同相牵引变电所补偿优化方案研究 Abstract Withthedevelopmentofpowergridconstructionandtheincreasingdemandforelectricalenergy,thereactivepowercompensationprobleminthepowergridhasbecomeincreasinglyimportant.Inparticular,thephasetractioncompensationtechnologyusedinthepowergridcaneffectivelyimprovethepowerqualityandstabilityofthepowersystem.Thispapermainlyintroducesandanalyzesthecharacteristicsofthephasetractioncompensationtechnologyinthepowergrid,andstudiestheoptimizationschemeofthephasetractioncompensationtechnologyinthepowergridcompensationsystem. Keywords:phasetractioncompensation,powergrid,reactivepowercompensation Introduction Powergridsplayalargeroleintransmittingelectricalenergy,buttheyaresubjecttovariousfactorsthatleadtovoltagedrops,voltagespikes,andharmonicdistortions.Oneoftheimportantsolutionstotheseproblemsistoimprovethecompensationtechnologyofthepowergrid.Inrecentyears,theresearchonphasetractioncompensationtechnologyinthepowergridhasreceivedwidespreadattention,andhasbecomeanimportantsolutiontosolvethereactivepowercompensationprobleminthepowergrid. Thephasetractioncompensationtechnologyisaneffectivemethodbasedontheprincipleofsynchronouscompensation,andismainlyusedtoimprovethereactivepowercompensationofpowersystem.Thetraditionalreactivepowercompensationtechnologymainlyincludescapacitivereactivepowercompensationandinductivereactivepowercompensation.Thecapacitivereactivepowercompensationismainlyusedforvoltageregulation,andtheinductivereactivepowercompensationismainlyusedforreducingpowerlosses.However,thesetraditionalmethodscannoteffectivelysolvethereactivepowercompensationproblem,especiallyforhighvoltageandlargecapacitygrid. Inthiscontext,phasetractioncompensationhasbecomeanewcompensationmethodinthepowergrid.Thephasetractioncompensationcanadjustthevoltagelevelbyadjustingthephaseangleofthetractiontransformer,therebyimprovingthereactivepowercompensationofthepowergrid.Thephasetractioncompensationtechnologyhastheadvantageoffastresponsespeed,highreliability,andlowenergyconsumption,w
