國(guo)家(jia)電(dian)網承(cheng)接的首個百兆瓦(wa)級儲能(neng)(neng)電(dian)站(zhan)，采用(yong)智光級聯高(gao)壓(ya)儲能(neng)(neng)系(xi)統(tong)項(xiang)目由14套單機(ji)7.2MW/14.4MWh儲能(neng)(neng)系(xi)統(tong)構(gou)成，共(gong)42個儲能(neng)(neng)電(dian)池(chi)艙。 據測算，該儲能(neng)(neng)項(xiang)目每(mei)年最高(gao)可消(xiao)納電(dian)網清潔能(neng)(neng)源(yuan)7300萬(wan)千(qian)(qian)瓦(wa)時，在用(yong)電(dian)高(gao)峰期提供5900萬(wan)千(qian)(qian)...
項(xiang)目(mu)儲能(neng)系統(tong)總(zong)規模20MW/10MWh，由4臺5MW/2.5MWh級聯型(xing)高壓直掛式(shi)儲能(neng)裝置組成。 本項(xiang)目(mu)是廣東(dong)省能(neng)源集團積(ji)極參與儲能(neng)調(diao)頻的首批三個試點項(xiang)目(mu)之一。
該電池儲能(neng)系統(tong)無升壓(ya)變(bian)壓(ya)器直接(jie)接(jie)入10kV電網(wang)，額定功率為2MW，儲能(neng)容量為2MWh。
風(feng)(feng)電(dian)(dian)場(chang)建設規模為(wei)49.5MW，單(dan)機容量為(wei)1500kW的風(feng)(feng)電(dian)(dian)機組33臺(tai)。風(feng)(feng)電(dian)(dian)場(chang)海拔3500米。風(feng)(feng)電(dian)(dian)發電(dian)(dian)項目受天氣影(ying)響，電(dian)(dian)壓(ya)幅值波動較大，功(gong)率因數低。加裝35kV降壓(ya)式±8Mvar SVG+7Mvar FC濾波支路，實現(xian)-1~15Mvar的動態無功(gong)出力。
風(feng)電(dian)(dian)場建設規模為100MW，采用單機(ji)容量為2500kW的(de)(de)風(feng)電(dian)(dian)機(ji)組40臺，海拔2000米。風(feng)電(dian)(dian)發電(dian)(dian)項(xiang)目受天氣影響，電(dian)(dian)壓幅值(zhi)波動較大，功(gong)率因數低(di)。在35kV母線加裝1套35kV直(zhi)掛式 40Mvar水(shui)冷SVG，實現-40~+40Mvar的(de)(de)動態(tai)無功(gong)出力。
原(yuan)有(you)消弧線(xian)(xian)圈(quan)(quan)容量不足，接地(di)時(shi)(shi)選線(xian)(xian)裝置準確率低僅為(wei)60%左右(you)，導致相關(guan)的配網自動(dong)化系統在接地(di)故障(zhang)時(shi)(shi)無法發揮效用。本(ben)次技(ji)改通過將原(yuan)有(you)消弧線(xian)(xian)圈(quan)(quan)更換(huan)為(wei)消弧線(xian)(xian)圈(quan)(quan)并聯(lian)小電阻(zu)接地(di)成套裝置，接地(di)持續時(shi)(shi)間長于(yu)10s的故障(zhang)通過將...
