Kugona kukonzeresa kuderedzwa (PID) kwatambudza indasitiri yezuva kubva payakabva.Chiitiko ichi chinoitika kana yakakwira-voltage DC yepurojekiti yezuva yakaiswa padyo nemimwe michina ine magetsi akasiyana.Kusiyana kunogona kukonzera kutama kwesodium, uko maerekitironi akavharirwa mumodule girazi kutiza uye nekumhanyisa kuparara kwemodule.
"Iyo hukuru hukuru hunofambisa iyi PID maitiro, kana ma modules kana magetsi emagetsi asina kugadzirwa neimwe nzira yekudzikisa izvi," akadaro Steven Marsh, mukuru mukuru wetekinoroji uye dhizaini mugadziri mukuru Origis Energy.
Mathin-film modules anotapukirwa nePID nekuda kweiyo yakakwira voltage uye kugadzira zvinhu, asi crystalline silicon mapaneru ari panjodzi. kana paine zvikanganiso muwafers.Developer Silicon Ranch inotungamira anti-PID mashandiro etambo inverters pamhando mbiri dzemapurojekiti.
"Vakagadzirwa zvakasiyana, asi zvakafanana pamusoro pepamusorogkunetseka kuti mugadziri wezuva anofanira kuve nazvo, zvinova izvi zvidiki kushaya simba munesolar panel, iwe unodzivirira neanopesana nePID maficha mune yakoinverters, "akadaro Nick de Vries, SVP wetekinoroji uye manejimendi emidziyo kuSilicon Ranch.
Kana tekinoroji nyowani yabuda, zvinowanzotora nguva kukwenenzvera chigadzirwa kuderedza njodzi yePID.Mhando dzekutanga dzegirazi-pa-girazi bifacial modules dzaive nenyaya nePID, asi vagadziri vakaita nhanho kubva ipapo, Marsh akadaro.
“[PID] inodzoka nguva nenguva sezvo tekinoroji inoshanduka, nekuda kwekuti itsva uye iri kusimukira.Chimiro chinoda zvikuru icho ma modules anofanira kupfuura, "akadaro.
Central inverters ibheti yakachengeteka yekudzivisa PID.Iwo anosanganisira akavakirwa-mukati matransformer ayo asina kudzika pasi, achitsaura iyo DC uye AC mativi ehurongwa.
Asi sezvo transformerless tambo inverters iri kuwedzera kuiswa pamapurojekiti akakura kune yavo O&M nyore, ine matete-firimu mapaneru uye neimwe nzira, varidzi veprojekiti vanofanirwa kufunga nezvePID kudzikiswa.
"Kune nzira shoma dzakakosha dzaungakwanise kuwana galvanic kuzviparadzanisa nevamwe, uye transformer ndiyo imwe yadzo.Kuita shanduko iyi kusaita shanduko zvinosiririsa zvinokonzeresa dambudziko iri, ”akadaro Marsh."PV array inozopedzisira yayangarara, uye kazhinji zvinoreva kuti ingangoita hafu yemamodule ari muhurongwa hwese vanosangana nerusaruro rusina kunaka pasi."
Nzira shoma dzinogona kushandiswa kubatsira kudzivirira PID mune transformerless tambo inverters.Vanoisa vanogona kuwedzera yakadzika yekuzviparadzanisa transformer kana pasi nhanho-kumusoro transformer padivi reAC.Uye vagadziri vava kuwedzera yakakosha hardware uye software kune tambo inverters kurwisa PID.
Marsh akati kune mapoka maviri ePID kuderedza mutamboinverters-Inoshanda inorwisa-PID nzira uye inongoita PID yekudzoreredza modhi.Active anti-PID hardware uye software mhinduro dzinotora iyo DC divi resisitimu uye kusimudza voltage kuitira kuti ma modules ave pamusoro pevhu.Kune rimwe divi, nzira dzekudzoreredza dzePID dzinoshanda husiku kuti dzigadzirise iyo PID yakaunganidzwa mukati mezuva.Nekudaro, mutete-mugadziri wefirimu First Solar anoti mamodules ayo anopindura zvakanyanya kune anoshanda anti-PID mashandiro pane PID kupora.
