目前，風力發電的並網方式大致可分為異步發電機、同步發電機和雙饋發電機。

1、異步發電機直接並網

異步發電機直接並網是指當風驅動的異步發電機速度接近同步速度時，可自動並網；zidongbingwangxinhaoyousuduceliangzhuangzhitigong，ranhoutongguozidongkongqikaiguanwanchengbingwangguocheng。zhijiebingwangshi，youyufadianjisudujiejindanweiwanquantongbuyudianwangpinlv，jierushunshichongjidianliukedadianjiedingdianliude5至9倍bei，不bu僅jin影ying響xiang發fa電dian機ji本ben身shen的de安an全quan，而er且qie可ke能neng導dao致zhi電dian網wang電dian壓ya突tu然ran下xia降jiang，影ying響xiang電dian網wang的de穩wen定ding性xing和he安an全quan性xing。雖sui然ran這zhe種zhong並bing網wang方fang式shi很hen簡jian單dan
