Wind Power Network Nhau: Nekukurumidza kusimudzira kweDC tekinoroji yekufambisa, kuchengetedzeka kwayo, kugadzikana, uye kushanda kwakatarisana nematambudziko makuru, kunyanya kukwira kwemagetsi emagetsi emagetsi matsva ari pedyo neDC kutapurirana kwave kutarisisa.
Kuti uvandudze kushanda kwakachengeteka uye kwakagadzikana kwemagetsi makuru emagetsi, nyika dzepasirese zvishoma nezvishoma dzakaita tsvakiridzo pamusoro pekutadza kwevoltage ride-kuburikidza nekugona kwemasimba matsva.Vanotungamira magetsi emagetsi munyika dzakasiyana siyana, seAustralian Energy Market Commission (AEMC) uye US Federal Energy Management Commission, vaita zvakajeka zvinodiwa pakukwira kwemagetsi-kuburikidza nekugona kwemaseti matsva ejenareta zvinoenderana nehurongwa hwesangano hwehombe. magetsi emagetsi.
1 Australia
Australia yakatanga kugadzira nhungamiro dzekukwira kwevoltage-kuburikidza nekugona kwematurbine emhepo ane kukosha chaiko.Nhungamiro inotaura kuti kana magetsi emagetsi e-high-voltage side grid achikwira kusvika ku130% yemagetsi akarongwa, mavhiriji emhepo anofanira kuchengetedzwa kwe60ms pasina kubuda kunze kwegridi;iyo grid voltage inosiyana kubva Apo 130% yehuwandu hwehuwandu hunodzokera ku110% yehuwandu hwehuwandu, chikwata chinoda kumhanya kwe900ms pasina kukanganisa, uye chengetedza kuti pane zvakakwana kukanganisa kupora ikozvino kutsigira kukanganisa kwe overvoltage.Mufananidzo 1 unoratidza iyo yekuAustralia yakakwirira yekupfeka mwero.
2 United States
Giridhi-yakabatana nhungamiro yematurbine emhepo muUnited States inoda kuti kana giredhi regidhi padivi repamusoro-voltage richikwira kusvika pa120% yevoltage yakatemerwa, turbine yemhepo inokwanisa kuramba ichishanda kwesekondi 1 pasina kubuda gridhi. ;apo grid voltage inokwira kusvika 118%, mhepo yemhepo Iine simba rekushanda nguva dzose kwe2s pasina kubuda grid;apo grid voltage inokwira kusvika 115%, mhepo yemhepo ine simba rekushanda pasina kubuda grid kwemasekonzi matatu;kana high-voltage divi giredhi voltage kuzvimba kusvika 110% of rated voltage, mhepo turbine Kugona kushanda nguva dzose pasina disconnected kubva network.Mufananidzo 2 unoratidza iyo US yakakwirira-kuburikidza grid-yakabatana nhungamiro.
3 China
nyika yangu zvakare iri kushingaira kugadzira zviyero zvemhepo turbine yakakwira-voltage-kupfuura, uye muna 2017 uye 2018 zvakateerana yakapihwa NB/T 31111-2017 "Wind Turbine Yakakwira Voltage Ride Kuburikidza neMitemo Yekuyedza" uye GB/T 36995-2018 "Wind Turbine Generators. "Maitiro Ekuyedza YeFault Voltage Ride kubudikidza Nekugona", yayo yeChinese standard GB/T
Chiyero chenyika chinoda kushandiswa kwekupikisa-capacitance voltage divider high-throughput equipment ye wind turbine high voltage ride- through testes.Mufananidzo 3 unoratidza dhizaini yedhizaini yekuwedzera voltage.The resistance-capacitor voltage divider high-throughput Nheyo yekupikisa-capacitance voltage division inosimudza magetsi.
