Isibuyekezo mayelana ne-Topology kanye ne-Control Applications ze-Medium-High Voltage Power Electronic Transformers I

Ngesiphakamiso somqondo we-inthanethi yamandla kanye nokusetshenziswa kabanzi kobuchwepheshe obuhlobene negridi ehlakaniphile, isilinganiso semithombo yamandla avuselelekayo njengamandla omoya kanye ne-photovoltaic ohlelweni lwamandla olukhona luzokhula kakhulu. Lokhu kubonisa ukuthi amagridi kagesi esikhathi esizayo azoba ahlakaniphile futhi aguquguquke. Ku-inthanethi yamandla, njengoba isilinganiso sabasebenzisi abasatshalaliswe kanye nezinsiza zamandla sikhuphuka, ukudluliswa kukagesi kudinga amakhono alawulekayo kakhulu. Kumanethiwekhi okusabalalisa ahlakaniphile, igridi kumele igcine ukuphakelwa kukagesi okuzinzile kakhulu futhi okuseqophelweni eliphezulu ngenkathi ihlanganisa ngokufanele inani elikhulu lemithombo yamandla avuselelekayo asatshalaliswe kanye nokuqapha/ukuphatha izimo zokusebenza kwegridi. Lezi zidingo zibeka izidingo eziqinile ekuhlakanipheni kwemishini yegridi yamandla, kuyilapho ama-transformer emvamisa yamandla endabuko ebhekene nemikhawulo yokusebenza ngokwemvelo.

Ama-Power Electronic Transformers (ama-PET), asetshenziswa ngamasekethe okuguqulwa kwamandla kagesi ukuze kuguqulwe amandla futhi asebenzisa ama-transformer aphakathi kuya kwaphezulu ukuze kuhlanganiswe futhi kusongwe amandla, amelela ikhambi elithuthukisiwe. Uma kuqhathaniswa nama-transformer avamile e-power frequency, ama-PET avumela ukuguqulwa kwamandla e-AC/DC futhi ahlanganise imisebenzi efana nokulungiswa kwamandla, isinxephezelo samandla esisebenzayo, ukunciphisa i-harmonic, kanye nokuvikelwa kokudluliselwa ngenxa yama-electronics awo afakiwe. Ngenxa yokulawula kwawo okuphezulu, ama-PET abonisa izinzuzo ezibalulekile zohlelo lokusebenza ku-inthanethi yamandla kanye nezimo zegridi yokusabalalisa ehlakaniphile.
