Pamberi pekusimuka kweiyo photovoltaic indasitiri, inverter kana inverter tekinoroji yainyanya kushandiswa kumaindasitiri akadai senjanji yekufambisa uye magetsi. Mushure mekusimuka kweiyo photovoltaic indasitiri, iyo photovoltaic inverter yakave iyo yakakosha midziyo mune itsva simba rekugadzira simba system, uye inozivikanwa kune wese munhu. Kunyanya munyika dzakabudirira muEurope neUnited States, nekuda kwechirevo chakakurumbira chekuchengetedza simba uye kuchengetedza kwezvakatipoteredza, misika ye photovoltaic yakagadzirwa kare, kunyanya kukurumidza kukura kwemhuri photovoltaic systems. Munyika dzakawanda, inverters yemumba yakashandiswa semidziyo yemumba, uye mwero wekupinda wakakwira.
Iyo photovoltaic inverter inoshandura yakananga ikozvino inogadzirwa ne photovoltaic modules mune inochinjanisa ikozvino uye inoidyisa mugridi. Kuita uye kuvimbika kweiyo inverter inosarudza kunaka kwesimba uye simba rekugadzira simba rekugadzira magetsi. Nokudaro, iyo photovoltaic inverter iri pakati peiyo yose photovoltaic simba rekugadzira system. chimiro.
Pakati pavo, grid-yakabatana inverters inotora chikamu chikuru chemusika mumapoka ese, uye zvakare iri kutanga kwekuvandudzwa kwese inverter tekinoroji. Kuenzaniswa nemamwe marudzi e inverters, grid-yakabatana inverters iri nyore mune tekinoroji, inotarisa pane photovoltaic yekupinda uye grid kubuda. Yakachengeteka, yakavimbika, inoshanda, uye yepamusoro-mhando yekuburitsa simba rave rekutarisa kweakadaro inverters. technical zviratidzo. Mumamiriro ehunyanzvi egridi-yakabatana photovoltaic inverters akaumbwa munyika dzakasiyana, mapoinzi ari pamusoro akave akajairwa kuyerwa mapoinzi eiyo chiyero, hongu, iwo mameseji ematanho akasiyana. Kune grid-yakabatana inverters, zvese zvinodiwa zvehunyanzvi zvakanangana nekusangana nezvinodiwa zvegidhi kune akagoverwa chizvarwa masisitimu, uye zvimwe zvinodikanwa zvinobva kune izvo zvinodikanwa zvegidhi kune inverters, ndiko kuti, kumusoro-pasi zvinodiwa. Zvakadai semagetsi, frequency yakatarwa, simba remhando zvinodiwa, chengetedzo, kutonga zvinodiwa kana kukanganisa kukaitika. Uye kuti ungabatanidza sei kune grid, chii chinonzi voltage level power grid kuti iise, nezvimwewo, saka grid-yakabatana inverter nguva dzose inoda kusangana nezvinodiwa zvegridhi, hazvibvi kune zvinodiwa mukati memagetsi ekugadzira simba. Uye kubva pakuona kwehunyanzvi, chinhu chinonyanya kukosha ndechekuti grid-yakabatana inverter "grid-yakabatana simba rekugadzira", ndiko kuti, inoburitsa simba kana ikasangana negridhi-yakabatana mamiriro. mune simba rekutonga nyaya mukati me photovoltaic system, saka zviri nyore. Zviri nyore semuenzaniso webhizinesi wemagetsi ayo anogadzira. Maererano nehuwandu hwekune dzimwe nyika, kupfuura 90% ye photovoltaic systems dzakavakwa uye dzakashandiswa ndeye photovoltaic grid-yakabatana zvirongwa, uye grid-yakabatana inverters inoshandiswa.
Kirasi ye inverters yakatarisana negridi-yakabatana inverters iri off-grid inverters. Iyo off-grid inverter inoreva kuti kubuda kweiyo inverter hakuna kubatana kune grid, asi yakabatana nemutoro, iyo inotyaira zvakananga mutoro kupa simba. Kune mashoma mashandisirwo e-off-grid inverters, kunyanya mune dzimwe nzvimbo dziri kure, uko grid-yakabatana mamiriro haawanikwe, iyo grid-yakabatana mamiriro yakashata, kana pane kudikanwa kwekuzvigadzira uye kuzvishandisa, iyo off. -grid system inosimbisa "self-generation uye kuzvishandisa". ". Nekuda kwekushandiswa kushoma kwe-off-grid inverters, pane tsvakiridzo uye budiriro muhunyanzvi tekinoroji. Kune mashoma epasi rose zviyero zvehunyanzvi mamiriro e-off-grid inverters, izvo zvinotungamira kushoma uye kushoma tsvakiridzo nekuvandudzwa kwemainverters akadaro, kuratidza maitiro ekuderera Zvisinei, mabasa e-off-grid inverters uye teknolojia inobatanidzwa haisi nyore, kunyanya mukubatana nemabhatiri ekuchengetedza simba, kutonga uye kutonga kwehurongwa hwose hwakaoma kupfuura. grid-yakabatana inverters Inofanira kutaurwa kuti iyo inoumbwa ne-off-grid inverters, photovoltaic panels, mabhatiri, mitoro nemimwe michina yatova nyore micro-grid system .
