Amasistimu okugcina amandla adlala indima ebalulekile kumagridi kagesi wesimanje, avumela ukuhlanganiswa kwemithombo yamandla avuselelekayo, athuthukise ukuqina kwegridi, kanye nokuhlinzeka amandla ayisipele ngesikhathi sokucisha. Kodwa-ke, lezi zinhlelo zisengcupheni yokulimala ngenxa yokuphakama kwamandla, okungenzeka ngenxa yokushaya kombani, ukushintsha ukusebenza, noma ukuphazamiseka kwegridi. Ukuvikelwa kwe-surgery kubalulekile ukuze uqinisekise ukuphepha, ukwethembeka, nokuphila isikhathi eside kwamasistimu okugcina amandla.
Ukuvikela Izingxenye Ezibalulekile
Amasistimu okugcina amandla aqukethe izakhi ezahlukahlukene ezibalulekile, kufaka phakathi amabhethri, ama-inverter, amasistimu okulawula, kanye nemishini yokuqapha. Lezi zingxenye ziyazwela kuma-voltage spikes futhi zingalinyazwa ukukhuphuka kwamandla. Isibonelo, amabhethri asengozini yokubaleka ngokushisa kanye nokonakaliswa kweseli uma engaphansi komthamo omkhulu. Iziguquli, eziguqula amandla e-DC asuka kumabhethri abe amandla e-AC, angakwazi ukungasebenzi kahle noma ahluleke uma evezwe ekuhlinzekweni. Amadivayisi okuvikela i-Surge (ama-SPD) angavikela lezi zingxenye ngokuphambukisa i-voltage eyeqile kude nezinto ezibucayi.
Izingxenye Ezibalulekile Ezisengozini Yokwanda Kokulimala
- Amabhethri:
- Isengozini yokugcwala ngokweqile okubangelwa ukunyuka kwangaphandle, okungaholela ekubalekeni okushisayo, ukuvuza kwe-electrolyte, kanye nokuwohloka kwamaseli.
- Amaphutha angaphakathi noma amasekhethi amafushane ngaphakathi kwesistimu yebhethri angaphinda akhiqize ukukhuphuka kwamanje okuphezulu, kulimaze amaseli ebhethri.
- Ama-Inverters:
- Guqula amandla e-DC asuka kumabhethri abe amandla e-AC ukuze asetshenziswe ohlelweni lukagesi.
- Izwela kuma-voltage spikes futhi ingonakaliswa ukukhuphuka, okuholela ekuphelelweni kwesikhathi kwesistimu kanye nokulungiswa okumba eqolo.
- Izinhlelo Zokulawula:
- Lawula ukusebenza nokusebenza kwesistimu yokugcina amandla.
- Isengozini yokuphazanyiswa yi-electromagnetic interference (EMI) kanye ne-radio frequency interference (RFI) okubangelwa ukushaya kombani noma okokusebenza kukagesi okuseduze, okungaphazamisa ukuxhumana nokulawula amasignali.
- I-Protection Relay:
- Gada amapharamitha kagesi wesistimu futhi uqale izenzo zokuvikela uma kwenzeka kukhona okungavamile.
- Isengozini yokulimala ngenxa ye-overvoltage noma ukuphakama okuphezulu kwamanje, okuphazamisa amandla abo okubona nokusabela kumaphutha.
- Izisetshenziswa Zokuqapha Nokuxhumana:
- Qinisekisa ukuqapha nokuxhumana okufanele phakathi kwesistimu yokugcina amandla kanye negridi noma isikhungo sokulawula.
- Ithambekele ekulimaleni ngenxa yokwanda, okuthinta ukudluliswa kwedatha nokusebenza kwesistimu.
Ukubaluleka kokuvikelwa kokuhlinzwa
- Ukwehluleka ukuvikela lezi zingxenye kungase kubangele ukuncipha kwesikhathi, ukuncipha kokusebenza kahle kwesistimu, nokulungiswa okubizayo noma ukushintshwa.
- Izinyathelo ezifanele zokuvikela ukukhuphuka zingavikela lezi zingxenye, ziqinisekise ukuphepha, ukwethembeka, nokuphila isikhathi eside kwamasistimu okugcina amandla.
