Ongororo pamusoro peTopology uye Mashandisirwo Ekutonga eMedium-High Voltage Power Electronic Transformers I

Nekukurudzirwa kwepfungwa yeinternet yesimba uye kushandiswa kwakapararira kwetekinoroji ine chekuita negrid yakangwara, huwandu hwesimba rinogona kudzokororwa senge simba remhepo nemagetsi aripo muhurongwa hwesimba huripo huchawedzera zvakanyanya. Izvi zvinoratidza kuti magrid emagetsi emangwana achava akangwara uye anochinjika. Muinternet yesimba, sezvo huwandu hwevashandisi vakagoverwa uye zviwanikwa zvesimba zvichikwira, kutapurirana kwemagetsi kunoda kugona kudzorwa zvakanyanya. Munetwork dzemagetsi dzakangwara, grid inofanira kuchengetedza simba rakasimba uye remhando yepamusoro uku ichibatanidza huwandu hwakawanda hwesimba rinogona kudzokororwa rakagoverwa uye mamiriro ekutarisa/kutarisira mashandiro egrid. Izvi zvinodiwa zvinoisa zvinodiwa zvakanyanya pahungwaru hwemidziyo yemagetsi, nepo ma transformer emagetsi echinyakare anotarisana nemiganho yekushanda.

MaPower Electronic Transformers (PETs), anoshandiswa kuburikidza nema power electronic conversion circuits ekushandura simba uye achishandisa ma medium-to-high-frequency transformers ekubatanidza nekubvisa ma magnetic, anomiririra mhinduro yepamusoro. Kana tichienzanisa nema power frequency transformers akajairika, ma PET anogonesa AC/DC energy conversion uye anobatanidza mabasa akadai se power factor correction, reactive power compensation, harmonic mitigation, uye relay protection nekuda kwe embedded power electronics dzavo. Nekuda kwekugona kwavo kudzora zvakanyanya, ma PET anoratidza mabhenefiti makuru ekushandisa mu energy internet uye smart distribution grid scenarios.
