Nazarin Kwatanta SVG da TSC na Gyaran Wutar Lantarki

Lokacin zabar kayan aiki, abokan ciniki suna buƙatar wuce kwatanta na’urori guda ɗaya kawai kuma suyi la’akari da ingantaccen tsarin wutar lantarki gaba ɗaya, tare da la’akari da mahimman abubuwa kamar buƙatun amsawa mai ƙarfi, yanayin harmonic, farashin aiki da kiyayewa na dogon lokaci, da ƙuntatawa na sarari. Duk da haka, a cikin aikace-aikace masu nauyin tasiri, ya kamata a ba da fifiko ga shigar da SVG (Static Var Generator).

I. Babban Fa’idodin SVG Idan aka Kwatanta da TSC

1. Amsa Mai Saurin Millisecond

SVG, bisa ga na’urorin wutar lantarki na IGBT, yana da lokacin amsawa <10ms, yana ba da damar bin diddigin canje-canjen lodi a ainihin lokaci (kamar tanderun wutar lantarki da nauyin tasirin injin mirgina).

TSC ya dogara da maɓallan inji (canjin contactor/thyristor), tare da saurin amsawa na 10-40 cycles (200ms-800ms), kuma ba zai iya hana saurin canjin wutar lantarki ba.

2. Ci Gaba da Rarraba Ba tare da Inrush Current ba

Ana iya daidaita girman/yanayin fitarwa na SVG daidai, yana samar da fitarwar wutar lantarki mai ci gaba da santsi.

TSC yana amfani da sauya capacitors a rukuni, yana haifar da yankin makaho na ramawa. Ana samar da inrush currents na 5-20 sau daidaitaccen wutar lantarki yayin sauya, yana barazana ga rayuwar kayan aiki.

3. Fitarwa Ba Ta Shafar Wutar Lantarki

SVG na iya fitar da daidaitaccen wutar lantarki capacitive/inductive (kamar topology na STATCOM) ko da a wutar lantarki ƙasa da 20%Un.

TSC fitarwar wutar lantarki mai amsawa ta yi daidai da murabba’in wutar lantarki (Q∝U²), kuma ƙarfin ramawa yana raguwa sosai a ƙananan wutar lantarki.

4. Ƙarfin Rarraba Biyu

SVG na iya samar da wutar lantarki mai amsawa capacitive (+Q) da inductive (-Q) a lokaci guda, yana magance matsalar wuce gona da iri a ƙarƙashin nauyi mara nauyi.

TSC yawanci yana fitar da wutar lantarki mai amsawa capacitive kawai, yana buƙatar ƙarin reactors don rama wutar lantarki inductive, yana ƙara rikitarwar tsarin.

5. Hana Flicker Wutar Lantarki da Harmonics

SVG na iya haɗa aikin tace wutar lantarki mai aiki (AHF), yana hana harmonics na musamman kamar 5th, 7th, da 11th yayin da yake rama wutar lantarki mai amsawa (misali, lokacin da aka haɗa da lodi na mai sauya mita).

TSC ba shi da ikon rage harmonics kuma yana iya ƙara harmonics (yana buƙatar saita reactors na detuning).

II. Muhimman Abubuwan La’akari don Zaɓin SVG

1. Lissafin Ƙarfi da Ƙarfin Wuce Gona da Iri

Zaɓin Ƙarfi: Dangane da matsakaicin rashi wutar lantarki mai amsawa tare da tazarar ramawa harmonic (ana ba da shawarar tazarar 20%). Misali, idan canje-canjen lodi ya haifar da buƙatar wutar lantarki mai amsawa ta 4 Mvar, ya kamata a zaɓi SVG na 5 Mvar.

Ƙarfin Wuce Gona da Iri: Mai da hankali kan 1.1 sau wuce gona da iri na dogon lokaci da 1.5 sau na ɗan gajeren lokaci (1 min) don magance tasirin wucin gadi.

2. Daidaitawa da Yanayin Grid

Matsayin Wutar Lantarki: Tabbatar da wutar lantarki na tsarin (misali, 6kV/10kV/35kV) da kuma izinin canji (±10%).

Asalin Harmonic: Idan THDv > 3% (misali, a masana’antar ƙarfe, masana’antar sinadarai), dole ne a zaɓi SVG tare da aikin hana harmonic, kuma dole ne a lissafta ƙarfin fitarwar harmonic.

3. Zane na Rage Zafi da Kariya

Hanyoyin Rage Zafi:

Ƙananan Ƙarfi (<2Mvar): Sanyaya Iska (IP41)

Matsakaici da Babban Ƙarfi (>2Mvar): Sanyaya Ruwa (IP54), ya dace da wuraren aiki masu ƙura

Zazzabi na Yanayi: Ana buƙatar rage ƙarfi sama da 40℃ (rage 1% ga kowane 1℃ ƙaruwa).

4. Dabaru na Sarrafawa da Ayyukan Kariya

Algorithm na Tsakiya: Zaɓi nau’ikan da ke amfani da ka’idar wutar lantarki mai amsawa nan take (hanyar p-q ko ip-iq) don tabbatar da daidaiton ramawa.

Muhimman Kariya: Kariya mai matakai da yawa daga wuce gona da iri na DC, wuce gona da iri na IGBT, da zafi mai yawa na radiator; MTBF (Matsakaicin Lokaci Tsakanin Kasawa) ya kamata ya zama >100,000 hours.

5. Aikace-aikacen Haɗaɗɗen Tare da TSC

Zane na Magani: Ana rama nauyin tushe ta TSC, yayin da SVG ke bin diddigin canje-canje (misali, tsarin ramawa na “TSC+SVG”), yana rage farashin gaba ɗaya.

Daidaitawar Sarrafawa: Ana samun sarrafawa ta haɗin gwiwa ta TSC/SVG ta hanyar kwamfuta mai ɗaukar hoto don guje wa jujjuyawar sauya.
