Cov txheej txheem kev sib txuas ib txwm cia siab rau phau ntawv sib dhos, uas yog siv sijhawm ntev thiab ua haujlwm hnyav, thiab qib ntawm automation qis, thiab kev xaiv ntawm lub sijhawm sib dhos muaj kev sib raug zoo nrog kev ua haujlwm ntawm cov neeg ua haujlwm sib luag. Muaj ntau ntau yam ntawm tib neeg, thiab nws yog ib qho yooj yim uas tshwm sim loj impulse tam sim no, uas ua rau kev puas tsuaj rau lub diesel generator teeb thiab shortens lub neej ntawm lub diesel generator teeb. Yog li ntawd, Cummins qhia txog lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab kev tsim hluav taws xob ntawm qhov tsis siv neeg synchronous parallel maub los ntawm diesel generator teeb. Lub synchronous parallel maub los muaj cov qauv yooj yim, kev ntseeg siab thiab siab engineering daim ntawv thov tus nqi.
Cov xwm txheej zoo tshaj plaws rau kev ua haujlwm sib luag ntawm lub tshuab hluav taws xob teeb tsa thiab cov phiaj xwm hluav taws xob lossis lub tshuab hluav taws xob yog tias plaub lub xeev cov xwm txheej ntawm cov khoom siv hluav taws xob ntawm ob sab ntawm cov kab hluav taws xob sib txuas, cov hluav taws xob sib txuas yog tib yam, uas yog, theem sib lawv liag. ntawm lub hwj chim mov ntawm ob sab ntawm lub parallel sab thiab lub system sab yog tib yam, qhov voltage yog sib npaug, zaus yog sib npaug, thiab theem sib txawv yog xoom.
Qhov muaj qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov sib txawv yuav ua rau muaj qee qhov kev sib pauv ntawm lub zog reactive thiab lub zog ua haujlwm ntawm ob sab ntawm daim phiaj kev sib txuas lub sijhawm thiab qhov sib txuas, thiab cov phiajcim lossis lub tshuab hluav taws xob yuav raug cuam tshuam rau qee yam. Nyob rau hauv sib piv, lub hav zoov ntawm theem sib txawv yuav ua rau kev puas tsuaj rau lub generator teeb, uas yuav ua rau sub-synchronous resonance thiab puas lub generator. Yog li ntawd, ib qho zoo tsis siv neeg synchronous palallel maub los yuav tsum xyuas kom meej tias theem sib txuas, cia ua kom tiav cov phiaj xwm kev sib txuas, cia cov kev sib txawv ntawm voltage thiab zaus sib txawv.
Lub synchro module txais cov analog Circuit Court tswj system, txais yuav classical PI tswj txoj kev xav, muaj qhov zoo ntawm cov qauv yooj yim, paub tab, kev ua haujlwm zoo thiab lwm yam. Lub hauv paus ntsiab lus ua haujlwm yog: Tom qab tau txais cov lus qhia synchronous input, lub tshuab synchronizer tsis siv neeg tshawb pom ob lub AC voltage teeb liab ntawm ob chav nyob ua ke (los yog ib daim phiaj thiab ib chav tsev), ua kom tiav cov theem sib piv thiab tsim kho cov teeb liab analog DC. Lub teeb liab yog ua tiav los ntawm PI arithmetic circuit thiab xa mus rau qhov kawg ntawm qhov kawg ntawm lub tshuab hluav taws xob ceev tswj ntawm lub cav, kom cov theem sib txawv ntawm ib chav tsev thiab lwm chav tsev (lossis daim phiaj hluav taws xob) ploj hauv lub sijhawm luv luv. Lub sij hawm no, tom qab lub synchronization nrhiav pom Circuit Court paub meej tias lub synchronization, cov zis kaw teeb liab ua tiav cov txheej txheem synchronization.
