Iyo grid-yakabatana inverter inoita sei kuyerera kwazvino mugedhi?

Mainverters akakosha kwazvo mumasisitimu emagetsi emazuva ano, kunyanya mumasisitimu emagetsi anovandudzwa. Basa guru re inverter ndere kushandura yakananga ikozvino inogadzirwa ne DC simba sosi yakadai se photovoltaic panel, fuel cell, kana lithium battery kune alternating current inopindirana negrid uye kuibatanidza kune grid.Maitiro ekuona kuyerera kwemazuva ano kupinda mugridi rave dambudziko iro vanhu vakawanda vari kunetseka pamusoro peiyi nzira.Musiyano unogona kuitika, mutsauko unogona kuve wakasiyana, uye nheyo yekushanda yegridi yemoto inotsanangurwa uye inotsanangurwa zviri nani kuti ipindure giradhi iyi-inverta ichatsanangurwa zviri nani kuti ipindure iyi grid. inverters, masero emafuta, kana lithium mabhatiri, pamwe chete neazvino kudzora basa reiyo inverter.

1. Ndeipi nzira iyo grid-yakabatana inverter inowana kuyerera ikozvino kune grid?

Iyo grid-yakabatana inverter basa rakakosha rinosanganisira kushandura DC kuita AC uye kuve nechokwadi chekuti inobuda AC inogona kudyirwa zvakanaka kupinda grid.Voltage matching uye frequency synchronization ndiyo misimboti yekushanda yeinverter.Iyo AC voltage inogadzirwa neinverter inoda kuenderana maererano neamplitude, frequency, uye phase ine gridver voltages mupati yemagetsi. ipapo haigoni kunyorovesa kuyerera kwezvino mugridi uye inogona kutokanganisa kugadzikana kweiyo yekupedzisira.

Kuyerera kwezvino kunotevera musimboti wemusiyano ungangoitika: chete kana paine musiyano wevoltage pakati pemapoinzi maviri ndipo panogona kuyerera ikozvino kubva panzvimbo iyo voltage yakakwira kuenda kunzvimbo ine ikozvino yakaderera.Nemamwe mazwi, kune grid-yakabatana inverters, zvinoreva inobuda AC voltage yeinverter inoda kuchengetedza imwe mutsauko ungangoita kubva kune grid voltage. Kana iyo grid voltage yakakwira kupfuura inobuda voltage yeiyo inverter, yazvino haizoyerere ichipinda mugidhi, uye inverter inoda kugadzirisa yakabuda voltage kuti ive nechokwadi chekuti yazvino inogona kuyerera mugidhi zvakanaka.

Uyezve, inofanirwa kutarisa nguva yakawanda uye chikamu chegridhi munguva chaiyo-nguva kuti ive nechokwadi chekuenderana.Irizvino yegridi uye ikozvino kubuda kweiyo inverter inofanira kuchengetedza nguva imwechete uye chikamu, kuitira kuti kana ikozvino inopinda mukati megridhi, haizokonzeri chero mutsauko wechikamu chinoguma nekushanduka kwegridi. Naizvozvo, iyo inverter inova nechokwadi chekuti inobuda AC inogona kuyerera zvakatsiga kupinda mugidhi nekudzora voltage, frequency, uye chikamu.

2.Is inogona here kana kuti inogona kusiyana inodiwa kuti igadzire kuyerera kwezvino mugedhi?
Hongu, kuyerera kwemagetsi kunonyanya kufambiswa nemusiyano ungangoita kana musiyano unogona. Musiyano ungangove mutsauko pakati pezviviri zvinogoneka, uye musiyano wevoltage unoreva musiyano wevoltage pakati pemapoinzi maviri. Mukushandiswa kwegridhi-yakabatana inverter, mutsauko wevoltage pakati peiyo inverter uye gidhi inosarudza gwara rekuyerera kwazvino. Izvo chete kana pane imwe mutsauko unogona kuitika pakati pekubuda kwemagetsi e inverter uye grid voltage, ikozvino inoyerera ichienda kune grid.Inverter inovimbisa kuti iyi kusiyana kwemagetsi iri mukati mehutano hwakakodzera kuburikidza nekugadzirisa mhepo inobuda kuti isangane nechinangwa chayo chekubvumira kuyerera ikozvino kune grid.

