3.Txoj kev hloov pauv
Thaum lub converter yog powered mus rau hauv thawj zaug kaw, lub kaw lus tswj yuav ua kom tiav ib tug self-check xyuas qhov tseeb ntawm kev tswj thiab sensor systems.Lub vijtsam kov thiab DSP pib ib txwm thiab lub converter nkag mus rau lub xeev kaw.Thaum lub sij hawm kaw, lub zog cia converter thaiv lub IGBT pulses thiab disconnects AC / DC contactors.Thaum nyob rau hauv standby, lub zog cia converter thaiv lub IGBT pulses tab sis kaw lub AC / DC contactors thiab lub converter nyob rau hauv kub standby.
● Kaw
Lub zog cia converter nyob rau hauv hom kaw thaum tsis muaj cov lus txib lossis teem sijhawm tau txais.
Hauv hom kaw, lub converter tau txais cov lus txib ua haujlwm los ntawm lub vijtsam kov lossis lub khoos phis tawj sab saud thiab hloov ntawm hom kaw mus rau hom kev ua haujlwm thaum lub sijhawm ua haujlwm tau ua tiav.Hauv kev ua haujlwm hom, lub converter mus los ntawm kev ua haujlwm hom mus rau hom kaw yog tias tau txais cov lus txib kaw.
● Standby
Nyob rau hauv standby los yog kev khiav hauj lwm hom, lub converter tau txais ib tug standby hais kom ua los ntawm lub kov screen los yog lub computer sab sauv thiab nkag mus rau standby hom.Hauv hom standby, AC thiab DC contactor ntawm lub converter kaw, lub converter nkag mus rau hom kev khiav hauj lwm yog hais kom ua haujlwm lossis teem sijhawm tau txais.
● Khiav
Kev ua haujlwm hom tuaj yeem muab faib ua ob hom kev ua haujlwm: (1) off-grid operation mode thiab (2) grid-connected operation mode.Daim phiaj-txuas hom tuaj yeem siv los ua kom them thiab tso tawm.Nyob rau hauv daim phiaj-kev sib txuas hom, lub converter muaj peev xwm ua tau zoo zog tswj thiab reactive hwj chim tswj.Hauv hom off-grid, lub converter tuaj yeem muab qhov ruaj khov voltage thiab zaus tso tawm rau lub nra.
● Ua txhaum
Thaum lub tshuab ua haujlwm tsis zoo lossis cov xwm txheej sab nraud tsis nyob hauv lub tshuab ua haujlwm tau tso cai, lub converter yuav tsum tsis ua haujlwm;disconnect lub AC thiab DC contactors tam sim ntawd kom lub ntsiab Circuit Court ntawm lub tshuab yog disconnected ntawm lub roj teeb, daim phiaj los yog load, nyob rau hauv lub point nws nkag mus rau hauv lub xeev txhaum.Lub tshuab nkag mus rau hauv lub xeev txhaum thaum lub hwj chim tau raug tshem tawm thiab qhov txhaum tau raug tshem tawm.
3.Kev ua haujlwm hom
Cov kev ua haujlwm ntawm lub converter tuaj yeem muab faib ua ob hom kev ua haujlwm: (1) off-grid operation mode thiab (2) grid-connected operation mode.
• hom kab sib txuas
Hauv hom kab sib txuas, lub converter tuaj yeem ua haujlwm them thiab tso tawm.
Kev them nqi suav nrog kev them nyiaj tam sim no tsis tu ncua (DC), qhov hluav taws xob tsis tu ncua (DC), kev them hluav taws xob tas li (DC), lub zog them tsis tu ncua (AC), thiab lwm yam.
Kev tshem tawm suav nrog kev tawm tam sim no tsis tu ncua (DC), tsis tu ncua qhov hluav taws xob tawm (DC), lub zog tsis tu ncua (DC), tsis tu ncua lub zog tawm (AC), thiab lwm yam.
• Off-grid hom
Hauv hom off-grid, cov roj teeb raug tso tawm kom muab qhov hluav taws xob tas li thiab zaus AC lub zog hluav taws xob ntsuas ntawm 250kVA rau lub nra.Hauv microgrid systems, cov roj teeb tuaj yeem raug them yog tias lub zog tsim los ntawm lub tshuab hluav taws xob sab nraud ntau dua li lub zog siv los ntawm kev thauj khoom.
• Hloov hom
Hauv hom kab sib txuas, kev hloov pauv ntawm kev them nyiaj thiab tso tawm ntawm lub zog cia hloov pauv tuaj yeem nqa ncaj qha, tsis tas yuav nkag mus rau lub xeev standby.
Hloov ntawm kev them nyiaj thiab tawm hom thiab kev ywj pheej inverter hom tsis tuaj yeem ua tau nyob rau hauv lub xub ntiag ntawm daim phiaj.Nco tseg: Tsuas yog seamless switching hom.
Yuav tsum tsis muaj kab sib chaws rau qhov kev ywj pheej inverter ua haujlwm.Nco tseg: Tsuas yog kev ua haujlwm sib luag.
