IMP: Ekujwayezeni ukugqagqana okubili, futhi umngcele ubekwa ngamandla nobubanzi bokulawula. Iyunithi enamandla angu-500/630 kW iyi-transformerlessuhlelo lokuguqula amandla: iphatha ukuguqulwa kwebhethri ye-DC ukuya ku-AC kuphela, ayinayo i-PV MPPT, isebenzisa ukulawulwa kwamandla kagesi-okungashintshile noma okungashintshi{1}, futhi incike ku-EMS yangaphandle nge-RS485 noma i-TCP/IP. Iyunithi engu-160 kW ibizwa ngokuthi i-inverter yokugcina amandla ngoba yengeza -ukusebenza okukodwa, igridi ye-VSG-ukwenza imisebenzi yokulawula kanye nemvamisa{7}}njenge-FFR, i-FCR ne-FCAS. Ngaphezulu cishe ku-500 kW imakethe cishe njalo isebenzisa igama elithi PCS.

A: Usayizi kusuka emandleni okukhipha. Isistimu engu-1 MWh ekhipha amahora amabili idinga cishe u-500 kW wokuguqulwa, ngakho-ke i-PCS eyodwa engu-500 kW ilingana; amahora amane, cishe 250 kW. Bese uhlola amandla kagesi e-DC: i-500/630 kW PCS yamukela u-600–900 V, ngakho intambo yebhethri kufanele imiswe ngaphakathi kwalelo windi. Uma ibhethri lakhiwe ngo-1500 V, sebenzisa inverter engu-160 kW ngamaqembu ahambisanayo esikhundleni salokho, noma engeza isiteji se-DC/DC.

A: Yebo. Kufanele kuhlangatshezwane nemibandela emibili: ibhethri ye-DC voltage range kufanele iwele ngaphakathi kwefasitela lesiguquli, futhi i-BMS kufanele ixhumane nge-RS485 noma i-CAN. I-inverter engu-160 kW iphinde ikhulume i-Modbus TCP/RTU ne-CAN 2.0, kanti i-inverter engu-30 kW eqondiswa kabili yengeza i-Ethernet ne-WiFi. Iyunithi engu-30 kW yamukela i-lithium, i-lead-asidi, i-sodium-yokulondolozwa kwe-flywheel. Thumela idokhumenti yokuxhumana ye-BMS nombuzo futhi ukuhlelwa kwemephu kuyahlolwa ngaphambi kokuqinisekiswa kwe-oda.

A: I-microgrid hybrid inverter, ngoba i-MPPT yakhelwe ngaphakathi. Yamukela okokufaka okungu-250–1000 V PV kuwo wonke ama-tracker angu-1 ukuya kwangu-10 kuye ngemodeli, futhi amandla aphezulu e-PV edlula isilinganiso se-AC — iyunithi engu-500 kW ithatha kufika ku-825 kW wamamojula. Lokho kukhula ngokweqile kuvamile ku-DC{8}}imiklamo ehlanganisiwe, njengoba amalungu afanayo angavamile ukufinyelela okukhiphayo kwe-nameplate. Ukuze uthole i-retrofit lapho i-PV isivele ine-inverter yayo, sebenzisa i-PCS noma i-inverter engu-160 kW ebhasini le-AC esikhundleni salokho.

A: I-PCS kanye ne-microgrid hybrid inverter kokubili kusekela u-110% ngokuqhubekayo no-120% umzuzu owodwa. I-inverter engu-160 kW ithwala u-176 kVA{5}}isikhathi eside ku-1.1× kanye no-1.5× imizuzwana eyishumi. I-30 kW inverter ye-bidirectional bidirectional curve: 110–120% imizuzu eyishumi, 120–130% iminithi elilodwa, 130–150% engu-200 ms nangaphezulu kuka-150% ku-100 ms — iwusizo lapho uthuthuva oluqalayo kufanele luvaliwe{19}}

A: I-inverter engu-160 kW kuphela, elinganiselwe i-IP66 ngo-−25℃kuya ku- +60℃degree kanye nokufakwa okuyisicaba, okuqondile noma odongeni{4}}. I-PCS iyi-IP21 kanti i-microgrid hybrid inverter kanye ne-30 kW inverter ye-bidirectional yi-IP20 - bobathathu badinga igumbi elingaphakathi, isitsha noma ikhabethe elingaphandle.

