Mawonekedwe

Kusinthasintha kwa gridi kwamphamvu:
Mphamvu yapamwamba komanso ma harmonics otsika;
Anti-islanding and islanding operation, support for high/low/zero voltage kukwera-kudutsa, kutumiza mphamvu mofulumira.
Kuwongolera kwathunthu kwa batri:
Bi-directional charge and discharge management of battery kuti atalikitse moyo wa batri.
Ndi ma aligorivimu a batri kuyitanitsa batri m'njira yabwino komanso yotetezeka;
Wide DC voltage yamitundu yosiyanasiyana ya mabatire.
Njira zingapo zogwirira ntchito, zokhala ndi pre-charge, kuyitanitsa nthawi zonse / voltage, kuyitanitsa mphamvu nthawi zonse ndi kutulutsa, kutulutsa nthawi zonse ndi zina.
Kutembenuza bwino kwambiri:
Ukadaulo wamagawo atatu a topology kuti atembenuke bwino mphamvu ndikusintha mpaka 97.5%;
1.1 nthawi yayitali yogwira ntchito mochulukira, yopereka chithandizo champhamvu cha gridi pamachitidwe onse molingana ndi kudalirika komanso kudalirika.
Kugwiritsa ntchito mphamvu zocheperako komanso kutayika kopanda katundu.
Chitetezo ndi kudalirika:
Chitetezo chokhazikika cha gridi, chowunikira zolakwika ndi ntchito zoteteza.
Kuyang'anira nthawi yeniyeni ya momwe ntchito ikugwirira ntchito komanso malo olakwika mwachangu.
Kugwirizana kwamphamvu:
Kuthandizira kutumiza ma grid angapo kuti apereke chipukuta misozi champhamvu komanso chokhazikika.
Thandizani mayunitsi angapo osinthira ofanana kulumikizana kuti mukwaniritse zofunikira zamphamvu kwambiri.
Ndi ntchito yolumikizidwa ndi gridi yolumikizidwa ndi gridi, yothandizira kusintha kwanzeru kwamagetsi olumikizidwa ndi gridi komanso osagwiritsa ntchito gridi.
Kukonza kutsogolo ndikuyika kosavuta, kusinthika kumasamba osiyanasiyana ogwiritsira ntchito.

Ntchito yaikulu
1) Ntchito yoyang'anira yoyambira
Kuwongolera kolumikizidwa ndi ma gridi kwa kulipiritsa ndi kutulutsa mphamvu kosalekeza;
Magetsi olumikizidwa ndi ma gridi ndi kuyitanitsa nthawi zonse;
Off-grid V/F control:
Ulamuliro wowongolera chipukuta misozi yamphamvu;
Pa-gridi / off-gridi yosalala yosinthira;
Anti-islanding chitetezo ntchito ndi kuzindikira pachilumba kwa kusintha mode;
Kuwongolera kolakwika;
2) Mafotokozedwe a ntchito yapadera ndi awa:
Kuthamangitsa batire yosungiramo mphamvu ndikuwongolera kutulutsa: Chosinthira chosungira mphamvu chimatha kulipiritsa ndikutulutsa batire.Mphamvu yolipiritsa ndi kutulutsa mphamvu ndizosankha.Mitundu yosiyanasiyana ya kuyitanitsa ndi kutulutsa malamulo amasinthidwa ndi chophimba chokhudza kapena kompyuta yolandila.
Njira zolipirira zimaphatikizapo kuyitanitsa nthawi zonse (DC), kuyitanitsa ma voliyumu pafupipafupi (DC), kuyitanitsa magetsi nthawi zonse (DC), kuyitanitsa magetsi osasintha (AC), ndi zina zambiri.
Njira zotulutsira zimaphatikizirapo nthawi zonse (DC), kutulutsa mphamvu pafupipafupi (DC), kutulutsa mphamvu pafupipafupi (DC), kutulutsa mphamvu kosalekeza (AC), ndi zina zambiri.
