SVG (Static Var Generator) na 10kV da take gano a tsakiyar hanyar kasa shi ne wani wurin cikakken abubuwan kompanshin kwasar kashi don jerin da tsakiyar kasa. An sanya "gano a tsakiyar hanyar kasa" a matsayin yadda ake gano wannan wurin a kan tsakiya 10kV tare da wasu wurin kasa, bai a yi buɗa ƙarin birnin kasa ba. Yana da muhimmanci a ci gaban samun kwalitoci da ingantaccen kasa. SVG na da fili mai lokaci na milliseconds, wanda ke iya bayyana kompanshin daga baya. A nan da ya zama current-source type, an yi aiki da ita a kan kwasar kashi kamar yadda ake amfani da shi, kuma yana iya bayyana kompanshin kwasar kashi ne daga baya a kan kwasar kashi. SVG na da mafi girman harmonics na biyu, kuma gano a tsakiyar hanyar kasa na iya kawo birnin kasa, wanda ke sa shi a haɗuwar.
Tsarin Sistemi da Muhimmancin Fanni
Jerin Tsari: Wurin Kasa: An sanya da kusan IGBT modules na 1700V-rated H-bridge da suka gano a tsakiyar hanyar kasa, suka taka ƙarin 10kV high voltage. An sanya da high-speed control (DSP+FPGA) a nan, kuma tana magana da duk wurin kasa tun daga RS-485/CAN bus don rike halittu da koyarwa. Transformer na Kasa: Yana da muhimmanci a ci gaban tsakiyar kasa, kafin kula, da kuma kawo ƙaramin kula.
Muhimmancin Fanni:An yi rike lamarin kasa daga baya, tana kula da kiyasin kompanshin kwasar kashi da za a iya buɗe, kuma tana kontrola IGBTs tun daga PWM technology. Wannan tana kawo ƙaramin kula da take gano a tsakiyar kasa da kuma phase-shifted da 90 degrees, tare da kiyashe kula da za a iya buɗe kwasar kashi. Saboda haka, a nan an yi amfani da active power ne kawai, wanda ke iya haɗa masu kasa da kuma kalmomin kasa.

Abubuwan Duk Da Mu
Karkashin da Kadan: Ba a yi buɗa transformer losses, ma'anar sistemi ya kai 98.5%, kuma tana kawo kudin transformer da kuma yanayin.
Ingantaccen da Kadan: Lokacin fili na milliseconds, kompanshin da ba ake kala, tana iya kawo kudin voltage flicker da take gano a kan impact loads (misali, arc furnaces, rolling mills).
Inganta da Karkashin: Yana iya bayyana kompanshin kwasar kashi ne daga baya idan kwasar kasa ya kusa.
Zane da Turawa: Tana da mafi girman harmonics, wanda ke iya kawo kudin pollution a kan grid.
