Yini i-Reverse Power Protection of Generator set

Njengomnikazi nomsebenzisi wesethi yejeneretha, umsebenzisi kufanele aqonde zonke izici zesethi yejeneretha, ukuze akwazi ukusebenza futhi asebenzise izindlela zesethi yejeneretha.Namuhla inkampani ye-Dingbo Power yabelana ngokuvikelwa kwamandla okuhlehla kwesethi yejeneretha.

Ukuvikelwa kwamandla okuhlanekezela isethi ye-generator kubizwa nangokuthi ukuvikelwa kwesiqondiso samandla.Ngokuvamile, isiqondiso samandla ejeneretha kufanele sisuke kujeneretha siye ebhasini.Kodwa-ke, lapho i-generator ilahlekelwa injabulo noma ngenxa yesinye isizathu, i-generator ingase ishintshe ekusebenzeni kwemoto, okungukuthi, idonsa amandla asebenzayo ohlelweni, okungamandla ahlehlayo.Uma amandla ahlehlayo efinyelela inani elithile, ukuvikelwa kwejeneretha kuyasebenza, noma kwenza umsebenzi wokusayinda noma uhambo.

Ukusebenza okuhambisanayo kwamasethi amabili ejeneretha kadizili kuzohlangabezana nemibandela yesigaba esifanayo se-voltage yokuphehla ugesi, imvamisa efanayo ijeneretha kagesi kanye nokulandelana kwesigaba esifanayo sesethi yejeneretha.Ekusetshenzisweni kwangempela, lapho amasethi amabili ejeneretha kadizili ehambisana ngaphandle komthwalo, kuzoba nenkinga yomehluko wemvamisa kanye nomehluko kagesi.Kwesinye isikhathi amandla wangempela ahlehlayo azotholwa nethuluzi lokuqapha, okungamandla ahlehlayo abangelwa i-voltage engalingani.Omunye umsebenzi wokuhlehla obangelwa isivinini esingahambisani (imvamisa).Ngokubhekana nalesi simo, ukulungiswa okuhambisanayo kufanele kwenziwe.

1.Ukulungiswa kwamandla ahlehlayo okubangelwa umehluko kagesi.

Lapho inkomba yemitha yamandla yawo womabili amasethi akhiqizayo inguziro futhi i-ammeter isenenkomba yamanje, inkinobho yokulungiswa kagesi yesethi eyodwa yejeneretha kadizili ingalungiswa ngokuya ngenkomba ye-ammeter kanye nesici samandla.

2.Ukulungiswa kwamandla ahlehlayo okubangelwa imvamisa.

Uma ama-frequency amayunithi amabili ehlukile futhi umehluko mkhulu, i-current unit enesivinini esikhulu ibonisa inani elihle futhi imitha yamandla ibonisa amandla amahle.Ngokuphambene nalokho, okwamanje kubonisa inani elibi futhi amandla abonisa inani elibi.

Ngalesi sikhathi, lungisa isivinini sesethi yejeneretha yedizili futhi ulungise inkomba yemitha yamandla ibe ziro.Kodwa-ke, lapho i-ammeter isenayo inkomba, lena isenzakalo samandla ahlehlayo esibangelwa umehluko we-voltage.

Ezimweni eziningi, ukuxhumana okuhambisanayo kwamasethi ejeneretha yedizili ngeke kukhiqize amandla ahlehlayo.Amajeneretha ambalwa kuphela ane-voltage ephansi yokuphumayo ngenxa yokulawula okungalungile lapho exhunywe kugridi.Kudingeka sihlaziye izimbangela ngokushesha futhi sithathe izinyathelo ezifanele zokulungisa.

Yini umsebenzi wokuvikela amandla ahlehla ejeneretha?

Lapho amasethi ejeneretha kadizili angaphezu kwamabili esebenza ngokuhambisana, uma injini yedizili yesethi eyodwa yejeneretha yedizili ingasebenzi ngendlela evamile noma ipharalleli phakathi kwenjini yedizili kanye nejeneretha yonakalisiwe, i-generator yeyunithi ayikwazi ukukhipha amandla asebenzayo, kodwa imunce. amandla avela ohlelweni lokuphakelwa kwamandla, futhi i-generator synchronous iba injini ehambisanayo, okungukuthi, i-generator synchronous isebenza ngamandla abuyela emuva.

Uma ijeneretha ehambisanayo isebenza esimweni samandla ahlehlayo, ayilungile kusistimu yokuphakela amandla, okuholela ekukhubekeni kokugcwala kwamanye amayunithi abamba iqhaza ukusebenza okuhambisanayo kanye nokuphazamiseka kokuphakelwa kukagesi.Ngakho-ke, kuzothathwa izinyathelo zokuvikela amandla okuhlehla.

Singasebenzisa idivayisi yokuvikela amandla okuhlanekezela i-transistor.

Njengoba isivikelo samandla ahlehlayo siyisivikelo sesiqondiso samandla asebenzayo, isignali yayo yokutholwa kufanele ithathe amasignali we-voltage kanye neyamanje kanye nobudlelwano bawo besigaba, futhi iyiguqule ibe isignali yokulawula kagesi ye-DC ebonisa isiqondiso nosayizi wamandla asebenzayo.

Isiginali yokuvikela amandla ehlehlayo yedivayisi ithathwa kuvoltheji kanye namanje wesigaba sika-S sejeneretha ukuze kutholwe amandla ahlehlayo kwesigaba esisodwa.Kumjikelezo wayo wokwakha amandla kagesi, izinhlangothi eziyinhloko zeziguquli zamandla kagesi i-M1 ne-M2 zixhunywe ezinkanyezini ezilinganayo, futhi i-voltage Uso′ ikhishwa njengesignali kagesi.Futhi wenze i-Uso' ibe yisigaba nge-voltage yesigaba ye-USO ephuma yijeneretha.Isignali yayo yamanje itholwa yi-S-phase transformer yamanje futhi yalungiswa ngamasekethe amabili okulungisa ibhuloho lesigaba esisodwa VD1 kanye ne-VD2.Ku-voltage U1 ye-resistor R3, i-voltage U2 ye-resistor R4 kanye nesixhumanisi sokuthola amandla, isimiso sokuqhathanisa inani eliphelele sizosetshenziselwa ukutholwa.Uma i-R1 = R2, i-DC yokulawula isignali ye-voltage yesignali ye-UNM ngesixhumanisi sokutholwa kwamandla ilingana ngokuqondile namandla asebenzayo P futhi ibonisa isiqondiso sika-P. Ngamandla ahlehlayo, i-DC yokulawula isiginali ye-voltage ye-UNM ayilungile, okungukuthi, i-N -amandla ephuzu angaphezulu kwe-m-point.Uma amandla ahlehlayo efinyelela ku-8% wamandla alinganiselwe ejeneretha, i-triode VT1 ivuliwe futhi i-VT2 ivaliwe.Ugesi osebenzayo ushaja i-capacitor C ngama-resistors u-R15 no-R16, nokubambezeleka kokushaja okungama-5s.Lapho i-voltage yokushaja ye-capacitor C ifinyelela ku-voltage yokuwohloka ye-voltage stabilizing tube W1, i-tube W1 ivuliwe, i-diode VD3 ne-triode VT3 iyavulwa, i-outlet relay D1 ivuliwe futhi isebenza, futhi ukushintshwa kwamandla kagesi kuhamba ngokuzenzakalelayo, ukuze kuzuzwe inhloso yokuvikela.
