、慣性轉動：風(feng)力(li)發(fa)電(dian)機(ji)在(zai)受(shou)到(dao)風(feng)力(li)作(zuo)用(yong)後(hou)，由(you)於(yu)其(qi)較(jiao)大(da)的(de)轉(zhuan)動(dong)慣(guan)量(liang)，可(ke)能(neng)會(hui)在(zai)風(feng)力(li)減(jian)弱(ruo)或(huo)消(xiao)失(shi)後(hou)繼(ji)續(xu)轉(zhuan)動(dong)一(yi)段(duan)時(shi)間(jian)。這(zhe)是(shi)由(you)於(yu)機(ji)械(xie)係(xi)統(tong)本(ben)身(shen)的(de)慣(guan)性(xing)所(suo)導(dao)致(zhi)的(de)。

2、啟動轉矩：風feng力li發fa電dian機ji在zai設she計ji時shi會hui考kao慮lv到dao啟qi動dong轉zhuan矩ju的de問wen題ti，即ji在zai沒mei有you足zu夠gou風feng力li的de情qing況kuang下xia，如ru何he使shi發fa電dian機ji開kai始shi轉zhuan動dong。一yi些xie風feng力li發fa電dian機ji可ke能neng會hui采cai用yong特te殊shu的de啟qi動dong機ji構gou或huo控kong製zhi策ce略lve，如ru電dian動dong啟qi動dong或huo利li用yong其qi他ta能neng源yuan（如太陽能）來輔助啟動。

3、控製係統調節：現代風力發電機通常配備有先進的控製係統，這些係統可以根據風速、fengxiangheqitahuanjingyinsulaitiaojiefadianjideyunxing。zaimouxieqingkuangxia，kongzhixitongkenenghuizhudongtiaozhengfadianjidezhuansu，yiyouhuaqifadianxiaolvhuomanzudianwangdexuqiu。

需xu要yao指zhi出chu的de是shi
，盡jin管guan存cun在zai上shang述shu可ke能neng性xing，但dan在zai正zheng常chang情qing況kuang下xia，風feng力li發fa電dian機ji在zai沒mei有you風feng力li的de情qing況kuang下xia是shi不bu會hui轉zhuan動dong的de。因yin為wei風feng力li發fa電dian機ji的de轉zhuan動dong完wan全quan依yi賴lai於yu風feng力li來lai驅qu動dong

，沒mei有you風feng力li就jiu沒mei有you動dong力li來lai源yuan。此ci外wai，根gen據ju風feng力li發fa電dian機ji的de設she計ji原yuan理li和he技ji術shu參can數shu（如啟動風速、額定風速等），風feng力li發fa電dian機ji在zai風feng速su低di於yu一yi定ding閾yu值zhi時shi也ye無wu法fa啟qi動dong或huo維wei持chi轉zhuan動dong。因yin此ci，如ru果guo觀guan察cha到dao風feng力li發fa電dian機ji在zai沒mei有you風feng力li的de情qing況kuang下xia仍reng在zai轉zhuan動dong，那na麼me很hen可ke能neng是shi由you於yu某mou種zhong特te殊shu情qing況kuang或huo故gu障zhang所suo導dao致zhi的de。
