3.并網(wǎng)計(jì)算。當(dāng)風(fēng)電場(chǎng)平均風(fēng)速大于風(fēng)力發(fā)電機(jī)組的啟動(dòng)風(fēng)速時(shí)，風(fēng)機(jī)便開始轉(zhuǎn)動(dòng)，轉(zhuǎn)速不斷升高。當(dāng)轉(zhuǎn)速接近同步轉(zhuǎn)速時(shí)，風(fēng)電機(jī)組并入電網(wǎng)運(yùn)行。某系統(tǒng)接線3，2驟降，3HXD1638-170 單臺(tái)機(jī)組并網(wǎng)則對(duì)電網(wǎng)電壓的沖擊較小，且并網(wǎng)過程至少到3，8以后才基本消失，56.計(jì)算和分析明，并網(wǎng)時(shí)風(fēng)電場(chǎng)機(jī)端若能提供瞬時(shí)無功，則對(duì)地方電網(wǎng)的沖擊將大大減輕。7中的計(jì)算結(jié)果是有機(jī)端150131無功補(bǔ)償和沖擊無功補(bǔ)償時(shí)的情況。因?yàn)榇藭r(shí)。從系統(tǒng)注入風(fēng)電場(chǎng)異步電機(jī)的啟動(dòng)屯流大大減小，僅約為原來的0.

電叫電壓的這種突膃將人大影響風(fēng)電場(chǎng)剛近的供電質(zhì)量。
3HXD1638-170 講獻(xiàn)出，資每臺(tái)機(jī)端補(bǔ)償電容為5013作每臺(tái)機(jī)端補(bǔ)償電容為2001 3結(jié)論。風(fēng)電場(chǎng)注入系統(tǒng)功率較大時(shí)，風(fēng)電場(chǎng)母線及附近地區(qū)的電網(wǎng)電壓升高。尤其當(dāng)風(fēng)電場(chǎng)與系統(tǒng)間等值阻抗數(shù)值較大時(shí)，電壓升高極為嚴(yán)重多臺(tái)風(fēng)力發(fā)電機(jī)組的并網(wǎng)需分組進(jìn)行，且間隔時(shí)間不應(yīng)小于3，8，否則可能引起10以上的電壓驟降。適當(dāng)?shù)臎_擊電容補(bǔ)償可以減小多臺(tái)風(fēng)力發(fā)電機(jī)并網(wǎng)時(shí)的電壓降低。
3HXD1638-170 綜上所述，大型風(fēng)電場(chǎng)及附近地區(qū)的電壓存在波動(dòng)變化大的特點(diǎn)，必須予以高度重視。在今后的設(shè)計(jì)和運(yùn)行過程中應(yīng)采取措施，努力提高供電質(zhì)量。
