Wind Power Network News: Me ka hoʻomohala wikiwiki ʻana o ka ʻenehana hoʻoili DC, ʻo kona palekana, kūpaʻa, a me kāna hana ke kū nei i nā pilikia nui aʻe, ʻoi aku ka nui o ke kūpaʻa uila kiʻekiʻe o nā ʻāpana ikehu hou ma kahi kokoke i ka hoʻouna ʻana o DC ua lilo i mea nui o ka nānā.
I mea e hoʻomaikaʻi ai i ka hana palekana a me ka paʻa o nā mana mana nui, ua hana mālie nā ʻāina a puni ka honua i ka noiʻi e pili ana i ka hiki ke holo uila hewa o nā ʻāpana ikehu hou.ʻO nā alakaʻi alakaʻi mana mana ma nā ʻāina like ʻole, e like me ka Australian Energy Market Commission (AEMC) a me ka US Federal Energy Management Commission, ua hōʻike maopopo i nā koi no ka hiki ke holo uila kiʻekiʻe o nā pūnaehana uila hou e pili ana i ka hoʻonohonoho hoʻonohonoho o ka nui. pūnaewele mana.

Ua hoʻokumu mua ʻo Australia i nā alakaʻi no ka hiki ke holo uila kiʻekiʻe o nā turbines makani me ke koʻikoʻi maoli.'Ōlelo nā alakaʻi i ka wā e piʻi ai ka volta o kaʻaoʻao kiʻekiʻe-voltage i ka 130% o ka volta helu, pono e mālamaʻia nā makani makani no 60ms me ka heleʻole i waho o ka pūnaewele;ʻokoʻa ka uila uila mai ka 130% o ka waiwai i helu ʻia i ka 110% o ka waiwai i helu ʻia, pono e holo ka ʻāpana no 900ms me ka ʻole o ke keakea ʻana, a e hōʻoia i ka lawa o ka hoʻihoʻi hewa i kēia manawa e kākoʻo i ka hewa overvoltage.Hōʻike ka Figure 1 i ke kūlana lole kiʻekiʻe o Australia.
2 ʻAmelika Hui Pū ʻIa
ʻO nā alakaʻi pili pili pūnaewele no nā huila makani ma ʻAmelika Hui Pū ʻIa e koi aku i ka wā e piʻi ai ka uila uila ma ka ʻaoʻao kiʻekiʻe-voltage i ka 120% o ka volta helu helu, hiki i ka turbine makani ke hana mau no 1 kekona me ka ʻole e haʻalele i ka pā. ;i ka piʻi ʻana o ka voltage grid i 118%, ʻo ka turbine makani Hiki iā ia ke hana mau no 2s me ka hele ʻole o ka pā;i ka piʻi ʻana o ka voltage grid i 115%, hiki i ka turbine makani ke hana me ka ʻole o ka hele ʻana i waho o ka grid no 3 kekona;i ka wā e pehu ai ka uila ʻaoʻao kiʻekiʻe kiʻekiʻe i ka 110% o ka volta i helu ʻia, ua loaʻa i ka turbine makani ka hiki ke hana mau me ka wehe ʻole ʻana mai ka pūnaewele.Hōʻike ka Figure 2 i nā alakaʻi alakaʻi pili kiʻekiʻe o US.
3 Kina
ʻO koʻu ʻāina ke hana ikaika nei i nā kūlana no ka holo uila uila kiʻekiʻe, a ma 2017 a me 2018 i hoʻopuka ʻia NB / T 31111-2017 "Wind Turbine High Voltage Ride Through Test Regulations" a me GB / T 36995-2018 "Wind Turbine Generators "Ke kaʻina hana hoʻāʻo no ka holo ʻana o ka uila hewa ma o ka hiki", kāna maʻamau Kina GB/T
Pono ke kūlana aupuni i ka hoʻohana ʻana i nā mea hoʻokaʻawale uila resistance-capacitance divider kiʻekiʻe-throughput no nā hoʻāʻo holo uila kiʻekiʻe.Hōʻike ke kiʻi 3 i ke kiʻikuhi schematic o ka mea hoʻoulu uila.ʻO ka puʻupuʻu puʻupuʻu kū'ē-capacitor divider kiʻekiʻe-throughput ʻO ke kumu o ke kū'ē-capacitance puʻupuʻu puʻupuʻu hoʻokiʻekiʻe i ka uila.
