並網風力發電機組中各種調節技術的特點

隨sui著zhe計ji算suan機ji技ji術shu和he先xian進jin控kong製zhi技ji術shu的de應ying用yong範fan圍wei逐zhu漸jian拓tuo寬kuan，並bing網wang風feng力li發fa電dian機ji的de控kong製zhi技ji術shu也ye發fa展zhan迅xun速su，其qi控kong製zhi方fang式shi也ye從cong基ji本ben的de單dan一yi定ding槳jiang距ju失shi速su控kong製zhi發fa展zhan到dao變bian槳jiang距ju變bian速su恒heng頻pin控kong製zhi

對dui於yu並bing網wang風feng力li發fa電dian機ji組zu，上shang述shu控kong製zhi技ji術shu各ge有you特te點dian，發fa揮hui的de作zuo用yong也ye不bu同tong。如ru果guo風feng力li發fa電dian機ji采cai用yong定ding槳jiang距ju失shi速su控kong製zhi技ji術shu，當dang實shi際ji風feng速su高gao於yu額e定ding風feng速su時shi

；當發電機的輸出功率達到額定功率時
，調節係統根據輸出功率的變化調整槳距角，使發電機的輸出功率保持在額定功率。
