Urwego rwibice byihuta byo guhagarika PLC igenzura ni igikoresho gifatanya nu rwego rwo murwego rwo kuzimya umuriro byihuse kugirango habeho sisitemu yo gufotora DC kuruhande rwihuta, kandi igikoresho gihuza na kodegisi y’amashanyarazi yo muri Amerika NEC2017 & NEC2020 690.12 kugirango ihagarike byihuse. amashanyarazi.Ibisobanuro bisaba ko sisitemu ya Photovoltaque ku nyubako zose, kandi umuzenguruko urengeje metero 1 (305 mm) uhereye kuri moderi ya fotovoltaque, ugomba kugabanuka munsi ya 30 V mumasegonda 30 nyuma yo guhagarika byihuse;Umuzunguruko uri muri metero 1 (305 mm) uhereye kuri PV module array igomba kugabanuka munsi ya 80V mumasegonda 30 nyuma yo gutangira byihuse.Umuzunguruko uri muri metero 1 (305 mm) uhereye kuri PV module array igomba kugabanuka munsi ya 80V mumasegonda 30 nyuma yo gutangira byihuse.
Sisitemu yo murwego rwo kuzimya sisitemu yihuta ifite sisitemu yo guhagarika no guhagarika imirimo.Hashingiwe ku kuzuza ibisabwa byihuse byo guhagarika ibikorwa bya NEC2017 & NEC2020 690.12, irashobora kongera ingufu z'amashanyarazi ya sisitemu yo kubyara amashanyarazi no kuzamura umuvuduko w'amashanyarazi.Iyo ingufu z'amashanyarazi ari ibisanzwe kandi ntihabeho guhagarika byihutirwa, urwego urwego rwihuta rwo guhagarika PLC igenzura agasanduku kazohereza itegeko ryo gufunga amashanyarazi yihuta binyuze mumurongo w'amashanyarazi kugirango uhuze buri kibaho gifotora;Iyo amashanyarazi akomeye yahagaritswe cyangwa guhagarara byihutirwa byatangiye, ibice-urwego rwihuta rwo guhagarika PLC igenzura agasanduku kazohereza itegeko ryo guhagarika ibikorwa byihuta byihuta binyuze mumurongo wamashanyarazi kugirango uhagarike buri kibaho gifotora.
Urwego-rwihuta rwo guhagarika PLC igenzura agasanduku nigikoresho gikoreshwa muri sisitemu ya Photovoltaque (PV) kugirango byorohereze imikorere yihuse kurwego rwibigize.Guhagarika byihuse nibisabwa byumutekano bigamije kugabanya ingaruka ziterwa namashanyarazi mugihe cyihutirwa cyangwa ibikorwa byo kubungabunga.
Hano hari ingingo zingenzi zerekeye ibice-urwego rwihuta rwo guhagarika PLC igenzura:
Intego: Intego yibanze yikintu-urwego rwihuta rwo guhagarika PLC igenzura agasanduku ni ugushoboza guhagarika byihuse imikorere ya sisitemu ya PV.Guhagarika byihuse bivuga ubushobozi bwo kwihutisha ingufu za DC ya sisitemu ya PV, kugabanya voltage kumasoko kugera kurwego rwumutekano mugihe cyibihe byihutirwa cyangwa mugihe imirimo yo kubungabunga isabwa.
PLC (Programmable Logic Controller): PLC ni mudasobwa ya digitale ikoreshwa mugucunga no gukoresha inzira zitandukanye.Mu rwego rwo kugenzura byihuse kugenzura agasanduku, PLC ikoreshwa mugukurikirana no kugenzura imikorere yihuse ya sisitemu ya PV.Yakiriye ibimenyetso bivuye mubikoresho byo hanze kandi itangiza inzira yo guhagarika.
Agasanduku k'ubugenzuzi: Agasanduku k'ubugenzuzi karimo uruziga rukenewe, ibice, hamwe ninteruro kugirango ushyire mubikorwa byihuse.Mubisanzwe harimo inyongeramusaruro zo kwakira ibimenyetso bivuye mubikoresho byo hanze, nkibitangira byihuse byihuta cyangwa byihutirwa byihutirwa, nibisohoka kugirango bigenzure ihagarikwa rya sisitemu ya PV.
Ibice-Urwego Ruzimya: Sisitemu-urwego rwihuta rwo guhagarika sisitemu ikubiyemo guhagarika ibice cyangwa ibice bya sisitemu ya PV, aho guhagarika sisitemu yose.Ibi bituma abashinzwe ubutabazi cyangwa abakozi bashinzwe kubungabunga bakorera neza ahantu runaka batiriwe bahura n’umuvuduko mwinshi.
Kubahiriza Kode n'Ubuziranenge: Ibisabwa byo guhagarika byihuse bisobanurwa kode y'amashanyarazi n'ibipimo ngenderwaho, nka Kode y'igihugu y'amashanyarazi (NEC) muri Amerika.Urwego-rwihuta rwo guhagarika PLC igenzura agasanduku igomba kubahiriza aya mabwiriza kugirango sisitemu ya PV yujuje ibyangombwa bisabwa byumutekano.
Kwishyira hamwe: Ibigize-urwego rwihuta rwo guhagarika PLC igenzura ryinjijwe muri rusange gahunda ya PV yo kugenzura no kugenzura ibikorwa remezo.Ihuza nibindi bice bigize sisitemu, nka inverter cyangwa sisitemu yo kugenzura, kugirango ihuze inzira yihuse.
Ni ngombwa kugisha inama umuhanga wamashanyarazi cyangwa PV sisitemu yububiko kugirango tumenye neza guhitamo, kwishyiriraho, no guhuza ibice-urwego rwihuta rwo guhagarika PLC igenzura agasanduku.Kubahiriza amategeko n'amashanyarazi yaho bigomba gukurikizwa kugirango umutekano wizewe wa sisitemu ya PV.
Murakaza neza kutugisha inama kubisabwa byihariye kuri Rapid Shutdown PLC Igenzura
