Karkashin Kula Mai Yawan Ziyarar Turbin Da Duk'ar Turbin: Scott, Inverse Scott, da V-v Connections

1 Bayanin Dangantaka na Tattalin Sabis da Aikace-aikacen Yadda ake Tattara

QJ35 turn ratio bridge da wasu tattalin sabis na dukkan zafi sun amfani da shirin double-voltmeter. Amma QJ35 ya koyar da ci gaba da hankali ga abin da suka faruwa ne bayan cikakken gwamnati. Don tattalin sabis na tsarin mutane na turanci aiki da jirgin rike, yawanci za a fuskantar matasa da kuma yin taswirawa, inda zai yi taswirar tsarin mutane na biyu zuwa taswirar tsarin mutane na tafkin, kuma yin taswirar √3 Yd bayan da aka duba tsarin magana.

Masu tsarin kawo-kawo mai yawan alamar da sauran masu tsarin kawo-kawo suka samu nasarorin yawan aiki da wannan tattalin. Masu tsarin Scott suna da alamar cin kawo-kawo na farko, kuma masu tsarin rectifier suna da alamar cin kawo-kawo na biyu. Taswirar tsarin mutane na biyu ta hanyar fuskantar matasa ya koyar da alamar cin kawo-kawo, wanda ya haifar da sakamakon da ke nuna tsarin kawo-kawo, kuma bai iya tabbatar da alamar cin kawo-kawo na farko-biyu ba.

2 Tattalin Sabis na Tsarin Kawo-Kawo da Alamar Cin Kawkowon Masu Tsarin Kawo-Kawo Mai Yawan Alama

Don tattalar da tsarin kawo-kawo na masu tsarin kawo-kawo mai yawan alama (kamar da ake bayyana), ya kamata a amfani da jirgin rike na tsarin mutane na uku (120° farko da tsari, tsarin mutane) ko tsarin biyu (90° farko da tsari, don masu tsarin Scott). Abin da ya fi shi: tattala da karkashin aiki na masu tsarin kawo-kawo, amfani da ~110V, tattala da tsarin kawo-kawo na farko-biyu da kuma farkon tsari don nuna tsarin kawo-kawo da alamar cin kawo-kawo.

A Filin 2, (N,n) shine sabis na alamun sinyal. Amfani da tsarin rike na tsarin mutane na uku da tsari daidai domin tattalar da tsarin kawo-kawo na tsarin mutane na uku, tattala da tsarin kawo-kawo na tsarin mutane (U_A, U_B, U_C, U_a, U_b, U_c) da karkashin alamun sinyal. Amfani da operasun vector don tattalar da tsarin kawo-kawo na tsarin biyu (U_AB, U_BC, U_CA, U_ab, U_bc, U_ca). Nuna tsarin kawo-kawo (K_AB/_ab, K_BC/_bc, K_CA/_ca) kamar da aka bayyana, kuma nuna tsarin magana tun daga farkon UAB-Uab. Don masu tsarin Scott, amfani da tsarin rike na tsarin biyu da tsari 90° domin tattalar da tsarin kawo-kawo da kuma farkon tsari. Wannan tattalin ya koyar da tsarin magana na aiki da tsarin magana na tattalin, kuma ya tabbatar da abubuwan da aka nuna suna nufin tsarin kawo-kawo da alamar cin kawo-kawo na gaba-daya.

3 Tushen Tattalin Sabis

Wannan lokacin, saboda harsunan tushen masu inganci, karfin tushen jirgin rike, da kuma tushen tushen sinyalin digitalsu, ana iya kawo tattalin sabis mai yawan alama kamar da aka bayyana. Tattalin sabis ya koyar da waɗannan tsofaffi: jirgin rike, kogin sinyalin kadan da kusa, da kuma tushen sinyalin digitalsu.

Don tattalar da tsarin kawo-kawo na masu tsarin kawo-kawo mai yawan alama, ya kamata a amfani da jirgin rike na tsarin mutane na uku ko tsarin biyu da tsari 90°. Sinyalin da aka fara kan amfani a kan jirgin rike, kuma bayan an koyar da jirgin rike, ana fitar da jirgin rike na AC na tsarin mutane na uku, don haka tattalar da tsarin kawo-kawo na masu tsarin kawo-kawo mai yawan alama a kan aikinsu. Don koyar da tushen ci gaban jirgin rike (AC 220 V) na tattalin sabis, jirgin rike na tsarin da aka fitar da ya kamata a da tushen da take da yawa.

Saboda ana iya amfani da tushen vector da yawa, don tabbatar da alamar cin kawo-kawo da kuma farkon tsari na tsarin mutane na farko-biyu, ya kamata a kogin sadarwa da kusa, kuma ya kamata a kogin sadarwa na tsarin mutane na uku da kuma tsarin biyu. Tattalin sabis ya amfani da tushen single-chip microcomputer da FPGA. FPGA ya koyar da kogin sadarwa da kusa da kuma kogin data, kuma single-chip microcomputer ya koyar da tushen data da kuma fitar da data.

