國(guo)家標準委員會日(ri)前正(zheng)式發布(bu)批準《風電(dian)(dian)場接(jie)入電(dian)(dian)力系統(tong)技(ji)術規定》的公告，這意味著(zhu)一項(xiang)新(xin)的風電(dian)(dian)并網(wang)技(ji)術標準出臺。

據(ju)悉，該標(biao)準由電(dian)監(jian)會主管的(de)全國電(dian)力(li)監(jian)管標(biao)準化技(ji)術委員會組(zu)織中(zhong)國電(dian)科院、電(dian)力(li)規(gui)(gui)劃設計總院等單位(wei)編(bian)制，規(gui)(gui)定(ding)風(feng)電(dian)場并網(wang)的(de)通用技(ji)術要(yao)(yao)求，并與能源行(xing)業標(biao)準《大(da)型風(feng)電(dian)場并網(wang)設計技(ji)術規(gui)(gui)范(fan)》共同(tong)規(gui)(gui)定(ding)了(le)風(feng)電(dian)場并網(wang)的(de)相(xiang)關技(ji)術要(yao)(yao)求。

這份被業(ye)內人(ren)士稱為“新國標”的風(feng)電(dian)(dian)并(bing)網(wang)(wang)新政可能會對(dui)處于低谷(gu)的風(feng)電(dian)(dian)產業(ye)帶來曙光，據悉，使風(feng)電(dian)(dian)業(ye)陷入(ru)“低谷(gu)”的一大原因(yin)(yin)是制造(zao)企業(ye)無(wu)法統一電(dian)(dian)網(wang)(wang)接入(ru)標準，因(yin)(yin)此引發多次風(feng)電(dian)(dian)脫網(wang)(wang)事故，造(zao)成安全供電(dian)(dian)的隱憂。

三(san)一電(dian)氣(qi)一位風(feng)(feng)機制(zhi)造工程師(shi)表示，這(zhe)項標(biao)準主(zhu)要針對風(feng)(feng)機的(de)低電(dian)壓(ya)穿越(yue)能(neng)力，這(zhe)項能(neng)力的(de)強(qiang)弱決(jue)定著尚“不(bu)穩定”的(de)風(feng)(feng)電(dian)能(neng)否擴大其上網(wang)比例，而不(bu)對電(dian)網(wang)造成威(wei)脅。

據該(gai)工(gong)程師介紹，所謂低(di)(di)電(dian)(dian)(dian)壓穿(chuan)越（LVRT）就是指在風力(li)(li)發電(dian)(dian)(dian)機并網(wang)點電(dian)(dian)(dian)壓跌落(luo)的(de)時(shi)(shi)候，風機能夠保持(chi)并網(wang)，甚至向(xiang)電(dian)(dian)(dian)網(wang)提供一定(ding)的(de)無功(gong)功(gong)率，支持(chi)電(dian)(dian)(dian)網(wang)恢(hui)復，直到(dao)電(dian)(dian)(dian)網(wang)恢(hui)復正常，從而“穿(chuan)越”這個低(di)(di)電(dian)(dian)(dian)壓時(shi)(shi)間。“這不僅要求風力(li)(li)發電(dian)(dian)(dian)系(xi)統(tong)具有較強(qiang)的(de)低(di)(di)電(dian)(dian)(dian)壓穿(chuan)越能力(li)(li)，同時(shi)(shi)能方便地為(wei)電(dian)(dian)(dian)網(wang)提供無功(gong)功(gong)率支持(chi)。”

要對風機(ji)(ji)進行低(di)電(dian)壓穿越能力改造(zao)，將(jiang)主要涉(she)及動態無功補(bu)(bu)償、變流(liu)器、控(kong)制器等設備的(de)改造(zao)，相關市場分析人士認(ren)為，這(zhe)將(jiang)給動態無功補(bu)(bu)償市場帶來一(yi)定機(ji)(ji)會。

湘財證券的分(fen)析師認為，動(dong)態(tai)無(wu)功(gong)補償裝(zhuang)置是柔性輸電(dian)(dian)(dian)系統(tong)的核(he)心，能快速有效調(diao)節(jie)電(dian)(dian)(dian)網(wang)的無(wu)功(gong)功(gong)率，抑(yi)制電(dian)(dian)(dian)壓波(bo)動(dong)和(he)閃變，使(shi)整個電(dian)(dian)(dian)網(wang)負荷的潮流分(fen)配更趨合理，改善電(dian)(dian)(dian)網(wang)質量(liang)，隨著國網(wang)公司和(he)南(nan)網(wang)公司對特(te)高壓輸電(dian)(dian)(dian)線(xian)路投(tou)資的加速，以及風電(dian)(dian)(dian)、光伏等間歇式能源并(bing)網(wang)需求的增加，未來動(dong)態(tai)無(wu)功(gong)裝(zhuang)置市場(chang)前景廣(guang)闊。
