Indasitiri application yeMCR mhando ine simba reactive simba rekubhadhara mudziyo

MCR mhando dynamic reactive simba rekubhadhara mudziyo unogona kushandiswa zvakanyanya mundima dzinotevera.

1 Simba System

1) Kazhinji substation. Nekuwedzera MCR ine humwe huwandu pahwaro hwekutanga capacitor bhangi, iyo ine simba uye inoenderera kudzora kwesimba rinoita muchiteshi chinoitwa, chiitiko chinowanzoitwa chevanopwanya chedunhu chinodziviswa, chiyero chekushandiswa kwema capacitor chinovandudzwa zvakanyanya, uye iyo simba factor inovandudzwa zvakanyanya.

2) Hub substation. Nekuisa chigadziriso chemagetsi chemuripo chinoumbwa nemcr + fc sefa muhub substation, kana kuwedzera MCR pahwaro hwefirita yekutanga yeFC kuti igadzire chigadziriso chesimba rekubhadhara simba, kuvandudza kugadzikana kwegidhi remagetsi uye kuwedzera simba rekutapurirana. mutsara.

3) Low voltage reactor. Kuchinja-low-voltage reactor ye substation muMCR kwete chete ine mabasa ose e-low-voltage reactor, asiwo ine basa rekugadzirisa simba rekugadzirisa simba.

4) Mutsetse reactive simba muripo. Kuburikidza nechiyero chakakodzera checapacitor kugona uye MCR chiyero, kuita kwevacuum contactor kunogona kudzivirirwa, kuvimbika uye kuchengetedzeka kwemidziyo kunogona kuvandudzwa, uye hupenyu hwesevhisi hwemidziyo hunogona kuwedzerwa zvakanyanya.

5) Reactive simba muripo wekugovera transformer. Tsc + mcr tekinoroji inogamuchirwa kuti ivandudze zvikuru kurongeka kwemuripo (0.2 kvar), kuderedza zvakanyanya kuchinja kwekuita frequency, uye nekuita shuwa kuti reactive simba muripo wekugovera shanduri inosvika kune yakakwirira simba chinhu che0 99-1, ziva iyo chaiyo inoshanda. simba configuration layered partition balance.

2 Metallurgical System

Rolling mill uye emagetsi arc furnaces ndiwo anonyanya kuita reactive impulse loads. Kushandisa mcr + fc sefa ye dynamic reactive simba muripo anogona kuvandudza simba chinhu, kuderedza voltage fluctuation uye flicker, kubvisa kusvibiswa kweharmonic, kunatsiridza simba remagetsi, kunatsiridza kuchengetedza kwesimba remagetsi system, kuderedza kushandiswa kwesimba pakugadzira kweyuniti, uye kugadzirisa chigadzirwa. quality.

3 Electrified Railway

Chitima chemagetsi chinotora imwe-phase magetsi ekupa maitiro. Nekuda kwekusarongeka kwelocomotive, kuremerwa kwettraction substation ine hunhu hweimwe-chikamu chekukanganisa mutoro, neanogara achichinja-chinja uye yakakwira harmonic yemukati. Izvo hazvigoneke kuona yakakwira simba chinhu muripo nekushandisa yakapusa yakagadziriswa muripo maitiro. Kana MCR ine simba rakakodzera yakaiswa pahwaro hweFC sefa yedunhu ine huwandu hwakakwana, yakakwira simba chinhu muripo unogona kuwanikwa chero nguva, voltage fluctuation inogona kuderedzwa uye voltage mhando inogona kuvandudzwa.

Hunhu hwechikamu chimwe-chikamu chekutakura njanji ine magetsi inounzawo matambudziko akakomba epamusoro asina kunaka kutevedzana chikamu kune yayo yepamusoro magetsi substation, uye inototungamira kune yakaipa kutevedzana kudzivirira chiito chemagetsi emagetsi uye substations. Nekuisa mcr + fc mafirita muzviteshi izvi uye nekutora zano rekuparadzanisa chikamu chekutonga zvinoenderana nenzira yeSteinmetz, dambudziko iri rinogona kugadziriswa nemazvo, uye rinogona kubatanidzwa zvakananga kune 110 kV magetsi system yekuripa, pasina kuisirwa mari. vashanduri vepakati, nzvimbo yepasi idiki, uye kurasikirwa kwemidziyo pachayo kunogona kuderedzwa neinopfuura 70%.
