電壓波動(dòng)和閃變

    光伏電站接入電網(wǎng)后,在公共連接點(diǎn)處產(chǎn)生的電壓波動(dòng)和閃變應(yīng) 滿足 GB/T 12326-2008《電能質(zhì)量 電壓波動(dòng)和閃變》及《國(guó)家電網(wǎng) 公司光伏電站接入電網(wǎng)技術(shù)規(guī)定》的要求。由于天氣、云層、環(huán)境等 因素的影響,光伏電站可以看作一個(gè)具有一定隨機(jī)性的波動(dòng)負(fù)荷,電 壓波動(dòng)限值為 2%;對(duì)于較少發(fā)生的電壓波動(dòng)情況,電壓波動(dòng)限值可 參照頻度小于 1 次/h 的標(biāo)準(zhǔn)為 3%。

       根據(jù)逆變器 穩(wěn)態(tài)運(yùn)行時(shí),電壓波動(dòng)為 0.317%,小于電壓波動(dòng)限值為 2%;單臺(tái)逆 變器最大電壓波動(dòng)為 0.750%,小于電壓波動(dòng)限值為 3%,滿足 GB/T 12326-2008《電能質(zhì)量 電壓波動(dòng)和閃變》及《國(guó)家電網(wǎng)公司光伏電站接入電網(wǎng)技術(shù)規(guī)定》的規(guī)定要求。

      根據(jù)《國(guó)家電網(wǎng)公司光伏電站接入電網(wǎng)技術(shù)規(guī)定》的要求,光伏電站接入電網(wǎng)后,公共連接點(diǎn)短時(shí)間閃變 Pst 限值為 1.0,長(zhǎng)時(shí)間閃 變 Plt 限值為 0.8。光伏電站在公共連接點(diǎn)單獨(dú)引起的電壓閃變值應(yīng) 根據(jù)光伏電站安裝容量占供電容量的比例以及系統(tǒng)電壓,按照 GB/T 12326-2008《電能質(zhì)量 電壓波動(dòng)和閃變》的規(guī)定分別按三級(jí)作不同 的處理。

     江蘇芒種建設(shè)有限公司是一家專注于光伏領(lǐng)域的綜合能源服務(wù)商,致力于光伏電站投資、開(kāi)發(fā)、設(shè)計(jì)、建設(shè)、智能運(yùn)維、專業(yè)咨詢服務(wù)以及光伏電站設(shè)備回收的智慧能源企業(yè)。
