Izidingo kanye nokucaciswa kokuhamba kwamandla kagesi aphezulu ngobuchwepheshe bamaturbine omoya ekhaya naphesheya

I-Wind Power Network News: Ngokuthuthuka okusheshayo kobuchwepheshe bokudlulisa i-DC, ukuphepha kwayo, ukuzinza, nokusebenza kubhekene nezinselelo ezinkulu, ikakhulukazi ukumelana nomthamo ophezulu wamayunithi wamandla amasha endaweni yokudlulisa i-DC sekugxilwe kuyo.

Ukuze kuthuthukiswe ukusebenza okuphephile nokuzinzile kwamagridi amakhulu kagesi, amazwe emhlabeni jikelele kancane kancane enze ucwaningo mayelana nephutha lokuhamba kwamandla kagesi wamayunithi amasha wamandla.Abaqhubi begridi yamandla abahamba phambili emazweni ahlukahlukene, njenge-Australian Energy Market Commission (AEMC) kanye ne-US Federal Energy Management Commission, benze izidingo ezicacile zokugibela amandla kagesi aphezulu wamasethi amasha akhiqiza amandla asuselwa esakhiweni senhlangano esikhulu. amagridi amandla.

1 Australia

I-Australia yaqala ukwenza imihlahlandlela yekhono lokuhamba ngamandla kagesi aphezulu wamaturbine omoya ngokubaluleka kwangempela.Imihlahlandlela ibeka ukuthi lapho i-voltage yegridi eseceleni ye-voltage ephezulu ikhuphuka ifike ku-130% wevolthi elinganiselwe, izinjini zomoya kufanele zinakekelwe ama-60ms ngaphandle kokuphuma kugridi;amandla kagesi egridi ayahluka ukusuka kokuthi Lapho u-130% yenani elilinganiselwe libuyela ku-110% yenani elilinganiselwe, iyunithi idinga ukusebenza u-900ms ngaphandle kokuphazamiseka, futhi iqinisekise ukuthi kukhona okwanele kokuthola iphutha okwamanje ukusekela iphutha lokugcwala ngokweqile.Umfanekiso 1 ubonisa izinga lokugqoka eliphezulu lase-Australia.

2 United States

Imihlahlandlela exhunywe kugridi yezinjini zomoya e-United States idinga ukuthi lapho amandla kagesi egridi ohlangothini lwe-voltage ephezulu ekhuphuka aze afike ku-120% wevoltheji elinganisiwe, i-wind turbine inamandla okusebenza ngokuqhubekayo isekhondi elingu-1 ngaphandle kokuphuma kugridi. ;lapho i-voltage yegridi ikhuphukela ku-118%, i-turbine yomoya Inamandla okusebenza ngokuqhubekayo kuma-2 ngaphandle kokuphuma kugridi;lapho i-voltage yegridi ikhuphukela ku-115%, i-turbine yomoya inamandla okusebenza ngaphandle kokuphuma kugridi imizuzwana emi-3;lapho i-high-voltage side grid voltage ikhukhumala ukuya ku-110% we-voltage elinganiselwe, i-turbine yomoya Inamandla okusebenza ngokuqhubekayo ngaphandle kokunqamula kunethiwekhi.Umfanekiso 2 ubonisa imihlahlandlela exhunywe kugridi ye-US ephezulu.

3 China

Izwe lami futhi lisebenza ngokuzimisela ukwenza amazinga enjini yomoya yokugibela i-voltage ephezulu, futhi ngo-2017 kanye no-2018 ikhishwe ngokulandelana kwe-NB/T 31111-2017 “I-Wind Turbine High Voltage Ride Through Test Regulations” kanye ne-GB/T 36995-2018 “AmaGeneretha e-Wind Turbine ”Inqubo Yokuhlola Ye-Fault Voltage Ride Through Capability”, indinganiso yayo yesiShayina ye-GB/T

Izinga likazwelonke lidinga ukusetshenziswa kwe-resistance-capacitance voltage divider high-throughput okokusebenza kokuhlolwa kwe-wind turbine high voltage ride-through test.Umfanekiso 3 ubonisa umdwebo wohlelo lwedivayisi yokukhulisa amandla kagesi.I-resistance-capacitor voltage divider high-throughput Umgomo wokuhlukaniswa kwe-resistance-capacitance voltage ukhuphula i-voltage.