Kuwongolera mphamvu kwamphamvu: Zosintha zosungiramo mphamvu zimapereka chiwongolero cha mphamvu yamagetsi ndi chiwongolero champhamvu.Ulamuliro wa mphamvu yamagetsi ndi chiŵerengero cha mphamvu zogwira ntchito ziyenera kukwaniritsidwa mwa jekeseni mphamvu yogwira ntchito.
Ntchito yosinthira iyi imatha kuzindikirika mukamagwira ntchito zolipiritsa komanso zotulutsa.Kukhazikitsa kwamphamvu kwamphamvu kumachitidwa ndi kompyuta kapena skrini yogwira.
Magetsi otulutsa ndi kukhazikika kwafupipafupi: Zosintha zosungira mphamvu zimatha kusintha ma voliyumu otulutsa ndi kukhazikika pafupipafupi pamakina olumikizidwa ndi gridi powongolera mphamvu yogwira ntchito komanso mphamvu yogwira.Kuti mukwaniritse ntchitoyi, malo osungiramo mphamvu zazikulu amafunikira.
Kuwongolera kodziyimira pawokha kwa gridi yakutali: Chosinthira chosungira mphamvu chili ndi ntchito yodziyimira payokha mu gridi yakutali, yomwe imatha kukhazikika pamagetsi otulutsa ndi ma frequency ndikupereka mphamvu pazonyamula zosiyanasiyana.
Independent inverter parallel control: M'mapulogalamu okulirapo, ntchito yodziyimira payokha yodziyimira payokha yosinthira mphamvu yosungiramo mphamvu imawonjezera kubwereza komanso kudalirika kwadongosolo.Mayunitsi angapo osinthira amatha kulumikizidwa limodzi.
Zindikirani: Kulumikizana kodziyimira pawokha kwa inverter ndi ntchito yowonjezera.Chosinthira chosungira mphamvu chimasintha mosasunthika pakati pa grid-yolumikizidwa ndi inverter yodziyimira payokha, yomwe imafunikira chosinthira chakunja chakunja.
Chenjezo lolephera la zida zazikuluzikulu: Chenjezo loyambirira la momwe zimagwiritsidwira ntchito komanso kulephera kwa zida zazikulu zosinthira zosungira mphamvu kuti muwonjezere luntha lazinthu.

3.Kusintha mawonekedwe
Chosinthiracho chikatsegulidwa kuti chitsekedwe koyambirira, makina owongolera amamaliza kudzifufuza kuti atsimikizire kukhulupirika kwa machitidwe owongolera ndi masensa.Chojambula chojambula ndi DSP chimayamba bwino ndipo chosinthira chimalowa m'malo otseka.Panthawi yotseka, chosinthira chosungira mphamvu chimatchinga ma pulses a IGBT ndikudula ma AC/DC contactors.Ikakhala yoyimilira, chosinthira chosungira mphamvu chimatchinga ma pulses a IGBT koma amatseka ma AC / DC olumikizirana ndipo chosinthira chimakhala choyimirira.
● Tsekani
Chosinthira chosungira mphamvu chili munjira yotseka pomwe palibe malamulo ogwirira ntchito kapena ndondomeko yomwe idalandilidwa.
Mumayendedwe otsekera, chosinthira chimalandira lamulo la opareshoni kuchokera pazenera logwira kapena pakompyuta yapamwamba ndikusamutsa kuchokera kumachitidwe otsekera kupita kumachitidwe ogwirira ntchito zikakwaniritsidwa.Mumayendedwe opangira, chosinthiracho chimachoka pamachitidwe ogwirira ntchito kupita kumachitidwe otsekera ngati lamulo lotseka lalandiridwa.
