I. Bayanin Fannin Kudanci na Regulatorai na Kirkiyar Sistemar Jirgin Kuli

Idan kana bayyana fannin kudanci na regulatorai na kirkiyar sistemar jirgin kuli, yana da kyau a bayyana kudanci na regulatorai na shiga waɗanda ke taimaka da kuma kawo nasara daga mafi girma. A cikin amfani, regulatorai na shiga yake amfani da hanyoyi na kirkiya don kudanci, wanda yake haɗa kirkiyar gari na jirgin kuli a kan tsarin masu sahihi. Amma wannan nau'i na regulatorai na kirkiya, hasashen lokacin da take da abin da ba daidai, yana buƙata masu karfi a kan karfi da zai iya tabbatar da kirkiyar jirgin kuli da kuma sahihin sistema ta jirgin kuli. Saboda hakan, ya kamata a yi takamarta a cikin regulatorai na kirkiya. Masu ilimi sun nuna cewa tare da a gina kirkiyar jirgin kuli, gari na jirgin kuli da kuma regulatorai na shiga zai haɗa kudanci gari na jirgin kuli, kuma gari na jirgin kuli za a kawo taimaka a kan hanyoyin taimakawa wanda yake haɗa karfin masu karfi na jirgin kuli, kuma yana taimaka a taimakawa karfin masu karfi na jirgin kuli. Fannin kudanci na regulatorai na kirkiyar sistemar jirgin kuli shine kudanci gari na jirgin kuli tare da a gina kirkiya da kuma kirkiya na shiga. Idan yanayin gari na jirgin kuli yana ci, regulatorai na kirkiyar jirgin kuli yake rage muhimmiyar shiga da kuma kirkiya na shiga don tabbatar da kirkiya, kuma yana taimaka a taimakawa tabbas da rayuwar gwamnati na jirgin kuli.

A cikin amfani, regulatorai na kirkiyar sistemar jirgin kuli ana da muhimman abubuwa kamar busin kirkiyar masu karfi, setpoint na kirkiyar gari na jirgin kuli, amplification factor, phase compensation, output limiting, da on/off control. Lokacin da ake faɗa ko kofa regulatorai na kirkiyar sistemar jirgin kuli, babu wahala a kan kudancin regulatorai ko gari na jirgin kuli. A cikin tsari masu karfi, regulatorai na kirkiyar sistemar jirgin kuli yana iya rage resistance da reactance na gari na jirgin kuli zuwa batu; rarrabe rage yana bambanta da ratio na setpoint na kirkiyar gari na jirgin kuli, amma a cikin yadda ake gano, babu wahala a kan droop coefficient da power droop coefficient.

Amma don sake rage abin da ba daidai lokacin da ake kofa regulatorai na kirkiyar jirgin kuli na biyu, gari na jirgin kuli da suka shiga da kafin kofa yana da kyau a bayyana da droop rate, kuma yana da kyau a duba reactance da resistance na gari na jirgin kuli. Idan reactance da resistance na gari na jirgin kuli na regulatorai na kirkiyar jirgin kuli yana rage, reactance da resistance na gari na jirgin kuli ba suka shiga da kafin kofa yana da batu. Idan unit yana amfani da droop rate, yana da kyau a rage masu karfi na jirgin kuli da kuma taimaka na gari na shiga don kirkiyar jirgin kuli. Amma taimaka masu karfi na jirgin kuli a cikin hakan har yanzu yana da abubuwa masu gaskiya.

II. Bayanin Tattaunawa na Regulatorai na Kirkiyar Sistemar Jirgin Kuli

A cikin amfani na regulatorai na kirkiyar sistemar jirgin kuli, musamman idan mutum an samu gari na jirgin kuli da shiga da system ta infinite bus tare da double-circuit line, yana da yiwuwa cewa zai faru short circuit a cikin circuit. Idan short circuit yana faru, kirkiyar gari na jirgin kuli da kuma electromagnetic power zai rage. Tare da prime mover power wanda ba a yi kudanci, rotor yana buƙata a ci, kuma masu karfi na jirgin kuli ne yana da kyau zai rage, kuma yana taimaka a rage tabbacin kirkiyar sistemar jirgin kuli.