IMP: I-microgrid hybrid inverter ihlanganisa ukudluliswa kweswishi kanye ne-bypass yokulungisa, ngakho iyacima-igridi ngaphandle kwezingxenyekazi zekhompuyutha ezengeziwe, isingatha u-100% womthwalo ongalinganiseli futhi ilawula izinga lokulayisha kwejeneretha kadizili ngothintwayo owomile. I-inverter engu-160 kW inemodi yokuma{4}}yodwa enolawulo lwe-VSG, ngakho yenza igridi kunokuyilandela. Isiguquli se-bidirectional esingu-30 kW sisebenza-kugridi enamayunithi angafika kwayishumi ngokudedelana{8}kukulawula okuhambisanayo futhi sithatha iswishi yokudlulisa ehlakaniphile yokuzikhethela ukuze wenze ikhophi yasenqolobaneni ngokuzenzekelayo. I-500/630 kW PCS iyiyunithi yegridi{12}}eboshiwe ene-LVRT ne-HVRT futhi ayihloselwe ukusebenza{13}}yodwa.

IMP: Kuncike emakethe yendawo. I-PCS iphethe i-EN 50549-1 ye-EU, i-GB/T 34120 kanye ne-GB/T 34133 yase-China kanye ne-PTPiREE Rev 1.2:2024 Uhlobo B lwase-Poland. I-30 kW inverter eqondiswa kabili iqinisekiswe ku-UL 1741 SA, IEEE 1547, Rule 21 kanye ne-UL 9540A yaseNyakatho Melika. I-inverter ye-microgrid hybrid ibamba i-NRS 097-2-1:2024 yaseNingizimu Afrika kanye ne-ASGC yase-Australia. I-inverter engu-160 kW ihlanganisa kokubili i-EN 50549 ne-UL 1741 nge-IEEE 1547.

A: Ifomethi yeseli. Uchungechunge lwe-700 W lisebenzisa amaseli angu-210 mm uhhafu-kufreyimu engu-2384 × 1303 mm ku-38 kg, ngokusebenza kahle kusuka ku-22.54% kuya ku-23.18%. Imojula engu-630 W isebenzisa amaseli angu-182 mm uhhafu{12}}kuhlaka oluncane lwe-2382 × 1134 mm ngo-33 kg, futhi ifinyelela ukusebenza kahle okuphezulu okungu-23.32%. Iphaneli elikhudlwana lifanelana{18}}nezindawo zesikali{19}}ezikhweziwe nezisetshenziswayo lapho kubalwa kwemojuli kubaluleke khona; i-630 W kulula ukuyiphatha ophahleni lwezentengiselwano nangaphakathi kweziqukathi zelanga.

A: I-oda elincane liyiyunithi eyodwa yeziguquli kanye nephalethi elilodwa lamamojula. Amasampuli athunyelwa ngezinsuku zokusebenza eziyi-7–15 nama-oda evolumu ezinsukwini zokusebenza ezingama-25-35 ngemuva kwediphozithi. I-Nameplate kanye nokupakishwa kungenziwa ngezifiso kusuka kumayunithi ayi-10; umbala obiyelwe nolimi lwe-HMI kusuka kumayunithi angama-50. Isikhathi sokuhola siqinisekiswa ngokumelene nesethi yesitifiketi esidingekayo, njengoba{9}}ukugunyazwa kwegridi ethile yezwe kunganweba ishejuli.
