Zvinokonzera uye zvigadziriso zvegridi-yakabatana kabati kutsika kwe photovoltaic power station

Sezvo kudiwa kwepasi rose kwesimba rinowanikwazve kuri kuramba kuchikura, photovoltaic simba rekugadzira sechikamu chakakosha chesimba rakachena, kushandiswa kwayo kunowedzera uye kwakawedzera. Iyo grid-yakabatana maitiro eiyo photovoltaic magetsi chiteshi uye gidhi remagetsi ndiyo kiyi yekuona kushandiswa kwakanaka kweiyo photovoltaic simba rekugadzira system, pakati peiyo basa re "photovoltaic grid-yakabatana cabinet" yakakosha. Zvisinei, mukushanda kwegrid-yakabatana kushanda kwe photovoltaic power station, dambudziko re photovoltaic grid-yakabatana kabhineti tripping inowanzoitika.

Kutanga, iyo yakakosha zvikamu zve photovoltaic grid-yakabatana cabinet inosanganisira:
Inverter: Inoshandura yakananga ikozvino kuita inochinjisa ikozvino inosangana nefrequency uye voltage zvinodiwa pagridi.
Mudziyo wekudzivirira: kusanganisira overcurrent, overvoltage, frequency protection, grounding protection, etc., inogona kugura kuwirirana nemagetsi emagetsi kana girasi remagetsi risina kukwana, kudzivirira kukanganisa kune photovoltaic equipment.
Monitoring system: chaiyo-nguva yekutarisisa yemagetsi grid voltage, yazvino, frequency uye mamwe ma parameter kuti ave nechokwadi chekushanda kwakajairika kwehurongwa.

Chechipiri, zvikonzero zvinowanzoitika zve photovoltaic grid-yakabatana kabati kutsika
Pv grid-yakabatana kabati kutsika kunowanzo kukonzerwa nekukanganisa kwakasiyana kwemagetsi kana system abnormalities. Zvikonzero zvakananga zvinosanganisira zvinotevera zvinhu:

Kudzivirirwa kwakanyanya: Kana pfupi pfupi, kuremerwa kana zvimwe zvikanganiso zvemagetsi zvikaitika mugetsi remagetsi, ikozvino inogona kudarika zvakanyanya kushanda kwakajairika, zvichikonzera kukonzeresa kweiyo overcurrent kudzivirira mudziyo weiyo photovoltaic grid-yakabatana cabinet. Izvi ndezvekudzivirira mafungu akakwira kubva mukukuvadza kumidziyo, kunyanya yakakosha michina yakaita semainverters. Kana kukanganisa kwepamusoro kuchiitika, iyo grid-yakabatana cabinet inowanzobvisa pakarepo photovoltaic power station kubva kune grid.

Overvoltage kana undervoltage: Voltage fluctuations mugridi ndechimwe chikonzero chinowanzoitika chekugumburwa. Iyo yakavakirwa-mukati overvoltage uye undervoltage yekudzivirira mudziyo wePV grid-yakabatana kabati inogona kutarisa shanduko yemagetsi yegridi munguva chaiyo. Kana magetsi achinge adarika chikumbaridzo chakaiswa, iyo PV grid-yakabatana kabati inokonzeresa dziviriro yerwendo kudzivirira kukuvadzwa kwemidziyo kunokonzerwa nemagetsi akakwira, kana kusakwanisa kupa simba rakagadzikana kubuda kana voltage yanyanya kuderera.

Abnormal frequency: Kusajairika frequency yegedhi remagetsi (senge frequency inodarika iyo inotenderwa huwandu hwe50Hz kana 60Hz) inotungamira mukukuvadzwa kweiyo synchronous yegidhi remagetsi uye iyo photovoltaic chiteshi chemagetsi, uye wozoita kuti inverter isashande zvakajairika. Kana iyo gidhi yemagetsi frequency inotsauka kubva kune yakajairika renji, iyo frequency yekudzivirira mudziyo weiyo photovoltaic grid-yakabatana kabati ichatanga uye kudzima kubva kune yemagetsi grid kuti irege kukanganisa iyo photovoltaic midziyo.

