Zida

A: Pochita zinthu ziwirizi zikuphatikizana, ndipo malirewo amaikidwa ndi mphamvu ndi kuwongolera. Mphamvu ya 500/630 kW ndi yopanda thiransifomamphamvu kutembenuka dongosolo: imagwiritsa ntchito kusintha kwa batri ya DC kupita ku AC yokha, ilibe PV MPPT, imayendetsa mphamvu-yamagetsi osasintha-ndipo imadalira EMS yakunja pa RS485 kapena TCP/IP. Chigawo cha 160 kW chimatchedwa inverter yosungirako mphamvu chifukwa chimathandiza kuti-pawoke ntchito, VSG grid-kupanga mphamvu ndi ma frequency-machitidwe oyankha monga FFR, FCR ndi FCAS. Pamwamba pa 500 kW msika pafupifupi nthawi zonse umagwiritsa ntchito mawu akuti PCS.

A: Kukula kuchokera ku mphamvu yotulutsa. Dongosolo la 1 MWh lotulutsa maola awiri likufunika pafupifupi 500 kW ya kutembenuka, kotero imodzi 500 kW PCS ikukwanira; maola anayi, pafupifupi 250 kW. Kenako yang'anani mphamvu ya DC: 500/630 kW PCS imalandira 600-900 V, kotero chingwe cha batri chiyenera kukhazikitsidwa mkati mwa zeneralo. Ngati batire imamangidwa pa 1500 V, gwiritsani ntchito inverter ya 160 kW m'magulu ofanana m'malo mwake, kapena onjezani gawo la DC / DC.

A: Inde. Zinthu ziwiri ziyenera kukumana: kuchuluka kwa batire ya DC iyenera kugwera mkati mwa zenera losinthira, ndipo BMS iyenera kulumikizana ndi RS485 kapena CAN. The 160 kW inverter amalankhulanso Modbus TCP/RTU ndi CAN 2.0, ndi 30 kW bidirectional inverter akuwonjezera Efaneti ndi WiFi. The 30 kW unit imavomereza lithiamu, lead{{8}acid, sodium-ion ndi kusunga flywheel. Tumizani chikalata choyankhulirana cha BMS ndi kafukufukuyo ndipo mapu ake afufuzidwa dongosolo lisanatsimikizidwe.

A: The microgrid hybrid inverter, chifukwa MPPT imapangidwira. Imavomereza 250-1000 V PV kulowetsa pa 1 mpaka 10 trackers kutengera chitsanzo, ndipo mphamvu yaikulu ya PV imaposa mlingo wa AC - 500 kW unit imatenga mpaka 825 kW ya modules. Kuchulukitsitsa kumeneko ndikwachilendo kwa DC-mapangidwe ophatikizana, chifukwa mndandandawu sufika potulutsa dzina. Pa retrofit pomwe PV ili kale inverter yake, gwiritsani ntchito PCS kapena 160 kW inverter pa basi ya AC m'malo mwake.

A: The PCS ndi microgrid wosakanizidwa inverter onse kusunga 110% mosalekeza ndi 120% kwa mphindi imodzi. Inverter ya 160 kW imanyamula 176 kVA yaitali-pa 1.1× ndi 1.5× kwa masekondi khumi. 30 kW bidirectional inverter ili ndi mapindikidwe opindika: 110–120% kwa mphindi khumi, 120–130% kwa mphindi imodzi, 130–150% kwa 200 ms ndi pamwamba pa 150% kwa 100 ms — yothandiza pamene injini yoyambira magetsi iyenera kutsekedwa-

A: Inverter ya 160 kW yokha, yovoteledwa ndi IP66 yokhala ndi −25 digiri mpaka +60 digiri renji ndi kuyika kwa lathyathyathya, ofukula kapena kukhoma{4}}kuyika pakhoma. PCS ndi IP21 ndipo inverter ya microgrid hybrid ndi 30 kW bidirectional inverter ndi IP20 - onse atatu amafunikira chipinda chamkati, chidebe kapena kabati yakunja.

A: Inverter ya microgrid hybrid imaphatikiza kusintha kosinthira ndi kapitao wokonza, motero imazimitsa-gridi popanda zida zowonjezera, imanyamula katundu wosakwanira 100% ndikuwongolera kuchuluka kwa kuchuluka kwa jenereta ya dizilo kudzera pamalo owuma. The 160 kW inverter ili ndi stand{4}mode yokhazikika yokhala ndi VSG control, kotero imapanga grid m'malo motsatira. The 30 kW bidirectional inverter imagwira ntchito-gridi yokhala ndi mayunitsi ofikira khumi mosalekeza-control parallel ndipo imatenga switch switch yanzeru kuti isungire zosunga zobwezeretsera. 500/630 kW PCS ndi grid-yomangidwa ndi LVRT ndi HVRT ndipo siinagwiritsidwe ntchito{13}paokha.

A: Zimatengera msika komwe mukupita. PCS imanyamula EN 50549-1 ya EU, GB/T 34120 ndi GB/T 34133 ya China ndi PTPiREE Rev 1.2:2024 Type B ya Poland. The 30 kW bidirectional inverter ndi yovomerezeka ku UL 1741 SA, IEEE 1547, Rule 21 ndi UL 9540A yaku North America. Inverter ya microgrid hybrid imakhala ndi NRS 097-2-1:2024 ya South Africa ndi ASGC yaku Australia. Inverter ya 160 kW imaphimba onse EN 50549 ndi UL 1741 ndi IEEE 1547.

A: Mtundu wa cell. Mndandanda wa 700 W umagwiritsa ntchito 210 mm theka-maselo mu 2384 × 1303 mm chimango pa 38 kg, ndi mphamvu kuchokera 22.54% kufika 23.18%. Module ya 630 W imagwiritsa ntchito ma 182 mm theka-maselo mu furemu yaing'ono ya 2382 × 1134 mm pa 33 kg, ndipo imafika pamlingo wapamwamba wa 23.32%. Paneni yokulirapo imagwirizana ndi-zokwera ndi zofunikira-zosanjikizana momwe ma module amafunikira; 630 W ndiyosavuta kugwira padenga lanyumba komanso mkati mwa zotengera zoyendera dzuwa.

A: Dongosolo lochepera ndi gawo limodzi la otembenuza ndi phale limodzi la ma module. Zitsanzo zimatumizidwa m'masiku 7-15 ogwira ntchito ndi maoda a voliyumu m'masiku 25-35 ogwira ntchito atasungitsa. Nameplate ndi ma CD zitha kusinthidwa kuchokera ku mayunitsi 10; mtundu wamkati ndi chilankhulo cha HMI kuchokera ku mayunitsi 50. Nthawi yotsogolera imatsimikiziridwa ndi satifiketi yofunikira, popeza-kuvomereza kwa gridi kungathe kuwonjezera nthawi.