Saizvozvo,off-grid invertersndiwo hwaro hwekuvandudzwa kwebidirectional inverters. Bidirectional inverters inonyatso batanidza hunyanzvi hunhu hwegridi-yakabatana inverters uye off-grid inverters, uye anoshandiswa mumagetsi emunharaunda magetsi kana masisitimu ekugadzira magetsi. Kana ichishandiswa mukufambirana negetsi remagetsi. Kunyangwe hazvo pasina akawanda mashandisirwo erudzi urwu parizvino, nekuti iyi mhando yehurongwa ndiyo prototype yekuvandudzwa kwemicrogrid, inoenderana nehurongwa hwekuvaka uye hwekutengesa mashandiro emagetsi akagoverwa mune ramangwana. uye ramangwana renzvimbo microgrid application. Zvechokwadi, mune dzimwe nyika uye misika umo photovoltaics iri kukura nokukurumidza uye yakakura, kushandiswa kwema microgrids mudzimba uye nzvimbo duku kwakatanga kukura zvishoma nezvishoma. Panguva imwecheteyo, hurumende yemunharaunda inokurudzira kuvandudzwa kwekugadzirwa kwemagetsi emunharaunda, kuchengetedza uye kushandiswa kwemagetsi nedzimba sezvikamu, zvichipa zvakakosha kune simba idzva rekugadzira simba rekuzvishandisa, uye chikamu chisina kukwana kubva kune grid magetsi. Naizvozvo, iyo bidirectional inverter inoda kufunga nezve mamwe mabasa ekutonga uye masimba ekutonga simba, senge bhatiri kuchaja uye kuburitsa kudzora, grid-yakabatana / off-grid maitiro ekushanda, uye mutoro-akavimbika emagetsi ekupa. Zvese mune zvese, iyo bidirectional inverter ichatamba yakanyanya kukosha kutonga uye manejimendi mabasa kubva pakuona kwehurongwa hwese, pane kungofunga zvinodikanwa zvegidhi kana mutoro.
Seimwe yenzira dzekusimudzira gidhi remagetsi, kugadzirwa kwemagetsi emunharaunda, kugovera uye kushandiswa kwemagetsi network yakavakwa nemagetsi matsva ekugadzira simba sezvo musimboti uchave imwe yenzira huru dzekusimudzira microgrid mune ramangwana. Mumamiriro ezvinhu aya, iyo microgrid yemunharaunda ichaumba hukama hunopindirana negridhi yakakura, uye microgrid haichazoshanda padhuze pane grid hombe, asi ichashanda zvakanyanya yakazvimirira, ndiko kuti, mune chitsuwa mode. Kuti usangane nekuchengetedzeka kwedunhu uye kupa pamberi peakavimbika simba rekushandisa, iyo grid-yakabatana maitiro ekushanda inoumbwa chete kana simba renzvimbo rakawanda kana richida kudhonzwa kubva kunze kwegetsi remagetsi. Parizvino, nekuda kwemamiriro ekusakura eakasiyana matekinoroji uye marongero, mamicrogrid haana kushandiswa pamwero mukuru, uye vashoma chete mapurojekiti ekuratidzira ari kushanda, uye mazhinji emapurojekiti aya akabatanidzwa kune grid. Iyo microgrid inverter inosanganisa tekinoroji maficha eiyo bidirectional inverter uye inotamba yakakosha grid manejimendi basa. Iyo yakajairika yakabatanidzwa kutonga uye inverter yakabatanidzwa muchina unobatanidza inverter, kutonga uye manejimendi. Inotora simba remunharaunda manejimendi, kudzora mutoro, kutonga kwebhatiri, inverter, kuchengetedza uye mamwe mabasa. Ichapedzisa basa rekutungamirira re microgrid yose pamwe chete ne microgrid energy management system (MGEMS), uye ichava midziyo inokosha yekuvaka microgrid system. Kuenzaniswa neyekutanga grid-yakabatana inverter mukuvandudza inverter tekinoroji, yakaparadzana kubva kune yakachena inverter basa uye yakatakura basa reiyo microgrid manejimendi uye kutonga, kuterera uye kugadzirisa mamwe matambudziko kubva padanho rehurongwa. Iyo inverter yekuchengetedza simba inopa bidirectional inversion, ikozvino shanduko, uye bhatiri kuchaja uye kuburitsa. Iyo microgrid manejimendi system inobata iyo yose microgrid. Contactors A, B, uye C ese anodzorwa neiyo microgrid manejimendi system uye anogona kushanda muzvitsuwa zviri kure. Gurai mitoro isingakoshi maererano nemagetsi nguva nenguva kuchengetedza kugadzikana kweiyo microgrid uye kushanda kwakachengeteka kwemitoro yakakosha.