● Kudikira
Mu standby kapena mode opareshoni, Converter amalandira lamulo standby kuchokera touch screen kapena pamwamba kompyuta ndi kulowa standby mode.Mu mode standby, ndi AC ndi DC contactor wa Converter kukhala chatsekedwa, Converter akulowa mumalowedwe ntchito ngati ntchito lamulo kapena ndandanda analandira.
● Kuthamanga
Njira zogwirira ntchito zitha kugawidwa m'njira ziwiri zogwirira ntchito: (1) off-grid operation mode ndi (2) njira yolumikizira gridi.Njira yolumikizidwa ndi gridi itha kugwiritsidwa ntchito kuyitanitsa ndi kutulutsa.Munjira yolumikizidwa ndi gridi, chosinthira chimatha kuwongolera mphamvu zamagetsi ndikuwongolera mphamvu zamagetsi.Munjira ya off-grid, chosinthiracho chimatha kupereka mphamvu yokhazikika komanso kutulutsa pafupipafupi pakunyamula.
● Zolakwa
Pamene makina akulephera kapena zochitika zakunja sizili mkati mwa makina ovomerezeka ogwiritsira ntchito, chosinthiracho chidzasiya kugwira ntchito;chotsani ma AC ndi DC olumikizana nawo nthawi yomweyo kuti dera lalikulu la makinawo lichotsedwe ku batire, gululi kapena katundu, pomwe limalowa m'malo olakwika.Makinawa amalowa m'malo olakwika pamene mphamvu yachotsedwa ndipo cholakwikacho chachotsedwa.
3.Operating mode
Njira zogwirira ntchito zosinthira zitha kugawidwa m'njira ziwiri: (1) mawonekedwe opangira ma gridi ndi (2) mawonekedwe ogwiritsira ntchito gridi.
• Njira yolumikizidwa ndi gridi
Munjira yolumikizidwa ndi gridi, chosinthira chimatha kugwira ntchito zolipiritsa ndi kutulutsa.
Kuchangitsa kumaphatikizapo kuyitanitsa nthawi zonse (DC), kuyitanitsa ma voliyumu pafupipafupi (DC), kuyitanitsa magetsi nthawi zonse (DC), kuyitanitsa magetsi nthawi zonse (AC), ndi zina zambiri.
Kutulutsa kumaphatikizapo kutulutsa nthawi zonse (DC), kutulutsa mphamvu pafupipafupi (DC), kutulutsa mphamvu kosalekeza (DC), kutulutsa mphamvu kosalekeza (AC), ndi zina zambiri.
• Off-gridi mode
Munjira ya off-grid, mabatire amatulutsidwa kuti apereke ma voliyumu osasintha komanso ma frequency amagetsi a AC ovoteledwa pa 250kVA pakunyamula.M'makina a microgrid, mabatire amatha kuimbidwa ngati mphamvu yopangidwa ndi jenereta yakunja ndi yayikulu kuposa mphamvu yomwe imagwiritsidwa ntchito ndi katundu.
• Kusintha kwa mawonekedwe
Munjira yolumikizidwa ndi gridi, kusinthana pakati pa kulipiritsa ndi kutulutsa kwa chosinthira chosungirako mphamvu kumatha kuchitidwa mwachindunji, popanda kufunikira kolowera.
Kusintha pakati pa kulipiritsa ndi kutulutsa mode ndi njira yodziyimira payokha sikutheka pamaso pa gridi.Zindikirani: Kupatula njira yosinthira yosasinthika.
Sipayenera kukhala kukhalapo kwa gridi kuti inverter yodziyimira igwire ntchito.Chidziwitso: Kupatula ntchito yofananira.
4.Basic chitetezo ntchito
Wotembenuza wanzeru ali ndi chitetezo champhamvu kwambiri, pomwe magetsi olowera kapena gridi amachitika, amatha kuchitapo kanthu kuti ateteze chitetezo cha otembenuza wanzeru mpaka zomwezo zitathetsedwa kenako ndikupitiliza kupanga magetsi.Zinthu zachitetezo zikuphatikizapo.
