Mataki na elektroniki da tattalin PLL na yin hanyar da zan iya ƙare da abu a matsayin karamin jiragen lashe-jiragen gajeren kashi

      A cikin littattafan da na faruwa wanda ake kira flexible power distribution unit, an yi a takaice wannan makarantar. An samun shaida daga hanyoyin gida zuwa hanyoyin lalace. An yi sabon misali 30 kW 600 VAC/220 VAC/110 VDC mai yawan wasa na tsakiyar wasa. A cikin littattafar, an bayyana hukumomin muhimman da za su iya amfani da su wajen ilimi na jihar gida, musamman idan akwai kisan wasa na gida. Da kuma, an yanayin mafi kyau game da masu sauki don in fahimtar masu sauki na three-phase PET da ke samun gida ta hanyar bincike mai yawa. An yanayi sabon misalin, kuma ya ba da ziyartar kisan wasa na gida. 

1.Makaranta.

     Wannan mutanen da aka fi sani da ita a jihar gida shine transformer, wanda yake da muhimmanci a cikin hanyoyin gida, kuma yana da alaka ga sunan hanyo da kuma babbar hanyo. Transformer na gida na da ingantaccen rarraba; amma, yana da kasa da kuma yawan kasa. Ba zan iya ba da kisan harmonics daga baya zuwa biyu, kuma ana bukata abubuwan kayan aiki don in tabbatar da ma kan damar gwaji. Yanzu, wasu nan suna da muhimmanci a cikin ilimin da kuma tattalin arziki. Saboda haka, transformer mai karfin ilimi, intelligent universal transformers, solid-state transformers, smart transformers, energy routers, da sauransu suna da muhimmanci a cikin ilimin da kuma tattalin arziki, musamman a cikin aerospace, railway traction, smart grid, da Energy Internet applications . Amfani da su a wurare da yaduwar kayan aiki da kuma yaduwar darasi suna da muhimmanci a cikin yadda ake samun su, musamman a wurare da yaduwar kasa da kuma yaduwar kasa .

2.Tashar da Karkashin PET.

    An yi amfani da yadda ake fitar da DC/DC converter mai yawan wasa na tsakiya, tare da hukumomin fitar da tsari mai yawan wasa. Ana kiran wannan kamar DC transformer, kuma yana ba da hanyo mai yawan wasa. Idan ake ci gaba da abubuwan hukumomi da kuma yadda ake kafa hanyoyin gida, yana iya samun yaduwar darasi da kuma yaduwar kayan aiki masu yawa cewa yana da filter choke ba ce.Three-phase inverters suna da uku na modular single-phase full-bridge H4 inverters, wanda suka da yaduwar jirgin hankali masu yawa, ko kuma za a iya samun hukumomin baya zuwa biyu don in tabbatar da su. Hanyoyin gida suka amfani da double-loop controllers, inda loop na biyu yana da alaka ga hanyar RMS value na hanyo, har da loop na uku yana da alaka ga hanyar instantaneous value na hanyo. Kuma, SPWM control strategy mai biyu yana taimaka wajen tabbatar da reactive power.

3.Hukumomin Muhimman Don In Tabbatar Da Voltage-Disturbance Ride Through.

     Idan ake amfani da PET a cikin kisan wasa na gida, observability da controllability suna da muhimmanci. Ingantaccen da kuma yawan tabbacin frequency da phase angle na wasa na gida suna da muhimmanci don in ba da reference signals masu yawa da kuma in taimaka wa utility codes, musamman a cikin kisan harmonics, voltage sags, frequency variations, da kuma phase jumps [21]. Yana da kyau a duba yadda ake canza wasa na gida don hukumomin baya. Saboda haka, an samun hukumomin biyu don PET, wanda suka bayyana a cikin littattafar, tare da PLL design methods, control principles, da kuma small-signal model na three-phase PWM rectifier. An yanayin mafi kyau game da masu sauki na three-phase PET da ke samun gida.

4.Kalmomin Littattafar.

        A cikin littattafar, an yi amfani da sabon PET da ke kiran flexible power distribution unit. DC/DC isolation don three-phase inverters an yi amfani da multiwinding transformer mai yawan kasa, wanda yana ci gaba da yaduwar kayan aiki. A cikin littattafar, an bayyana hukumomin muhimman game da grid code issues na PET, kamar kisan wasa na gida da kuma harmonic resonance, wanda ba suka san ba. An bayyana PLL design methods, control principles, small-signal model, da kuma input admittance na three-phase PWM rectifier. Wannan yana taimaka wajen fahimtar harmonic resonance a cikin power-electronics-based power systems da ke amfani da PET.
