Sisitimu Yekudzora Mashandiro Akafanana
Tsananguro yeChigadzirwa
Kutanga, ndeapi mamiriro ezvinhu ekushanda kwakafanana kwemaseti ejenareta?
Maitiro ese ekuisa seti yejenareta mukushanda kwakafanana anonzi parallel operation. Seti yekutanga yejenareta ichashanda, voltage inotumirwa kubhazi, uye imwe seti yejenareta mushure mekutanga, uye seti yekare yejenareta, inofanira kunge iri panguva yekuvharwa, seti yejenareta haifanirwe kuoneka seyakanyanya kukuvadza, shaft haikanganisike kamwe kamwe. Mushure mekuvhara, rotor inofanira kudhonzwa nekukurumidza kuti ienderane. (ndiko kuti, kumhanya kwerotor kwakaenzana nekumhanya kwakayerwa) Saka, seti yejenareta inofanira kusangana nemamiriro anotevera:
1. Kukosha kunoshanda uye chimiro chemafungu emagetsi ejenareta zvinofanira kunge zvakafanana.
2. Chikamu chemagetsi chemagetsi maviri aya chakafanana.
3. Kuwanda kwemaseti maviri ejenareta kwakafanana.
4. Kutevedzana kwezvikamu zvemaseti maviri ejenareta kunoenderana.
Chechipiri, ndeipi nzira ye quasi-synchronous juxtaposition yemaseti ejenareta? Maitiro ekugadzira juxtapositions panguva imwe chete?
Quasi-synchronous ndiyo nguva chaiyo. Nekushandisa nzira yequasi-synchronous yekushanda kwakafanana, voltage yejenareta inofanira kunge yakafanana, frequency yakafanana uye phase inoenderana, iyo inogona kutariswa nemavoltmeter maviri, mamita maviri efrequency uye zviratidzo zvesynchronous nenon-synchronous zvakaiswa padhisiki resynchronous, uye matanho ekushanda kwakafanana ndeaya anotevera:
Chinobatidza load switch cheimwe generator set chinovharwa, uye voltage inotumirwa kubhawa rebhazi, nepo imwe unit iri mumamiriro ekumira.
Vhara kutanga kwenguva imwe chete, gadzirisa kumhanya kweseti yejenareta yakamira, kuitira kuti ienzane kana kuti ive pedyo nekumhanya kwe synchronous (musiyano we frequency neimwe unit mukati mehafu ye cycle), gadzirisa voltage ye seti yejenareta yakamira, kuitira kuti ive pedyo ne voltage ye seti yejenareta imwe, kana frequency ne voltage zvakafanana, kumhanya kwekutenderera kwetafura ye synchronous kunononoka uye kunononoka, uye chiedza che indicator chinopenyawo uye chine rima panguva imwe chete; Kana phase ye unit inofanira kusanganiswa yakafanana neyeimwe unit, synchronous meter pointer inoratidza nzvimbo yepakati yepamusoro, uye synchronous rambi iri shoma. Kana musiyano we phase pakati pe unit inofanira kusanganiswa neimwe unit wakakura, synchronous meter inonongedzera panzvimbo yepakati iri pasi, uye synchronous rambi iri kubatidzwa panguva ino. Kana synchronous meter pointer ichitenderera ne clockwise, zvinoratidza kuti frequency ye synchronous generator yakakwira kupfuura yeimwe unit. Kumhanya kwe seti ye jenareta yakamira kunofanira kuderedzwa, uye kumhanya kwe seti ye jenareta yakamira kunofanira kuwedzerwa kana clock pointer yatenderedzwa ne counterclockwise. Kana pointer yewachi ikatenderera zvishoma nezvishoma munzira yewachi uye pointer ichisvika panzvimbo imwe chete, circuit breaker yeyuniti inofanira kusanganiswa inovharwa ipapo ipapo, kuitira kuti majenareta maviri aya aenderane. Maswichi echronograph akabviswa padivi nepadivi uye machronoswitch anoenderana nawo.
Chechitatu, chii chinofanira kutariswa pakuita quasi-synchronous juxtaposition yejenareta set?
Quasi-synchronous parallel ibasa rinoitwa nemaoko, kunyangwe basa racho rakanyatsonaka uye ruzivo rwemushandisi rwune hukama hwakanaka, kuitira kudzivirira ma parallel akasiyana e synchronous, nyaya nhatu dzinotevera hadzibvumirwi kuvhara.
1. Kana pointer yetafura yekubatana ikaonekwa sechiitiko chekusvetuka, haibvumirwi kuvhara, nekuti panogona kunge paine chiitiko chekaseti mukati metafura yekubatana, chisingaratidze mamiriro akakodzera ekubatana.
2. Kana tafura yesynchronous ichitenderera nekukurumidza, zvinoratidza kuti musiyano wefrequency pakati peseti yejenareta neimwe seti yejenareta wakakura zvakanyanya, nekuti nguva yekuvharira yeseti yecircuit breaker yakaoma kuinzwisisa, kazhinji circuit breaker haivharwe panguva imwe chete, saka haibvumirwi kuvhara panguva ino.
3. Kana wachi ikamira panguva imwe chete, haibvumirwi kuvhara. Izvi zvinodaro nekuti kana frequency yeimwe jenareta ikachinja kamwe kamwe panguva yekuvhara, zvinokwanisika kuita kuti circuit breaker ivhare panzvimbo isina kuenderana.
Chechina, nzira yekugadzirisa simba rekudzokera shure remayuniti akafanana?
Kana majenareta maviri asina chinhu, pachava nemusiyano wefrequency nemusiyano wevoltage pakati pemaseti maviri. Uye pachishandiso chekutarisa chemayuniti maviri (ammeter, power meter, power factor meter), mamiriro chaiwo esimba reinverse anoratidzwa, rimwe isimba reinverse rinokonzerwa nekumhanya kusingaenderane (frequency), rimwe isimba reinverse rinokonzerwa nevoltage isina kuenzana, iyo inogadziriswa seinotevera:
