PCS, okanye Power Conversion System, yibhulorho phakathiibhetri yokugcina amandlakunye negridi yamandla, engaqapheli kuphela ukuguqulwa phakathi kwe-DC kunye ne-AC amandla kodwa inika ulawulo lwamandla oluchanekileyo kunye nolawulo lwamandla ngokwemfuno yegridi yamandla kunye nemeko yebhetri. Kwimeko yenguqu yangoku yamandla, ukuphuhliswa kobugcisa bokugcina amandla kubaluleke kakhulu, kwaye i-PCS, njengenxalenye ephambili yenkqubo yokugcina amandla, idlala indima ebalulekileyo ekufezekiseni ukugcinwa ngokufanelekileyo kunye nokulawulwa kwamandla ombane.
Isebenza Njani Inkqubo Yokuguqula Amandla ePCS?
I-PCS ye-Power Conversion System iqulunqwe ngamandla ombane, iisistim zolawulo kunye nokubeka iliso kunye neebhetri. Umgaqo wayo kukuqonda ukuguqulwa okusebenzayo kunye nokuhamba ngeendlela ezimbini kwamandla ngokusebenzisa i-electronics yamandla ukuqinisekisa ukusebenza okuzinzileyo kunye nokusetyenziswa ngokufanelekileyo kwenkqubo yokugcina amandla. Xa igridi idinga inkqubo yokugcina amandla ukuze ikhuphe, i-PCS iguqula amandla e-DC kwibhetri yokugcina amandla kwi-AC kwaye ikhuphe kwigridi; xa igridi idinga inkqubo yokugcina amandla ukuze ihlawule, i-PCS iguqula amandla e-AC kwigridi kumandla e-DC kwaye iyigcine kwibhetri yokugcina.
Amacandelo kunye noBume beNkqubo yoGuqulo lwaMandla e-PCS

Iimeko zeSicelo seNkqubo yokuGuqulwa kwamandla ePCS
Ukuhlelwa kweemeko zesicelo se-PCS kunokufumaneka ku:Yintoni umahluko phakathi kwe-PCS yogcino olukhulu, ugcino lwentengiso kunye neshishini, kunye nokugcinwa kwendlu?
Iindlela ezi-3 zokuSebenza kweNkqubo yokuGuqulwa kwamandla e-PCS
I-Power Conversion System (PCS) isebenza kwezi ndlela zintathu zilandelayo: imowudi edityanisiweyo yegridi, i-off-grid okanye imo eyodwa, kunye ne-hybrid mode.
Imowudi eqhagamshelwe kwigridi/ Qonda indlela ezimbini zokuguqula amandla phakathi kwebhanki yebhetri kunye negridi yamandla
Kwimowudi edityanisiweyo yegridi, i-Energy storage system PCS iqonda ukuguqulwa kwamandla e-bi-directional phakathi kwesixhobo sokugcina kunye negridi ngokwemiyalelo yekhompyutha yokusingatha, kwaye ineempawu ze-inverter.
Indima ephambili:
Uthintelo lwesiphumo se-island: kumisa ngokuzenzekelayo unikezelo kwimeko yokusilela kwamandla egridi. Ukulungelelanisa ukusebenza kwegridi: landelela ngokuzenzekelayo kwaye ulungelelanise isigaba samandla ombane wegridi kunye nokuphindaphinda.
Ngokusebenzisa amandla ombane aphantsi: gcina ukusebenza ukumelana nokuncipha kwexesha elifutshane lomthombo wamandla ombane wegridi ukuqinisekisa uzinzo lwenkqubo yamandla.
Ngaphandle kwegridi okanye iMowudi yeSiqithi/ ukusebenza ngokuzimeleyo kunye nokunikezelwa kwamandla ukusuka kwigridi engundoqo
Kwi-off-grid okanye imo yodwa, i-PCS yokugcina inokusebenza ngokuzimeleyo kwigridi eyintloko ukubonelela ngemithwalo yendawo kunye namandla e-AC ahlangabezana neemfuno zekhwalithi zamandla egridi. Kwiindawo ezikude kunye neenkqubo zamandla ezigciniweyo ezingxamisekileyo, i-off-grid okanye imo ekwanti ibalulekile ekungafumanekiyo indawo yokuqinisekisa umbane.
Indima ephambili:
Ukunikezelwa kwamandla okuzimela: ukubonelela ngokuzimeleyo amandla ombane we-AC ngokweemfuno ezimiselweyo.
Unikezelo lwamandla kaxakeka: Ukutshintshela ngokukhawuleza kwi-off-grid okanye imo yegridi eyodwa ukuze umelane neemeko ezingalindelekanga.
Imowudi yeHybrid/ Ukutshintsha okuguquguqukayo phakathi kwemowudi eqhagamshelwe kwigridi kunye ne-off-grid
Imowudi yeHybrid ivumela inkqubo yokugcina ibhetri ukuba itshintshe phakathi kwegridi-eqhagamshelwe kunye ne-off-grid modes, iqinisekisa ukuthembeka kwenkqubo kunye nokuguquguquka ukuziqhelanisa neendawo ezinzima kunye nokutshintsha kwegridi.
