Porogarama z’igerageza zigabanya ingorane zo gushirwa mu ngiro. Ivyumba birashobora gukoresha uburyo bwa bateri ku mirongo yihariye y'ibikorwa imbere y'uko ivyumba-bikoreshwa hose. Abo bapilote berekana ko bagabanya igihe co guhagarara mu gihe batanga ubumenyi mu bijanye n’ibikorwa bumenyesha ingamba zagutse zo gukoresha.
Itegeko ry’ubufatanye rivuga ku migenderanire n’ibikoresho biriho. Uburyo bw’amabateri butegerezwa guhuza n’uburyo bwo gucunga inyubakwa, uburyo bwo kugenzura amageneratore, n’ibisabwa vyo guhuza ibikoresho. Ugushiramwo neza birabuza amakimbirane yoshobora gutuma ibikorwa vy’ububiko bihungabana mu gihe c’uguhagarara kw’amashanyarazi.
Porogarama z’amahugurwa zitegura abakozi ku bijanye n’ugukoresha ubuhinga n’ugutanga inyishu zihutirwa. Naho ubuhinga bwa bateri bukora bwigenga mu bihe bisanzwe, abakozi barakeneye gutahura uburyo bwo gukoresha amaboko, uburyo bwo gutorera umuti ingorane, no guhuza utwigoro two gusubizaho ibikoresho. Imyimenyerezo idasanzwe iratuma umuntu aguma yiteguye mu bijanye n’ishirahamwe.
Amabwirizwa n'umutekano
Ibikoresho vyo kubika inguvu za bateri bitegerezwa kwubahiriza amategeko y'umuyagankuba n'ingingo ngenderwako zo gukingira umuriro. Ishirahamwe ry’igihugu ry’ugukingira umuriro (NFPA) 855 ritanga ibisabwa kugira ngo umuntu ashobore gushiramwo, gukoresha no gutunganya. Icemezo ca UL 9540 kigaragaza ko umuntu yubahiriza amategeko agenga ivy’ugupima umutekano.
Uburyo bwo gutanga uruhusha buratandukanye bivanye n’ububasha. Inzego z’intara zifise ububasha (AHJ) zisubiramwo imigambi yo gushiramwo ibintu kugira ngo zibe zihuye n’amategeko. Gukorana n’aba AHJ hakiri kare birabuza gucererwa mu gihe co gutumwa. Hari uturere twatunganije neza ivyemezo vy’imigambi yo kubika inguvu mu gihe c’ubushobozi bumwe bumwe.
Ivyiyumviro vy’ubwishingizi biragira ico bikoze ku mahitamwo y’imiterere y’uburyo. Abashingira intahe barasuzuma uburyo bwo kuzimya umuriro, ubushobozi bwo gucunga ubushuhe, n’ibikorwa remezo vyo kugenzura. Ivyumba bihitamwo imiti y’amabateri ifise imiterere myiza y’umutekano birashobora guhabwa amasezerano meza y’ubwishingizi.
Amasezerano yo guhuza uruzitiro agenga ingene amabateri akorana n'inguvu z'amazi. Ivyumba bigira uruhara muri porogarama zo gusubiza ibisabwa canke amasoko y’ubudandaji bisaba inyigisho zisanzwe z’uguhuza n’amasezerano y’ibikorwa. Mbere n'ubuhinga bwo gusubiza inyuma-gusa burakeneye imenyekanisha ry'ubuhinga kugira ngo bubone ko ubuhinga bwo gukingira buhuye neza.
Amabwirizwa agenga ibidukikije avuga ku guta amabateri no kuyasubiramwo. Bateri za litiyumu-ion zirimwo ibikoresho bisaba gucungera neza iherezo-ry'ubuzima. Abahinguzi bararushiriza gutanga porogarama zo gusubira gukoresha ibihimba vy’amabateri, zigafunga uruzitiro rw’ibikoresho kandi zigashigikira ingingo ngenderwako z’ubutunzi buzunguruka.
Gupima Ubushobozi bwo Kugabanya Igihe co Guhagarara
Gukurikirana ibipimo vyemeza ingaruka z'ishoramari ry'ububiko bw'inguvu z'inganda. Ivyumba bikwiye gushinga imibare y’igihe co guhagarara imbere y’uko bikoreshwa no gukurikirana amahinduka inyuma y’aho. Ivyerekana ibikorwa nyamukuru birimwo incuro umuntu akora, igihe amara, n’ibiciro bijana.
Igihe hagati y’ibinanirwa (MTBF) gipima ukwizigirwa kw’urutonde mu gihe. Ivyuma vy’ububiko bw’amashanyarazi mu nganda bikwiye kwerekana ko MTBF iriko iragwira uko uburyo bwo gucungera amashanyarazi buzibira ibikoresho bifitaniye isano n’amashanyarazi-ugusenyuka. Gukurikirana iyi metric bipima agaciro ko kwirinda igihe co guhagarara.
Ijanisha ry'ukuboneka ryerekana igihe sisitemu ikoresha ugereranije n'amasaha y'ibikorwa. Igikoresho gifise intumbero yo kuronka 99,9% ("icenda zitatu") gishobora kwihanganira amasaha 8,76 gusa y'uguhagarara ku mwaka. Ububiko bw’inguvu z’inganda bushoboza urugero rwo kuboneka butanga agaciro k’ubudandaji gashobora gupimwa ku bibanza bifise ibisabwa bikomeye vy’igihe co gukora.
