Cov neeg siv khoom siv hluav taws xob paub qhov ntawdqhuav hom transformerskuj muaj lawv tus kheej tam sim no thiab voltages, thiab feem ntau, cov tam sim no thiab voltages yuav tsum muaj kev ruaj ntseg thiab ruaj khov.
Qee zaum, thaum lub tshuab ziab khaub ncaws ua haujlwm thiab kev ua haujlwm hnyav, yuav tsum xav txog seb qhov hluav taws xob ntawm lub tshuab ziab khaub ncaws qhuav yog qhov ruaj khov. Thaum tsis ruaj tsis khov, lawv yuav ua rau muaj qhov tsis zoo ntawm qhov hloov pauv qhuav thiab ua rau lub tshuab ziab khaub ncaws qhuav tawg, thiab lub tshuab ziab khaub ncaws qhuav tawg, qhov xwm txheej yog qhov txaus ntshai dua thiab qhov tshwm sim tsis tuaj yeem xav txog. Yog li ntawd, qhov tshwm sim ntawm voltage instability ntawm qhuav transformers yog loj, thiab hnub no peb yuav qhia txog qhov tshwm sim ntawm transformer instability.
Vim hais tias qhuav-hom transformers ua lub luag haujlwm tseem ceeb, yog tias muaj hluav taws xob tsis ruaj khov yuav muaj qhov tshwm sim loj, qhov tseeb, feem ntau muaj ob qhov teebmeem hauv qab no:
1. Thaum qhov hluav taws xob ntawm lub tshuab hluav taws xob qhuav tsis ruaj khov, yuav muaj qhov tsis sib npaug ntawm qhov tam sim no ob peb zaug siab dua li qhov qub tam sim no, thiab qhov kub ntawm qee qhov ntawm cov khoom siv hlau yuav nce siab, ua rau luv luv, thiab tuaj yeem ncaj qha. hlawv lub qhuav transformer. Nws nce tus nqi ntawm kev tswj cov khoom siv hluav taws xob thiab ua kom lub neej ua haujlwm ntawm cov khoom siv luv luv.
2. Nyob rau hauv ntau lawm thiab lub neej, qhov tsis ruaj tsis khov voltage ntawm qhuav-hom transformer ua rau peb ib leeg regulators khiav asymmetrical, uas ua rau ib tug nce nyob rau hauv qhuav transformer poob (tsis muaj-load poob thiab load poob).
Nws muaj kev cuam tshuam loj ntawm kab poob. Qhov voltage thiab tam sim no ntawm qhuav transformer tsis ruaj khov. Nyob rau ntawm lub sijhawm no, txawm tias qhov tam sim no raug faib mus rau ib qho kev hloov pauv qhuav li cas, qhov tsis sib npaug tam sim no yuav tsis sib npaug. Qhov loj dua qhov tsis sib npaug ntawm qhov tam sim no, qhov loj dua txoj kab poob.
