Kodi Maximum Power Point Tracking mu Solar Water Pump Inverter Ndi Chiyani?

Mphamvu yapamwamba yowunikira MPPT imatanthawuza kuti inverter imasintha mphamvu yotulutsa mphamvu ya photovoltaic array malinga ndi maonekedwe a kutentha kozungulira ndi kuwala kwakukulu, kotero kuti gulu la photovoltaic nthawi zonse limatulutsa mphamvu zambiri.

Kodi MPPT imachita chiyani?

Chifukwa cha chikoka cha zinthu zakunja monga kuwala kwamphamvu ndi chilengedwe, mphamvu yotulutsa mphamvu ya maselo a dzuwa imasinthidwa, ndipo magetsi opangidwa ndi kuwala kwamphamvu ndi ochulukirapo.The inverter ndi MPPT pazipita mphamvu kutsatira ndi kugwiritsa ntchito mokwanira ma cell a dzuwa kuwapangitsa kuthamanga pa pazipita mphamvu mfundo.Ndiko kunena kuti, pansi pa chikhalidwe cha kuwala kwa dzuwa kosalekeza, mphamvu yotulutsa mphamvu pambuyo pa MPPT idzakhala yapamwamba kuposa ya MPPT, yomwe ndi udindo wa MPPT.

Mwachitsanzo, taganizirani kuti MPPT sinayambe kutsatira, pamene mphamvu yamagetsi ya chigawocho ndi 500V.Kenako, MPPT ikayamba kutsatira, imayamba kusintha kukana kwa dera kudzera m'dera lamkati kuti lisinthe mphamvu yamagetsi yagawo ndikusintha zomwe zikuchitika mpaka mphamvu yotulutsa ikupitilira (tiyeni tinene kuti ndi 550V pazipita), ndipo ndiye imapitiriza kutsatira.Mwanjira iyi, ndiko kunena kuti, pansi pa chikhalidwe cha kuwala kwa dzuwa kosalekeza, mphamvu yotulutsa chigawo pa 550V yotulutsa magetsi idzakhala yapamwamba kuposa ya 500V, yomwe ndi udindo wa MPPT.
Kawirikawiri, mphamvu ya kuwala ndi kusintha kwa kutentha pa mphamvu yotulutsa mphamvu ikuwonekera kwambiri mu MPPT, ndiko kuti, kuwala ndi kutentha ndizofunikira kwambiri zomwe zimakhudza MPPT.

Ndi kuchepa kwa kuwala, mphamvu yotulutsa ma modules a photovoltaic idzachepetsedwa.Ndi kuwonjezeka kwa kutentha, mphamvu yotulutsa ma modules a photovoltaic idzachepa.

Inverter maximum power point tracking (MPPT) ndikupeza malo apamwamba kwambiri amphamvu pachithunzi pamwambapa.Monga tikuwonera pachithunzi pamwambapa, mphamvu yayikulu kwambiri imachepa pafupifupi molingana ndi kuwala komwe kumachepa.

Ndi chitukuko chaukadaulo wamagetsi, kuwongolera kwaposachedwa kwa MPPT kwama solar arrays nthawi zambiri kumatsirizidwa ndi DC/DC conversion circuit.Chithunzi chojambula chikuwonetsedwa pansipa.

Ma cell a photovoltaic ndi katundu amalumikizidwa kudzera mu dera la DC / DC.Chipangizo chapamwamba kwambiri cholondolera mphamvu nthawi zonse chimazindikira kusintha kwamakono ndi magetsi a photovoltaic array, ndikusintha PWM kuyendetsa chizindikiro cha ntchito ya DC / DC converter malinga ndi kusintha.

Pampu yamadzi ya solarinverteropangidwa ndi kupangidwa ndi Xi 'an Noker Electric amagwiritsa ntchito ukadaulo wa MPPT, amagwiritsa ntchito bwino gulu la solar, aligorivimu wotsogola, ntchito yokhazikika komanso yodalirika, ndi chinthu cholimbikitsidwa kwambiri.
