Sisitemu yo gutanga amashanyarazi y'ibitaro ni iy'uburyo rusange, arirwo rwego rwo gutanga amashanyarazi mu turere twose.Igishushanyo mbonera cy'ibitaro gikoresha ubwoko bwa kimwe cya kabiri, kandi umutwaro w'amashanyarazi ni uw'umutwaro.Ubwoko bwingenzi bwamashanyarazi burimo: sisitemu yo kumurika, sisitemu yo guhumeka, sisitemu yubuvuzi, sisitemu yo kumurika byihutirwa.
Sisitemu yo kumurika no guhumeka nikintu nyamukuru gikurura ingufu muburyo butandukanye bwo gukoresha amashanyarazi mubitaro, bizatanga ibitekerezo byinshi bihuza imiyoboro y'amashanyarazi y'ibitaro mugihe ikoreshwa.Bitewe no gukoresha ubwoko bushya bwamashanyarazi nka mashini ya X-ray, imashini ya magnetiki resonance imashini MRI, imashini ya CT, nibindi, gukoresha amashanyarazi, guhinduranya UPS nindi mibare myinshi yimizigo idafite umurongo, nabyo bitanga ibitekerezo bihuza kuri amashanyarazi.
Ibitaro bifite amashanyarazi menshi, kandi ibikoresho bya sisitemu bifite umutekano kandi byizewe nkibintu byambere.Bitewe no gukoresha cyane umutwaro udafite umurongo, imiterere iranga icyiciro cya 3, icya 5 nicya 7 bikorerwa cyane cyane mumashanyarazi yibitaro.Harmonics igira ingaruka itaziguye kumikorere ihamye yibikoresho byubuvuzi byuzuye, kandi kwegeranya guhuza 3 kumurongo utabogamye bitera ubushyuhe kumurongo wo hagati, ibyo bikaba byangiza imikorere yumuriro wibitaro byibitaro.
2. Ibisobanuro n'ibisekuruza bihuza
Igisobanuro cyubwuzuzanye: Urukurikirane rwa Fourier rwangirika rwigihe cya sinusoidal ntarengwa, usibye kubona ibice bimwe nkinshuro shingiro yumurongo wamashanyarazi, ariko kandi nuruhererekane rwibice birenze ibice byinshi byibanze byinshyi zingufu zimbaraga. gride, iki gice cyamashanyarazi cyitwa guhuza.
Igisekuru cyubwuzuzanye: Iyo ikigezweho kinyuze mumuzigo, habaho umubano utari umurongo hamwe na voltage yumutwaro, ikora umuyaga utari sinusoidal, bikavamo guhuza.
3. Ibibi byo guhuza
1) Guhuza biganisha ku kunanirwa kw'amashanyarazi bidakwiye n'impanuka zo guhagarika ibikoresho ziterwa no gukoresha nabi cyangwa kwanga kurinda ibikoresho byikora, bikaviramo igihombo kinini.
2) Kwiyongera kwinshuro zumuvuduko uhuza bitera ingaruka zigaragara zuruhu, byongera imbaraga zinsinga zinsinga zamashanyarazi nimirongo ikwirakwizwa, byongera umurongo, gutakaza ubushyuhe, gusaza imburagihe, kugabanya ubuzima, bigatera kwangirika, kandi ikunda guhura nubutaka bugufi bwumuzunguruko, bigatera inkongi yumuriro.
3) Gutera amashanyarazi ya gride resonance, biganisha kuri voltage ihuza kandi ikabije, gutera impanuka zikomeye, kwangiza ubushobozi bwa capacitori nibindi bikoresho byamashanyarazi.
4) Guhuza bigira ingaruka kumikorere isanzwe yibikoresho byamashanyarazi bitandukanye.Bitera igihombo cyiyongereye hamwe nubushyuhe bukabije bwa moteri na transformateur, hanyuma bigakurikirwa no kunyeganyega kwa mashini, urusaku na volvoltage, kugabanya imikorere no gukoresha, no kugabanya ubuzima bwa serivisi.
5) Kubangamira itumanaho ryegeranye, ibikoresho bya elegitoroniki cyangwa byikora byikora, cyangwa bigatuma bidashoboka gukora bisanzwe.
