~220KV, uye anoiswa pamabhazi e6KV/10KV/35KV ezviteshi.Zvigadzirwa zvinoshandiswa zvakanyanya mumagetsi masisitimu, simbi, marasha, petrochemical uye mamwe maindasitiri kuvandudza voltage mhando, kuwedzera simba chinhu, uye kuderedza mutsara kurasikirwa.

Chishandiso musimboti
Iyo voltage uye reactive simba otomatiki gadziriso mudziyo weiyo substation inotora yakagadziriswa yekubatanidza ye capacitor pasina kuunganidza, uye iyo yekuripira kugona kweiyo capacitor inoshandurwa nekushandura voltage kumagumo ese e capacitor.Maererano nenheyo yeQ = 2πfCU2, iyo voltage uye C kukosha kweiyo capacitor inoramba isingachinji, uye mhepo pamagumo maviri eiyo capacitor inoshandurwa.Kubuda kwe reactive simba.
Kuburitsa kwayo simba kunogona kushandura kurongeka uye kudzika kweiyo voltage regulation pa (100% ~ 25%) x Q, ndiko kuti, kurongeka kwekugadzirisa uye kudzika kwema capacitors kunogona kuchinjwa.
Mufananidzo 1 ibhuroka dhizaini yemusimboti wekushanda wechigadzirwa:

Kuumbwa kwemudziyo

Iyo voltage-inodzora otomatiki muripo mudziyo inonyanya kuumbwa nezvikamu zvitatu, zvinoti voltage regulator, iyo yakazara seti ye capacitor uye voltage uye reactive simba rekudzora pani.Mufananidzo 2 ndiyo yekutanga schematic diagiramu yechishandiso:

Voltage regulator: Iyo regulator inobatanidza iyo capacitor kune busbar, uye inoshandura iyo inobuda voltage ye capacitor pasi pechimiro chekuona kugadzikana kwebhasibar voltage, kuitira kuti ive nechokwadi chekuti kubuda kweiyo capacitor kunosangana nezvinodiwa system.Voltage uye reactive simba rekudzora pani: Zvinoenderana neyekupinza yazvino uye magetsi masaini, mutongo wepombi unoitwa, uye mirairo inopihwa kuti igadzirise iyo huru yekuchinja matepi eiyo substation kugadzirisa voltage kuti ive nechokwadi chekupasa kwebhazi voltage.Gadzirisa iyo inobuda voltage yeiyo voltage regulator kuti uchinje reactive simba kubuda kwecapacitor.Uye ine inoenderana kuratidza uye chiratidzo mabasa.Capacitive reactive simba sosi ye capacitor yakazara seti.

Zvakanakira mudziyo

a.Kuenzaniswa nemhando yekuchinja, seti imwe chete yemabhangi e-capacitor inogona kusungirirwa kuti ione kuburitsa mapfumbamwe-kumhanya, uye kurongeka kwemuripo kwakakwira, iyo inogona kusangana nezvinodiwa zvesimba reactive simba shanduko;
b.Iyo on-load inozvikuvadza voltage regulator inogamuchirwa kuti igadzirise kudzvanywa, kukurumidza kugadzirisa kunokurumidza, chaiyo-nguva otomatiki kugadzirisa inogona kuitika, uye muripo wemhedzisiro unoshamisa;
c.Inogona kuvharwa pane yakaderera voltage, iyo inoderedza zvakanyanya kuvhara inrush ikozvino uye zvinobudirira kuderedza kukanganiswa kwehurongwa uye capacitors;
d.Kuenzaniswa nekuchinja, inogona kuve nechokwadi chekuti capacitor inoshanda pasi peiyo yakatemerwa voltage kwenguva yakareba, pasina kushandura overvoltage uye kuwedzera matambudziko aripo, ayo anowedzera zvakanyanya hupenyu hwebasa re capacitor;
e.Chishandiso chine dhigirii yakakwira yeautomation, mabasa ekudzivirira akazara, kutaurirana kwedhijitari uye mabasa ekuchengetedza kure, uye anogona kusangana nezvinodiwa zvekusatariswa uye kuchengetedza-pasina;
f.Iyo yekuwedzera kurasikirwa idiki, chete 2% ye capacitor kugona.Inenge chikamu chimwe chegumi chekurasikirwa kweSVC;
9. Macapacitors haafaniri kuchinjwa mumapoka, izvo zvinoderedza midziyo yakadai sekushandura kushandura uye kuvhara nzvimbo, uye kuchengetedza mari yekudyara kwezvivako;
h.Chigadzirwa chacho hachigadziri ma harmonics uye hachizokonzeri kusvibiswa kweharmonic kune system;
i.Kana paine nhevedzano reactor, iyo reactance rate yegiya rega rega inogona kuvimbiswa kuve yakagara;
