Harmonic Kusefa uye Reactive Simba Muripo
MV SVC yeKugadzirisa Flickelharmonic uye Dynamic Reactive Muripo Matambudziko
Yedu SVC inosanganisira marudzi matatu ekuzadzisa zvinodiwa nemaindasitiri akasiyana uye masaiti: MCR, TSC, uye TCR. Iyo MCR mhando SVC inotora yega yakasanganiswa DC yekunakidzwa uye inodzika magineti saturation yekushanda modhi, iyo isingangodzikisire zvakanyanya iyo inogadzirwa harmonics, asi zvakare ine yakaderera inoshanda kurasikirwa kwesimba uye nekukurumidza kupindura kumhanya. Nekuchinja iyo inokonzeresa kona ye thyristor muMCR yekukurudzira dhigirii, iyo saturation dhigirii remagineti flux mukati meiyo magineti control reactor inogona kuchinjwa, nekudaro ichichinja reactive simba kugona kubuda kweiyo magineti control reactor.
Iyo MCR mhando SVC ine yakanyanya kuvimbika, yekuchengetedza yemahara, uye hupenyu hwesevhisi isingasviki makore makumi maviri. Masisitimu akakosha akadai semagetsi enjanji traction magetsi ekupa network akapihwa pamberi pekugamuchirwa; Inokwanisa kushanda yakagadzikana uye yakavimbika mune chero hutsinye hwemagetsi grid inoshanda nharaunda (senge voltage waveform distortion, yakakura amplitude fluctuations, nezvimwewo); Inogona kushanda zvakananga mune chero voltage level yemagetsi grid (6-500kV), uye iri nyore kuisa (yakafanana neyakajairwa matransformer) uye debug; Iyo reactive simba muripo wesimba inogona kugadziridzwa zvisingaite kuti iwane yakanakisa muripo maitiro.
SVG yeDynamic Reactive Power Muripo
SVG seyakasimba reactive simba sosi, inoshandisa high-speed computing components seDSP/IGBT, yakasanganiswa neultra precision control zvirongwa, kuronda shanduko chaiyo-nguva mugridhi yazvino, uye kuwedzera kukosha kwePF ku0.99 mukati me15ms.
Kushandiswa kwakapararira kwehukuru husina mitsetse mitoro uye mitoro yemagetsi semagetsi emagetsi ekufambisa uye kugovera magridi uye vashandisi veindasitiri kwaunza matambudziko makuru emhando yemagetsi. SVG inogona kuvandudza zvakanyanya kunaka kwesimba panzvimbo yekubatanidza pakati pemitoro negedhi remagetsi eruzhinji, sekuvandudza simba remagetsi, kukunda kusaenzana kwezvikamu zvitatu, kubvisa kubhururuka kwemagetsi uye kushanduka kwemagetsi, uye kudzvanyirira kusvibiswa kweharmonic.
Iyo SVG dynamic reactive reactive power compensation mudziyo inogadzirwa nekambani yedu ine zvakanakira mukupindura kumhanya, yakagadzikana grid voltage, yakaderedzwa system kurasikirwa, yakawedzera kufambisa simba, yakagadziridzwa yenguva pfupi voltage muganho, yakaderedzwa harmonics, uye yakaderedzwa tsoka. Kambani yedu ine hukama hwepedyo hwedzidzo uye kubatana kwehunyanzvi neanozivikanwa masangano ekutsvagisa uye makambani emagetsi kumba nekune dzimwe nyika. Isu takagadzirira kushanda pamwe chete nevatengi vedu kuvandudza kunaka kwesimba regetsi remagetsi nehunyanzvi hwepamusoro uye zvigadzirwa zvemhando yepamusoro, uye kubatsira mukuchengetedza simba, kuderedza kushandiswa, uye kugadzirwa kwakachengeteka mumagetsi ekugadzira, kupa, uye kushandiswa kwezvikamu.
LV AHF Yekudzikisa Harmonics muMagetsi Network
Takatarisana nedambudziko rakakura rekusvibiswa kwesimba reharmonic, AHF ndicho chishandiso chinoshanda chekuvandudza kunaka kwesimba. AHF chishandiso chitsva chehunyanzvi chesimba reharmonic control yakagadziridzwa ichishandisa yemazuva ano magetsi emagetsi tekinoroji uye yedhijitari chiratidzo chekugadzirisa tekinoroji yakavakirwa pakumhanya-mhanya kweDSP kugadzirisa michina. AHF yakaenzana neharmonic current jenareta, iyo inoteedzera maharmonic components muharmonic current uye inogadzira harmonic currents ine yakaenzana amplitude uye yakatarisana phase.AHF ine mativi maviri: rairo yemazuva ano oparesheni yedunhu uye muripo wechizvarwa chechizvarwa chedunhu. Iyo yekuraira yazvino dhijitari yedunhu inoona iripo mudunhu munguva chaiyo, inoshandura iyo analog yazvino siginecha kuita chiratidzo chedhijitari, uye inoitumira kune yakakwirira-kumhanya yedhijitari processor (DSP) yechiratidzo chekugadzirisa. Iyo harmonic uye yakakosha mafungu anopatsanurwa kuti awane yekuraira ikozvino, iyo inozotumirwa kune muripo wemazuva ano chizvarwa chedunhu muchimiro che pulse wide modulation (PWM) chiratidzo kuburikidza neazvino tracking control circuit uye drive circuit. Iyo IGBT uye IPM mamodule emagetsi anofambiswa kuti abudise muripo wezvino neamplitude yakafanana uye yakatarisana ne polarity seharmonic current, iyo inobaiwa mugedhi remagetsi kuripa kana kudzima harmonic yazvino, kushingaira kubvisa simba harmonics, uye kuwana simba, nekukurumidza, uye kunyatsogadziriswa kwesimba harmonics.
