Muri iki gihe gishya cy’ingufu, sisitemu zo kubika ingufu ni ingenzi cyane mu gukoresha neza ingufu. Capacitors za YMIN, hamwe n’imikorere yazo myiza, ni ingenzi mu kunoza uburyo bwo kubika ingufu buhamye, bunoze kandi bwizewe. Izi zikurikira ni inshingano zazo z’ingenzi mu buryo bwo kubika ingufu:
1. Ihuriro ry'Ingufu rya Power Converter (PCS)
Imashini zihindura ingufu zigomba kugira uruhare mu guhindura ingufu mu cyerekezo cy’ibiri hagati ya bateri na grid. Capacitors za YMIN zigira uruhare runini muri iki gikorwa:
• Ububiko bw'ingufu nyinshi: Ifata ingufu z'amashanyarazi vuba kandi ikayirekura kugira ngo igabanye ihindagurika ry'amashanyarazi, bigatuma sisitemu ikomeza gukora. Itanga kandi uburyo bwo kwishyura ingufu zikoreshwa mu gutwara imizigo no kunoza imikorere ya moteri.
• Uburinzi bwa voltage nyinshi cyane: Ihangana n'amashanyarazi menshi kuva kuri 1500V kugeza kuri 2700V, ifata amashanyarazi menshi, kandi ikarinda ibikoresho by'amashanyarazi nka IGBT na SiC kwangirika.
• Uburinzi bw'umuvuduko w'amashanyarazi menshi: Igishushanyo cya ESR kiri hasi (kugeza kuri 6mΩ) gifata neza umuvuduko w'amashanyarazi mwinshi kuri DC-Link, gitunganya uburyo bwo kugenzura ingufu, kandi gishyigikira gutangira buhoro kugira ngo kigabanye impanuka y'ibikoresho.
2. Iterambere ry'amashanyarazi ku bahindura amashanyarazi
Mu byuma bihindura ingufu zisubira nk'ingufu za photovoltaic n'umuyaga, capacitors za YMIN zitanga:
• Ubucucike bw'umuvuduko mwinshi: Kubika umuriro mwinshi kuri buri gipimo cy'amashanyarazi byongera imikorere myiza yo guhindura DC-kuva kuri AC.
• Gutunganya Harmonic: Umuriro mwinshi ugabanya imbaraga zisohoka, bigatuma ingufu zihujwe n'umuyoboro w'amashanyarazi ziba nziza.
• Guhindagurika k'ubushyuhe: Ubushyuhe bwinshi bwo gukora (-40°C kugeza +125°C) butuma imikorere ihoraho mu bidukikije birimo ubushyuhe bwinshi.
3. Uburinzi bw'umutekano ku buryo bwo gucunga bateri (BMS)
Muri BMS, capacitors za YMIN zirinda umutekano wa bateri binyuze mu buryo butatu:
• Kugereranya Voltage: Bihujwe hamwe na bateri, bihindura mu buryo bwikora itandukaniro ry'voltage y'uturemangingo kugira ngo bateri yongere igihe cyo kubaho.
• Igisubizo cy'igihe gito: Ubushobozi bwazo bwinshi butuma ingufu zisohoka ako kanya kugira ngo zihure n'ubwiyongere butunguranye bw'umutwaro kandi hirindwe ko zisohoka cyane.
• Uburinzi bw'amakosa: Bakora nk'isoko y'amashanyarazi y'inyongera, bakomeza gukora neza mu gihe sisitemu yangiritse, bagahita bahagarika amasano yose ashobora kwangirika.
4. Supercapacitors: Bifitanye isano n'umutekano n'ubuzima burambye
Module za YMIN supercapacitor zitanga uburyo bushya bwo kwirinda aho gukoresha bateri za lithium zisanzwe:
• Umutekano wo hejuru: Nta muriro cyangwa guturika mu gihe habayeho gutobora, gusya, cyangwa gufunga amashanyarazi, byemejwe ko bifite umutekano mu modoka.
• Imara igihe kirekire, Idakoreshwa mu kubungabunga: Igihe cy'urugendo kirenga uruziga 100.000, cyongera igihe cyo gukora kugeza ku myaka ibarirwa muri za mirongo, aho ikoreshwa ry'ingufu zitanye riri hagati ya 1–2μA.
• Guhuza n'ubushyuhe buke: Ingufu zihoraho mu bushyuhe bukabije bwa -40°C, zikemura ibibazo byo kuzimya ubukonje ku bikoresho bya smart meter n'ibikoresho biri mu ndege.
Umwanzuro
Capacitors za YMIN, zifite ibyiza by'ingenzi byo kudakoresha ingufu nyinshi, ubushobozi bunini, kuramba, n'umutekano udasanzwe, zihujwe cyane n'ibikoresho bihindura ingufu, inverters, BMSs, na supercapacitor modules bya sisitemu yo kubika ingufu, bikaba inkingi ikomeye yo guhindura ingufu neza no kuzicunga neza. Ikoranabuhanga ryabo ntirituma sisitemu yo kubika ingufu igera mu gihe "kitarangwaho kubungabunga" gusa, ahubwo rinatuma isi yose yihuta ikagera ku miterere y'ingufu zikomoka ku bidukikije, zifite ubwenge kandi zizewe.