Indima ephambili:
Ukusebenza kwe-Microgrid: Xa i-microgrid inqanyuliwe kwigridi kawonkewonke, inokutshintshwa ngokuguquguqukayo kwi-off-grid okanye imodi esecaleni ukuze ikhusele ukunikezelwa kwamandla ngokusebenzisa inkqubo yokugcina amandla kwi-microgrid.
Usetyenziso olunemisebenzi emininzi: inokuqonda ukuhluza, ukuzinzisa igridi yamandla kunye nokulawula umgangatho wamandla, iimpazamo zokuziphilisa, ukubuyisela kunye nokukhusela unikezelo lwamandla.
Iintsingiselo kwiNkqubo yoGuqulo lwaMandla ePCS
Ukusebenza okuphezulu, ulawulo olukrelekrele kunye nokudityaniswa okunzulu kweenkqubo zamandla ezininzi ziindlela ezizayo zePCS.
Uxinano lwaMandla aPhezulu kunye noKusetyenzwa okuPhezulu kwePCS zexesha elizayo ziya kusebenzisa izixhobo eziphucukileyo ze-semiconductor zamandla kunye nobuchwepheshe bokulahla ubushushu ukuphucula ukuxinana kwamandla kunye nokusebenza kakuhle koguqulo, kunye nokunciphisa iindleko zesixhobo kunye nomthamo. Ngelo xesha, ukusetyenziswa kwe-architecture ye-1500V ye-architecture kuya kwandisa ngakumbi ubuninzi bamandla kunye nokusebenza kakuhle kwenkqubo, kwaye ibe sisisombululo esiphambili sobugcisa ukunciphisa iindleko kunye nokwandisa ukusebenza kakuhle. Abavelisi ngabanye bacebise inkqubo yenkqubo ye-2000V.
I-PCS ekrelekrele kunye nedibeneyo iya kuthandeka ukuba nobukrelekrele, ixhotyiswe nge-algorithms yolawulo oluphezulu kunye ne-sensors ukufezekisa ukwenza izigqibo ezizimeleyo kunye nokusebenza kakuhle. Ukongezelela, i-PCS iya kuhlanganiswa kunye nezinye iinkqubo eziphambili (ezifana nebhetri yokugcina amandla, inkqubo yokulawula ibhetri ye-BMS, inkqubo yokulawula amandla i-EMS, njl.) ukuphucula ukuthembeka kwenkqubo kunye nokugcinwa.
Ukusetyenziswa kwamandla amaninzi kunye ne-microgrid ye-PCS iya kusetyenziswa ngeendlela ezininzi zamandla (ilanga, umoya, i-hydro, njl. njl.) ngendlela ehambelanayo ukuze kuphuhliswe uphuhliso lwamandla olwahlukeneyo noluzinzileyo. Kwii-microgrids, i-PCS iya kudlala indima ebalulekileyo ekuqinisekiseni ukusebenza okuzinzile kunye nokulawulwa ngokufanelekileyo kwee-microgrids ukuhlangabezana neemfuno ezithile zeemeko ezicandekileyo.
Inkqubo yokuguqulwa kwamandla (i-PCS) vs. I-Inverter yokuGcinwa kwamandla kunye ne-Booster Inverter?
Inkqubo yoGuqulo lwaMandla (PCS):
I-PCS sisixhobo esingundoqo kwinkqubo yokugcina amandla, esetyenziselwa ukuqonda ukuguqulwa kwamandla kunye nokuhamba kwe-bidirectional phakathi kwebhetri yokugcina kunye negridi yamandla. Isenokuba yi-DC/AC converter (inverter function) okanye i-AC/DC converter (umsebenzi wokulungisa).
Iqukethe i-DC / AC ye-bi-directional converter, iyunithi yokulawula, njl. Umlawuli ufumana umyalelo wolawulo lwangasemva ngonxibelelwano, kwaye ulawula umguquleli ukuba ahlawule okanye akhuphe ibhetri ngokwesimboli kunye nobukhulu bomyalelo wamandla, ukuqonda ukulawulwa kwamandla asebenzayo kunye asebenzayo kwigridi yamandla.
Iguqula i-alternating current (AC) yegridi yamandla ibe ngamandla eDC afunwa yibhetri, kwaye iguqula amandla eDC agcinwe ebhetrini abe ngamandla e-AC ukuze anikezelwe kwigridi yamandla.
Isiguquli sokuGcina amandla:
I-inverter yokugcina amandla igxile kakhulu kumsebenzi wokuguqula, okt ukuguqula amandla e-DC kumandla e-AC. Isetyenziswa ikakhulu ukuguqula amandla e-DC kwibhetri yokugcina amandla e-AC ukubonelela ngemithwalo ye-AC okanye ukuyidibanisa kwigridi yamandla e-AC.
Isiguquli se-Booster:
I-Booster Inverter sisixhobo esidityanisiweyo kakhulu esidibanisa i-converter yokugcina amandla (i-PCS) kunye ne-step-up transformer. Umsebenzi wokunyusa wongezwa ngesiseko sokuguqulwa kweendlela ezimbini zamandla kwi-PCS, ukwenzela ukuba amandla agciniweyo aguqulwe ngokufanelekileyo kwaye anyuswe ukuze ahlangabezane neemfuno zokufikelela kwigridi.