Inverter kukundikana: Iyo inverter ndeimwe yezvikamu zvakakosha zveiyo photovoltaic chiteshi chemagetsi, uye kukundikana kwayo (sekupisa kwakanyanya, kuwandisa, kutadza kwehardware, nezvimwewo) chimwe chezvikonzero zvakakosha zverwendo rwegridhi-yakabatana kabati. Kana iyo inverter isingakwanisi kushandura DC ku AC, ikozvino haisati yasangana nezvinodiwa zvemagetsi emagetsi, zvichikonzera nzira yekudzivirira yegridhi-yakabatana cabinet.

Ground kukundikana: Kana iyo yepasi system ye photovoltaic power station ikakundikana, inogona kukonzera kuvuza ikozvino. Iyo grid-yakabatana cabinet inowanzove yakashongedzerwa nebasa rekudzivirira ivhu, uye kana kudonha kana kukanganisa kwepasi kwaonekwa, inozodzima kubatana pakati peiyo photovoltaic chiteshi chemagetsi uye grid kuti ive nechokwadi chekuchengetedzwa kwemagetsi.

Grid quality matambudziko: Kuchinja-chinja kwemhando yegridi, senge kusvibiswa kweharmonic, kuchinja kwemagetsi kana kugara uchichinja-chinja, zvinogona kukonzera kuti PV grid-yakabatana kabhineti ifambe. Kunyange zvazvo makambani egridhi anowanzo chengetedza hutano hwegridhi yakagadzikana, mune dzimwe nzvimbo, kana grid ichichinja zvikuru, photovoltaic magetsi emagetsi anogona kukanganisa.

Chechitatu, gadzirisa iyo photovoltaic grid-yakabatana kabhineti kutsika dambudziko
Kuti uderedze chiitiko che photovoltaic grid-yakabatana kabati kutsika uye kuona yakagadzikana grid-yakabatana photovoltaic chiteshi chemagetsi uye gidhi remagetsi, zvinokurudzirwa kutora matanho anotevera:

Kugara uchiyedza uye kugadzirisa: Nguva dzose kuchengetedza uye kuongororwa kwe photovoltaic grid-yakabatana makabati, kusanganisira kuongororwa kwakazara kwe inverters, zvigadziridzo zvekudzivirira ikozvino, zvigadziro zvepasi, etc. Nenzira iyi, zvinetso zvinogona kuonekwa panguva yakakodzera uye njodzi yekukundikana kwemichina inogona kuderedzwa.

Optimization yegridi-yakabatana Settings: Mune grid-yakabatana maitiro e photovoltaic magetsi zviteshi, iyo parameter yekumisikidza ye inverter yakakosha. Ita shuwa kuti inobuda voltage uye kuwanda kweiyo inverter inowiriraniswa neiyo gidhi remagetsi, uye nenguva gadzirisa maparamita ekugadzira magetsi eiyo photovoltaic chiteshi chemagetsi zvinoenderana nekushanduka kwegedhi remagetsi kudzivirira kudonha kunokonzerwa nevoltage kana frequency kusagadzikana.

Kushandiswa kwemidziyo yemhando yepamusoro: Kushandiswa kwepamusoro-soro photovoltaic inverters, grid-yakabatana makabati nemimwe michina yemagetsi inobatsira kuvandudza kugadzikana uye kuvimbika kwegadziriro. Kusarudza michina ine yakakwira kukanganisa kushivirira uye kufunga nezve shanduko mumhando yegridi mudhizaini inogona kuderedza zvakanyanya njodzi yekugumburwa.

Simbisa kusarudzwa kwenzvimbo dzekuwana grid: Kusarudzwa kwenzvimbo dzekuwana kune photovoltaic magetsi zviteshi zvinofanirwa kufunga nezvekuremerwa kwegidhi, kugadzikana uye kugona kwekutumira kwegridi. Kunyanya munzvimbo iyo girasi remagetsi rinonyanya kugadzikana, kuwirirana nekambani yemagetsi yekushanda kwemagetsi kunofanira kusimbiswa kuti ive nechokwadi chokuti mamiriro emagetsi ezvikamu zvakafanana zvinosangana nezvinodiwa.

Simbisa kudzidziswa kwevashandi vehunyanzvi: kudzidziswa kwehunyanzvi kwekushanda nekuchengetedza vashandi vezviteshi zvemagetsi ephotovoltaic kuti vaone kuti vanobata basa rekushanda uye nzira dzechimbichimbi dzekurapa kwemagetsi emagetsi ephotovoltaic, ayo anogona kudzivirira kudonha kwegedhi-akabatana makabati nekuda kwekusashanda zvakanaka.
