Isiganeko kunye neBhlog

Kwimeko-bume eguquka ngokukhawuleza yeenkqubo zamandla zoshishino zanamhlanje, ngaba ujongene nokusilela kwezixhobo okungachazekiyo? Ngaba iindleko zakho zenyanga zinyuswa zisohlwayo esiphezulu samandla? Okanye mhlawumbi ii-transformers zakho zishushu kwaye zingxolo nangona zingasebenzi ngokupheleleyo? Ukuba ezi ngxaki zivakala ziqhelekile, kusenokwenzeka ukuba ujongene nombane ombi kunye nongcoliseko lombane.

Umgangatho ophantsi wombane ubangela ilahleko enkulu yemali kumashishini kwihlabathi liphela. Oku kukhokelela ekuvalweni kweeseva, konakalisa izixhobo zonyango ezibuthathaka, kwaye kuphazamisa kakhulu imveliso yemizi-mveliso. Ungcoliseko oluhambelanayo kwigridi yombane sesona sizathu siphambili sezi ngxaki. Uphando lubonisa ukuba umgangatho ophantsi wombane ubiza amashishini aseYurophu ngaphezulu kwe-€150 yeebhiliyoni ngonyaka [1].

Xa iSiemens yathumela ii-dynamic voltage restorers kwiBerlin Gigafactory yaseTesla, naxa iState Grid Corporation yaseTshayina yaseka iqonga elibanzi lokujonga umgangatho wamandla kwiXiong'an New Area, imakethi yomgangatho wamandla yehlabathi yayisanda ngokuzolileyo ngesantya sokukhula konyaka se-9.2%.

Ukugcinwa kwamandla orhwebo kunceda iifektri ukuba zisebenzise amandla elanga amaninzi kwaye zinciphise iindleko zombane. Igcina amandla elanga emini kwaye iwasebenzise kamva xa imfuno iphezulu.

Ukusilela kwebhanki ye-capacitor eMzantsi Afrika ngoku yingxaki enkulu kwiindawo zoshishino nezorhwebo. Izibonelelo ezininzi zisebenzisa ii-solar inverters, ii-variable speed drives, ii-UPS units, kunye nezinye izixhobo ze-elektroniki zamandla.

Ukwenziwa kweglasi kubandakanya iinkqubo zokufudumeza eziqhubekayo kunye neenkqubo ezintsonkothileyo zokwenza izinto ngokuzenzekelayo. Ezi zixhobo zixhomekeke kakhulu kwiVariable Frequency Drives (VFDs) kunye nabalawuli abakhulu beziko. Nangona kunjalo, ezi zixhobo ze-elektroniki ezinamandla zihlala zizisa imithwalo ebalulekileyo engeyiyo emgceni. Oku kuphumela ekuphazamisekeni kwe-harmonic okunokuphazamisa imigca yemveliso ebuthathaka.

Iifektri zezixhobo zisebenzisa oomatshini abanzima abanjengoomatshini be-CNC, iiyunithi ze-EDM, kunye neegrinder ezinesantya esiphezulu. Le mithwalo ayihambelani nomgca kwaye idala imingeni ebalulekileyo yomgangatho wamandla. Ngokukodwa, utshintsho olukhawulezileyo lomthwalo lubangela ukufiphala kwevolthi kunye namandla aphantsi.

Izakhiwo ezininzi zisasebenzisa ii-capacitor banks ukulungisa amandla, kodwa iinkqubo zamandla zanamhlanje zihlala zifuna isisombululo esinamandla ngakumbi. Kwiindawo ezinemithwalo engeyiyo emgceni, ukuphambuka kwe-harmonic, kunye neemeko ze-voltage ezitshintshayo, uthelekiso lwe I-SVG vs ibhanki ye-capacitoriba yinto ebaluleke ngakumbi.

Umbane ligazi lobomi kuluntu lwanamhlanje, unika amandla amakhaya, izikolo, izibhedlele, kunye nezakhiwo zoshishino. Ukuze iinkqubo zombane zisebenze ngokukhuselekileyo nangokufanelekileyo, umbane ozinzileyo awunakuxoxiswana ngawo. Ukuguquguquka—nokuba umbane uphezulu kakhulu okanye uphantsi kakhulu—kunokuphazamisa ukusebenza kwezixhobo, kunciphise ubomi bazo, okanye kubangele umonakalo ongenakuguqulwa. Eli nqaku lichaza iziseko zombane, izizathu zokuguquguquka, kunye nendlela i-Intonepower's Static Var Generator (SVG) esebenza ngayo njengesisombululo esithembekileyo sokugcina uzinzo lombane.

Kwiinkqubo zamandla zoshishino zanamhlanje, ii-variable frequency drives (ii-VFD) ziye zaba yinto efunekayo. Zigcina amandla, ziphucula ulawulo lwenkqubo, kwaye zinciphisa iindleko zokusebenza kwiimpompo, iifeni, iicompressor, kunye neenkqubo zokuhambisa.
