Imboni yokugcina amandla iyingxenye ebalulekile yesistimu yamandla yesimanje. I-inverter idlala izindima eziningi ohlelweni lwesimanje lokugcina amandla, okuhlanganisa ukuguqulwa kwamandla, ukulawula nokuxhumana, ukuvikelwa kokuhlukaniswa, ukulawula amandla, ukushaja nokukhipha amandla okubili, ukulawula okuhlakaniphile, ukuvikelwa okuningi kanye nokuhambisana okuqinile, okwenza i-inverter ibe ngenye yezingxenye ezibalulekile zesistimu yokugcina amandla.
Ama-inverter okugcina amandla ngokuvamile akhiwa izinhlelo zokufaka, zokukhipha kanye nezokulawula. Ama-capacitor adlala indima ku-inverter, okuhlanganisa ukuzinza nokuhlunga kwamandla kagesi, ukugcinwa nokukhululwa kwamandla, ukuthuthukisa amandla, ukuvikelwa kanye nokwenza kube bushelelezi i-DC pulsation. Lokhu kusebenza ndawonye kuqinisekisa ukusebenza okuzinzile kanye nokusebenza kahle okuphezulu kwe-inverter. Kuzinhlelo zokugcina amandla, ingathuthukisa ukusebenza kahle kanye nokuzinza kwesistimu iyonke.
Izinzuzo zama-capacitor e-YMIN kuma-inverters
Ubuningi bomthamo ophezulu:
I-inverter ithola ugesi okhiqizwa ngamadivayisi wamandla avuselelekayo njengamaphaneli elanga noma ama-wind turbine bese iwuguqula ube uhlobo lukagesi oluhlangabezana nesidingo. Kule nqubo, njengoba umthamo womthwalo unganda ngokushesha, i-inverter idinga ukuba namakhono okulawula amandla aqinile ukuqinisekisa ukuthi ugesi uphuma kahle.
Ama-capacitor e-electrolytic e-aluminium e-YMINZinenzuzo yobuningi obukhulu bomthamo, okungagcina ukushaja okwengeziwe ngobuningi obufanayo, kuhlangatshezwane ngokugcwele nesidingo samandla omthwalo esingase sikhule ngokushesha. Ekusebenzeni kwe-inverter, lesi sici siqinisekisa ukukhishwa kwamandla kagesi okubushelelezi.
Ukumelana kwamanje okuphezulu kwe-ripple:
Ngesikhathi sokusebenza kwe-inverter, uma ukulungiswa kwamandla kungenziwa, ugesi ekuphumeni kwawo ungase uqukathe inani elikhulu lezingxenye ze-harmonic. Ama-capacitor e-electrolytic e-YMIN aluminium, anokumelana kwawo okuphansi kochungechunge olulinganayo (i-ESR) kanye nezici ezinhle kakhulu zemvamisa ephezulu, anganciphisa ngempumelelo okuqukethwe kwe-harmonic, hhayi nje ukuhlangabezana nesidingo somthwalo samandla e-AC asezingeni eliphezulu, kodwa futhi aqinisekise ukuthi i-inverter ihambisana nezindinganiso ezifanele zokufinyelela kwegridi, ukunciphisa ukuphazamiseka kanye nomthelela omubi kugridi.
Ngaphezu kwalokho, ohlangothini lokufaka lwe-DC lwe-inverter, ama-capacitor e-YMIN, anomthamo ophezulu kanye nokusebenza kahle kokuhlunga, angahlunga umsindo nokuphazamiseka ekuhlinzekweni kwamandla kagesi e-DC okufakwayo, aqinisekise ukuthi ugesi wokufaka uhlanzekile, ngaleyo ndlela anciphise umthelela wezimpawu zokuphazamiseka ezingxenyeni ezilandelayo zesekethe ye-inverter futhi athuthukise ngokuphelele ukuzinza nokusebenza kahle kohlelo.
Inzuzo yokumelana ne-voltage ephezulu:
Ngenxa yezinguquko ekukhanyeni, i-voltage yokukhipha yesistimu ye-photovoltaic ingase ingazinzile, futhi amadivayisi e-semiconductor yamandla ku-inverter nawo azokhiqiza ama-voltage nama-current spikes ngesikhathi senqubo yokushintsha. Lawa ma-spikes angabangela umonakalo kumadivayisi kagesi. Ngakho-ke, i-buffer capacitor idlala indima ebalulekile ekumunceni ama-voltage nama-current spikes nokuvikela amadivayisi kagesi kuma-voltage amaningi noma ama-current shocks. Ngesikhathi esifanayo, i-capacitor ingakwazi ukushelela izinguquko kuma-voltage nama-current, inciphise ukulahlekelwa kwamandla ngesikhathi senqubo yokushintsha, ngaleyo ndlela ithuthukise ukusebenza kahle kokuguqulwa kanye nokuzinza okuphelele kwe-inverter.
I-YMINisincomo sokukhetha i-capacitor ku-inverter:
Fingqa:
Ama-capacitor e-YMINithuthukise ngokuphelele ukusebenza kwama-inverters ezinhlelweni zokugcina amandla ngezici zawo ezinhle kakhulu njengokumelana ne-voltage ephezulu, ukuminyana kwamandla aphezulu, i-ESR ephansi, kanye nokumelana kwamanje okunamandla kwe-ripple. Akugcini nje ngokunciphisa ukulahlekelwa enqubweni yokuguqulwa kwamandla ngokusebenzisa izici ezinhle kakhulu zokuhlunga kanye nokulawula i-voltage, kodwa futhi kungalungisa i-voltage, i-current kanye nemvamisa ukuqinisekisa ukuthi uhlelo luphuma ngokwethembeka. Ngesikhathi esifanayo, ama-capacitor amunca ngokushesha ukushaqeka kwesikhashana kanye nokushaya kwe-voltage okubushelelezi, okuthuthukisa ukulwa nokuphazamiseka kanye nokuzinza kwesistimu. Ngaphezu kwalokho, ama-capacitor e-YMIN asekela ngempumelelo ukugcinwa nokukhululwa kwamandla ngesikhathi senqubo yokushaja nokukhipha amandla, okwandisa ukusebenza kahle kokusetshenziswa kwamandla kwesistimu yokugcina amandla futhi kusize lonke uhlelo ukuthi lufinyelele ukusebenza kahle kokuguqulwa okuphezulu, ukuzinza okuqinile, kanye nokulahlekelwa amandla okuphansi.
