BAYANIN AIKI:

IS200EGDMH1AFG Module Mai Gano Ground Exciter ne wanda General Electric ya ƙera kuma ya tsara shi azaman ɓangare na EX2100 Series da aka yi amfani da shi a cikin GE Excitation Control Systems. Ana amfani da Module Gane Ground IS200EGDMH1 a cikin EX2100 Excitation Control. Ramin ninki biyu ne, allo mai tsayi biyu (6U) wanda ke hawa a cikin Exciter Power Backplane rack (EPBP). Mai gano ƙasan filin yana gano juriyar shekarun filin tsakanin kowane batu a cikin kewaya filin janareta zuwa ƙasa, ko dai a gefen ac ko dc. Tsarin simplex zai sami EGDM guda ɗaya, kuma tsarin da ba shi da yawa zai sami uku. Ana nuna wurin EGDM(s) a cikin Hoto 1. EXAM, ma'aunin attenuator, yana jin ƙarfin lantarki a fadin ƙasa mai tsayayyar hankali kuma ya aika da siginar zuwa EGDM (s) akan kebul mai sarrafawa tara. Modulin EXAM an ɗora shi a cikin Module na Babban Wutar Lantarki da ke cikin Kwamitin Taimako.

A cikin ƙarin sarrafawa, saitin allunan EGDM guda uku an saita su azaman Mai sarrafawa (C), Jagora 1 (M1), da Jagora 2 (M2). Tsarin kowane EGDM ana sarrafa shi ta saitin fil ɗin shirin akan mai haɗin P2. Bayani game da abin da maigidan ya ba da siginar siginar zuwa ma'ana resistor a cikin Module Attenuator an aika daga DSPX, ta hanyar EISB a cikin rakiyar mai sarrafawa, zuwa EGDM C. Bayan karɓar wannan bayanin akan hanyar haɗin fiber-optic, C ko dai yana ba da iko a cikin Module Attenuator idan M2 shine direba, ko barin shi mara ƙarfi idan M1 shine zababben master. A lokaci guda kuma, ana aika sigina na banbanta zuwa M1 da M2 wanda ke nuna jagoran da aka zaɓa. Wannan siginar yana ba da damar janareta na sigina akan maigidan mai aiki kuma yana zaɓar tushen umarnin gwaji akan kowane module (M1, M2, da C). Yanzu mai aiki yana karɓar siginar Oscillator akan hanyar haɗin fiber optic daga DSPX ta hanyar EISB cewa yana canzawa zuwa siginar 50-volt mai kyau ko mara kyau. Ana aika wannan wutar lantarki mai murabba'i ta hanyar kebul zuwa ƙirar EXAM kuma ana amfani da ita zuwa ƙarshen Sense Resistor.

Sigina kwandishan yana karɓar sigina na banbanta (10:1) daga Sense Resistor a cikin tsarin EXAM. Na'urar kwandishan siginar siginar ƙararrawa ce mai sauƙi na haɗin kai tare da babban yanayin kin amincewa da yanayin gama gari wanda ke biye da mai sauya A-zuwa-D (Voltage Controlled Oscillator VCO). VCO tana ciyar da mai watsa fiber optic. Na'urar kwandishan na siginar tana aiki da keɓantaccen wutar lantarki don kiyaye lafiyar ma'aikata da kayan aiki saboda babban ƙarfin yanayin gama gari a Sense Resistor. Na'urar sanyaya sigina na iya auna matakin fitarwar ƙarar wutar lantarki ta hanyar saukar da gefen gada na madaidaicin Sense Resistor akan umarni daga sashin sarrafawa.

SIFFOFI:

• Sashen C na mai sarrafawa yana karɓar duk shirye-shirye da sigina na sarrafawa daga maɓuɓɓuka daban-daban don sanin wane nau'i ne zai zama maigidan. Hakanan yana karɓar siginar oscillator daga DSPX don ta iya samar da umarnin gwaji a kowane canji na siginar oscillator.

• Umurnin gwajin sigina ce mai tsayi 250 ms wanda za'a iya sake kunnawa akan kowane canji na siginar oscillator (ko da lokacin siginar bai wuce 250 ms ba).

• Ana aika wannan umarnin gwajin zuwa sashin sarrafawa na kowane nau'i (M1, M2, da C) don samar da siginar gwaji mai tsayi 250 ms a kowane ingantaccen canji na umarnin gwajin. Wannan siginar ba ta da ƙarfi don haka dole ne a raba canjin fiye da 250 ms kafin a iya haifar da wata siginar gwaji.

• Sashin samar da wutar lantarki yana karɓar 24 V dc daga EPSM mai dacewa ta hanyar EPBP (baya). Yin amfani da dc zuwa dc mai canzawa, yana jujjuya wannan zuwa ± 65 V dc (ba a ware) don haɓakar wutar lantarki a cikin sashin janareta na siginar, da + 5 V dc ( ware) da ± 15 V dc ( ware) don daidaitawar siginar.

• Fitowar amplifier wutar lantarki shine tushen ƙarfin lantarki tare da abin da aka fitar da ƙasa da 1.0 Ohm. Wutar lantarki mai fitarwa shine ± 50 Volt squarewave tare da iyakacin iyaka zuwa kusan 80 mA, kuma tare da lokacin aiki na yau da kullun na 5 seconds. Yayin aikin gwaji, lokacin yana rage zuwa 400 ms.