Don koyar da tushen ci gaban tushen electromagnetic interferences a filin tattalin, koyar da tushen ci gaban tushen sinyalin da ba sinyalin fundamental na AC ba, kuma amfani da tushen fast Fourier transform algorithm don tushen sinyalin digitalsu, don haka tattalar da tushen vector na sadarwa da kuma farkon tsari na tsarin mutane na farko-biyu, kuma tattalar da farkon tsari da alamar cin kawo-kawo.

Don koyar da tushen ci gaban tushen jirgin rike na tsarin mutane na uku a tattalin sabis, idan tsarin kawo-kawo na tsarin mutane na uku shine 80 V, tushen ci gaban jirgin rike na tsarin kawo-kawo ya kamata a da tushen da take da yawa, kuma tushen ci gaban tsari ya kamata a da tushen da take da yawa.

4 Abubuwan da aka Nuna don Masu Tsarin Scott da Inverse Scott

Tattalin sabis na masu tsarin kawo-kawo mai yawan alama da aka kawo kamar da aka bayyana ta koyar da tattalin a filin substation, kuma abubuwan da aka nuna su ne a Filin 1.

Daga Filin 1, ana iya nuna cewa tattalin sabis na masu tsarin kawo-kawo mai yawan alama ta koyar da tattalin tsarin kawo-kawo na masu tsarin kawo-kawo mai yawan alama, kuma farkon tsari ta koyar da tushen da aka nuna a filin masu tsarin kawo-kawo. Farkon tsari na Filin 1 suna nuna farkon tsari da aka bayyana, kuma an-bn shine farkon tsari na tsarin mutane na biyu.

5 Tattalin Masu Tsarin V-v Connected Transformers

Tsarin kawo-kawo da kuma diagram na tsarin kawo-kawo na masu tsarin V-v connected transformers suna da tushen da suka samu da masu tsarin Scott. Amma abin da suka da shi shine cewa suke koyar da jirgin rike na tsarin mutane na uku zuwa jirgin rike na tsarin biyu da tsari daidai don tabbatar da tushen ci gaban tushen loads. Saboda haka, za a iya amfani da tushen tattalin da aka bayyana. Filin 3 da 4 sun nuna diagram na tsarin kawo-kawo da kuma diagram na tsarin kawo-kawo na waɗannan tushen tsarin kawo-kawo.

Saboda farkon tsari na tsarin biyu na tsarin biyu a filin V-v connected mode shine 60°, ba 90° a filin Scott, abubuwan da aka nuna ta koyar da tushen da aka nuna a filin tushen relative error na tsarin kawo-kawo.

Idan ake tattala da BZJT-I tester, za a zabi "Scott" mode, kuma za a fuskantar switch don tattalin sabis.

Yana da kyau a nemi cewa tsarin kawo-kawo na standard na wannan shine tsarin kawo-kawo na tsarin kawo-kawo na tsarin mutane na uku zuwa tsarin kawo-kawo na tsarin mutane na biyu U_ab/U_αn ko U_ab/U_βn. A diagram, a da kuma b suna nuna α da β na masu tsarin Scott, kuma n shine terminal na masu tsarin α da β.

Filin 2 sun nuna abubuwan da aka nuna na masu tsarin Scott. Idan ake tattalar da tushen "AB/ab", tattalin sabis ya koyar da tushen input na tsarin kawo-kawo na standard zuwa 1.4142 domin tattalar da tushen benchmark. Don masu tsarin V-v connected, saboda farkon tsari na tsarin biyu na tsarin biyu shine 60°, ana iya amfani da tushen fixed difference na 41.42% domin tattalar da tushen relative error, amma tsarin kawo-kawo na actually measured value ya fi shi daidai.

Don masu tsarin V-v connected, ma'adantuka na farkon tsari ya kamata a da -60.000° (farkon tsari na tsarin kawo-kawo na tsarin biyu) da -300.00° (farkon tsari na tsarin kawo-kawo na tsarin biyu).

6 Kammal

Amfani da jirgin rike na tsarin mutane na biyu ba za a iya tabbatar da tushen tattalin sabis na tsarin kawo-kawo da alamar cin kawo-kawo na masu tsarin kawo-kawo mai yawan alama. Don tabbatar da tushen tattalin sabis na tsarin kawo-kawo na masu tsarin kawo-kawo mai yawan alama a filin site da kuma masu tsarin kawo-kawo, ya kamata a amfani da tushen jirgin rike na tsarin mutane na uku. Tattalin sabis na masu tsarin kawo-kawo mai yawan alama, da aka koyar da tushen output na jirgin rike na tsarin mutane na uku, da kuma tushen high-speed synchronous acquisition technology da kuma tushen digital signal processing technology, ya koyar da tushen tattalin sabis na tsarin kawo-kawo da alamar cin kawo-kawo na daidai.