Vagadziri vashoma tambo inverter pamusika zvino vanosanganisira anti-PID hardware uye inoperekedza software yekudzivirira kubva mukuora, kana kutengesa zvakaparadzana zvishandiso kuita mabasa ekudzivirira.Semuenzaniso, CPS America inopa iyo CPS Energy Balancer, nepo Sungrow ichivaka anti-PID hardware mune yayo SG125HV uye SG250HX tambo inverters.Sungrow akatanga kupa anti-PID tambo inverters kutenderera 2018.
"Pakanga paine mibvunzo pamusoro pekuderedzwa kwemazinga epaneru panguva iyoyo, saka takagadzira mhinduro," akadaro Daniel Friberg, director wechigadzirwa uye engineering kuSungrow.
Yaskawa Solectria nguva pfupi yadarika yakazivisa anti-PID vhezheni yayo XGI 1500-250 yakatevedzana tambo inverter iyo yakagadzirirwa kushanda neFirst Solar thin-film modules.
"Izvo zvinotora shanduko shoma shoma mukati kune inverter.Haisi dhiri hombe, asi inoda imwe nguva yeinjiniya uye rondedzero yemhando yemhando nyowani mune ino nhevedzano, saka tiri pakati pekuratidza kuti kunze mulab, "akadaro Miles Russell, director wechigadzirwa. manejimendi kuYaskawa Solectria Solar.
Vese Solectria uye Yekutanga Solar vanogadzira zvigadzirwa zvavo muUnited States, vachipa vanoisa nyore pairing kuti vazadzikise zvemukati zvinokurudzira zvinangwa zvinosanganisirwa muIRA.Asi vakakurukura kuderedzwa kwePID zvakanaka isati yanyorwa IRA.
"Takatanga hukama uhwu makore maviri apfuura, tiine chinangwa chehunyanzvi hwekuwana chigadzirwa chinowirirana nechigadzirwa chedu," akadaro Alex Kamerer, maneja wepurojekiti paFirst Solar."Tinoenda rimwe danho rekuona kuti tinowirirana nevanovapa sisitimu, izvo zvinobatsira vatengi vedu."
Kunyangwe vagadziri vakawanda vanogadzira inverter vari kutanga kubatanidza anti-PID mabasa mutambo inverters sezvo tekinoroji iri kuwedzera kushandiswa mumapurojekiti akakura, mainjiniya dzimwe nguva anofanirwa kuchera kuburikidza nemapepa e data kuti atarise kugona kwechigadzirwa anti-PID, sekureva kwaOrigis's Marsh.
"Isu tinoona kuti pane mashoma sarudzo kunze uko, uye haasi iwo mutyairi mukuru mumutengo wekutanga weiyo inverter," akadaro."Zvisinei, izvi hazviwanzo kushambadzirwa zvakanyanya inverter maficha, pamwe nekuti musoro wacho wakanyanya, hunyanzvi, kana kunyange [nekuti] PID pachayo yakaoma kuona mumunda.Saka isu tinoona mamwe asina transformer inverters anouya asina basa iri. "
Asi kudzikisira PID kuchatonyanya kukosha sezvo makambani ezuva ave nesarudzo yekutora mutero wekugadzira mutero (PTC) muIRA.Kuchengeta kudzikisira mukutarisa kuitira kuti ma modules abudise simba rakakura kwenguva yakareba sezvinobvira kuchave kwakakosha kune chokwadi chechikwereti chemutero.
"Ini ndinofunga kuva neindasitiri yakapararira kunzwisisa kwezvinhu zviri muPID zvimwe ndizvo zvinoda kuwedzera - dzidzo nezvenguva idzo ma modules ako angangove akajairwa nePID, pamwe nekuona nzira," Marsh akadaro.
