Cov Xov Xwm Cua Hluav Taws Xob Hluav Taws Xob: Nrog rau kev txhim kho sai ntawm DC kis tau tus mob thev naus laus zis, nws txoj kev nyab xeeb, kev ruaj ntseg, thiab kev ua haujlwm tau ntsib cov teeb meem loj dua, tshwj xeeb tshaj yog cov hluav taws xob tsis zoo ntawm cov hluav taws xob tshiab nyob ib puag ncig ntawm DC kis tau tus mob tau dhau los ua qhov tseem ceeb ntawm kev mloog.
Txhawm rau txhim kho kev nyab xeeb thiab ruaj khov kev ua haujlwm ntawm cov phiaj xwm loj, cov teb chaws thoob ntiaj teb tau maj mam ua cov kev tshawb fawb txog qhov txhaum cai ntawm kev caij tsheb-los ntawm kev muaj peev xwm ntawm lub zog tshiab.Cov neeg tsav tsheb fais fab hauv ntau lub teb chaws, xws li Australian Energy Market Commission (AEMC) thiab US Tsoom Fwv Teb Chaws Kev Tswj Xyuas Hluav Taws Xob, tau ua kom pom tseeb cov cai rau kev caij tsheb loj-los ntawm kev muaj peev xwm ntawm cov khoom siv hluav taws xob tshiab raws li cov qauv kev lag luam loj. kab hluav taws xob.
1 Australia
Australia thawj zaug tsim cov lus qhia rau kev caij tsheb loj-los ntawm kev muaj peev xwm ntawm cua turbines nrog qhov tseem ceeb tiag tiag.Cov txheej txheem qhia tau hais tias thaum qhov hluav taws xob ntawm high-voltage sab kab sib chaws nce mus rau 130% ntawm qhov ntsuas hluav taws xob, cov cua turbines yuav tsum tau khaws cia rau 60ms yam tsis tau tawm ntawm kab sib chaws;Daim phiaj hluav taws xob sib txawv ntawm Thaum 130% ntawm tus nqi ntsuas rov qab mus rau 110% ntawm tus nqi ntsuas, chav tsev yuav tsum tau khiav mus rau 900ms yam tsis muaj kev cuam tshuam, thiab xyuas kom meej tias muaj qhov cuam tshuam txaus rov qab los txhawb qhov overvoltage txhaum.Daim duab 1 qhia txog Australian kev hnav khaub ncaws siab.
2 Teb Chaws Asmeskas
Daim phiaj sib txuas lus qhia rau cua turbines hauv Teb Chaws Asmeskas xav kom thaum daim phiaj hluav taws xob nyob rau sab high-voltage surges mus rau 120% ntawm qhov ntsuas hluav taws xob, cua turbine muaj peev xwm ua haujlwm tsis tu ncua rau 1 thib ob yam tsis tau tawm ntawm daim phiaj. ;thaum daim phiaj hluav taws xob nce mus txog 118%, cua turbine Nws muaj peev xwm ua haujlwm tsis tu ncua rau 2s yam tsis tau tawm ntawm daim phiaj;thaum daim phiaj hluav taws xob nce mus txog 115%, cua turbine muaj peev xwm ua haujlwm yam tsis tau tawm ntawm daim phiaj rau 3 vib nas this;Thaum lub high-voltage sab grid voltage swells mus rau 110% ntawm qhov ntsuas voltage, cua turbine muaj peev xwm ua hauj lwm tsis tu ncua yam tsis muaj disconnecting ntawm lub network.Daim duab 2 qhia txog US high-throughput grid-connected cov lus qhia.
3 Suav teb
Kuv lub teb chaws tseem nquag tsim cov qauv rau cua turbine siab voltage caij-los ntawm, thiab nyob rau hauv 2017 thiab 2018 raws li tau muab NB/T 31111-2017 "Cua Turbine High Voltage Caij Los Ntawm Kev Xeem Kev Cai" thiab GB / T 36995-2018 "Wind Turb "Cov txheej txheem xeem rau Fault Voltage Caij Los Ntawm Kev Muaj Peev Xwm", nws tus qauv Suav GB / T
Lub teb chaws tus qauv yuav tsum tau siv cov kev tiv thaiv-capacitance voltage divider high-throughput khoom rau cua turbine high voltage caij-los ntawm kev xeem.Daim duab 3 qhia txog schematic daim duab ntawm lub tshuab hluav taws xob boost.Kev tiv thaiv-capacitor voltage divider high-throughput Lub hauv paus ntsiab lus ntawm kev tiv thaiv-capacitance voltage division nce qhov voltage.