3.Kuti iyo photovoltaic grid-yakabatana inverter inogona kubatana nemafuta sero kana lithium bhatiri inofungidzirwa pano pazasi kuti ione giredhi yemagetsi:
Photovoltaic grid-yakabatana inverters inogona kubatanidzwa kwete chete kune photovoltaic panel system asiwo kune mamwe marudzi emagetsi emagetsi eDDC, semafuta emagetsi kana mabheteri e-lithium, nokuda kwegridhi-yakabatana kugadzirwa kwemagetsi.Nheyo yekutanga yekushanda yakafanana: yakananga ikozvino inoshandurwa kuita alternating ikozvino inopindirana negridi kuburikidza ne inverter.

Izvo zvinobuda maitiro emafuta emafuta uye mabhatiri e-lithium akafanana neaya e photovoltaic masero: zvose zvinopa simba reDC, asi simba ravo uye ikozvino kubuda kunogona kunge kwakasiyana.Kazhinji, simba rekubuda kwesero remafuta rinokanganiswa zvakanyanya nekuchinja kwemutoro, uye simba reti lithiamu bhatiri rinogona kuchinja nemamiriro ekutengesa uye hutano hwehutano hwebheteri. Naizvozvo, kana aya masisitimu emagetsi achipindirana negridi, inverter inoda kuchinjika zvakakwana mukugadzirisa voltage uye yazvino kubuda kuitira kuti inyatso kuenderana nevoltage, frequency, uye chikamu chegridi.

Kazhinji kutaura, photovoltaic grid-yakabatana inverters inogona kubatanidzwa kune grid nemafuta cell uye lithium bhatiri masisitimu, chero iyo inverter inogona kunyatso shandura yakananga ikozvino kubva kune akasiyana masosi emagetsi kuita alternating ikozvino yakakodzera grid uye inogona kutarisana nematambudziko ekuchinja kwebhatiri kana mafuta cell kubuda.

4.Kana grid-yakabatana kugadzirwa kwemagetsi kunoitwa, iyo inverter inogona kudzikamisa ikozvino here?
Ikozvino kudzikamisa ibasa rakakosha regridhi-yakabatana inverter, kunyanya mukuita kwemagetsi ekugadzira magetsi.Iyo inverter inogona kutarisisa ikozvino uye voltage mutoro wegridi uye inokwanisa kudzikamisa ikozvino nekugadzirisa simba rekubuda.Kana bhatiri rave kubhadhariswa zvakanyanya kana simba regedhi rekutakura rakakura, iyo inverter inogadzirisa otomatiki zvinobuda kuti irege kuwedzeredza ikozvino kupinda mugedhi remagetsi kudzivirira kuwandisa kwegedhi mudziyo wemagetsi.

Basa rekugadzirisa remazuva ano, rakapiwa mu inverter, rinoritungamirira mukati ne algorithm nenzira iyo iyo yakabuda ikozvino haipfuuri iyo inobvumirwa negridi.Somuenzaniso, kana kuchinja kwemagetsi kana kuchinja kwemutoro kunoitika mukati megridi, inverter inoderedza kamwe chete simba rinobuda kuti rirege kuchinja kusingakoshi ikozvino uye kuchengetedza grid kugadzikana.

Mune mamwe mazwi, iyo yazvino inomisa basa reiyo inverter inova nechokwadi chekuti chengetedzo uye kugadzikana kunochengetwa mugidhi remagetsi uye inodzivirira yakawandisa magetsi grid mutoro kana kukuvara kwemidziyo inogona kukonzerwa nekuwanda kwekubuda kweiyo inverter.

Iyo grid-yakabatana inverter inoshanda nekugadzirisa inobuda voltage, frequency, uye chikamu kuti ivimbise kuti inowiriraniswa neiyo grid voltage, nekudaro ichigonesa kuyerera kweazvino kupinda mugridi. Zvinoenderana nemusiyano ungangoitika kana musiyano wevoltage, uye ndipo ipapo iyo yazvino ichayerera zvakanaka kupinda mugridi; ndiko kuti kana musiyano wakakodzera wevoltage uripo pakati pe inverter inobuda voltage uye grid voltage. panel asiwo magetsi emagetsi eDC akadai semafuta emafuta uye lithiamu mabhatiri.Naizvozvo, inverter inofanira kuchinjwa zvakakwana kuti igadzirise kushanduka kubva kune zvakasiyana-siyana zvemagetsi.Pakupedzisira, ikozvino inogadzirisa basa re inverter inogona kunyatsodzivirira iyo grid mutoro kubva pakukura zvakanyanya, uye iva nechokwadi chekuchengetedzwa uye kugadzikana kwemagetsi emagetsi akabatanidzwa.
