Reguladawar Jirgin Kirkiya na Maimakon

Reguladawar jirgin kirkiya na maimakon (AVR) yana cikin wurin da ya fi sani don inganta matsayinta jirgin kirkiya. Yana gane jirgin kirkiya mai girma kuma yana baka shi a kan jirgin kirkiya mai dace. Girman jirgin kirkiya suna nuna ne domin mutanen adadin zai a cikin abokan sauran kwabo. Wannan girman jirgin kirkiya zai iya haifar da wurare a cikin abubuwan kwabo, ko kuma iya haifar da babban lafiya.

Don inganta wannan girman jirgin kirkiya, ana iya gina abubuwan ingantaccen jirgin kirkiya a wurare masu muhimmanci a cikin abokan sauran kwabo, kamar yanayin tashin kirkiya, yanayin samun kirkiya, da yanayin kafa. Duk da haka, ana iya gina reguladawar jirgin kirkiya a wurare masu muhimmanci a cikin abokan sauran kwabo don inganta girman jirgin kirkiya a cikin abokan sauran kwabo.

Ingantaccen Jirgin Kirkiya a Cikin Abokan Sauran Kwabo DC da AC

• Abokan Sauran Kwabo DC: A cikin abokan sauran kwabo DC, idan an yi amfani da yanayin kafa masu tsari, ana iya amfani da yanayin samun kirkiya masu yawan alama don inganta jirgin kirkiya. Amma, idan yanayin kafa su masu tsari, ana iya amfani da yanayin kafa booster don inganta jirgin kirkiya a cikin karshe kan yanayin kafa.

• Abokan Sauran Kwabo AC: A cikin abokan sauran kwabo AC, ingantaccen jirgin kirkiya zai iya gudana a kan hanyoyin da suka dace. Su kasance amfani da yanayin kafa booster, yanayin samun kirkiya induction, da yanayin condensers. Har hanyar yana da muhimmanci da za a zabi har zuwa muhimmin abokan sauran kwabo.

Prinsipin Ingantaccen Reguladawar Jirgin Kirkiya

Reguladawar jirgin kirkiya yana yi aiki a cikin prinsipin tabbatar da abu. Kafin kima, ana samun jirgin kirkiya ta hanyar yanayin potential transformer. Ana kuma gane wannan jirgin kirkiya ta hanyar yanayin rectifier da filter, kuma kuma ana gano shi da jirgin kirkiya reference. Farkon bayan jirgin kirkiya da jirgin kirkiya reference yana nuna ne error voltage. Wannan error voltage zai iya gane ta hanyar amplifier, kuma kuma zai iya gina shi a kan main exciter ko pilot exciter. Ta hanyar gane shi da amplified error voltage, reguladawar jirgin kirkiya yana inganta da kuma baka jirgin kirkiya ta hanyar yanayin samun kirkiya, don haka ya ba da tashizawa da abokan sauran kwabo mai dace.

Saboda haka, amplified error signals yana gina excitation ta hanyar main ko pilot exciter a cikin hanyar buck ko boost. Wannan yana inganta girman jirgin kirkiya. Ta hanyar gane exciter output, terminal voltage ta hanyar main alternator yana inganta da kuma baka.

Tattalin Amfani da Reguladawar Jirgin Kirkiya na Maimakon

Reguladawar jirgin kirkiya na maimakon (AVR) yana da muhimmanci masu:

• Ingantaccen Jirgin Kirkiya da Ingantaccen Tsarin Kwabo: Yana baka jirgin kirkiya a cikin abokan sauran kwabo a kan iyakan da suka dace, kuma yana ba da machine aiki a kan iyakan da ke dace stability boundary. Wannan yana ba da tashizawa da abokan sauran kwabo mai dace da kuma inganta girman jirgin kirkiya a cikin abokan sauran kwabo.

• Sharhin Reactive Load: Idan kowane alternators suna yi aiki a kan parallel, AVR yana da muhimmanci wajen sharhi reactive load a kan su. Wannan yana inganta performance ta hanyar alternators da suke yi aiki a kan parallel da kuma baka power factor ta hanyar abokan sauran kwabo.

• Ingantaccen Overvoltage: AVR yana da muhimmanci wajen haifar da overvoltages wanda suna nuna ne saboda load shedding na maimakon. Ta hanyar gane excitation, yana haifar da jirgin kirkiya mai yawa wanda zai iya haifar da abubuwan kwabo.

• Gane Excitation a Kan Fault Time: A cikin fault, AVR yana gane excitation ta hanyar abokan sauran kwabo. Wannan yana ba da maximum synchronizing power a kan clearance ta hanyar fault, wanda yake inganta recovery ta hanyar abokan sauran kwabo.

• Gane Excitation Don Yi Iye: Idan an samu karfin iye a cikin alternator, AVR yana gane excitation system. Yana baka alternator yana ba da jirgin kirkiya masu dace a cikin tsari masu iye. AVR yana yi wannan a hanyar gane exciter field, modification ta hanyar exciter output voltage da field current. Amma, a cikin girman jirgin kirkiya mai yawa, standard AVR ba zai iya gane da kyau.

Reguladawar Jirgin Kirkiya na Maimakon

Don samun tashizawa mai kyau, ana iya amfani da quick-acting voltage regulators ta hanyar overshooting-the-mark principle. A cikin wannan principle, idan load yana zama, excitation ta hanyar abokan sauran kwabo zai iya zama. Amma, kafin jirgin kirkiya yana ci abin da ke dace da increased excitation, regulator yana gane da kuma zama excitation a kan level da ke dace. Wannan overshoot-and-correct mechanism yana ba da adjustment ta hanyar jirgin kirkiya mai kyau, wanda yake inganta performance ta hanyar abokan sauran kwabo a cikin dynamic load changes.
