IiNdaba zoThungelwano lwaMandla omoya: Ngophuhliso olukhawulezayo lwetekhnoloji yothumelo lweDC, ukhuseleko lwayo, uzinzo, kunye nokusebenza kujongene nemiceli mngeni emikhulu, ngakumbi uxhathiso lombane ophakamileyo weyunithi zamandla amatsha kwindawo yokuhanjiswa kweDC iye yaba yingqwalasela.
Ukuze kuphuculwe indlela ekhuselekileyo nezinzileyo yokusebenza kweegridi zamandla amakhulu, amazwe ehlabathi ngokuthe ngcembe aqhube uphando ngempazamo yokukhwela kwamandla ombane asebenzisa amandla amatsha.Abaqhubi begridi yamandla aphambili kumazwe ahlukeneyo, anje ngeKhomishini yeMarike yezaMandla yase-Australia (AEMC) kunye neKhomishini yoLawulo lwaMandla oMmandla wase-US, benze iimfuno ezicacileyo zokukhwela kwamandla ombane aphezulu-ngokusebenzisa isakhono seseti yokuvelisa amandla amatsha ngokusekwe kubume bombutho omkhulu. iigridi zamandla.
1 eOstreliya
I-Australia yaqala yaqulunqa izikhokelo zokuhamba kwamandla ombane aphezulu okuhamba ngamandla kwiiinjini zomoya ngokubaluleka kokwenyani.Izikhokelo zichaza ukuba xa i-voltage yegridi yecala le-high-voltage inyuka ukuya kwi-130% yombane olinganisiweyo, ii-injini zomoya kufuneka zigcinwe kwi-60ms ngaphandle kokuphuma kwigridi;i-voltage yegridi iyahluka ukusuka Xa i-130% yexabiso elilinganisiweyo libuyela kwi-110% yexabiso elilinganisiweyo, iyunithi kufuneka iqhube i-900ms ngaphandle kokuphazamiseka, kwaye iqinisekise ukuba kukho okwaneleyo ukubuyiswa kwephutha ngoku ukuxhasa impazamo yokugqithisa.Umzobo we-1 ubonisa umgangatho wokugqoka ophezulu wase-Australia.
2 eUnited States
Izikhokelo eziqhagamshelwe kwigridi yeeinjini zomoya e-United States zifuna ukuba xa amandla ombane egridi kwicala le-voltage ephezulu enyuka aye kwi-120% yombane olinganisiweyo, i-injini yomoya inamandla okusebenza ngokuqhubekayo okomzuzwana omnye ngaphandle kokuphuma kwigridi. ;xa i-voltage yegridi iphakama ukuya kwi-118%, i-injini yomoya Inamandla okusebenza ngokuqhubekayo kwii-2 ngaphandle kokuphuma kwigridi;xa i-voltage yegridi iphakama ukuya kwi-115%, i-wind turbine inamandla okusebenza ngaphandle kokuphuma kwigridi imizuzwana emi-3;xa umbane wegridi yecala eliphezulu lombane udumba ukuya kwi-110% yombane olinganisiweyo, i-injini yomoya Inamandla okusebenza ngokuqhubekayo ngaphandle kokuqhawula kunxibelelwano.Umzobo we-2 ubonisa i-US ephezulu-throughput izikhokelo eziqhagamshelwe kwigridi.
3 China
ilizwe lam likwaqulunqa ngenkuthalo imigangatho yeinjini yomoya yokukhwela amandla ombane aphezulu, kwaye ngo-2017 kunye no-2018 ngokulandelelanayo ikhutshwe i-NB/T 31111-2017 “i-Wind Turbine High Voltage Ride through Test Regulations” kunye ne-GB/T 36995-2018 “Iijenereyitha zeTurbine yomoya ”Inkqubo yoVavanyo lweFault Voltage Ride through Capability”, umgangatho wayo waseTshayina we-GB/T
Umgangatho wesizwe ufuna ukusetyenziswa kwesixhobo sokuxhathisa amandla ombane esahluli samandla ombane aphezulu kwiinjini yomoya yovavanyo lokuhamba ngombane ophezulu.Umzobo 3 ubonisa umzobo weskimu sesixhobo sokunyusa amandla ombane.I-resistance-capacitor voltage divider high-throughput Umgaqo-siseko wokuchasana-i-capacitance ukwahlula i-voltage iphakamisa i-voltage.