4. Gahunda yo kuyungurura
Ibitaro bikuru bya Shaanxi nicyiciro cya kabiri cyigihugu A ibitaro bifite ibikoresho byubuvuzi bigezweho kandi nibidukikije byiza.Abakozi bacu babigize umwuga na tekinike bashinzwe ibitaro hakiri kare gupima ubuziranenge bwumuriro w'amashanyarazi make y'ibitaro.Igipimo cyo kugoreka ibintu byose biri mumashanyarazi yibitaro ni 10%, bikwirakwizwa cyane cyane mubiranga imiterere ya 3, 5 na 7.Dukurikije ibisubizo byikizamini, isosiyete yacu yashyizeho urwego rwubushobozi bwa 400A igikoresho cyo kuyungurura ibikoresho byibitaro, byashyizwe muri transformateur ntoya ya voltage isohoka, hakoreshwa uburyo bwo kuvura bwibanze mugucunga neza.

5.1 Kumenyekanisha ibicuruzwa
Akayunguruzo gakomeye (/ noker-3-icyiciro-34-insinga-ikora-imbaraga-muyunguruzi-apf-ahf-kuri-dinamike-ihuza-indishyi-ibicuruzwa /) ni ubwoko bushya bwibikoresho bya elegitoronike bikoreshwa muguhagarika byimazeyo guhuza kandi indishyi imbaraga zidasanzwe, zishobora kwishyura indinganizo nimbaraga zihinduka mubunini ninshuro.
5.2 Ihame ry'akazi
Imizigo yimitwaro igaragara mugihe nyacyo na CT yo hanze, kandi agaciro gahuza kabarwa na DSP y'imbere.Binyuze mu kimenyetso cya PWM cyoherejwe kuri IGBT, inverter itanga imiyoboro ihuza ihwanye n'umutwaro uhuza kandi mu cyerekezo kinyuranyo mu mashanyarazi kugira ngo ihuze kandi igere ku ntego yo kweza amashanyarazi.
6 .Gukurikirana no gusesengura amakuru agenzura guhuza ibitaro
Inama y'Abaminisitiri
Amakuru ya APF (/ guhuza-indishyi-200400v-ikora-ihuza-filtri-ahf-module-gatatu-icyiciro-cy'ibicuruzwa /) indishyi ihuza ibitaro yakurikiranwe nisesengura ry’ubuziranenge bw’amashanyarazi CA8336 y’Ubufaransa, hamwe n’amakuru y’ubuziranenge bw’amashanyarazi byageragejwe muburyo bubiri bwibikorwa bya APF (nyuma yindishyi) no guhagarika (nta ndishyi), kandi amakuru yakusanyirijwe hamwe arasesengurwa.
6.1 Gupima no gusesengura ibya APFs (/ 3-icyiciro-3-insinga-ikora-imbaraga-muyunguruzi-400v-75a-apf-panel-progaramu /) kwinjiza no gukuraho amakuru

Nkuko bigaragara ku gishushanyo kiri hejuru, kugenzura guhuza ibitaro na AHF (/ imbaraga-nkeya-imbaraga-zikora-imbaraga-zungurura-kugabanya-guhuza-imbaraga-zikora-zihuza-zungurura-ahf-ibicuruzwa /) byapimwe hamwe na umwuga wimbaraga zisesengura CA8336 yubufaransa.Kugereranya amakuru mbere na nyuma ya APF byageragejwe.Nyuma yo gukoresha APF yacu kugirango igenzure neza, igipimo rusange cyo kugoreka (THDi) cyumuyoboro wibitaro byibitaro cyaragabanutse kiva kuri 10% kigera kuri 3%, kandi ingaruka ni nyinshi.
7. Incamake
Sisitemu yo gutanga amashanyarazi ni ngombwa.Kwinjiza ibikoresho bishya byamashanyarazi byazamuye cyane imikorere yubuvuzi nubuziranenge bwibitaro, kandi binatanga uburyo bwiza bwo kuvura abarwayi benshi.Ariko umutwaro mushya w'amashanyarazi nawo uzana umwanda uhuje.Kubaho guhuza byangiza imikorere isanzwe ya gride yamashanyarazi kandi bigira ingaruka kumutekano wibikoresho bivura neza.Mu rwego rwa sisitemu y’amashanyarazi rusange, guhuza byongera ikoreshwa ry’amashanyarazi mu bitaro, bikaba binyuranye n’amagambo y’igihugu yo guteza imbere kubungabunga ingufu.
Nyuma yo kuyungurura ibikorwa bimaze gushyirwa mubikorwa, bizamura cyane ubwiza bwumuriro wibitaro byibitaro, bikuraho ingaruka zumutekano, bitezimbere ingufu zamashanyarazi zifite umutekano kandi zisukuye kubikoresho byubuvuzi, kandi icyarimwe hitabwa kubika ingufu no kugabanya ibicuruzwa.