Sistemai na shiga na gari na jirgin kuli da suka fi sani ba su iya kudanci kirkiya da ma'ana. A cikin haka, kudancin kirkiyar high-voltage side, saboda hanyoyin da ke taimaka da system, yana buƙata a rage kirkiya zuwa batu lokacin da abin da ba daidai yana faru, kuma yana buƙata a kawo nasara daga mafi girma. Ba da short-circuit fault, kirkiyar gari na jirgin kuli da kuma kirkiyar high-side na gari na jirgin kuli yana rage zuwa batu zuwa mafi girma, kuma yana taimaka a tabbatar da kirkiya a kan batu zuwa mafi girma, kuma yana taimaka a taimakawa tabbas da kirkiyar bus.

Don in taimaka regulatorai na kirkiyar sistemar jirgin kuli a yi aiki da ma'ana, yana da kyau a yi hisabinta a cikin system. A cikin hisabinta, yana da kyau a bayyana matsaloli na excitation control mode a kan critical clearing time tare da systems masu karfi da kuma systems masu amfani. Idan a yi hisabinta single-machine infinite bus system, yana da kyau a bayyana structure ta infinite bus, dynamic model na gari, impedance na transformer, da kuma impedance na two-circuit transformer power system voltage regulator (Principles and Experimental Analysis, Zheng Changquan, Guangzhou Baiyun Electric Equipment Co., Ltd.). Daga baya, yana da kyau a bayyana short circuit na sistemar jirgin kuli, kuma yana da kyau a samun abubuwan da aka samu tare da simulation calculations. Abubuwan da aka samu sun nuna cewa regulatorai na shiga da kuma regulatorai na kirkiyar sistemar jirgin kuli ba su iya kudanci critical clearing time da ma'ana.

Idan a yi hisabinta system ta amfani, yana da kyau a amfani network ta amfani na grid structure ta power grid company, kuma yana da kyau a bayyana generator ta amfani na power plant. Daga baya, yana da kyau a bayyana short-circuit fault na sistemar jirgin kuli. Abubuwan da aka samu sun nuna cewa idan critical clearing time yana da standard value, regulatorai na kirkiyar sistemar jirgin kuli ba su iya kudanci da ma'ana lokacin da abin da ba daidai yana faru.

Don in taimaka a yi bayanin regulatorai na kirkiyar sistemar jirgin kuli da ma'ana, yana da kyau a shiga gari na jirgin kuli da shiga da system ta grid tare da single line, kuma yana da kyau a faɗa switch na high-side na gari na jirgin kuli (hakan yana da kyau a taimaka line switch yana da batu), kuma yana da kyau a zaɓe amplification factors da dama, kuma yana da kyau a bayyana system na excitation control tare da no-load voltage step response simulation calculation method. Abubuwan da aka samu sun nuna cewa idan amplification factor yana da batu, sistemar jirgin kuli yana da wahala na no-load stability. Don in taimaka a rage hakan, yana da kyau a amfani method na high-voltage bus control function a cikin no-load test.

Regulatorai na kirkiyar sistemar jirgin kuli yana da kyau a bayyana a cikin bus daɗinsu. A cikin bayanin tattaunawa, yana da kyau a taimaka a rage masu karfi na reactive power distribution a cikin generators masu shiga. A cikin amfani, yana da kyau a yi kudanci masu karfi na same power system voltage don in taimaka a taimakawa positive droop daɗinsu. A cikin amfani na power plant, yana da kyau a amfani simulation calculations don in taimaka a haɗa original excitation regulator da regulatorai na kirkiyar sistemar jirgin kuli, kuma suka taimaka a taimakawa reactive power deficit na sistemar jirgin kuli. Abubuwan da aka samu sun nuna cewa ba a yi competition na power lokacin da units suka yi aiki, kuma reactive power distribution yana da ma'ana daɗinsu.