Ivyiyumviro vy'ubutunzi bihindura igihe co guhagarara mu majambo y'ivy'amahera. Ivyiza biva mu biharuro vy’ishoramari bikwiye kubamwo ukwirinda amafaranga y’igihe co guhagarara, kugabanya amafaranga y’ugusaba, no kuzigama inguvu z’ubukemurampaka. Isesengura ryuzuye rifata agaciro ka sisitemu yose irenze imikorere yoroshe yo gusubiza inyuma.
Isesengura ry’ukugereranya rigereranya ibikorwa n’ingingo mfatirwako z’inganda. Ivyumba birashobora kugereranya imibare y’igihe bihagarara n’imibare y’imice kugira ngo bimenye ingene bikora. Ibikorwa vyiza vyerekana ingamba nziza zo kwirinda igihe co guhagarara harimwo no gukoresha ububiko bw’inguvu z’inganda.
Isesengura ry’imizi y’ibintu vyasigaye mu gihe c’uguhagarara rigaragaza uturyo two kwongerako ivyo gutera imbere. Naho ububiko bw’amashanyarazi bw’inganda bukuraho igihe co guhagarara gifitaniye isano n’amashanyarazi, ibikorwa birashobora guhagarara bitewe n’ugusenyuka kw’ibikoresho, ukubura ibikoresho, canke amakosa y’abantu. Gutorera umuti ivyo bintu biciye mu nzira z’inyongera bituma igihe cose umuntu akora kirushiriza kuba kinini.
Ibibazo bikunze kwibazwa
Ni gute ubuhinga bwo kubika amashanyarazi mu nganda bushobora kwihuta gusubiza iyo amashanyarazi azimye?
Uburyo bwo kubika inguvu za bateri burahindukira bukaja mu buryo bwo kubika mu gihe c’isegonda imwe. Iryo nyishu ry’aho nyene ribuza ibikoresho guhagarara no gutakaza amakuru bishika mbere n’igihe amashanyarazi ahagaze mu gihe gito. Amageneratore ya dizeli ya kera asaba amasegonda 10-15 kugira ngo atangure guhagarara neza, ivyo bikaba bituma habaho ikinogo ububiko bw’amashanyarazi bw’inganda bukuraho.
Ni igihe ikihe co gusubiza inyuma ibikorwa vyinshi vy’inganda bikeneye?
Amashanyarazi menshi azima mu nganda amara amasaha 2-4, ivyo bikaba ari vyo ubuhinga bwo kubika amashanyarazi mu nganda bushobora kubitanga bitagoranye. Ivyumba bikwiye gupima ubunini bw’imirongo bishingiye ku mibare y’uguhagarara kw’amashanyarazi mu karere n’ibisabwa vy’umuzigo ukomeye. Ivyiyumviro vy’ibice bishobora kwaguka iyo isesengura ryerekanye ko bikenewe ko umuntu afata igihe kirekire co gucungera.
Mbega amabateri yoshobora gukorana n’amageneratore asanzweho?
Uburyo bwo kubika amashanyarazi mu nganda bufatanya n’amageneratore ya dizeli kugira ngo haboneke inyishu z’ububiko bw’amashanyarazi. Bateri itanga ubushobozi ubwo nyene igihe umuyagankuba uriko uratangura, canke umuyagankuba urashobora gusubiramwo umuriro kugira ngo wongere igihe co gucungera umuriro mu gihe umuyagankuba uhagaze igihe kirekire. Ivyo bihuza bituma ubuhinga bwompi bugira inkomezi nyinshi.
Ni gute ububiko bw’inguvu z’inganda bugabanya igihe co guhagarara kirenze inguvu z’inyuma?
Ubuhinga bwa bateri burabuza igihe co guhagarara biciye mu gushavura, gutunganya umuriro, no guhindura umuzigo. Ubwo bushobozi burinda ibintu bishobora gushika aho ibibazo vy’uburyo bw’amashanyarazi canke ubukene bw’ubushobozi bituma umusaruro ugabanuka. Ivyuma bigabanya ukwizigira ugushikama kw’uruzitiro mu gihe bigabanya ibiciro vy’inguvu.
Ni ivyemezo ibihe vy’umutekano ibibanza bikwiye gusaba?
Rondera icemezo ca UL 9540 n’ukubahiriza NFPA 855. Izo ngingo ngenderwako zivuga ku mutekano w'umuriro, umutekano w'umuyagankuba, n'ibisabwa mu gukoresha. Ivyuma vy’amabateri vy’i Litiyumu (LiFePO4) bitanga ubushuhe bwo gukomera ugereranije n’ivyuma vy’i Litiyumu -ion.
Ivyo bikoresho vyo kubika amabateri mu nganda bimara igihe kingana iki?
Uburyo butunganijwe neza buratanga imyaka 15-25 y’igikorwa. Ubuhinga bwo gucunga bateri bugenzura ubuzima bwiza no gutunganya uko zishaja kugira zibeho igihe kirekire. Gukurikirana kure bishoboza gucungera imbere y’igihe bishobora gukingira ukunanirwa no gutuma habaho uburinzi buhoraho mu gihe co guhagarara mu buzima bwose bwa sisitemu.
